The client sends an HTTP request with a Content- Length header containing '+\\ '-' or an uncommon shell whitespace character prefix to the length field-value. This update also includes several other improvements to the HttpHeader parsing code.\n\nCVE-2020-15810 and CVE-2020-15811\n\nDue to incorrect data validation, HTTP Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning and allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches with content from an arbitrary source. When configured for relaxed header parsing (the default), Squid relays headers containing whitespace characters to upstream servers. When this occurs as a prefix to a Content-Length header, the frame length specified will be ignored by Squid (allowing for a conflicting length to be used from another Content-Length header) but relayed upstream.\n\nCVE-2020-24606\n\nSquid allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message.

It allows a crafted FTP server to trigger disclosure of\n sensitive information from heap memory, such as information associated with other users' sessions or non-\n Squid processes. (CVE-2019-12528)\n\n - An issue was discovered in http/ContentLengthInterpreter.cc in Squid before 4.12 and 5.x before 5.0.3. A\n Request Smuggling and Poisoning attack can succeed against the HTTP cache. The client sends an HTTP\n request with a Content-Length header containing +\\ - or an uncommon shell whitespace character prefix\n to the length field-value. (CVE-2020-15049)\n\n - An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP\n Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This\n allows any client, including browser scripts, to bypass local security and poison the proxy cache and any\n downstream caches with content from an arbitrary source. When configured for relaxed header parsing (the\n default), Squid relays headers containing whitespace characters to upstream servers. When this occurs as a\n prefix to a Content-Length header, the frame length specified will be ignored by Squid (allowing for a\n conflicting length to be used from another Content-Length header) but relayed upstream. (CVE-2020-15810)\n\n - An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP\n Request Splitting attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This\n allows any client, including browser scripts, to bypass local security and poison the browser cache and\n any downstream caches with content from an arbitrary source. Squid uses a string search instead of parsing\n the Transfer-Encoding header to find chunked encoding. This allows an attacker to hide a second request\n inside Transfer-Encoding: it is interpreted by Squid as chunked and split out into a second request\n delivered upstream. Squid will then deliver two distinct responses to the client, corrupting any\n downstream caches. (CVE-2020-15811)\n\n - Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all\n available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when\n cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply()\n livelocking in peer_digest.cc mishandles EOF. (CVE-2020-24606)\n\n - An issue was discovered in Squid before 4.10. Due to incorrect input validation, it can interpret crafted\n HTTP requests in unexpected ways to access server resources prohibited by earlier security filters.\n (CVE-2020-8449)\n\n - An issue was discovered in Squid before 4.10.

"cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2023-05-18T15:29:48", "description": "The remote SUSE Linux SLES11 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14460-1 advisory.\n\n - An issue was discovered in Squid through 4.7. When handling the tag esi:when when ESI is enabled, Squid calls ESIExpression::Evaluate. This function uses a fixed stack buffer to hold the expression while it's being evaluated. When processing the expression, it could either evaluate the top of the stack, or add a new member to the stack. When adding a new member, there is no check to ensure that the stack won't overflow. (CVE-2019-12519)\n\n - An issue was discovered in Squid through 4.7 and 5. When receiving a request, Squid checks its cache to see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request.\n If found, it servers the request. The absolute URL can include the decoded UserInfo (username and password) for certain protocols. This decoded info is prepended to the domain. This allows an attacker to provide a username that has special characters to delimit the domain, and treat the rest of the URL as a path or query string. An attacker could first make a request to their domain using an encoded username, then when a request for the target domain comes in that decodes to the exact URL, it will serve the attacker's HTML instead of the real HTML. On Squid servers that also act as reverse proxies, this allows an attacker to gain access to features that only reverse proxies can use, such as ESI. (CVE-2019-12520)\n\n - An issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it's off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can't affect adjacent memory blocks, and thus just leads to a crash while processing.\n (CVE-2019-12521)\n\n - An issue was discovered in Squid before 4.9. When handling a URN request, a corresponding HTTP request is made. This HTTP request doesn't go through the access checks that incoming HTTP requests go through. This causes all access checks to be bypassed and allows access to restricted HTTP servers, e.g., an attacker can connect to HTTP servers that only listen on localhost. (CVE-2019-12523)\n\n - An issue was discovered in Squid through 4.7. When handling requests from users, Squid checks its rules to see if the request should be denied. Squid by default comes with rules to block access to the Cache Manager, which serves detailed server information meant for the maintainer. This rule is implemented via url_regex. The handler for url_regex rules URL decodes an incoming request. This allows an attacker to encode their URL to bypass the url_regex check, and gain access to the blocked resource. (CVE-2019-12524)\n\n - An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it performs a memcpy of its length minus 2. Squid never checks whether the value is just a single quote (which would satisfy its requirements), leading to a memcpy of its length minus 1. (CVE-2019-12525)\n\n - An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in the heap. (CVE-2019-12526)\n\n - An issue was discovered in Squid before 4.10. It allows a crafted FTP server to trigger disclosure of sensitive information from heap memory, such as information associated with other users' sessions or non- Squid processes. (CVE-2019-12528)\n\n - An issue was discovered in Squid 2.x through 2.7.STABLE9, 3.x through 3.5.28, and 4.x through 4.7. When Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode.\n uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn't greater than the input buffer. This leads to adjacent memory being decoded as well. An attacker would not be able to retrieve the decoded data unless the Squid maintainer had configured the display of usernames on error pages. (CVE-2019-12529)\n\n - The cachemgr.cgi web module of Squid through 4.7 has XSS via the user_name or auth parameter.\n (CVE-2019-13345)\n\n - An issue was discovered in Squid 3.x and 4.x through 4.8. Due to incorrect input validation, there is a heap-based buffer overflow that can result in Denial of Service to all clients using the proxy. Severity is high due to this vulnerability occurring before normal security checks; any remote client that can reach the proxy port can trivially perform the attack via a crafted URI scheme. (CVE-2019-18676)\n\n - An issue was discovered in Squid 3.x and 4.x through 4.8 when the append_domain setting is used (because the appended characters do not properly interact with hostname length restrictions). Due to incorrect message processing, it can inappropriately redirect traffic to origins it should not be delivered to.\n (CVE-2019-18677)\n\n - An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content at arbitrary URLs. Effects are isolated to software between the attacker client and Squid. There are no effects on Squid itself, nor on any upstream servers. The issue is related to a request header containing whitespace between a header name and a colon. (CVE-2019-18678)\n\n - An issue was discovered in Squid 2.x, 3.x, and 4.x through 4.8. Due to incorrect data management, it is vulnerable to information disclosure when processing HTTP Digest Authentication. Nonce tokens contain the raw byte value of a pointer that sits within heap memory allocation. This information reduces ASLR protections and may aid attackers isolating memory areas to target for remote code execution attacks.\n (CVE-2019-18679)\n\n - Squid before 4.9, when certain web browsers are used, mishandles HTML in the host (aka hostname) parameter to cachemgr.cgi. (CVE-2019-18860)\n\n - An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials). (CVE-2020-11945)\n\n - An issue was discovered in Squid 5.x before 5.0.3. Due to an Incorrect Synchronization, a Denial of Service can occur when processing objects in an SMP cache because of an Ipc::Mem::PageStack::pop ABA problem during access to the memory page/slot management list. (CVE-2020-14059)\n\n - An issue was discovered in http/ContentLengthInterpreter.cc in Squid before 4.12 and 5.x before 5.0.3. A Request Smuggling and Poisoning attack can succeed against the HTTP cache. The client sends an HTTP request with a Content-Length header containing +\\ - or an uncommon shell whitespace character prefix to the length field-value. (CVE-2020-15049)\n\n - An issue was discovered in Squid before 4.10. Due to incorrect input validation, it can interpret crafted HTTP requests in unexpected ways to access server resources prohibited by earlier security filters.\n (CVE-2020-8449)\n\n - An issue was discovered in Squid before 4.10. Due to incorrect buffer management, a remote client can cause a buffer overflow in a Squid instance acting as a reverse proxy. (CVE-2020-8450)\n\n - An issue was discovered in Squid before 4.10.

When handling the tag esi:when when ESI is enabled, Squid\n calls ESIExpression::Evaluate. This function uses a fixed stack buffer to hold the expression while it's\n being evaluated. When processing the expression, it could either evaluate the top of the stack, or add a\n new member to the stack. When adding a new member, there is no check to ensure that the stack won't\n overflow. (CVE-2019-12519)\n\n - An issue was discovered in Squid through 4.7 and 5. When receiving a request, Squid checks its cache to\n see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request.\n If found, it servers the request. The absolute URL can include the decoded UserInfo (username and\n password) for certain protocols. This decoded info is prepended to the domain. This allows an attacker to\n provide a username that has special characters to delimit the domain, and treat the rest of the URL as a\n path or query string. An attacker could first make a request to their domain using an encoded username,\n then when a request for the target domain comes in that decodes to the exact URL, it will serve the\n attacker's HTML instead of the real HTML. On Squid servers that also act as reverse proxies, this allows\n an attacker to gain access to features that only reverse proxies can use, such as ESI. (CVE-2019-12520)\n\n - An issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in\n ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is\n parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this\n buffer, but it's off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same\n structure so it can't affect adjacent memory blocks, and thus just leads to a crash while processing.\n (CVE-2019-12521)\n\n - An issue was discovered in Squid before 4.9. When handling a URN request, a corresponding HTTP request is\n made. This HTTP request doesn't go through the access checks that incoming HTTP requests go through. This\n causes all access checks to be bypassed and allows access to restricted HTTP servers, e.g., an attacker\n can connect to HTTP servers that only listen on localhost. (CVE-2019-12523)\n\n - An issue was discovered in Squid through 4.7. When handling requests from users, Squid checks its rules to\n see if the request should be denied. Squid by default comes with rules to block access to the Cache\n Manager, which serves detailed server information meant for the maintainer. This rule is implemented via\n url_regex. The handler for url_regex rules URL decodes an incoming request. This allows an attacker to\n encode their URL to bypass the url_regex check, and gain access to the blocked resource. (CVE-2019-12524)\n\n - An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. When Squid is configured to use\n Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as\n domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it\n performs a memcpy of its length minus 2. Squid never checks whether the value is just a single quote\n (which would satisfy its requirements), leading to a memcpy of its length minus 1. (CVE-2019-12525)\n\n - An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based\n buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to\n ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in\n the heap. (CVE-2019-12526)\n\n - An issue was discovered in Squid before 4.10. It allows a crafted FTP server to trigger disclosure of\n sensitive information from heap memory, such as information associated with other users' sessions or non-\n Squid processes. (CVE-2019-12528)\n\n - An issue was discovered in Squid 2.x through 2.7.STABLE9, 3.x through 3.5.28, and 4.x through 4.7. When\n Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode.\n uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The\n length is then used to start decoding the string. There are no checks to ensure that the length it\n calculates isn't greater than the input buffer. This leads to adjacent memory being decoded as well. An\n attacker would not be able to retrieve the decoded data unless the Squid maintainer had configured the\n display of usernames on error pages. (CVE-2019-12529)\n\n - The cachemgr.cgi web module of Squid through 4.7 has XSS via the user_name or auth parameter.\n (CVE-2019-13345)\n\n - An issue was discovered in Squid 3.x and 4.x through 4.8. Due to incorrect input validation, there is a\n heap-based buffer overflow that can result in Denial of Service to all clients using the proxy. Severity\n is high due to this vulnerability occurring before normal security checks; any remote client that can\n reach the proxy port can trivially perform the attack via a crafted URI scheme. (CVE-2019-18676)\n\n - An issue was discovered in Squid 3.x and 4.x through 4.8 when the append_domain setting is used (because\n the appended characters do not properly interact with hostname length restrictions). Due to incorrect\n message processing, it can inappropriately redirect traffic to origins it should not be delivered to.\n (CVE-2019-18677)\n\n - An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests\n through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The\n resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content\n at arbitrary URLs. Effects are isolated to software between the attacker client and Squid. There are no\n effects on Squid itself, nor on any upstream servers. The issue is related to a request header containing\n whitespace between a header name and a colon. (CVE-2019-18678)\n\n - An issue was discovered in Squid 2.x, 3.x, and 4.x through 4.8. Due to incorrect data management, it is\n vulnerable to information disclosure when processing HTTP Digest Authentication. Nonce tokens contain the\n raw byte value of a pointer that sits within heap memory allocation. This information reduces ASLR\n protections and may aid attackers isolating memory areas to target for remote code execution attacks.\n (CVE-2019-18679)\n\n - Squid before 4.9, when certain web browsers are used, mishandles HTML in the host (aka hostname) parameter\n to cachemgr.cgi. (CVE-2019-18860)\n\n - An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest\n Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the\n attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if\n the pooled token credentials are freed (instead of replayed as valid credentials). (CVE-2020-11945)\n\n - An issue was discovered in Squid 5.x before 5.0.3. Due to an Incorrect Synchronization, a Denial of\n Service can occur when processing objects in an SMP cache because of an Ipc::Mem::PageStack::pop ABA\n problem during access to the memory page/slot management list. (CVE-2020-14059)\n\n - An issue was discovered in http/ContentLengthInterpreter.cc in Squid before 4.12 and 5.x before 5.0.3. A\n Request Smuggling and Poisoning attack can succeed against the HTTP cache. The client sends an HTTP\n request with a Content-Length header containing +\\ - or an uncommon shell whitespace character prefix\n to the length field-value. (CVE-2020-15049)\n\n - An issue was discovered in Squid before 4.10. Due to incorrect input validation, it can interpret crafted\n HTTP requests in unexpected ways to access server resources prohibited by earlier security filters.\n (CVE-2020-8449)\n\n - An issue was discovered in Squid before 4.10. Due to incorrect buffer management, a remote client can\n cause a buffer overflow in a Squid instance acting as a reverse proxy. (CVE-2020-8450)\n\n - An issue was discovered in Squid before 4.10. Due to incorrect input validation, the NTLM authentication\n credentials parser in ext_lm_group_acl may write to memory outside the credentials buffer. On systems with\n memory access protections, this can result in the helper process being terminated unexpectedly. This leads\n to the Squid process also terminating and a denial of service for all clients using the proxy.\n (CVE-2020-8517)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1140738\");\n script_set_attribute(attribute:\"see_also\",

When configured for\n relaxed header parsing (the default), Squid relays headers\n containing whitespace characters to upstream servers. When this\n occurs as a prefix to a Content-Length header, the frame length\n specified will be ignored by Squid (allowing for a conflicting\n length to be used from another Content-Length header) but relayed\n upstream.\n* [CVE-2020-24606](https://security-tracker.debian.org/tracker/CVE-2020-24606)\nSquid allows a trusted peer to perform Denial of Service by\n consuming all available CPU cycles during handling of a crafted\n Cache Digest response message.

When configured for\n relaxed header parsing (the default), Squid relays headers\n containing whitespace characters to upstream servers. When this\n occurs as a prefix to a Content-Length header, the frame length\n specified will be ignored by Squid (allowing for a conflicting\n length to be used from another Content-Length header) but relayed\n upstream.\n\nCVE-2020-24606\n\n Squid allows a trusted peer to perform Denial of Service by\n consuming all available CPU cycles during handling of a crafted\n Cache Digest response message.

It allows a crafted FTP server to trigger disclosure of sensitive information from heap memory, such as information associated with other users' sessions or non-Squid processes. (CVE-2019-12528)\n\nAn issue was discovered in http/ContentLengthInterpreter.cc in Squid before 4.12 and 5.x before 5.0.3. A Request Smuggling and Poisoning attack can succeed against the HTTP cache. The client sends an HTTP request with a Content-Length header containing \"+\\ \"-\" or an uncommon shell whitespace character prefix to the length field-value. (CVE-2020-15049)\n\nA flaw was found in squid. Due to incorrect data validation, a HTTP Request Smuggling attack against HTTP and HTTPS traffic is possible leading to cache poisoning. The highest threat from this vulnerability is to data confidentiality and integrity. (CVE-2020-15810)\n\nA flaw was found in squid. Due to incorrect data validation, an HTTP Request Splitting attack against HTTP and HTTPS traffic is possible leading to cache poisoning. The highest threat from this vulnerability is to data confidentiality and integrity. (CVE-2020-15811)\n\nSquid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF. (CVE-2020-24606)\n\nAn issue was discovered in Squid before 4.10. Due to incorrect input validation, it can interpret crafted HTTP requests in unexpected ways to access server resources prohibited by earlier security filters. (CVE-2020-8449)\n\nAn issue was discovered in Squid before 4.10. Due to incorrect buffer management, a remote client can cause a buffer overflow in a Squid instance acting as a reverse proxy.

URN response processing in Squid suffers from heap based buffer overflow.

When Squid is configured to use basic authentication, the Proxy-Authorization header is analyzed using uudecode. uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to make sure that the calculated length does not exceed the size of the input buffer. This results in decoding and contiguous memory. An attacker will not be able to get the decoded data unless the Squid maintainer has configured to display user names on error pages. \nCVE-STATUS: by default\nCVE-REV: by default\n \n \nCVE-ID: CVE-2019-12523\nCVE-Crit: CRITICAL\nCVE-DESC: problem has been detected in Squid before version 4.9. When a URN request is processed, the corresponding HTTP request is executed. This HTTP request does not pass the access checks that incoming HTTP requests pass. This bypasses all access checks and allows access to limited HTTP servers, for example, an attacker can connect to HTTP servers that only listen to localhost. \nCVE-STATUS: by default\nCVE-REV: by default\n \n \nCVE-ID: CVE-2019-12524\nCVE-Crit: CRITICAL\nCVE-DESC: The problem has been detected in Squid before version 4.7. When handling requests from users, Squid checks its rules to see if the request should be denied. Squid by default comes with rules to block access to Cache Manager which gives details of the server for service personnel. This rule is implemented through url_regex. The url_regex URL rule handler decodes the incoming request. This allows an attacker to encode their URL to bypass the url_regex check and gain access to the blocked resource. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2019-12521\nCVE-Crit: MEDIUM\nCVE-DESC: The problem has been detected in Squid before version 4.7. When Squid parses ESI, it stores ESI items in ESIContext. The ESIContext contains a buffer to store the ESIElements stack. When a new ESIElement is parsed, it is added via addStackElement. The addStackElement has a check for the number of elements in this buffer, but it is disabled at 1, which causes the heap 1 element to overflow. The overflow is in the same structure, so it cannot affect adjacent memory blocks and thus just causes a failure during processing. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2019-12520\nCVE-Crit: HIGH\nCVE-DESC: The problem has been detected in Squid through 4.7 and 5. When it receives a request, Squid checks its cache to see if it can process the response. It does this by creating an MD5 hash of the absolute URL of the request. If it is found, it serves the request. The absolute URL may include decoded UserInfo (username and password) for certain protocols. This decoded information is added to the domain. This allows the attacker to specify the username with special characters to separate the domain and treat the rest of the URL as a path or query string. An attacker can first make a request to its domain using the encoded username, and then when a request comes in for the target domain, which is decoded with the exact URL, it will serve the attacker's HTML instead of the actual HTML. On Squid servers, which also act as reverse proxies, this allows the attacker to access features that can only use reverse proxies, such as ESI. \nCVE-STATUS: by default\nCVE-REV: by default\n \n \nCVE-ID: CVE-2019-12522\nCVE-Crit: MEDIUM\nCVE-DESC: The problem has been detected in Squid before version 4.7. When Squid is started as root, it spawns its child processes as a lesser user, by default it is a nobody user. This is done with a leave_suid call. The leave_suid leaves the saved UID as 0. This makes it trivial for an attacker who has compromised a child process to escalate its privileges to root. \nCVE-STATUS: by default\nCVE-REV: by default\n \n \nCVE-ID: CVE-2019-18677\nCVE-Crit: MEDIUM\nCVE-DESC: a problem has been detected in Squid 3.x and 4.x - 4.8 when using the append_domain parameter (because the added characters do not interact properly with hostname length restrictions). Due to improper message handling, it may not properly redirect traffic to sources it should not be delivered to. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2019-18678\nCVE-Crit: MEDIUM\nCVE-DESC: The problem has been detected in Squid 3.x and 4.x to 4.8. It allows attackers to pass HTTP requests through the interface software to a Squid instance which shares the HTTP request pipeline differently. The resulting Response messages corrupt caches (between the client and Squid) of attacker-controlled content at arbitrary URLs. The impact on the software is isolated between the attacker and Squid. It does not affect Squid itself or any upstream servers. The problem is related to the request header containing spaces between the header name and the colon. \nCVE-STATUS: by default\nCVE-REV: by default\n \n \nCVE-ID: CVE-2019-18679\nCVE-Crit: HIGH\nCVE-DESC: The problem has been detected in Squid 2.x, 3.x and 4.x - 4.8. Due to improper data management, it is vulnerable to information disclosure when processing HTTP digest authentication. Nonce markers contain the raw byte value of a pointer located in allocated heap memory. This information reduces ASLR protection and can help attackers isolate memory areas for remote code execution attacks. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2019-18860\nCVE-Crit: MEDIUM\nCVE-DESC: Squid before 4.9, when using certain web browsers, does not handle HTML correctly in the host parameter (also known as hostname) in cachemgr.cgi. \nCVE-STATUS: by default\nCVE-REV: by default\n \n \nCVE-ID: CVE-2019-18676\nCVE-Crit: HIGH\nCVE-DESC: The problem has been detected in Squid 3.x and 4.x - 4.8. Due to improper input validation, a heap-based buffer overflow occurs, which can result in denial of service for all clients using the proxy. The severity is high because this vulnerability occurs before normal security checks; any remote client that can contact the proxy port can easily perform an attack through the URI scheme created. \nCVE-STATUS: default\nCVE-REV: by default\n \n \nCVE-ID: CVE-2020-15811\nCVE-Crit: MEDIUM\nCVE-DESC: The problem was detected in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, attacks with split HTTP requests can succeed for HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client including browser scripts to bypass local security and poison the browser cache and any subsequent caches with content from an arbitrary source. Squid uses string search instead of Transfer-Encoding header analysis to look for fragmented encoding. This allows the attacker to hide the second request within Transfer-Encoding: it is interpreted by Squid as fragmented and split into a second request delivered upstream. Squid will then send two different responses to the client, corrupting all the downstream caches. \nCVE-STATUS: by default\nCVE-REV: The default\n \n \nCVE-ID: CVE-2020-15810\nCVE-Crit: MEDIUM\nCVE-DESC: The problem has been detected in Squid before 4.13 and 5.x before 5.0.4. Due to improper data validation, HTTP request smuggling attacks can succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the proxy cache and any subsequent caches with content from an arbitrary source. When configured for simplified parsing of headers (the default), Squid retransmits headers containing space characters to upstream servers. When this occurs as a prefix to the Content-Length header, the specified frame length will be ignored by Squid (allowing the conflicting length from another Content-Length header to be used), but retransmitted upstream. \nCVE-STATUS: by default\nCVE-REV: by default\n \n \nCVE-ID: CVE-2020-14058\nCVE-Crit: HIGH\nCVE-DESC: The problem has been detected in Squid before 4.12 and 5.x before 5.0.3. Due to the use of a potentially dangerous feature, Squid and the default certificate validation assistant are vulnerable to denial of service when opening a TLS connection to a maliciously controlled server for HTTPS. This happens because unrecognized error values are displayed as NULL, but later code expects each error value to be mapped to a valid error string. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2020-15049\nCVE-Crit: HIGH\nCVE-DESC: problem was found in http / ContentLengthInterpreter.cc in Squid before 4.12 and 5.x before 5.0.3.
