The vulnerability then continued to exist for 5 years until it was fixed as an in-the-wild zero-day in January 2022.\"\n\nWhile both the [2013](<https://github.com/WebKit/WebKit/commit/4b3be1d3a8d22cb2b2f5ddb8299f7cd25a21cebf>) and [2022](<https://github.com/WebKit/WebKit/commit/aa31b6b4d09b09acdf1cec11f2f7f35bd362dd0e>) bugs in the [History API](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2022/CVE-2022-22620.html>) are essentially the same, the paths to trigger the vulnerability are different. Then subsequent code changes undertaken years later revived the zero-day flaw from the dead like a \"zombie.\"\n\nStating the incident is not unique to Safari, Stone further stressed taking adequate time to audit code and patches to avoid instances of having to duplicate the fixes and understand the security impacts of the changes being carried out.\n\n\"Both the October 2016 and the December 2016 commits were very large. The commit in October changed 40 files with 900 additions and 1225 deletions. The commit in December changed 95 files with 1336 additions and 1325 deletions,\" Stone noted.\n\n\"It seems untenable for any developers or reviewers to understand the security implications of each change in those commits in detail, especially since they're related to lifetime semantics.\"\n\n \n\n\nFound this article interesting?

giant Apple on Monday rolled out updates to remediate a zero-day flaw in iOS and iPadOS that it said has been actively exploited in the wild.\n\nThe weakness, given the identifier [CVE-2022-42827](<https://support.apple.com/en-us/HT213489>), has been described as an out-of-bounds write issue in the Kernel, which could be abused by a rogue application to execute arbitrary code with the highest privileges.\n\nSuccessful exploitation of [out-of-bounds write](<https://cwe.mitre.org/data/definitions/787.html>) flaws, which typically occur when a program attempts to write data to a memory location that's outside of the bounds of what it is allowed to access, can result in corruption of data, a crash, or execution of unauthorized code.\n\nThe iPhone maker said it addressed the bug with improved bounds checking, while crediting an anonymous researcher for reporting the vulnerability.\n\nAs is usually the case with actively exploited zero-day flaws, Apple refrained from sharing more specifics about the shortcoming other than acknowledging that it's \"aware of a report that this issue may have been actively exploited.\"\n\nCVE-2022-42827 is the third consecutive Kernel-related out-of-bounds memory vulnerability to be patched by Apple after [CVE-2022-32894](<https://thehackernews.com/2022/08/apple-releases-security-updates-to.html>) and [CVE-2022-32917](<https://thehackernews.com/2022/09/apple-releases-ios-and-macos-updates-to.html>), the latter two of which have also been previously reported to be weaponized in real-world attacks.\n\nThe security update is available for iPhone 8 and later, iPad Pro (all models), iPad Air 3rd generation and later, iPad 5th generation and later, and iPad mini 5th generation and later.\n\nWith the latest fix, Apple has closed out eight actively exploited zero-day flaws and one publicly-known zero-day vulnerability since the start of the year -\n\n * [**CVE-2022-22587**](<https://thehackernews.com/2022/01/apple-releases-ios-and-ipados-updates.html>) (IOMobileFrameBuffer) \u2013 A malicious application may be able to execute arbitrary code with

\u2013 An application may be able to read kernel memory\n * [**CVE-2022-22675**](<https://thehackernews.com/2022/03/apple-issues-patches-for-2-actively.html>) (AppleAVD) \u2013 An application may be

crafted web content may lead to arbitrary code execution\n * [**CVE-2022-32894**](<https://thehackernews.com/2022/08/apple-releases-security-updates-to.html>) (Kernel) \u2013 An application may be

able to execute arbitrary code with kernel privileges\n\nAside from CVE-2022-42827, the update also addresses 19 other security vulnerabilities, including two in Kernel, three in Point-to-Point Protocol (PPP), two in WebKit, and one each in AppleMobileFileIntegrity, Core Bluetooth, IOKit, Sandbox, and more.\n\n**_Update:_** Apple on Thursday backported fixes for the actively exploited iOS zero-day flaw (CVE-2022-42827) to older devices as part of [iOS and iPadOS 15.7.1](<https://support.apple.com/en-us/HT213490>) updates, along with patches for 17 other vulnerabilities.\n\nThe list of impacted devices consist of iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation)\n\nThe tech giant also [revised the advisory](<https://support.apple.com/en-us/HT213489>) it issued earlier this week for iOS 16.1 and iPadOS 16 to include 15 more new flaws, including four issues in the Kernel and others in Apple Neural Engine, FaceTime, Graphics Driver, and zlib, taking the total number of fixes to 36.\n\n \n\n\nFound this article interesting?

Apple noted it addressed the bug with improved state handling.\n\nThe update, which is available with [iOS 15.7.2, iPadOS 15.7.2](<https://support.apple.com/en-us/HT213531>), [macOS Ventura 13.1](<https://support.apple.com/en-us/HT213532>), [tvOS 16.2](<https://support.apple.com/en-us/HT213535>), and [Safari 16.2](<https://support.apple.com/en-us/HT213537>), arrives two weeks after Apple patched the same bug in [iOS 16.1.2](<https://support.apple.com/en-us/HT213516>) on November 30, 2022.\n\nThe fix marks the resolution of the tenth zero-day vulnerability discovered in Apple software since the start of the year.

According to the security update information provided by [Apple](<https://support.apple.com/en-us/HT213092>) the vulnerability exists in WebKit\u2014the HTML rendering engine component of its Safari browser\u2014and can be used by an attacker to create web content that may lead to arbitrary code execution.\n\nApple says it has addressed this vulnerability with improved memory management in iOS 15.3.1, iPadOS 15.3.1, macOS Monterey 12.2.1, and Safari 15.3.\n\n### Vulnerability\n\nThe vulnerability is a use-after-free (UAF) issue in WebKit that could lead to OS crashes and code execution on compromised devices. Use after free (UAF) is a type of vulnerability that results from the incorrect use of dynamic memory during a program\u2019s operation. If, after freeing a memory location, a program does not clear the pointer to that memory, an attacker can use the error to manipulate the program. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code.\n\nThis issue can be exploited when WebKit processes HTML content. The attacker can exploit this vulnerability by luring users to visit a specially crafted web page. Once the user opens the malicious web page, an attacker can remotely execute malicious code on the targeted system. The vulnerability has been reported publicly as being exploited in the wild and was reported by an anonymous researcher.\n\nWebKit is the browser engine that powers Safari on Macs as well as all browsers on iOS and iPadOS (browsers on iOS and iPadOS are obliged to use it). It is also the web browser engine used by Mail, App Store, and many other apps on macOS, iOS, and Linux. \n\n### Affected devices\n\nUsers owning the following devices should install the update as soon as possible:\n\n * iOS 15.3.1 and iPadOS 15.3.1 can be found on iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation).\n * macOS Monterey 12.2.1 for all systems running macOS Monterey (MacBooks, iMacs, Mac minis, and Mac Pros)\n * All devices running macOS Big Sur and macOS Catalina which are using Safari.\n\nStay safe, everyone!\n\nThe post [Update now!

This class of cyber sabotage can spy on, disrupt, or destroy systems that manage large-scale industrial processes. An essential danger in this threat is that it moves from mere digital damage to risking human lives. In this post we will review the history of ICS malware, briefly examine how one ICS framework operates, and offer our advice on how to fight such threats.\n\nICS malware is usually sophisticated, requiring time to research its targets and sufficient resources. Attackers can be motivated by financial gain, hacktivism, or espionage, as well as for political ends, as we saw with Stuxnet. Since Stuxnet, researchers have discovered several industrial attacks; each year we seem to read about a worse threat than before.\n\nIn August 2017, a sophisticated malware targeted petrochemical facilities in the Middle East. The malware\u2014dubbed Triton, Trisis, or HatMan\u2014attacked safety instrumented systems (SIS), a critical component that has been designed to protect human life. The system targeted in that case was the Schneider Triconex SIS. The initial vector of infection is still unknown, but it was likely a phishing attack.\n\nAfter gaining remote access, the Triton attackers moved to disrupt, take down, or destroy the industrial process. The goal of the attackers is still unclear because the attack was discovered after an [accidental shutdown](<https://www.darkreading.com/attacks-breaches/triton-attacker-disrupts-ics-operations-while-botching-attempt-to-cause-physical-damage-/d/d-id/1330650>) of the plant led to further investigation. Investigations conducted by several security companies have revealed a complex malware framework embedding PowerPC shellcode (the Triconex architecture) and an implementation of the proprietary communication protocol TriStation. The malware allowed the attackers to easily communicate with safety controllers and remotely manipulate system memory to inject shellcodes; they completely controlled the target. However, because the attack did not succeed it is possible that a payload, the final stage of the attack, was missing. All investigations pointed in this direction. If the final payload had been delivered, the consequences could have been disastrous.\n\n## CVE-2022-22620: Apple finally gave something away for free!\n\nHistory of ICS malware \n\nIn 2010, Stuxnet was one of the most sophisticated ICS threats discovered. This cyber weapon was created to target Iranian centrifuges. It was able to reprogram a particular programmable logic controller to change the speed of centrifuge rotations. The goal of Stuxnet was not to destroy but to take the control of the industrial process.\n\nIn 2013, the malware Havex targeted energy grids, electricity firms, and many others. The attackers collected a large amount of data and remotely monitored industrial systems. Havex was created for espionage and sabotage.\n\nBlackEnergy was discovered in 2015. It targeted critical infrastructure and destroyed files stored on workstations and servers. In Ukraine, 230,000 people were left in the dark for six hours after hackers compromised several power distribution centers.\n\nIn 2015, IronGate was discovered on public sources. It targeted Siemens control systems and had functionalities similar to Stuxnet\u2019s. It is unclear if this was a proof of concept or a simple penetration-testing tool.\n\nIndustroyer hit Ukraine again in 2016. The malware embedded a data wiper component as well as a distributed denial of services module. It was crafted for destruction. The attack caused a second shutdown of Ukraine\u2019s power grid.\n\nIn 2017, Triton was discovered. The attack did not succeed; the consequences could have been disastrous.\n\n\n\nICS malware are critical because they infect industrial devices and automation. However, regular malware can also impact industrial process. Last year WannaCry forced several companies, from medical to automobile industries, to stop production. Some months later NotPetya hit nuclear power plants, power grids, and health care systems. In 2018, a cryptocurrency miner struck a water utility in Europe.\n\nFacing widespread risks, critical infrastructures need a specific approach to stay safe.\n\nICS malware are critical because they infect industrial devices and automation.

Some months later NotPetya hit nuclear power plants, power grids, and health care systems. In 2018, a cryptocurrency miner struck a water utility in Europe.\n\n### Triton framework\n\nTriton targeted the Triconex safety controller, distributed by Schneider Electric. Triconex safety controllers are used in 18,000 plants (nuclear, oil and gas refineries, chemical plants, etc.), according to the company. Attacks on SIS require a high level of process comprehension (by analyzing acquired documents, diagrams, device configurations, and network traffic). SIS are the last protection against a physical incident.\n\nThe attackers gained access to the network probably via spear phishing, according to an investigation. After the initial infection, the attackers moved onto the main network to reach the ICS network and target SIS controllers.\n\n\n\nTo communicate with SIS controllers, attackers recoded the proprietary TriStation communication protocol on port UDP/1502. This step suggests they invested the time to reverse engineer the Triconex product.\n\nNozomi Networks has created a [Wireshark dissector](<https://github.com/NozomiNetworks/tricotools>) that is very handy for analyzing the TriStation protocol and detecting a Triton attack. The following screenshot shows an example of the information returned by the Triconex SIS. Triton requires the \u201crunning state\u201d of the controller to perform the next stages of the attack.\n\n\n\nIn the preceding screen Triconex replies to the request \u201cGet Control Program Status,\u201d which is sent by Triton.\n\nThe Triton framework (dc81f383624955e0c0441734f9f1dabfe03f373c) posed as the legitimate executable trilog.exe, which collects logs. The executable is a python script compiled in an exe. The framework also contains library.zip (1dd89871c4f8eca7a42642bf4c5ec2aa7688fd5c), which contains all the python scripts required by Triton. Finally, two PowerPC shellcodes (the target architecture) are used to compromise the controllers. The first PowerPC shellcode is an injector (inject.bin, f403292f6cb315c84f84f6c51490e2e8cd03c686) used to inject the second stage (imain.bin, b47ad4840089247b058121e95732beb82e6311d0), the backdoor that allows read, write, and execute access on the Triconex product.\n\nThe following schema shows the main modules of Triton:\n\n\n\nThe missing payload has not been recovered during the forensic investigation. Because the attack was discovered early, it is possible that the attackers did not have time to launch the final stage.\n\n### How to detect an unusual network connection\n\n[Nozomi Networks has created a script](<https://github.com/NozomiNetworks/tricotools>) that simulates a Triconex safety controller. We modified this script with a Raspberry Pi to create a cheap detector tool.\n\n<br />\n\nThis inexpensive tool can be easily installed on an ICS network. If an illegitimate connection occurs, the device alerts with a blinking LED and siren. It also displays the IP address of the connection for further investigation.\n\nThe following picture shows how to connect the LED and buzzer.\n\n\n\n### Fighting ICS malware\n\nICS malware has become more aggressive and sophisticated. Many industrial devices were built before anyone imagined cyberattacks such as Triton. ICS\u2019s are now exposed to connected environments they were not designed for.\n\nStandard McAfee security recommendations (vulnerability patching, complex passwords, identification control, security tools, etc.) remain the same as for regular networks, yet industrial systems also require specific procedures due to their importance. Industrial networks must be segregated from general business networks, and every machine connected to the industrial process should be carefully monitored by using strict access control and application whitelisting.\n\nFurther security recommendations:\n\n * Segregate physical and logical access to ICS networks with strong authentication, including strong passwords and double factor, card readers, surveillance cameras, etc.\n * Use DMZ and firewall to prevent network traffic from passing between the corporate and the ICS network\n * Deploy strong security measures on the ICS network perimeter, including patch management, disabling unused ports, and restricting ICS user privileges\n * Log and monitor every action on the ICS network to quickly identify a point of failure\n * When possible implement redundancy on critical devices to avoid major issues\n * Develop strong security policies and an incident response plan to restore systems during an incident\n * Train people with simulated incident responses and security awareness\n\nAttackers learn what works from past attacks and from each other. Rapid developments in ICS threats make it crucial to stay protected. Manufacturers, plant operators, governments, and the cybersecurity industry must work together to avoid critical cyberattacks.\n\n### Indicators of compromise\n\n * dc81f383624955e0c0441734f9f1dabfe03f373c: trilog.exe\n * b47ad4840089247b058121e95732beb82e6311d0: imain.bin\n * f403292f6cb315c84f84f6c51490e2e8cd03c686: inject.bin\n * 91bad86388c68f34d9a2db644f7a1e6ffd58a449: script_test.py\n * 1dd89871c4f8eca7a42642bf4c5ec2aa7688fd5c: library.zip\n * 97e785e92b416638c3a584ffbfce9f8f0434a5fd: TS_cnames.pyc\n * d6e997a4b6a54d1aeedb646731f3b0893aee4b82: TsBase.pyc\n * 66d39af5d61507cf7ea29e4b213f8d7dc9598bed: TsHi.pyc\n * a6357a8792e68b05690a9736bc3051cba4b43227: TsLow.pyc\n * 2262362200aa28b0eead1348cb6fda3b6c83ae01: crc.pyc\n * 9059bba0d640e7eeeb34099711ff960e8fbae655: repr.pyc\n * 6c09fec42e77054ee558ec352a7cd7bd5c5ba1b0: select.pyc\n * 25dd6785b941ffe6085dd5b4dbded37e1077e222: sh.pyc\n\n### References\n\n * [https://blog.schneider-electric.com/cyber-security/2018/08/07/one-year-after-triton-building-ongoing-industry-wide-cyber-resilience/](<https://ics-cert.us-cert.gov/sites/default/files/ICSJWG-Archive/QNL_DEC_17/Waterfall_top-20-attacks-article-d2%20-%20Article_S508NC.pdf>)\n * [https://www.youtube.com/watch?v=f09E75bWvkk](<https://ics-cert.us-cert.gov/sites/default/files/ICSJWG-Archive/QNL_DEC_17/Waterfall_top-20-attacks-article-d2%20-%20Article_S508NC.pdf>)\n * <https://ics-cert.us-cert.gov/sites/default/files/ICSJWG-Archive/QNL_DEC_17/Waterfall_top-20-attacks-article-d2%20-%20Article_S508NC.pdf>\n * <https://www.fireeye.com/blog/threat-research/2017/12/attackers-deploy-new-ics-attack-framework-triton.html>\n * <https://www.midnightbluelabs.com/blog/2018/1/16/analyzing-the-triton-industrial-malware>\n * <https://www.nozominetworks.com/2018/07/18/blog/new-triton-analysis-tool-wireshark-dissector-for-tristation-protocol/>\n * <https://github.com/NozomiNetworks/tricotools>\n * <https://cyberx-labs.com/en/blog/triton-post-mortem-analysis-latest-ot-attack-framework/>\n * <https://vimeo.com/275906105>\n * <https://vimeo.com/248057640>\n * <https://blog.talosintelligence.com/2017/07/template-injection.html>\n * <https://github.com/MDudek-ICS/TRISIS-TRITON-HATMAN>\n", "cvss3": {}, "published": "2018-11-08T00:00:00", "type": "trellix", "title": "Triton Malware Spearheads Latest Attacks on Industrial Systems | McAfee Blogs", "bulletinFamily": "info", "cvss2": {}, "cvelist": ["CVE-2022-22620"], "modified": "2018-11-08T00:00:00", "id": "TRELLIX:4EE3028711C16E3513FC2CF300440452", "href": "https://www.trellix.com/content/mainsite/en-us/about/newsroom/stories/research/triton-malware-spearheads-latest-generation-of-attacks-on-industrial-systems.html", "cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2022-03-02T00:00:00", "description": "# The Bug Report - February 2022 \n\nBy Jesse Chick \u00b7 March 2, 2022\n\n## Your Cybersecurity Comic Relief\n\n[](<https://toggl.com/>) **[Image courtesy of https://toggl.com/](<https://toggl.com/>)**\n\n## Why am I here?\n\nWelcome back to the Bug Report, stubby-month edition! For those in the audience unfamiliar with our shtick, [every month](<https://www.trellix.com/en-us/about/newsroom/stories/threat-labs/the-bug-report-january-2022.html>) we compile a shortlist of the top vulnerabilities of the month, so that they might whittle away at your last few hours of peaceful sleep. \n\nIt\u2019s a testament to the excitement of the last few months that February came as something of a reprieve for many of us who follow the ebbs and flows of the vulnerability landscape. But as we all slow down and catch our breath, someone, somewhere is having their personal information leaked, their intellectual property held by ransomware, or their privacy otherwise abused by a 0-day...and you're probably here for the grisly details. So, we at Trellix dutifully present to you our four high-impact vulns released during the month of February:\n\n * CVE-2022-22620: Apple WebKit\n * CVE-2022-0609: Google Chrome\n * CVE-2022-24086: Magento/ Adobe Commerce \n * CVE-2022-22536: SAP Internet Communications Manager\n \n\n\n## CVE-2022-22620: Apple finally gave something away for free!\n\n### What is it?\n\nWebKit is Apple\u2019s browser engine. If you are browsing the internet using an Apple product, I\u2019d bet with next month\u2019s rent money that WebKit is churning behind the scenes. Versions of WebKit prior to iOS 15.3.1 contain a use-after-free vulnerability (which occurs due to shoddy memory management) that can allow full remote code execution on a victim\u2019s device. The avenue of attack most likely to be used by attackers is a malicious URL (remember phishing from those pesky compliance trainings?) or via embedding the payload in a cross-site scripting attack on a vulnerable webpage. In the same terse fashion we curious souls have come to expect, Apple has withheld further detail on this vulnerability and the nature of the exploit. \n\n### Who cares?\n\nI care. I have an iPhone. And so do [6 million](<https://securityboulevard.com/2022/02/apples-zero-day-0-click-critical-vulnerability-cve-2022-22620/>) of you on Twitter, apparently, who likely rely on Apple products for either professional or personal tasks. To make this threat even less abstract for us Apple used-to-be-elite-now-commoners, there have been [reports](<https://twitter.com/Laughing_Mantis/status/1494394742821425164>) of CVE-2022-22620 being exploited in conjunction with privilege escalation to gain access to users\u2019 cameras and microphones.\n\n### What can I do?\n\nUpdate. Gotta update, always. To make sure your iPhone is running the patched version of iOS, go to Settings > General > About. If the \u201cSoftware Version\u201d shows something older than 15.3.1, that device is vulnerable, and it would be best to update immediately.\n\n### The Gold Standard\n\nAt this point, patching via software update is your best option. If you would like to have security and other updates installed automatically overnight upon release by Apple, this can be configured on all relevant devices to ensure you are free of exposure as quickly as possible.\n\n \n\n\n## CVE-2022-0609: Should you switch to Firefox?\n\n### What is it?\n\nAppearing like roaches, use-after-free browser bugs travel in groups. This one was discovered in-house at Google, by the Threat Analysis Group, inside of Chrome\u2019s animation component. Although some interaction from the user is required to carry out a successful exploit, this vulnerability can be leveraged to send and execute commands on a victim\u2019s machine over a local network.\n\n### Who cares?\n\nThe hundreds of millions of Chrome users (backed by Chrome\u2019s nearly two-thirds market share among today\u2019s browsers) may want to pay it some mind. This especially holds true for those who often browse from a public network, e.g. students and those who frequently travel, since public networks are a common reservoir of targets for malicious actors. Sure enough, [according to Google](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-0609>), this vulnerability is reported to have been exploited numerous times in the wild. But we all work from home now so no big deal, right? (I\u2019m hoping this comment does NOT age well).\n\n### What can I do?\n\n[Update Chrome](<https://support.google.com/chrome/answer/95414?hl=en&co=GENIE.Platform%3DDesktop>) to version [98.0.4758.102](<https://chromereleases.googleblog.com/2022/02/stable-channel-update-for-desktop_14.html>) or later, if you have not done so already. Checking the current version of Chrome is as simple as pasting \u201cchrome://version\u201d into the search bar.\n\n### The Gold Standard\n\nAs with iOS, etc., turning on automatic updates for Chrome is a good practice. Set it and forget. \n\n \n\n\n## CVE-2022-24086: All your e-commerce belongs to\u2026.?\n\n### What is it?\n\nYou can be forgiven for having never heard of Magento; avoiding PHP back ends like Ebola seems like decent practice. It turns out Magento is an open-source e-commerce platform which was bought by Adobe in 2018 and now forms the backbone of Adobe Commerce. Due to a lack of proper input validation (CWE-20, if you care) during the checkout stage of a transaction, an attacker can use Adobe Commerce\u2014or the open-source release of Magento that parallels it\u2014to achieve unauthenticated RCE with the same privileges as the corresponding server process. So, if Magento is running as root, this is about as bad as it gets.\n\n### Who cares?\n\nWell, if your platform relies on Adobe Commerce or open-source Magento, consider yourself vulnerable\u2014all unpatched versions of each are affected. Not to mention, CVE-2022-24086 has been actively exploited in the wild.\n\nAs of this writing, there is no complete publicly-available proof of concept, although a redacted version of a working POC (seen below) created by researchers with [Positive Technologies Offensive Team](<https://swarm.ptsecurity.com/>) has been released on [Twitter](<https://twitter.com/ptswarm/status/1494240197915123713>) and distributed widely, which illustrates the leaking of \u201c/etc/passwd\u201d on a vulnerable host.\n\n \n\n\n### What can I do?\n\nPatch, and patch quickly. Time is of the essence! But be sure to follow the [instructions from Adobe](<https://helpx.adobe.com/security/products/magento/apsb22-12.html#Summary>) with care: there are two patches which must be applied in sequence, one to address [CVE-2022-24086](<https://vulners.com/cve/CVE-2022-24086>) and another to fix the near-identical follow-on issue tracked as [CVE-2022-24087](<https://sensorstechforum.com/cve-2022-24087-adobe-magento/>). Both patches are required to make sure that your platform is safe from exploitation of this vulnerability.\n\n### The Gold Standard\n\nStay abreast on the latest impactful vulnerabilities throughout the industry; or you just might see a piece of your own infrastructure featured in the latest CVE. Our [security bulletins](<https://www.mcafee.com/enterprise/en-us/threat-center/product-security-bulletins.html>) are a great place to start.\n\n \n\n\n## CVE-2022-22536: A Perfect 10!\n\n### What is it?\n\nDoes anyone have a clue what SAP stands for? I\u2019ve always wondered but never been able to demystify the potential acronym. This month it could be confused with a Strikingly Attackable Platform thanks to CVE-2022-22536. The bug exists in the SAP Internet Communication Manager (ICM) when the webserver hosting the ICM is sitting behind a proxy. An attacker can use a technique called [HTTP Response Smuggling](<https://www.whitehatsec.com/glossary/content/http-response-smuggling>) to poison the proxy\u2019s web cache and ICM response queue. Upon an unexpecting user visiting the website and making a GET request for the page, they will download the attacker\u2019s malicious JavaScript instead of the intended webpage. A more detailed (and colorful!) explanation of the attack mechanics is available on the [Onapsis website](<https://onapsis.com/icmad-sap-cybersecurity-vulnerabilities?utm_campaign=2022-Q1-global-ICM-campaign-page&utm_medium=website&utm_source=third-party&utm_content=CISA-alert#download>), for the price of your email, of course.\n\n### Who cares?\n\nSAP in January of 2022 proudly [reported](<https://www.sap.com/documents/2017/04/4666ecdd-b67c-0010-82c7-eda71af511fa.html>) that 99 of 100 of the largest companies in the world were SAP customers with over [230 million cloud users](<https://www.sap.com/about/company/what-is-sap.html>). Couple that statistic with the fact that every SAP application sitting behind any kind of proxy with standard configuration will be vulnerable to this bug, there is a good chance you might need to cancel your weekend plans. Although we don\u2019t put much stock in [CVSS score](<https://nvd.nist.gov/vuln-metrics/cvss>) for this publication, it's worth noting this scored the magical unicorn rating of a perfect 10 and was able to garner special attention from our friends at [CISA](<https://www.cisa.gov/uscert/ncas/current-activity/2022/02/08/critical-vulnerabilities-affecting-sap-applications-employing>).\n\n### What can I do?\n\nIf in doubt as to whether or not your SAP server is vulnerable, the good people at [Onapsis](<https://onapsis.com/>), who discovered the vulnerability, released a Python-based [scanning tool](<https://wiki.scn.sap.com/wiki/display/PSR/SAP+Security+Patch+Day+-+February+2022>) with a complete CLI. Or, if you have the version number of your NetWeaver, Web Dispatcher, etc., you can simply cross-reference it with [SAP\u2019s official list](<https://wiki.scn.sap.com/wiki/display/PSR/SAP+Security+Patch+Day+-+February+2022>) of vulnerable versions.

This allows us to then understand if it was fully fixed, look for variants, and brainstorm new mitigations. This blog is the story of a \u201czombie\u201d Safari 0-day and how it came back from the dead to be disclosed as exploited in-the-wild in 2022. CVE-2022-22620 was initially fixed in 2013, reintroduced in 2016, and then disclosed as exploited in-the-wild in 2022. If you\u2019re interested in the full root cause analysis for CVE-2022-22620, we\u2019ve published it [here](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2022/CVE-2022-22620.html>).\n\nIn the [2020 Year in Review of 0-days exploited in the wild](<https://googleprojectzero.blogspot.com/2021/02/deja-vu-lnerability.html>), I wrote how 25% of all 0-days detected and disclosed as exploited in-the-wild in 2020 were variants of previously disclosed vulnerabilities. Almost halfway through 2022 and it seems like we\u2019re seeing a similar trend. Attackers don\u2019t need novel bugs to effectively exploit users with 0-days, but instead can use vulnerabilities closely related to previously disclosed ones. This blog focuses on just one example from this year because it\u2019s a little bit different from other variants that we\u2019ve discussed before. Most variants we\u2019ve discussed previously exist due to incomplete patching. But in this case, the variant was completely patched when the vulnerability was initially reported in 2013. However, the variant was reintroduced 3 years later during large refactoring efforts. The vulnerability then continued to exist for 5 years until it was fixed as an in-the-wild 0-day in January 2022.\n\n# Getting Started\n\nIn the case of CVE-2022-22620 I had two pieces of information to help me figure out the vulnerability: [the patch](<https://github.com/WebKit/WebKit/commit/486816dc355c19f1de1b8056f85d0bbf7084dd6e>) (thanks to Apple for sharing with me!) and [the description from the security bulletin](<https://support.apple.com/en-us/HT213093>) stating that the vulnerability is a use-after-free. The primary change in the patch was to change the type of the second argument (stateObject) to the function FrameLoader::loadInSameDocument from a raw pointer, SerializedScriptValue* to a reference-counted pointer, RefPtr<SerializedScriptValue>.\n\n[trunk/Source/WebCore/loader/FrameLoader.cpp](<https://trac.webkit.org/changeset/288539/webkit/trunk/Source/WebCore/loader/FrameLoader.cpp>)\n\n| \n\n| \n \n---|---|--- \n \n1094\n\n| \n\n1094\n\n| \n\n// This does the same kind of work that didOpenURL does, except it relies on the fact \n \n1095\n\n| \n\n1095\n\n| \n\n// that a higher level already checked that the URLs match and the scrolling is the right thing to do. \n \n1096\n\n| \n\n| \n\nvoid FrameLoader::loadInSameDocument(const URL& url, SerializedScriptValue* stateObject, bool isNewNavigation) \n \n| \n\n1096\n\n| \n\nvoid FrameLoader::loadInSameDocument(URL url, RefPtr<SerializedScriptValue> stateObject, bool isNewNavigation) \n \nWhenever I\u2019m doing a root cause analysis on a browser in-the-wild 0-day, along with studying the code, I also usually search through commit history and bug trackers to see if I can find anything related. I do this to try and understand when the bug was introduced, but also to try and save time. (There\u2019s a lot of 0-days to be studied! \ud83d\ude00)\n\n# The Previous Life\n\nIn the case of CVE-2022-22620, I was scrolling through the [git ](<https://git-scm.com/docs/git-blame>)[blame](<https://git-scm.com/docs/git-blame>) view of FrameLoader.cpp. Specifically I was looking at the [definition of ](<https://github.com/WebKit/WebKit/blame/7b23cae2a1b1ffd026288f15261f8ba272c3b24b/Source/WebCore/loader/FrameLoader.cpp#L1096>)[loadInSameDocument](<https://github.com/WebKit/WebKit/blame/7b23cae2a1b1ffd026288f15261f8ba272c3b24b/Source/WebCore/loader/FrameLoader.cpp#L1096>). When looking at the git blame for this line prior to our patch, it\u2019s a very [interesting commit](<https://github.com/WebKit/WebKit/commit/aa31b6b4d09b09acdf1cec11f2f7f35bd362dd0e>). The commit was actually changing the stateObject argument from a reference-counted pointer, PassRefPtr<SerializedScriptValue>, to a raw pointer, SerializedScriptValue*. This change from December 2016 introduced CVE-2022-22620. The [Changelog even states](<https://github.com/WebKit/WebKit/commit/aa31b6b4d09b09acdf1cec11f2f7f35bd362dd0e#diff-9fb71b6fa7156160059b0216d05933e621d422df2b20f72ad7399eb946b8ba04>):\n\n \n(WebCore::FrameLoader::loadInSameDocument): Take a raw pointer for the\n\nserialized script value state object. No one was passing ownership.\n\nBut pass it along to statePopped as a Ref since we need to pass ownership\n\nof the null value, at least for now.\n\nNow I was intrigued and wanted to track down the previous commit that had changed the stateObject argument to PassRefPtr<SerializedScriptValue>. I was in luck and only had to go back in the history two more steps. There was a [commit from 2013](<https://github.com/WebKit/WebKit/commit/4b3be1d3a8d22cb2b2f5ddb8299f7cd25a21cebf>) that changed the stateObject argument from the raw pointer, SerializedScriptValue*, to a reference-counted pointer, PassRefPtr<SerializedScriptValue>. This commit from February 2013 was doing the same thing that our commit in 2022 was doing. The commit was titled \u201cUse-after-free in SerializedScriptValue::deserialize\u201d and included a good description of how that use-after-free worked.\n\nThe commit also included a test:\n\nAdded a test that demonstrated a crash due to use-after-free\n\nof SerializedScriptValue.\n\nTest: fast/history/replacestate-nocrash.html\n\nThe trigger from this test is:\n\nObject.prototype.__defineSetter__(\"foo\",function(){history.replaceState(\"\", \"\")});\n\nhistory.replaceState({foo:1,zzz:\"a\".repeat(1<<22)}, \"\");\n\nhistory.state.length; \n \n--- \n \nMy hope was that the test would crash the vulnerable version of WebKit and I\u2019d be done with my root cause analysis and could move on to the next bug. Unfortunately, it didn\u2019t crash.\n\nThe commit description included the comment to check out a Chromium bug. (During this time Chromium still used the WebKit rendering engine. Chromium forked[ the Blink rendering engine in April 2013](<https://blog.chromium.org/2013/04/blink-rendering-engine-for-chromium.html>).) I saw that my now Project Zero teammate, Sergei Glazunov, originally reported the [Chromium bug](<https://bugs.chromium.org/p/chromium/issues/detail?id=171839>) back in 2013, so I asked him for the details.\n\nThe use-after-free from 2013 (no CVE was assigned) was a bug in the implementation of the History API. This API allows access to (and modification of) a stack of the pages visited in the current frame, and these page states are stored as a SerializedScriptValue. The History API exposes a getter for state, and a method replaceState which allows overwriting the \"most recent\" history entry. \n \nThe bug was that in the implementation of the getter for state, SerializedScriptValue::deserialize was called on the current \"most recent\" history entry value without increasing its reference count. As SerializedScriptValue::deserialize could trigger a callback into user JavaScript, the callback could call replaceState to drop the only reference to the history entry value by replacing it with a new value. When the callback returned, the rest of SerializedScriptValue::deserialize ran with a free'd this pointer.\n\nIn order to fix this bug, it appears that the developers decided to change every caller of SerializedScriptValue::deserialize to increase the reference count on the stateObject by changing the argument types from a raw pointer to PassRefPtr<SerializedScriptValue>. While the originally reported trigger called deserialize on the stateObject through the V8History::stateAccessorGetter function, the developers\u2019 fix also caught and patched the path to deserialize through loadInSameDocument.\n\nThe timeline of the changes impacting the stateObject is:\n\n * [December 2009 - state object History API added.](<https://github.com/WebKit/WebKit/commit/e544495d282d4726fcb491e0e441ddba338b5ec1>)\n * HistoryItem.m_stateObject is type RefPtr<SerializedScriptValue>\n * HistoryItem::stateObject() returns SerializedScriptValue*\n * FrameLoader::loadInSameDocument takes stateObject argument as SerializedScriptValue*\n * [January 2013 - Patching Sergei\u2019s bug](<https://github.com/WebKit/WebKit/commit/4b3be1d3a8d22cb2b2f5ddb8299f7cd25a21cebf>)\n * HistoryItem::stateObject returns a PassRefPtr<SerializedScriptValue>\n * FrameLoader::loadInSameDocument takes stateObject argument as PassRefPtr<SerializedScriptValue>\n * [September 2015- Deprecating use of PassRefPtr in history directory](<https://github.com/WebKit/WebKit/commit/ec83a53b569f6c2b493e9874a498cd1b683656a1>)\n * HistoryItem::stateObject returns RefPtr instead of PassRefPtr\n * [October 2016 - (Potentially) ad-hoc refactoring ](<https://github.com/WebKit/WebKit/commit/ed43edee9f8f114c3b2db3c0420e23f926a968ee>)\n * HistoryItem::stateObject() is changed to return raw pointer instead of RefPtr\n * [December 2016 - CVE-2022-22600 introduced](<https://github.com/WebKit/WebKit/commit/aa31b6b4d09b09acdf1cec11f2f7f35bd362dd0e>)\n * FrameLoader::loadInSameDocument changed to take stateObject as a raw pointer instead of PassRefPtr<SerializedScriptValue>\n * [January 2022 - CVE-2022-22600 patched](<https://github.com/WebKit/WebKit/commit/486816dc355c19f1de1b8056f85d0bbf7084dd6e>)\n * FrameLoader::loadInSameDocument changed to take stateObject as a RefPtr<SerializedScriptValue>\n\n# The Autopsy\n\nWhen we look at the timeline of changes for FrameLoader::loadInSameDocument it seems that the bug was re-introduced in December 2016 due to refactoring. The question is, why did the patch author think that loadInSameDocument would not need to hold a reference. From the [December 2016 commit ChangeLog](<https://github.com/WebKit/WebKit/commit/aa31b6b4d09b09acdf1cec11f2f7f35bd362dd0e>): Take a raw pointer for the serialized script value state object. No one was passing ownership.\n\nMy assessment is that it\u2019s due to the October 2016 changes in HistoryItem:stateObject. When the author was evaluating the refactoring changes needed in the dom directory in December 2016, it would have appeared that the only calls to loadInSameDocument passed in either a null value or the result of stateObject() which as of October 2016 now passed a raw SerializedScriptValue* pointer. When looking at those two options for the type of an argument, then it\u2019s potentially understandable that the developer thought that loadInSameDocument did not need to share ownership of stateObject.\n\nSo why then was HistoryItem::stateObject\u2019s return value changed from a RefPtr to a raw pointer in October 2016? That I\u2019m struggling to find an explanation for. \n\nAccording to the description, the patch in October 2016 was intended to \u201cReplace all uses of ExceptionCodeWithMessage with WebCore::Exception\u201d. However when we look at the ChangeLog it seems that the author decided to also do some (seemingly unrelated) refactoring to HistoryItem. These are some of the only changes in the commit whose descriptions aren\u2019t related to exceptions. As an outsider looking at the commits, it seems that the developer by chance thought they\u2019d do a little \u201cclean-up\u201d while working through the required refactoring on the exceptions. If this was simply an additional ad-hoc step while in the code, rather than the goal of the commit, it seems plausible that the developer and reviewers may not have further traced the full lifetime of HistoryItem::stateObject.\n\nWhile the change to HistoryItem in October 2016 was not sufficient to introduce the bug, it seems that that change likely contributed to the developer in December 2016 thinking that loadInSameDocument didn\u2019t need to increase the reference count on the stateObject.\n\nBoth the October 2016 and the December 2016 commits were very large. The commit in October changed 40 files with 900 additions and 1225 deletions. The commit in December changed 95 files with 1336 additions and 1325 deletions. It seems untenable for any developers or reviewers to understand the security implications of each change in those commits in detail, especially since they\u2019re related to lifetime semantics.\n\n# The Zombie\n\nWe\u2019ve now tracked down the evolution of changes to fix the 2013 vulnerability\u2026and then revert those fixes\u2026 so I got back to identifying the 2022 bug. It\u2019s the same bug, but triggered through a different path. That\u2019s why the 2013 test case wasn\u2019t crashing the version of WebKit that should have been vulnerable to CVE-2022-22620:\n\n 1. The 2013 test case triggers the bug through the V8History::stateAccessorAndGetter path instead of FrameLoader::loadInSameDocument, and\n 2. As a part of Sergei\u2019s 2013 bug report there were additional hardening measures put into place that prevented user-code callbacks being processed during deserialization.\n\nTherefore we needed to figure out how to call loadInSameDocument and instead of using the deserialization to trigger a JavaScript callback, we needed to find another event in the loadInSameDocument function that would trigger the callback to user JavaScript.\n\nTo quickly figure out how to call loadInSameDocument, I modified the WebKit source code to trigger a test failure if loadInSameDocument was ever called and then ran all the tests in the fast/history directory. There were 5 out of the 80 tests that called loadInSameDocument:\n\n * [fast/history/multiple-back-forward-navigations.html](<https://github.com/WebKit/WebKit/blob/main/LayoutTests/fast/history/multiple-back-forward-navigations.html>)\n * [fast/history/history-traversal-is-asynchronous.html](<https://github.com/WebKit/WebKit/blob/main/LayoutTests/fast/history/history-traversal-is-asynchronous.html>)\n * [fast/history/history-back-forward-within-subframe-hash.html](<https://github.com/WebKit/WebKit/blob/main/LayoutTests/fast/history/history-back-forward-within-subframe-hash.html>)\n * [fast/history/link-inside-any.html](<https://github.com/WebKit/WebKit/blob/main/LayoutTests/fast/history/link-inside-any.html>)\n * [fast/history/timed-refresh-in-cached-frame.html](<https://github.com/WebKit/WebKit/blob/main/LayoutTests/fast/history/timed-refresh-in-cached-frame.html>)\n\nThe tests history-back-forward-within-subframe-hash.html and fast/history/history-traversal-is-asynchronous.html were the most helpful. We can trigger the call to loadInSameDocument by setting the history stack with an object whose location is the same page, but includes a hash. We then call history.back() to go back to that state that includes the URL with the hash. loadInSamePage is responsible for scrolling to that location.\n\nhistory.pushState(\"state1\", \"\", location + \"#foo\");\n\nhistory.pushState(\"state2\", \"\"); // current state\n\nhistory.back(); //goes back to state1, triggering loadInSameDocument \n \n--- \n \nNow that I knew how to call loadInSameDocument, I teamed up with Sergei to identify how we could get user code execution sometime during the loadInSameDocument function, but prior to the call to statePopped ([FrameLoader.cpp#1158](<https://github.com/WebKit/WebKit/blob/7b23cae2a1b1ffd026288f15261f8ba272c3b24b/Source/WebCore/loader/FrameLoader.cpp#L1158>)):\n\nm_frame.document()->statePopped(stateObject ? Ref<SerializedScriptValue> { *stateObject } : SerializedScriptValue::nullValue()); \n \n--- \n \nThe callback to user code would have to occur prior to the call to statePopped because stateObject was cast to a reference there and thus would now be reference-counted. We assumed that this would be the place where the \u201cfreed\u201d object was \u201cused\u201d.\n\nIf you go down the rabbit hole of the calls made in loadInSameDocument, we find that there is a path to the blur event being dispatched. We could have also used a tool like [CodeQL](<https://codeql.github.com/>) to see if there was a path from loadInSameDocument to dispatchEvent, but in this case we just used manual auditing. The call tree to the blur event is:\n\nFrameLoader::loadInSameDocument\n\nFrameLoader::scrollToFragmentWithParentBoundary\n\nFrameView::scrollToFragment\n\nFrameView::scrollToFragmentInternal\n\nFocusController::setFocusedElement\n\nFocusController::setFocusedFrame\n\ndispatchWindowEvent(Event::create(eventNames().blurEvent, Event::CanBubble::No, Event::IsCancelable::No)); \n \n--- \n \nThe blur event fires on an element whenever focus is moved from that element to another element. In our case loadInSameDocument is triggered when we need to scroll to a new location within the current page. If we\u2019re scrolling and therefore changing focus to a new element, the blur event is fired on the element that previously had the focus. \n\nThe last piece for our trigger is to free the stateObject in the onblur event handler. To do that we call replaceState, which overwrites the current history state with a new object. This causes the final reference to be dropped on the stateObject and it\u2019s therefore free\u2019d. loadInSameDocument still uses the free\u2019d stateObject in its call to statePopped.\n\ninput = document.body.appendChild(document.createElement(\"input\"));\n\na = document.body.appendChild(document.createElement(\"a\"));\n\na.id = \"foo\";\n\nhistory.pushState(\"state1\", \"\", location + \"#foo\");\n\nhistory.pushState(\"state2\", \"\");\n\nsetTimeout(() => {\n\ninput.focus();\n\ninput.onblur = () => history.replaceState(\"state3\", \"\");\n\nsetTimeout(() => history.back(), 1000);\n\n}, 1000); \n \n--- \n \nIn both the 2013 and 2022 cases, the root vulnerability is that the stateObject is not correctly reference-counted. In 2013, the developers did a great job of patching all the different paths to trigger the vulnerability, not just the one in the submitted proof-of-concept. This meant that they had also killed the vulnerability in loadInSameDocument. The refactoring in December 2016 then revived the vulnerability to enable it to be exploited in-the-wild and re-patched in 2022.\n\n# Conclusion\n\nUsually when we talk about variants, they exist due to incomplete patches: the vendor doesn\u2019t correctly and completely fix the reported vulnerability. However, for CVE-2022-22620 the vulnerability was correctly and completely fixed in 2013. Its fix was just regressed in 2016 during refactoring. We don\u2019t know how long an attacker was exploiting this vulnerability in-the-wild, but we do know that the vulnerability existed (again) for 5 years: December 2016 until January 2022.\n\nThere\u2019s no easy answer for what should have been done differently. The developers responding to the initial bug report in 2013 followed a lot of best-practices: \n\n * Patched all paths to trigger the vulnerability, not just the one in the proof-of-concept. This meant that they patched the variant that would become CVE-2022-22620.\n * Submitted a test case with the patch.\n * Detailed commit messages explaining the vulnerability and how they were fixing it.\n * Additional hardening measures during deserialization.\n\nAs an offensive security research team, we can make assumptions about what we believe to be the core challenges facing modern software development teams: legacy code, short reviewer turn-around expectations, refactoring and security efforts are generally under-appreciated and under-rewarded, and lack of memory safety mitigations. Developers and security teams need time to review patches, especially for security issues, and rewarding these efforts, will make a difference. It also will save the vendor resources in the long run. In this case, 9 years after a vulnerability was initially triaged, patched, tested, and released, the whole process had to be duplicated again, but this time under the pressure of in-the-wild exploitation. \n\nWhile this case study was a 0-day in Safari/WebKit, this is not an issue unique to Safari. Already in 2022, we\u2019ve seen in-the-wild 0-days that are variants of previously disclosed bugs targeting Chromium, Windows, Pixel, and iOS as well. It\u2019s a good reminder that as defenders we all need to stay vigilant in reviewing and auditing code and patches. \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": "2022-06-14T00:00:00", "type": "googleprojectzero", "title": "\nAn Autopsy on a Zombie In-the-Wild 0-day\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-2022-22600", "CVE-2022-22620"], "modified": "2022-06-14T00:00:00", "id": "GOOGLEPROJECTZERO:A395083F123D276DEBD13E65116FEA09", "href": "https://googleprojectzero.blogspot.com/2022/06/an-autopsy-on-zombie-in-wild-0-day.html", "cvss": {"score": 6.8, "vector": "AV:N/AC:M/Au:N/C:P/I:P/A:P"}}, {"lastseen": "2023-08-12T02:03:44", "description": "Posted by Maddie Stone, Google Project Zero\n\nThis blog post is an overview of a talk, \u201c 0-day In-the-Wild Exploitation in 2022\u2026so far\u201d, that I gave at the FIRST conference in June 2022. The slides are available [here](<https://github.com/maddiestone/ConPresentations/blob/master/FIRST2022.2022_0days_so_far.pdf>).\n\nFor the last three years, we\u2019ve published annual year-in-review reports of 0-days found exploited in the wild. The most recent of these reports is the [2021 Year in Review report](<https://googleprojectzero.blogspot.com/2022/04/the-more-you-know-more-you-know-you.html>), which we published just a few months ago in April. While we plan to stick with that annual cadence, we\u2019re publishing a little bonus report today looking at the in-the-wild 0-days detected and disclosed in the first half of 2022. \n\nAs of June 15, 2022, there have been 18 0-days detected and disclosed as exploited in-the-wild in 2022. When we analyzed those 0-days, we found that at least nine of the 0-days are variants of previously patched vulnerabilities. At least half of the 0-days we\u2019ve seen in the first six months of 2022 could have been prevented with more comprehensive patching and regression tests. On top of that, four of the 2022 0-days are variants of 2021 in-the-wild 0-days. Just 12 months from the original in-the-wild 0-day being patched, attackers came back with a variant of the original bug. \n\nProduct\n\n| \n\n2022 ITW 0-day\n\n| \n\nVariant \n \n---|---|--- \n \nWindows win32k\n\n| \n\n[CVE-2022-21882](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2022/CVE-2022-21882.html>)\n\n| \n\n[CVE-2021-1732](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-1732.html>) (2021 itw) \n \niOS IOMobileFrameBuffer\n\n| \n\n[CVE-2022-22587](<https://support.apple.com/en-us/HT213053>)\n\n| \n\n[CVE-2021-30983](<https://googleprojectzero.blogspot.com/2022/06/curious-case-carrier-app.html>) (2021 itw) \n \nWindows\n\n| \n\n[CVE-2022-30190](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30190>) (\u201cFollina\u201d)\n\n| \n\n[CVE-2021-40444](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-40444>) (2021 itw) \n \nChromium property access interceptors\n\n| \n\n[CVE-2022-1096](<https://chromereleases.googleblog.com/2022/03/stable-channel-update-for-desktop_25.html>)\n\n| \n\n[CVE-2016-5128](<https://bugs.chromium.org/p/chromium/issues/detail?id=619166>) [CVE-2021-30551](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2021/CVE-2021-30551.html>) (2021 itw) [CVE-2022-1232](<https://bugs.chromium.org/p/project-zero/issues/detail?id=2280>) (Addresses incomplete CVE-2022-1096 fix) \n \nChromium v8\n\n| \n\n[CVE-2022-1364](<https://chromereleases.googleblog.com/2022/04/stable-channel-update-for-desktop_14.html>)\n\n| \n\n[CVE-2021-21195](<https://chromereleases.googleblog.com/2021/03/stable-channel-update-for-desktop_30.html>) \n \nWebKit\n\n| \n\n[CVE-2022-22620](<https://googleprojectzero.github.io/0days-in-the-wild//0day-RCAs/2022/CVE-2022-22620.html>) (\u201cZombie\u201d)\n\n| \n\n[Bug was originally fixed in 2013, patch was regressed in 2016](<https://googleprojectzero.blogspot.com/2022/06/an-autopsy-on-zombie-in-wild-0-day.html>) \n \nGoogle Pixel\n\n| \n\n[CVE-2021-39793](<https://source.android.com/security/bulletin/pixel/2022-03-01>)*\n\n* While this CVE says 2021, the bug was patched and disclosed in 2022\n\n| \n\n[Linux same bug in a different subsystem](<https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cd5297b0855f17c8b4e3ef1d20c6a3656209c7b3>) \n \nAtlassian Confluence\n\n| \n\n[CVE-2022-26134](<https://confluence.atlassian.com/doc/confluence-security-advisory-2022-06-02-1130377146.html>)\n\n| \n\n[CVE-2021-26084](<https://confluence.atlassian.com/doc/confluence-security-advisory-2021-08-25-1077906215.html>) \n \nWindows\n\n| \n\n[CVE-2022-26925](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-26925>) (\u201cPetitPotam\u201d)\n\n| \n\n[CVE-2021-36942](<https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-36942>) (Patch regressed) \n \nSo, what does this mean?\n\nWhen people think of 0-day exploits, they often think that these exploits are so technologically advanced that there\u2019s no hope to catch and prevent them. The data paints a different picture. At least half of the 0-days we\u2019ve seen so far this year are closely related to bugs we\u2019ve seen before. Our conclusion and findings in the [2020 year-in-review report](<https://googleprojectzero.blogspot.com/2021/02/deja-vu-lnerability.html>) were very similar.\n\nMany of the 2022 in-the-wild 0-days are due to the previous vulnerability not being fully patched. In the case of the Windows win32k and the Chromium property access interceptor bugs, the execution flow that the proof-of-concept exploits took were patched, but the root cause issue was not addressed: attackers were able to come back and trigger the original vulnerability through a different path. And in the case of the WebKit and Windows PetitPotam issues, the original vulnerability had previously been patched, but at some point regressed so that attackers could exploit the same vulnerability again. In the iOS IOMobileFrameBuffer bug, a buffer overflow was addressed by checking that a size was less than a certain number, but it didn\u2019t check a minimum bound on that size. For more detailed explanations of three of the 0-days and how they relate to their variants, please see the [slides from the talk](<https://github.com/maddiestone/ConPresentations/blob/master/FIRST2022.2022_0days_so_far.pdf>).\n\nWhen 0-day exploits are detected in-the-wild, it\u2019s the failure case for an attacker. It\u2019s a gift for us security defenders to learn as much as we can and take actions to ensure that that vector can\u2019t be used again. The goal is to force attackers to start from scratch each time we detect one of their exploits: they\u2019re forced to discover a whole new vulnerability, they have to invest the time in learning and analyzing a new attack surface, they must develop a brand new exploitation method. To do that effectively, we need correct and comprehensive fixes.\n\nThis is not to minimize the challenges faced by security teams responsible for responding to vulnerability reports. As we said in our 2020 year in review report: \n\nBeing able to correctly and comprehensively patch isn't just flicking a switch: it requires investment, prioritization, and planning. It also requires developing a patching process that balances both protecting users quickly and ensuring it is comprehensive, which can at times be in tension. While we expect that none of this will come as a surprise to security teams in an organization, this analysis is a good reminder that there is still more work to be done. \n\nExactly what investments are likely required depends on each unique situation, but we see some common themes around staffing/resourcing, incentive structures, process maturity, automation/testing, release cadence, and partnerships.\n\nPractically, some of the following efforts can help ensure bugs are correctly and comprehensively fixed. Project Zero plans to continue to help with the following efforts, but we hope and encourage platform security teams and other independent security researchers to invest in these types of analyses as well:\n\n * Root cause analysis\n\nUnderstanding the underlying vulnerability that is being exploited. Also tries to understand how that vulnerability may have been introduced. Performing a root cause analysis can help ensure that a fix is addressing the underlying vulnerability and not just breaking the proof-of-concept. Root cause analysis is generally a pre-requisite for successful variant and patch analysis.\n\n * Variant analysis\n\nLooking for other vulnerabilities similar to the reported vulnerability. This can involve looking for the same bug pattern elsewhere, more thoroughly auditing the component that contained the vulnerability, modifying fuzzers to understand why they didn\u2019t find the vulnerability previously, etc. Most researchers find more than one vulnerability at the same time. By finding and fixing the related variants, attackers are not able to simply \u201cplug and play\u201d with a new vulnerability once the original is patched.\n\n * Patch analysis\n\nAnalyzing the proposed (or released) patch for completeness compared to the root cause vulnerability. I encourage vendors to share how they plan to address the vulnerability with the vulnerability reporter early so the reporter can analyze whether the patch comprehensively addresses the root cause of the vulnerability, alongside the vendor\u2019s own internal analysis.\n\n * Exploit technique analysis\n\nUnderstanding the primitive gained from the vulnerability and how it\u2019s being used. While it\u2019s generally industry-standard to patch vulnerabilities, mitigating exploit techniques doesn\u2019t happen as frequently. While not every exploit technique will always be able to be mitigated, the hope is that it will become the default rather than the exception. Exploit samples will need to be shared more readily in order for vendors and security researchers to be able to perform exploit technique analysis.\n\nTransparently sharing these analyses helps the industry as a whole as well. We publish our analyses at [this repository](<https://googleprojectzero.github.io/0days-in-the-wild/rca.html>). We encourage vendors and others to publish theirs as well. This allows developers and security professionals to better understand what the attackers already know about these bugs, which hopefully leads to even better solutions and security overall. \n", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-06-30T00:00:00", "type": "googleprojectzero", "title": "\n2022 0-day In-the-Wild Exploitation\u2026so far\n", "bulletinFamily": "info", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2016-5128", "CVE-2021-1732", "CVE-2021-21195", "CVE-2021-26084", "CVE-2021-30551", "CVE-2021-30983", "CVE-2021-36942", "CVE-2021-39793", "CVE-2021-40444", "CVE-2022-1096", "CVE-2022-1232", "CVE-2022-1364", "CVE-2022-21882", "CVE-2022-22587", "CVE-2022-22620", "CVE-2022-26134", "CVE-2022-26925", "CVE-2022-30190"], "modified": "2022-06-30T00:00:00", "id": "GOOGLEPROJECTZERO:3B4F7E79DDCD0AFF3B9BB86429182DCA", "href": "https://googleprojectzero.blogspot.com/2022/06/2022-0-day-in-wild-exploitationso-far.html", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}], "osv": [{"lastseen": "2023-06-28T06:52:27", "description": "\nThe following vulnerabilities have been discovered in the WPE WebKit\nweb engine:\n\n\n* [CVE-2022-22589](https://security-tracker.debian.org/tracker/CVE-2022-22589)\nHeige and Bo Qu discovered that processing a maliciously crafted\n mail message may lead to running arbitrary javascript.\n* [CVE-2022-22590](https://security-tracker.debian.org/tracker/CVE-2022-22590)\nToan Pham discovered that processing maliciously crafted web\n content may lead to arbitrary code execution.\n* [CVE-2022-22592](https://security-tracker.debian.org/tracker/CVE-2022-22592)\nPrakash discovered that processing maliciously crafted web content\n may prevent Content Security Policy from being enforced.\n* [CVE-2022-22620](https://security-tracker.debian.org/tracker/CVE-2022-22620)\nAn anonymous researcher discovered that processing maliciously\n crafted web content may lead to arbitrary code execution.

The flaw also can lead to unexpected OS crashes.\n\n\u201cApple is aware of a report that this issue may have been actively exploited,\u201d the company wrote in its update notes.\n\nThe simplest way threat actors can exploit the flaw involves the system\u2019s reuse of freed memory, according to the vulnerability\u2019s description on the Common Weakness Enumeration website. \u201cReferencing memory after it has been freed can cause a program to crash, use unexpected values or execute code,\u201d according to the [post](<https://cwe.mitre.org/data/definitions/416.html>).\n\nExploiting previously freed memory can have various adverse consequences, \u201cranging from the corruption of valid data to the execution of arbitrary code, depending on the instantiation and timing of the flaw,\u201d the description said.\n\n## **Memory Error**\n\nThese types of errors typically have two common and sometimes overlapping causes: error conditions and other exceptional circumstances, and confusion over which part of the program is responsible for freeing the memory, according to the post.\n\nIn the case of CVE-2022-22620, the memory in question is allocated to another pointer validly at some point after it has been freed. The original pointer to the freed memory is used again and points to somewhere within the new allocation.\n\n\u201cAs the data is changed, it corrupts the validly used memory; this induces undefined behavior in the process,\u201d according to the post.\n\nIf the newly allocated data happens to hold a class \u2013 for example, in C++ code \u2013 various function pointers may be scattered within the heap data. \u201cIf one of these function pointers is overwritten with an address to valid shellcode, execution of arbitrary code can be achieved,\u201d Apple\u2019s post explained.\n\n## **Numerous Devices Affected**\n\nApple released separate security updates for its products to address the issue \u2013 [macOS Monterey 12.2.1](<https://support.apple.com/en-us/HT213092>), [iOS 15.3.1 and iPadOS 15.3.1](<https://support.apple.com/en-us/HT213093>). Both updates improve how the OSes manage memory.\n\nThe flaw affects numerous Apple devices, including iPhone 6s and later; all iPad Pro models, iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch 7th generation. It also affects desktops and notebooks running macOS Monterey.\n\nThe update is the second time this year that Apple has had to issue a patch for a zero day. [Last month](<https://threatpost.com/apple-zero-day-security-exploited/178040/>), the company also had to patch a memory issue \u2013 a zero-day flaw also affecting iOS, iPadOS and macOS Monterey tracked as [CVE-2022-22587](<https://packetstormsecurity.com/files/cve/CVE-2022-22587>). Attackers could exploit the bug using a malicious app to execute arbitrary code with kernel privileges.\n\nAt the same time, the company patched another WebKit zero-day tracked as [CVE-2022-22594](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-22594>). The information-disclosure issue affects browsers for macOS, iOS and iPadOS and allows a snooping website to find out information about other tabs a user might have open.\n\nLast year Apple also patched several zero-day vulnerabilities, including [a zero-click zero-day](<https://threatpost.com/apple-emergency-fix-nso-zero-click-zero-day/169416/>) exploited by the NSO Group\u2019s Pegasus spyware and [a memory-corruption flaw](<https://threatpost.com/apple-patches-actively-exploited-zero-day-in-ios-macos/168177/>) in its iOS and macOS platforms that could allow for system takeover.\n\n## How to Force an Update if Necessary\n\nAs is typical for Apple, it didn\u2019t disclose many details of the vulnerability and won\u2019t until the investigation is completed. At any rate, \u201cthe majority of users have the patches installed,\u201d pointed out Kaspersky in an early morning Friday [post](<https://www.kaspersky.com/blog/webkit-vulnerability-cve-2022-22620/43650/>).\u201dSimply put, the most likely attack scenario is an infection of an iPhone or iPad device after visiting a malicious web page,\u201d noted the security firm\u2019s post.\n\nInstalling the OS 15.3.1 and iPadOS 15.3.1 updates will protect your device, though it does need to be connected to a Wi-Fi network in order to install the patch.\n\nFor devices that aren\u2019t yet showing that the update is ready to be installed, Kaspersky advised that systems can be forced into updating faster by going to system settings (Settings \u2192 General \u2192 Software update) and checking the availability of software updates.\n\n_021122 09:25 update: Added content from Kaspersky\u2019s post._\n\n_**Join Threatpost on **Wed.
