Tracked as CVE-2021-30713, the zero-day concerns a permissions issue in Apple's Transparency, Consent, and Control ([TCC](<https://support.apple.com/en-in/guide/security/secddd1d86a6/web>)) framework in macOS that maintains a database of each user's consents. The iPhone maker acknowledged that the issue may have been exploited in the wild but stopped short of sharing specifics. The company noted that it rectified the problem with improved validation. However, in a separate report, mobile device management company Jamf said the bypass flaw was being actively exploited by XCSSET, a malware that's been out in the wild since August 2020 and known to propagate via modified [Xcode IDE projects](<https://developer.apple.com/library/archive/featuredarticles/XcodeConcepts/Concept-Projects.html>) hosted on GitHub repositories and plant malicious packages into legitimate apps installed on the target system. "The exploit in question could allow an attacker to gain Full Disk Access, Screen Recording, or other permissions without requiring the user's explicit consent — which is the default behavior," Jamf researchers Stuart Ashenbrenner, Jaron Bradley, and Ferdous Saljooki [said](<https://www.jamf.com/blog/zero-day-tcc-bypass-discovered-in-xcsset-malware/>) in a write-up.

Specifically, the malware checked for screen capture permissions from a list of installed applications, such as Zoom, Discord, WhatsApp, Slack, TeamViewer, Upwork, Skype, and Parallels Desktop, to inject the malware ("avatarde.app") into the app's folder, thereby inheriting the necessary permissions required to carry out its nefarious tasks. "By leveraging an installed application with the proper permissions set, the attacker can piggyback off that donor app when creating a malicious app to execute on victim devices, without prompting for user approval," the researchers noted. XCSSET was also the subject of closer scrutiny [last month](<https://thehackernews.com/2021/04/malware-spreads-via-xcode-projects-now.html>) after a new variant of the malware was detected targeting Macs running on Apple's new M1 chips to steal wallet information from cryptocurrency apps. One of its primary functions is to siphon Safari browser cookies as well as install a developer version of the Safari application to load JavaScript backdoors from its command-and-control server. Also fixed as part of Monday's updates are two other actively exploited flaws in its WebKit browser engine affecting Safari, Apple TV 4K, and Apple TV HD devices, almost three weeks after Apple addressed the same issues in [iOS, macOS, and watchOS](<https://thehackernews.com/2021/05/apple-releases-urgent-security-patches.html>) earlier this month. * **CVE-2021-30663** \- An integer overflow issue in WebKit, which could be exploited to achieve arbitrary code execution when processing maliciously crafted web content. * **CVE-2021-30665** \- A memory corruption issue in WebKit that could lead to arbitrary code execution when processing maliciously crafted web content. Users of Apple devices are recommended to update to the latest versions to mitigate the risk associated with the flaws. Found this article interesting?

A summary of the three security bugs are as follows -\n\n * **CVE-2021-30663:** An integer overflow vulnerability that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addressed with improved input validation.\n * **CVE-2021-30665:** A memory corruption issue that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addressed with improved state management.\n * **CVE-2021-30666:** A buffer overflow vulnerability that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addressed with improved memory handling.\n\nThe development comes a week after Apple rolled out iOS 14.5 and macOS Big Sur 11.3 with a fix for a potentially exploited WebKit Storage vulnerability. Tracked as [CVE-2021-30661](<https://thehackernews.com/2021/04/hackers-exploit-0-day-gatekeeper-flaw.html>), the use-after-free issue was discovered and reported to the iPhone maker by a security researcher named yangkang ([@dnpushme](<https://twitter.com/dnpushme>)) of Qihoo 360 ATA.\n\nyangkang, along with zerokeeper and bianliang, have been credited with reporting the three new flaws.\n\nIt's worth noting that CVE-2021-30666 only affects older Apple devices such as iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation). The [iOS 12.5.3](<https://support.apple.com/en-us/HT212341>) update, which remediates this flaw, also includes a fix for CVE-2021-30661.\n\nThe company said it's aware of reports that the issues \"may have been actively exploited\" but, as is typically the case, failed to elaborate about the nature of attacks, the victims that may have been targeted, or the threat actors that may be abusing them.\n\nUsers of Apple devices are recommended to update to the latest versions to mitigate the risk associated with the flaws.\n\n**Update: **Apple has also [released](<https://support.apple.com/en-us/HT212340>) a new version of Safari 14.1 for macOS Catalina and macOS Mojave, with the update introducing fixes for the two WebKit flaws CVE-2021-30663 and CVE-2021-30665. The update comes a day after patches were shipped for iOS, macOS, and watchOS.\n\n \n\n\nFound this article interesting?

The flaw was addressed with improved state management.\n * **CVE-2021-30762** \\- A use-after-free issue that could be exploited to gain arbitrary code execution when processing maliciously crafted web content. The flaw was resolved with improved memory management.\n\nBoth CVE-2021-30761 and CVE-2021-30762 were reported to Apple anonymously, with the Cupertino-based company stating in its advisory that it's aware of reports that the vulnerabilities \"may have been actively exploited.\" As is usually the case, Apple didn't share any specifics on the nature of the attacks, the victims that may have been targeted, or the threat actors that may be abusing them.\n\nOne thing evident, however, is that the active exploitation attempts were directed against owners of older devices such as iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation).

The [Security & Privacy pane](<https://support.apple.com/en-ie/guide/mac-help/mchlf6d108da/mac>) in the macOS System Preferences app serves as the front end of TCC.\n\nMicrosoft 365 Defender Research Team, which reported the vulnerability to Apple on July 15, 2021, dubbed the flaw \"**powerdir**.\" Apple [addressed](<https://thehackernews.com/2021/12/latest-apple-ios-update-patches-remote.html>) the issue as part of macOS 11.6 and 12.1 updates released in December 2021 with improved state management.\n\nWhile Apple does enforce a policy that limits access to TCC to only apps with full disk access, it's possible to orchestrate an attack wherein a malicious application could work around its privacy preferences to retrieve sensitive information from the machine, potentially allowing an adversary to access microphone to record private conversations or capture screenshots of sensitive information displayed on the user's screen.\n\n\"We discovered that it is possible to programmatically change a target user's home directory and plant a fake TCC database, which stores the consent history of app requests,\" Jonathan Bar Or of Microsoft 365 Defender Research Team [said](<https://www.microsoft.com/security/blog/2022/01/10/new-macos-vulnerability-powerdir-could-lead-to-unauthorized-user-data-access/>). \"If exploited on unpatched systems, this vulnerability could allow a malicious actor to potentially orchestrate an attack based on the user's protected personal data.\"\n\n[![macOS](https://thehackernews.com/new-images/img/a/AVvXsEjjfrgh7suOG5Tu2OGmCDL7fyu4WfgKMb-41CAK5oVT_r8YkC1OxocnbLVKGEN1N24pionza2DTyKbVadGoPG7nBHPgFZvuCZ-gD26vnf4WVavho3uad8zAnuFIke65TKWKW9KB3FwHSzPyTNCJ7rQh374j0-pljst9_rUfwXMJsqlkC7KkcXuYaALf=s728-e1000)](<https://thehackernews.com/new-images/img/a/AVvXsEjjfrgh7suOG5Tu2OGmCDL7fyu4WfgKMb-41CAK5oVT_r8YkC1OxocnbLVKGEN1N24pionza2DTyKbVadGoPG7nBHPgFZvuCZ-gD26vnf4WVavho3uad8zAnuFIke65TKWKW9KB3FwHSzPyTNCJ7rQh374j0-pljst9_rUfwXMJsqlkC7KkcXuYaALf>)\n\nIn other words, if a bad actor gains full disk access to the TCC databases, the intruder could edit it to grant arbitrary permissions to any app of their choice, including their own, effectively permitting the app run with configurations previously not consented to.\n\nCVE-2021-30970 is also the third TCC-related bypass vulnerability to be discovered after [CVE-2020-9934](<https://nvd.nist.gov/vuln/detail/CVE-2020-9934>) and [CVE-2020-27937](<https://nvd.nist.gov/vuln/detail/CVE-2020-27937>), both of which have since been remediated by Apple. Then in May 2021, the company also patched a then zero-day flaw in the same component ([CVE-2021-30713](<https://thehackernews.com/2021/05/apple-issues-patches-to-combat-ongoing.html>)) that could allow an attacker to gain full disk access, screen recording, or other permissions without users' explicit consent.\n\n\"This shows that even as macOS or other operating systems and applications become more hardened with each release, software vendors like Apple, security researchers, and the larger security community, need to continuously work together to identify and fix vulnerabilities before attackers can take advantage of them,\" Bar Or said.\n\n \n\n\nFound this article interesting?

Apple so far has not provided specific details about the vulnerability in its entry in the CVE database.\n\nThe flaw works by bypassing the Transparency Consent and Control (TCC) framework, which controls what resources applications have access to, \u201csuch as granting video collaboration software access to the webcam and microphone, in order to participate in virtual meetings,\u201d according to the Jamf post.\n\n\u201cThe exploit in question could allow an attacker to gain Full Disk Access, Screen Recording, or other permissions without requiring the user\u2019s explicit consent\u2013which is the default behavior,\u201d researchers said.\n\n## **History of a Spyware**\n\nTrend Micro discovered the XCSSET malware [last August](<https://threatpost.com/mac-spyware-xcode-projects/158388/>) when researchers noticed cybercriminals injecting malware into Xcode developer projects, resulting in a propagation of infections. They identified the malware as a suite called XCSSET, which can hijack the Safari web browser and inject various JavaScript payloads that can steal passwords, financial data and personal information, deploy ransomware, and perform other malicious functions.\n\nAt the time Trend Micro researchers noticed XCSSET using two zero-day flaws to do its dirty work\u2014one in Data Vault that allowed it to bypass macOS\u2019 System Integrity Protection (SIP) feature; and one in Safari for WebKit Development that allowed universal cross-site scripting (UXSS).\n\nNow it appears a third zero-day flaw can be added to the list of those XCSSET can exploit, according to Jamf, which described in detail how the spyware takes advantage of the bug to bypass the TCC.\n\nUpon a deep dive into the spyware, the Jamf Protect detection team members noticed an AppleScript module titled \u201cscreen_sim.applescript\u201d with a check called \u201cverifyCapturePermissions\u201d being used to search for an app with permissions to capture a screenshot from a list of installed apps. The list was derived from an earlier check of the following software appID\u2019s, referred to by the malware as \u201cdonorApps.\u201d\n\n\u201cAs expected, the list of application IDs that are targeted are all applications that users regularly grant the screen-sharing permission to as part of its normal operation,\u201d researchers wrote. \u201cThe malware then uses the following mdfind command\u2013the command-line-based version of Spotlight\u2013to check if the appID\u2019s are installed on the victim\u2019s device.\u201d\n\nIf any of those IDs are found on the system, the command returns the path to the installed application and, with this information, XCSSET crafts a custom AppleScript application and injects it into the installed, donor application.\n\nFor example, if the virtual meeting app Zoom (zoom.us.app) is found on the system, the malware will place itself like this: /Applications/zoom.us.app/Contents/MacOS/avatarde.app. If the victim machine is running macOS11 or greater, it will then sign the avatarde application with an ad-hoc signature, or one that is signed by the computer itself, researchers said.\n\nXCSSET can then take screenshots or record the screen when the victim is using Zoom without needing explicit consent from the user, inheriting those TCC permissions outright from the Zoom parent app. Researchers found that XCSSET also can use the flaw to hijack other permissions beyond screensharing as well.\n\n## **MacOS Threats on the Rise**\n\nApple\u2019s latest security woe comes on the heels of an Apple exec publicly lamenting the level of malware against the Mac platform, calling it [\u201cunacceptable\u201d](<https://threatpost.com/apple-mac-malware-unacceptable/166340/>) in testimony in a California court last Wednesday for a [lawsuit](<https://cand.uscourts.gov/wp-content/uploads/cases-of-interest/epic-games-v-apple/20-5640_Epic_Games_Dkt_48_Order_Granting_in_Part_and_Denying_in_Part_Motion_for_a_Temporary_Restraining_Order.pdf>) (PDF) brought against the company by Epic Games, maker of Fortnite.\n\nApple head of software engineering Craig Federighi used the threat level as an excuse for Apple\u2019s tight restrictions on the software that is allowed to run on its platform and sell within its iOS App Store.\n\nIndeed, 2021 has been a less-than stellar year so far for Apple security. Earlier this month, Apple [released a quartet](<https://threatpost.com/apple-zero%E2%80%91days-active-attack/165842/>) of unscheduled updates for iOS, macOS, and watchOS, to slap security patches on flaws in its WebKit browser engine.\n\nA week before that, Apple [patched a zero-day vulnerability](<https://threatpost.com/apple-patches-macos-bug-bypass-defenses/165611/>) in its MacOS that can bypass critical anti-malware capabilities and which a variant of the notorious Mac threat Shlayer adware dropper already had been exploiting for several months.\n\nThe company kicked off the year by removing a contentious macOS feature that allowed some Apple apps to bypass content filters, VPNs and third-party firewalls.

Here\u2019s a summary of the three zero-days: \n\n## **Zero-Day Bugs in WebKit**\n\n * **CVE-2021-30665:** A critical memory-corruption issue in the Safari WebKit engine where \u201cprocessing maliciously crafted web content may lead to arbitrary code execution\u201d was addressed with improved state management. Available for: 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). The bug was reported to Apple by three security researchers, nicknamed yangkang, zerokeeper and bianliang. \n\n * **CVE-2021-30663:** This second flaw is also found in the open-source WebKit browser engine. It\u2019s an integer overflow, reported by an anonymous researcher, that can also lead to RCE. It was addressed with improved input validation. Available for: 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\n * **CVE-2021-30666:** A buffer-overflow issue was addressed with improved memory handling. Available for: iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation)\n\nAnd here are details on the expanded patch for the fourth bug: \n\n## **WebKit Storage**\n\n * **CVE-2021-30661: **A use after free issue was addressed with improved memory management. Available for: iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation). This flaw was discovered and reported to the iPhone maker by the security researcher named yangkang, @dnpushme, of Qihoo 360 ATA.\n\nApple\u2019s support page shows that this fourth one was actually patched on Monday last week (April 26) in iOS 14.5 and macOS 11.3, but not in iOS 12. \n\nNaked Security\u2019s Paul Ducklin finds this one [particularly interesting](<https://nakedsecurity.sophos.com/2021/05/04/apple-products-hit-by-fourfecta-of-zero-day-exploits-patch-now/>), and he noted that questions remain. Why wasn\u2019t iOS 12 updated at the same time as iOS 14.5 and macOS 11.3? Did the security hole crop up in the code base after iOS 12 was released, perhaps? \n\nNo, that\u2019s not it: the CVE-2021-30661 and CVE-2021-30666 bugs fixed on Monday only apply to iOS 12. So it remains unclear if the bug exists in recent operating system versions, or not, Ducklin said.\n\n\u201cIs this an old bug from iOS 12 that was carried forward into the current Apple codebase but has still not yet been patched there?\u201d Ducklin pondered. \u201cOr is it a bug that is unique to the older iOS 12 code that doesn\u2019t appear in the more recent operating system releases and can therefore now be considered to have been eliminated everywhere?\u201d\n\nThreatpost has reached out to Apple for comment.\n\n## **Patch Fast!**\n\nPer usual, Apple\u2019s lip is zipped. But one thing\u2019s for sure: Patching as soon as possible is top priority. As it is, the chance for websites passing along \u201cmaliciously crafted web content\u201d is alarming. If you translate Apple\u2019s statement that \u201cprocessing maliciously crafted web content may lead to arbitrary code execution, \u201cyou get a \u201c[drive-by](<https://threatpost.com/google-sites-solarmarket-rat/165396/>), web-based zero-day RCE exploit, according to Ducklin.\n\nIn other words, all you have to do to trigger infection is to visit and view a booby-trapped website. \n\nJohn Kinsella, chief architect at cloud security company Accurics, says this is one of the nastier types of security bugs: one in which the user isn\u2019t required to perform a certain action for an attacker\u2019s success. \u201cPart of the issue here is that it\u2019s not just the browser that a user needs to be careful with,\u201d he told Threatpost in an email on Tuesday. \u201cMany iOS apps are just wrappers around a web application, which would be rendered by WebKit. For example, HTML mail in Apple\u2019s Mail app will be rendered by WebKit, and this app is a hard one to avoid. Even if a user takes advantage of new iOS functionality to replace the default iOS Mail and Safari apps with other mail/browser apps, the underlying HTML rendering engine would still be WebKit-based on Apple\u2019s App Store rules.\u201d\n\nKinsella says that if he\u2019s at all suspicious of something, he won\u2019t open it on a mobile device, but rather on a desktop or laptop, where he has much more control. \u201cThat being said, I know I\u2019m not the average user,\u201d he said. \u201cThe best advice I have is to patch ASAP, and generally be very careful.\u201d\n\nGiven that Apple has acknowledged that these vulnerabilities have already been exploited in the wild, and given the fact that HTML content is so prevalent on mobile devices, Kinsella considers a drive-by RCE like this to be a highly serious issue, though \u201cThe overall security of iOS means this isn\u2019t a complete takeover of the mobile device.\u201d\n\nStill, every extra foothold an attacker can get \u201chelps them further compromise a device,\u201d he said. \u201cThe fact that malicious HTML can compromise something on my wrist doesn\u2019t thrill me. Luckily Apple\u2019s been quite consistent with the reliability of their patches in recent years, so while I may sometimes wait for others to \u2018beta test\u2019 a release, a security patch like this was applied to my devices ASAP.\u201d\n\n## **What is WebKit? The Little Engine That Could**\n\nApple developed the WebKit browser engine to run in its Safari web browser, but it\u2019s also used by Apple Mail, the App Store, and various apps on the macOS and iOS operating systems. This, of course, isn\u2019t the first time that the engine has hit some bumps. \n\nIn January, Apple released an emergency update that patched three iOS[ bugs](<https://threatpost.com/apple-patches-zero-days-ios-emergency-update/163374/>). Two of them (CVE-2021-1870 and CVE-2021-1871 ) were discovered in WebKit (and the third, tracked as CVE-2021-1782, was found in the OS kernel).\n\nMore recently, in March, Apple patched other [severe WebKit RCEs](<https://threatpost.com/apple-webkit-remote-code-execution/164595/>). Similar to Monday\u2019s updates, those WebKit fixes could have allowed remote attackers to completely compromise affected systems.\n\n05-04-2021 14:52 UPDATE: Added input from Accurics\u2019 John Kinsella.\n\n**Join Threatpost for \u201c**[**Fortifying Your Business Against Ransomware, DDoS & Cryptojacking Attacks**](<https://threatpost.com/webinars/fortifying-your-business-against-attacks/?utm_source=ART&utm_medium=ART&utm_campaign=May_Zoho_Webinar>)**\u201d \u2013 a LIVE roundtable event on**[** Wed, May 12 at 2:00 PM EDT**](<https://threatpost.com/webinars/fortifying-your-business-against-attacks/?utm_source=ART&utm_medium=ART&utm_campaign=May_Zoho_Webinarhttps://threatpost.com/webinars/fortifying-your-business-against-attacks/?utm_source=ART&utm_medium=ART&utm_campaign=May_Zoho_Webinar>)**.

Specifically, it could allow an attacker to bypass the operating system\u2019s [Transparency, Consent and Control](<https://support.apple.com/guide/security/controlling-app-access-to-files-secddd1d86a6/web>) (TCC) technology, thereby gaining unauthorized access to a user\u2019s protected data, the Microsoft 365 Defender Research Team said in its [advisory](<https://www.microsoft.com/security/blog/2022/01/10/new-macos-vulnerability-powerdir-could-lead-to-unauthorized-user-data-access/>).\n\nIntroduced in 2012 in macOS Mountain Lion, TCC helps users to configure their apps\u2019 privacy settings by requiring that all apps get user consent before accessing files in Documents, Downloads, Desktop, iCloud Drive, calendar and network volumes, as well as before the apps are allowed to access the device\u2019s camera, microphone or location.\n\nApple released a fix for the vulnerability \u2013 identified as [CVE-2021-30970](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30970>) \u2013 in macOS Big Sur and macOS Monterey, as [part of](<https://threatpost.com/apple-ios-updates-iphone-13-jailbreak-exploit/177051/>) its Dec. 13, 2021 [security updates](<https://support.apple.com/en-us/HT212978>). At the time, as is typical, Apple didn\u2019t give much detail, merely stating that the flaw was a logic issue that could allow a malicious to bypass privacy preferences: A flaw that it addressed with improved state management.\n\n## The Bug Trips Up TCC\n\nTCC stores the consent history of app requests. The feature prevents unauthorized code execution by restricting full disk access to only those apps with appropriate privileges \u2013 at least, that\u2019s the way it\u2019s supposed to work.\n\nBut Microsoft researchers discovered that it\u2019s possible to programmatically change a target user\u2019s home directory and to plant a fake TCC database.\n\n\u201cIf exploited on unpatched systems, this vulnerability could allow a malicious actor to potentially orchestrate an attack based on the user\u2019s protected personal data,\u201d they explained in Monday\u2019s advisory. \u201cFor example, the attacker could hijack an app installed on the device \u2013 or install their own malicious app \u2013 and access the microphone to record private conversations or capture screenshots of sensitive information displayed on the user\u2019s screen.\u201d\n\nTypically, users manage TCC under System Preferences in macOS (System Preferences > Security & Privacy > Privacy).\n\n[![](https://media.threatpost.com/wp-content/uploads/sites/103/2022/01/11143551/security-privacy-pane-e1641929765781.png)](<https://media.threatpost.com/wp-content/uploads/sites/103/2022/01/11143551/security-privacy-pane-e1641929765781.png>)\n\nThe macOS Security & Privacy pane that serves as the front end of TCC. Source: Microsoft.\n\nAs Microsoft explained, when an app requests access to protected user data, one of two things can happen:\n\n 1. If the app and the type of request have a record in the TCC databases, then a flag in the database entry dictates whether to allow or deny the request \u2014 automatically and without any user interaction.\n 2. If the app and the type of request do not have a record in the TCC databases, then a prompt is presented to the user, who decides whether to grant or deny access. The said decision is backed into the databases so that succeeding similar requests will now fall under the first scenario.\n\nIf an attacker gets full disk access to the TCC databases, Microsoft explained that the world\u2019s then their app oyster: \u201cThey could edit it to grant arbitrary permissions to any app they choose, including their own malicious app. The affected user would also not be prompted to allow or deny the said permissions, thus allowing the app to run with configurations they may not have known or consented to.\u201d\n\n## Prior TCC Trespasses\n\nThis isn\u2019t the first time that TCC databases have shown themselves to be susceptible to bypass. Microsoft listed this trio of past vulnerabilities:\n\n * **Time Machine mounts** ([CVE-2020-9771](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-9771>)): macOS offers a built-in backup and restore solution called [Time Machine](<https://support.apple.com/en-us/HT201250>). It was discovered that Time Machine backups could be mounted (using the apfs_mount utility) with the \u201cnoowners\u201d flag. Since these backups contain the TCC.db files, an attacker could mount those backups and determine the device\u2019s TCC policy without having full disk access.\n * **Environment variable poisoning** ([CVE-2020-9934](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-9934>)): It was discovered that the user\u2019s _tccd_ could build the path to the TCC.db file by expanding $HOME/Library/Application Support/com.apple.TCC/TCC.db. Since the user could manipulate the $HOME environment variable (as introduced to tccd by _l_aunchd), an attacker could plant a chosen TCC.db file in an arbitrary path, poison the $HOME environment variable, and make TCC.db consume that file instead.\n * **Bundle-conclusion issue** ([CVE-2021-30713](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30713>)): [First disclosed by Jamf](<https://www.jamf.com/blog/zero-day-tcc-bypass-discovered-in-xcsset-malware/>) in a blog post about the XCSSET malware family, this bug abused how macOS was deducing app bundle information. For example, suppose an attacker knows of a specific app that commonly has microphone access. In that case, they could plant their application code in the target app\u2019s bundle and \u201cinherit\u201d its TCC capabilities.\n\nApple has responded to those vulnerabilities with two changes: It protected the system-wide TCC.db via [System Integrity Protection](<https://developer.apple.com/documentation/security/disabling_and_enabling_system_integrity_protection>) (SIP), a macOS feature that prevents unauthorized code execution, and it enforced a TCC policy that only apps with full disk access can access the TCC.db files.\n\n\u201cNote, though, that this policy was also subsequently abused as some apps required such access to function properly (for example, the SSH daemon, [sshd](<https://man7.org/linux/man-pages/man8/sshd.8.html>)),\u201d Microsoft researchers noted.\n\nApple has since patched these vulnerabilities, but Microsoft said that its research shows that \u201cthe potential bypass to TCC.db can still occur.\u201d\n\nMicrosoft\u2019s very predictable, inarguable advice: \u201cWe encourage macOS users to apply these security updates as soon as possible.\u201d\n\n_Image courtesy of [Pixabay](<https://pixabay.com/photos/spying-eyes-strange-weird-4250251/>)._\n\n**Password** **Reset: ****[On-Demand Event](<https://threatpost.com/webinars/password-reset-claiming-control-of-credentials-to-stop-attacks/>):** Fortify 2022 with a password security strategy built for today\u2019s threats.

Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). This one is listed as [CVE-2021-30883](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30883>) and allows an application to execute arbitrary code with kernel privileges. Kernel privileges can be achieved by using a memory corruption issue in the "IOMobileFrameBuffer" component.\n\nKernel privileges are a serious matter as they offer an attacker more than administrator privileges. In kernel mode, the executing code has complete and unrestricted access to the underlying hardware. It can execute any CPU instruction and reference any memory address. Kernel mode is generally reserved for the lowest-level, most trusted functions of the operating system.\n\nResearchers have already found that this vulnerability is exploitable from the browser, which makes it extra worrying.\n\n> We can confirm that the recently patched iOS 15.0.2 vulnerability, CVE-2021-30883, is also accessible from the browser: perfect for 1-click & water-holing mobile attacks. This vulnerability is exploited in the wild. Update as soon as possible. <https://t.co/dhogxTM6pT>\n> \n> -- ZecOps (@ZecOps) [October 12, 2021](<https://twitter.com/ZecOps/status/1447804721771606016?ref_src=twsrc%5Etfw>)\n\nWatering holes are used as a highly targeted attack strategy. The attacker infects a website where they knows the intended victim(s) visits regularly. Depending on the nature of the infection, the attacker can single out their intended target(s) or just infect anyone that visits the site unprotected.\n\n### IOMobileFrameBuffer\n\nIOMobileFramebuffer is a kernel extension for managing the screen framebuffer. An earlier vulnerability in this extension, listed as [CVE-2021-30807](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30807>) was tied to the [Pegasus spyware](<https://blog.malwarebytes.com/privacy-2/2021/07/pegasus-spyware-has-been-here-for-years-we-must-stop-ignoring-it/>). This vulnerability also allowed an application to execute arbitrary code with kernel privileges. Coincidence? Or did someone take the entire IOMobileFramebuffer extension apart and save up the vulnerabilities for a rainy day?\n\nAnother iPhone exploit called [FORCEDENTRY](<https://blog.malwarebytes.com/exploits-and-vulnerabilities/2021/08/latest-iphone-exploit-forcedenrty-used-to-launch-pegasus-attack-against-bahraini-activists/>) was found to be used against Bahraini activists to launch the Pegasus spyware. Researchers at Citizen Lab disclosed this vulnerability and code to Apple, and it was listed as CVE-2021-30860.\n\n### Undisclosed\n\nAs is usual for Apple, both the researcher that found the vulnerability and the circumstances under which the vulnerability used in the wild are kept secret. Apple didn't respond to a query about whether the previously found bug was being exploited by NSO Group's Pegasus surveillance software.\n\n### Zero-days for days\n\nOver the last months Apple has had to close quite a few zero-days in iOS, iPadOS,and macOS.

We shared our findings with Apple through [Coordinated Vulnerability Disclosure](<https://www.microsoft.com/msrc/cvd>) (CVD) via [Microsoft Security Vulnerability Research](<https://www.microsoft.com/msrc/msvr>) (MSVR). Apple released a fix for this vulnerability, now identified as [CVE-2021-30970](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30970>), as part of [security updates](<https://support.apple.com/en-us/HT212978>) released on December 13, 2021. We encourage macOS users to apply these security updates as soon as possible.\n\nIntroduced by Apple in 2012 on macOS Mountain Lion, TCC is essentially designed to help users configure the privacy settings of their apps, such as access to the device\u2019s camera, microphone, or location, as well as access to the user\u2019s calendar or iCloud account, among others. To protect TCC, Apple introduced a feature that prevents unauthorized code execution and enforced a policy that restricts access to TCC to only apps with full disk access. We discovered that it is possible to programmatically change a target user\u2019s home directory and plant a fake TCC database, which stores the consent history of app requests. If exploited on unpatched systems, this vulnerability could allow a malicious actor to potentially orchestrate an attack based on the user\u2019s protected personal data. For example, the attacker could hijack an app installed on the device\u2014or install their own malicious app\u2014and access the microphone to record private conversations or capture screenshots of sensitive information displayed on the user\u2019s screen.\n\nIt should be noted that other TCC vulnerabilities were previously reported and subsequently patched before our discovery. It was also through our examination of one of the latest fixes that we came across this bug. In fact, during this research, we had to update our proof-of-concept (POC) exploit because the initial version no longer worked on the latest macOS version, Monterey. This shows that even as macOS or other operating systems and applications become more hardened with each release, software vendors like Apple, security researchers, and the larger security community, need to continuously work together to identify and fix vulnerabilities before attackers can take advantage of them.\n\nMicrosoft security researchers continue to monitor the threat landscape to discover new vulnerabilities and attacker techniques that could affect macOS and other non-Windows devices. The discoveries and insights from our research enrich our protection technologies and solutions, such as [Microsoft Defender for Endpoint](<https://www.microsoft.com/security/business/threat-protection/endpoint-defender>), which allows organizations to gain visibility to their networks that are increasingly becoming heterogeneous. For example, this research informed the generic detection of behavior associated with this vulnerability, enabling Defender for Endpoint to immediately provide visibility and protection against exploits even before the patch is applied. Such visibility also enables organizations to detect, manage, respond to, and remediate vulnerabilities and cross-platform threats faster.\n\nIn this blog post, we will share some information about TCC, discuss previously reported vulnerabilities, and present our own unique findings.\n\n## TCC overview\n\nAs mentioned earlier, TCC is a technology that prevents apps from accessing users\u2019 personal information without their prior consent and knowledge. The user commonly manages it under System Preferences in macOS (System Preferences > Security & Privacy > Privacy):\n\n![Screenshot of the Security & Privacy pane on macOS](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig1-macOS-TCC-Security-and-Privacy-Pane-1024x893.png) Figure 1. The macOS Security & Privacy pane that serves as the front end of TCC. \n\nTCC maintains databases that contain consent history for app requests. Generally, when an app requests access to protected user data, one of two things can happen:\n\n 1. If the app and the type of request have a record in the TCC databases, then a flag in the database entry dictates whether to allow or deny the request without automatically and without any user interaction.\n 2. If the app and the type of request do not have a record in the TCC databases, then a prompt is presented to the user, who decides whether to grant or deny access. The said decision is backed into the databases so that succeeding similar requests will now fall under the first scenario.\n\nUnder the hood, there are two kinds of TCC databases. Each kind maintains only a subset of the request types:\n\n * **User-specific database:** contains stored permission types that only apply to the specific user profile; it is saved under **_~_**_/Library/Application Support/com.apple.TCC/TCC.db _and can be accessed by the user who owns the said profile\n * **System-wide database:** contains stored permission types that apply on a system level; it is saved under _/Library/Application Support/com.apple.TCC/TCC.db _and can be accessed by users with root or full disk access\n\nmacOS implements the TCC logic by using a special daemon called _tccd_. Indeed, there are at least two instances of tccd: one run by the user and the other by root.\n\n![Screenshot of two tccd instances](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig2-macOS-TCC-two-TCCD-instances-1024x56.png) Figure 2. Two tccd instances: per-user and system-wide. \n\nEach type of request starts with a _kTCCService_ prefix. While not an exhaustive list, below are some examples:\n\nRequest type| Description| Handled by \n---|---|--- \n**kTCCServiceLiverpool**| Location services access| User-specific TCC database \n**kTCCServiceUbiquity**| iCloud access| User-specific TCC database \n**kTCCServiceSystemPolicyDesktopFolder**| Desktop folder access| User-specific TCC database \n**kTCCServiceCalendar**| Calendar access| User-specific TCC database \n**kTCCServiceReminders**| Access to reminders| User-specific TCC database \n**kTCCServiceMicrophone**| Microphone access| User-specific TCC database \n**kTCCServiceCamera**| Camera access| User-specific TCC database \n**kTCCServiceSystemPolicyAllFiles**| Full disk access capabilities| System-wide TCC database \n**kTCCServiceScreenCapture**| Screen capture capabilities| System-wide TCC database \n_Table 1. Types of TCC requests._\n\nIt should also be noted that the _TCC.db_ file is a SQLITE database, so if a full disk access is granted to a user, they can view the database and even edit it:\n\n![Screenshot of TCC.db access table dump](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig3-macOS-TCC-dumping0-the-TCC-table-1024x492.png) Figure 3. Dumping the TCC.db access table, given a full disk access. \n\nThe database columns are self-explanatory, save for the _csreq_ column. The _csreq_ values contain a hexadecimal blob that encodes the code signing requirements for the app. These values can be calculated easily with the _codesign_ and [csreq](<https://developer.apple.com/library/archive/documentation/Security/Conceptual/CodeSigningGuide/RequirementLang/RequirementLang.html>) utilities, as seen in Figure 4 below:\n\n![Screenshot of building the csreq blob](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig4-macOS-TCC-Building-the-csreq-blob-1024x137.png) Figure 4. Building the csreq blob manually for an arbitrary app. \n\nGiven these, should a malicious actor gain full disk access to the TCC databases, they could edit it to grant arbitrary permissions to any app they choose, including their own malicious app. The affected user would also not be prompted to allow or deny the said permissions, thus allowing the app to run with configurations they may not have known or consented to.\n\n## Securing (and bypassing) TCC: Techniques and previously reported vulnerabilities\n\nPreviously, apps could access the TCC databases directly to view and even modify their contents. Given the risk of bypass mentioned earlier, Apple made two changes. First, Apple protected the system-wide _TCC.db_ via [System Integrity Protection](<https://developer.apple.com/documentation/security/disabling_and_enabling_system_integrity_protection>) (SIP), a macOS feature that prevents unauthorized code execution. Secondly, Apple enforced a TCC policy that only apps with full disk access can access the _TCC.db_ files. Note, though, that this policy was also subsequently abused as some apps required such access to function properly (for example, the SSH daemon, [sshd](<https://man7.org/linux/man-pages/man8/sshd.8.html>)).\n\nInterestingly, attackers can still find out whether a user\u2019s Terminal has full disk access by simply trying to list the files under _/Library/Application Support/com.apple.TCC_. A successful attempt means that the Terminal has full disk access capabilities, and an attacker can, therefore, freely modify the user\u2019s _TCC.db_.\n\nIn addition, there have been several previously reported vulnerabilities related to TCC bypass. These include the following:\n\n * **Time Machine mounts** ([CVE-2020-9771](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-9771>)): macOS offers a built-in backup and restore solution called [Time Machine](<https://support.apple.com/en-us/HT201250>). It was discovered that Time Machine backups could be mounted (using the _apfs_mount_ utility) with the \u201c_noowners_\u201d flag. Since these backups contain the _TCC.db_ files, an attacker could mount those backups and determine the device\u2019s TCC policy without having full disk access.\n * **Environment variable poisoning** ([CVE-2020-9934](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-9934>)): It was discovered that the user\u2019s _tccd_ could build the path to the _TCC.db_ file by expanding _$HOME/Library/Application Support/com.apple.TCC/TCC.db_. Since the user could manipulate the _$HOME_ environment variable (as introduced to _tccd_ by _launchd_), an attacker could plant a chosen _TCC.db_ file in an arbitrary path, poison the _$HOME_ environment variable, and make _TCC.db_ consume that file instead.\n * **Bundle conclusion issue** ([CVE-2021-30713](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30713>)): [First disclosed by Jamf](<https://www.jamf.com/blog/zero-day-tcc-bypass-discovered-in-xcsset-malware/>) in a blog post about the XCSSET malware family, this bug abused how macOS was deducing app bundle information. For example, suppose an attacker knows of a specific app that commonly has microphone access. In that case, they could plant their application code in the target app\u2019s bundle and \u201cinherit\u201d its TCC capabilities.\n\nApple has since patched these vulnerabilities. However, based on our research, the potential bypass to _TCC.db_ can still occur. The following section discusses the vulnerability we discovered and some details about the POC exploits we developed to prove the said vulnerability.\n\n## Modifying the home directory: The \u2018powerdir\u2019 vulnerability\n\nIn assessing the previous TCC vulnerabilities, we evaluated how Apple fixed each issue. One fix that caught our attention was for CVE-2020-9934 (the _$HOME_ environment variable poisoning vulnerability). The fix can be seen in the __db_open_ function in _tccd_:\n\n![Screenshot of the tccd fix for CVE-2020-9934](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig5-macOS-TCC-tccd-fix.png) Figure 5. The tccd fix for CVE-2020-9934. \n\nWe noted that instead of expanding the _$HOME_ environment variable, Apple decided to invoke [getpwuid()](<https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/getpwuid.3.html>) on the current user (retrieved with [getuid()](<https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man2/getuid.2.html>)). First, the _getpwuid_ function retrieves a structure in memory (_struct password*_) that contains information about the given user. Then, _tccd_ extracts the _pwdir_ member from it. This _pwdir_ member includes the user\u2019s home directory, and its value persists even after the _$HOME_ environment variable is modified.\n\nWhile the solution indeed prevents an attack by environment variable poisoning, it does not protect against the core issue. Thus, we set out to investigate: can an app programmatically change the user\u2019s home directory and plant a fake _TCC.db_ file?\n\n### The first POC exploit\n\nOur first attempt to answer the above question was simple: plant a fake _TCC.db_ file and change the home directory using the Directory Services command-line utility ([dscl](<https://www.unix.com/man-page/osx/1/dscl/>)):\n\n![](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Exploitb.png)\n\nWhile requiring root access, we discovered that this works only if the app is granted with the TCC policy _kTCCServiceSystemPolicySysAdminFiles_, which the local or user-specific _TCC.db _maintains. That is weaker than having full disk access, but we managed to bypass that restriction with the [dsexport](<https://www.unix.com/man-page/osx/1/dsexport/>) and [dsimport](<https://www.unix.com/man-page/osx/1/dsimport/>) utilities.\n\nNext, simply by exporting the Directory Services entry of a user, manipulating the output file, and importing the file again, we managed to bypass the _dscl_ TCC policy restriction.\n\nOur first POC exploit, therefore, does the following:\n\n 1. Get a _csreq_ blob for the target app.\n 2. Plant a fake _TCC.db_ file with required access and the _csreq_ blob.\n 3. Export the user\u2019s Directory Services entry with _dsexport_.\n 4. Modify the Directory Services entry to change the user\u2019s home directory.\n 5. Import the modified Directory Services entry with _dsimport_.\n 6. Stop the user\u2019s _tccd_ and reboot the process.\n\nUsing this exploit, an attacker could change settings on any application. In the screenshot below, we show how the exploit could allow attackers to enable microphone and camera access on any app, for example, Teams.\n\n![Screenshot of the working exploit](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig6-macOS-TCC-POC.png) Figure 6. Our first working POC exploit working without a popup notification from TCC. \n\nWe reported our initial findings to the Apple product security team on July 15, 2021, before becoming aware of a [similar bypass](<https://wojciechregula.blog/post/change-home-directory-and-bypass-tcc-aka-cve-2020-27937/>) presented by Wojciech Regu\u0142a and Csaba Fitzl at BlackHat USA 2021 in August. However, our exploit still worked even after Apple fixed the said similar finding (now assigned as [CVE-2020-27937](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-27937>)). Therefore, we still considered our research to be a new vulnerability.\n\n### Monterey release and the second POC exploit\n\nWe shared our findings to Apple through [Coordinated Vulnerability Disclosure](<https://www.microsoft.com/msrc/cvd>) (CVD) via [Microsoft Security Vulnerability Research](<https://www.microsoft.com/msrc/msvr>) (MSVR) before the release of macOS Monterey in October. However, upon the release of the said version, we noticed that our initial POC exploit no longer worked because of the changes made in how the _dsimport_ tool works. Thus, we looked for another way of changing the home directory silently.\n\nWhile examining macOS Monterey, we came across _/usr/libexec/configd_, an Apple binary shipped with the said latest macOS release that is a System Configuration daemon responsible for many configuration aspects of the local system. There are three aspects of _configd_ that we took note and made use of:\n\n 1. It is an Apple-signed binary entitled with \u201c_com.apple.private.tcc.allow_\u201d with the value _kTCCServiceSystemPolicySysAdminFiles_. This means it can change the home directory silently.\n 2. It has extensibility in configuration agents, which are macOS Bundles under the hood. This hints that it might load a custom Bundle, meaning we could inject code for our purposes.\n 3. It does not have the hardened runtime flag to load custom configuration agents. While this aspect is most likely by design, it also means we could load completely unsigned code into it.\n\nBy running _configd _with the _-t_ option, an attacker could specify a custom Bundle to load. Therefore, our new POC exploit replaces the _dsexport_ and _dsimport_ method of changing the user\u2019s home directory with a _configd_ code injection. This results in the same outcome as our first POC exploit, which allows the modification of settings to grant, for example, any app like Teams, to access the camera, among other services.\n\nAs before, we shared our latest findings with Apple. Again, we want to thank their product security team for their cooperation.\n\n## Detecting the powerdir vulnerability with Microsoft Defender for Endpoint\n\nOur research on the powerdir vulnerability is yet another example of the tight race between software vendors and malicious actors: that despite the continued efforts of the former to secure their applications through regular updates, other vulnerabilities will inevitably be uncovered, which the latter could exploit for their own gain. And as system vulnerabilities are possible entry points for attackers to infiltrate an organization\u2019s network, comprehensive protection is needed to allow security teams to manage vulnerabilities and threats across all platforms.\n\n[Microsoft Defender for Endpoint](<https://www.microsoft.com/security/business/threat-protection/endpoint-defender>) is an industry-leading, cloud-powered endpoint security solution that lets organizations manage their heterogeneous computing environments through a unified security console.

We shared our findings with Apple through [Coordinated Vulnerability Disclosure](<https://www.microsoft.com/msrc/cvd>) (CVD) via [Microsoft Security Vulnerability Research](<https://www.microsoft.com/msrc/msvr>) (MSVR). Apple released a fix for this vulnerability, now identified as [CVE-2021-30970](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30970>), as part of [security updates](<https://support.apple.com/en-us/HT212978>) released on December 13, 2021. We encourage macOS users to apply these security updates as soon as possible.\n\nIntroduced by Apple in 2012 on macOS Mountain Lion, TCC is essentially designed to help users configure the privacy settings of their apps, such as access to the device\u2019s camera, microphone, or location, as well as access to the user\u2019s calendar or iCloud account, among others. To protect TCC, Apple introduced a feature that prevents unauthorized code execution and enforced a policy that restricts access to TCC to only apps with full disk access. We discovered that it is possible to programmatically change a target user\u2019s home directory and plant a fake TCC database, which stores the consent history of app requests. If exploited on unpatched systems, this vulnerability could allow a malicious actor to potentially orchestrate an attack based on the user\u2019s protected personal data. For example, the attacker could hijack an app installed on the device\u2014or install their own malicious app\u2014and access the microphone to record private conversations or capture screenshots of sensitive information displayed on the user\u2019s screen.\n\nIt should be noted that other TCC vulnerabilities were previously reported and subsequently patched before our discovery. It was also through our examination of one of the latest fixes that we came across this bug. In fact, during this research, we had to update our proof-of-concept (POC) exploit because the initial version no longer worked on the latest macOS version, Monterey. This shows that even as macOS or other operating systems and applications become more hardened with each release, software vendors like Apple, security researchers, and the larger security community, need to continuously work together to identify and fix vulnerabilities before attackers can take advantage of them.\n\nMicrosoft security researchers continue to monitor the threat landscape to discover new vulnerabilities and attacker techniques that could affect macOS and other non-Windows devices. The discoveries and insights from our research enrich our protection technologies and solutions, such as [Microsoft Defender for Endpoint](<https://www.microsoft.com/security/business/threat-protection/endpoint-defender>), which allows organizations to gain visibility to their networks that are increasingly becoming heterogeneous. For example, this research informed the generic detection of behavior associated with this vulnerability, enabling Defender for Endpoint to immediately provide visibility and protection against exploits even before the patch is applied. Such visibility also enables organizations to detect, manage, respond to, and remediate vulnerabilities and cross-platform threats faster.\n\nIn this blog post, we will share some information about TCC, discuss previously reported vulnerabilities, and present our own unique findings.\n\n## TCC overview\n\nAs mentioned earlier, TCC is a technology that prevents apps from accessing users\u2019 personal information without their prior consent and knowledge. The user commonly manages it under System Preferences in macOS (System Preferences > Security & Privacy > Privacy):\n\n![Screenshot of the Security & Privacy pane on macOS](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig1-macOS-TCC-Security-and-Privacy-Pane-1024x893.png) Figure 1. The macOS Security & Privacy pane that serves as the front end of TCC. \n\nTCC maintains databases that contain consent history for app requests. Generally, when an app requests access to protected user data, one of two things can happen:\n\n 1. If the app and the type of request have a record in the TCC databases, then a flag in the database entry dictates whether to allow or deny the request without automatically and without any user interaction.\n 2. If the app and the type of request do not have a record in the TCC databases, then a prompt is presented to the user, who decides whether to grant or deny access. The said decision is backed into the databases so that succeeding similar requests will now fall under the first scenario.\n\nUnder the hood, there are two kinds of TCC databases. Each kind maintains only a subset of the request types:\n\n * **User-specific database:** contains stored permission types that only apply to the specific user profile; it is saved under **_~_**_/Library/Application Support/com.apple.TCC/TCC.db _and can be accessed by the user who owns the said profile\n * **System-wide database:** contains stored permission types that apply on a system level; it is saved under _/Library/Application Support/com.apple.TCC/TCC.db _and can be accessed by users with root or full disk access\n\nmacOS implements the TCC logic by using a special daemon called _tccd_. Indeed, there are at least two instances of tccd: one run by the user and the other by root.\n\n![Screenshot of two tccd instances](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig2-macOS-TCC-two-TCCD-instances-1024x56.png) Figure 2. Two tccd instances: per-user and system-wide. \n\nEach type of request starts with a _kTCCService_ prefix. While not an exhaustive list, below are some examples:\n\nRequest type| Description| Handled by \n---|---|--- \n**kTCCServiceLiverpool**| Location services access| User-specific TCC database \n**kTCCServiceUbiquity**| iCloud access| User-specific TCC database \n**kTCCServiceSystemPolicyDesktopFolder**| Desktop folder access| User-specific TCC database \n**kTCCServiceCalendar**| Calendar access| User-specific TCC database \n**kTCCServiceReminders**| Access to reminders| User-specific TCC database \n**kTCCServiceMicrophone**| Microphone access| User-specific TCC database \n**kTCCServiceCamera**| Camera access| User-specific TCC database \n**kTCCServiceSystemPolicyAllFiles**| Full disk access capabilities| System-wide TCC database \n**kTCCServiceScreenCapture**| Screen capture capabilities| System-wide TCC database \n_Table 1. Types of TCC requests._\n\nIt should also be noted that the _TCC.db_ file is a SQLITE database, so if a full disk access is granted to a user, they can view the database and even edit it:\n\n![Screenshot of TCC.db access table dump](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig3-macOS-TCC-dumping0-the-TCC-table-1024x492.png) Figure 3. Dumping the TCC.db access table, given a full disk access. \n\nThe database columns are self-explanatory, save for the _csreq_ column. The _csreq_ values contain a hexadecimal blob that encodes the code signing requirements for the app. These values can be calculated easily with the _codesign_ and [csreq](<https://developer.apple.com/library/archive/documentation/Security/Conceptual/CodeSigningGuide/RequirementLang/RequirementLang.html>) utilities, as seen in Figure 4 below:\n\n![Screenshot of building the csreq blob](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig4-macOS-TCC-Building-the-csreq-blob-1024x137.png) Figure 4. Building the csreq blob manually for an arbitrary app. \n\nGiven these, should a malicious actor gain full disk access to the TCC databases, they could edit it to grant arbitrary permissions to any app they choose, including their own malicious app. The affected user would also not be prompted to allow or deny the said permissions, thus allowing the app to run with configurations they may not have known or consented to.\n\n## Securing (and bypassing) TCC: Techniques and previously reported vulnerabilities\n\nPreviously, apps could access the TCC databases directly to view and even modify their contents. Given the risk of bypass mentioned earlier, Apple made two changes. First, Apple protected the system-wide _TCC.db_ via [System Integrity Protection](<https://developer.apple.com/documentation/security/disabling_and_enabling_system_integrity_protection>) (SIP), a macOS feature that prevents unauthorized code execution. Secondly, Apple enforced a TCC policy that only apps with full disk access can access the _TCC.db_ files. Note, though, that this policy was also subsequently abused as some apps required such access to function properly (for example, the SSH daemon, [sshd](<https://man7.org/linux/man-pages/man8/sshd.8.html>)).\n\nInterestingly, attackers can still find out whether a user\u2019s Terminal has full disk access by simply trying to list the files under _/Library/Application Support/com.apple.TCC_. A successful attempt means that the Terminal has full disk access capabilities, and an attacker can, therefore, freely modify the user\u2019s _TCC.db_.\n\nIn addition, there have been several previously reported vulnerabilities related to TCC bypass. These include the following:\n\n * **Time Machine mounts** ([CVE-2020-9771](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-9771>)): macOS offers a built-in backup and restore solution called [Time Machine](<https://support.apple.com/en-us/HT201250>). It was discovered that Time Machine backups could be mounted (using the _apfs_mount_ utility) with the \u201c_noowners_\u201d flag. Since these backups contain the _TCC.db_ files, an attacker could mount those backups and determine the device\u2019s TCC policy without having full disk access.\n * **Environment variable poisoning** ([CVE-2020-9934](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-9934>)): It was discovered that the user\u2019s _tccd_ could build the path to the _TCC.db_ file by expanding _$HOME/Library/Application Support/com.apple.TCC/TCC.db_. Since the user could manipulate the _$HOME_ environment variable (as introduced to _tccd_ by _launchd_), an attacker could plant a chosen _TCC.db_ file in an arbitrary path, poison the _$HOME_ environment variable, and make _TCC.db_ consume that file instead.\n * **Bundle conclusion issue** ([CVE-2021-30713](<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-30713>)): [First disclosed by Jamf](<https://www.jamf.com/blog/zero-day-tcc-bypass-discovered-in-xcsset-malware/>) in a blog post about the XCSSET malware family, this bug abused how macOS was deducing app bundle information. For example, suppose an attacker knows of a specific app that commonly has microphone access. In that case, they could plant their application code in the target app\u2019s bundle and \u201cinherit\u201d its TCC capabilities.\n\nApple has since patched these vulnerabilities. However, based on our research, the potential bypass to _TCC.db_ can still occur. The following section discusses the vulnerability we discovered and some details about the POC exploits we developed to prove the said vulnerability.\n\n## Modifying the home directory: The \u2018powerdir\u2019 vulnerability\n\nIn assessing the previous TCC vulnerabilities, we evaluated how Apple fixed each issue. One fix that caught our attention was for CVE-2020-9934 (the _$HOME_ environment variable poisoning vulnerability). The fix can be seen in the __db_open_ function in _tccd_:\n\n![Screenshot of the tccd fix for CVE-2020-9934](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig5-macOS-TCC-tccd-fix.png) Figure 5. The tccd fix for CVE-2020-9934. \n\nWe noted that instead of expanding the _$HOME_ environment variable, Apple decided to invoke [getpwuid()](<https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/getpwuid.3.html>) on the current user (retrieved with [getuid()](<https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man2/getuid.2.html>)). First, the _getpwuid_ function retrieves a structure in memory (_struct password*_) that contains information about the given user. Then, _tccd_ extracts the _pwdir_ member from it. This _pwdir_ member includes the user\u2019s home directory, and its value persists even after the _$HOME_ environment variable is modified.\n\nWhile the solution indeed prevents an attack by environment variable poisoning, it does not protect against the core issue. Thus, we set out to investigate: can an app programmatically change the user\u2019s home directory and plant a fake _TCC.db_ file?\n\n### The first POC exploit\n\nOur first attempt to answer the above question was simple: plant a fake _TCC.db_ file and change the home directory using the Directory Services command-line utility ([dscl](<https://www.unix.com/man-page/osx/1/dscl/>)):\n\n![](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Exploitb.png)\n\nWhile requiring root access, we discovered that this works only if the app is granted with the TCC policy _kTCCServiceSystemPolicySysAdminFiles_, which the local or user-specific _TCC.db _maintains. That is weaker than having full disk access, but we managed to bypass that restriction with the [dsexport](<https://www.unix.com/man-page/osx/1/dsexport/>) and [dsimport](<https://www.unix.com/man-page/osx/1/dsimport/>) utilities.\n\nNext, simply by exporting the Directory Services entry of a user, manipulating the output file, and importing the file again, we managed to bypass the _dscl_ TCC policy restriction.\n\nOur first POC exploit, therefore, does the following:\n\n 1. Get a _csreq_ blob for the target app.\n 2. Plant a fake _TCC.db_ file with required access and the _csreq_ blob.\n 3. Export the user\u2019s Directory Services entry with _dsexport_.\n 4. Modify the Directory Services entry to change the user\u2019s home directory.\n 5. Import the modified Directory Services entry with _dsimport_.\n 6. Stop the user\u2019s _tccd_ and reboot the process.\n\nUsing this exploit, an attacker could change settings on any application. In the screenshot below, we show how the exploit could allow attackers to enable microphone and camera access on any app, for example, Teams.\n\n![Screenshot of the working exploit](https://www.microsoft.com/security/blog/uploads/securityprod/2022/01/Fig6-macOS-TCC-POC.png) Figure 6. Our first working POC exploit working without a popup notification from TCC. \n\nWe reported our initial findings to the Apple product security team on July 15, 2021, before becoming aware of a [similar bypass](<https://wojciechregula.blog/post/change-home-directory-and-bypass-tcc-aka-cve-2020-27937/>) presented by Wojciech Regu\u0142a and Csaba Fitzl at BlackHat USA 2021 in August.

It has been said that a [leaked list of 50,000](<https://techcrunch.com/2021/07/19/toolkit-nso-pegasus-iphone-android/>) phone numbers of potential surveillance targets was obtained by Paris-based journalism nonprofit Forbidden Stories and Amnesty International.\n\nPegasus spyware is a surveillance software created by Israeli cyber intelligence firm NSO Group. Pegasus is one such software developed to gain access to your phone without consent and gather personal and sensitive information and deliver it to the user spying on you.\n\n### Attack Vectors and Impact of Pegasus Spyware\n\nThe first version of the spyware was detected in 2016 and used spear-phishing to infect a smartphone. It now adopts a different and more sophisticated approach for reaching new targets. It can infect a device using the "[zero-click](<https://www.aljazeera.com/news/2020/12/21/al-jazeera-journalists-hacked-by-spyware-sold-by-israeli-firm>)" attack done by exploiting the vulnerabilities present on the victim device. The "zero-click" attack happened earlier in December 2020 using iMessage vulnerabilities. Also, in [2019](<https://www.ft.com/content/4da1117e-756c-11e9-be7d-6d846537acab>) using the WhatsApp vulnerabilities.\n\nThe attack vectors for the Pegasus spyware are the vulnerabilities present on the devices: OS-level message (SMS) or iMessage app, WhatsApp, or other vulnerabilities that can be exploited.\n\nOnce Pegasus spyware is installed on the device, it can effectively monitor any activity you perform on it. This includes reading or copying your messages, extracting your media files, accessing your browser history, recording your calls, and much more.\n\n![](https://blog.qualys.com/wp-content/uploads/2021/07/Pegasus-capabilities-final-updated-1070x872.png)\n\n### VMDR for Mobile Devices Helps Protect from Pegasus Spyware\n\n[Qualys VMDR for Mobile Devices](<https://www.qualys.com/apps/vulnerability-management-detection-response/mobile-devices/>) detects devices that are potentially prone to Pegasus spyware based on the vulnerabilities mentioned below, which is a proactive approach. Pegasus is sophisticated spyware with anti-forensic and self-destruct features that make it difficult to detect. If it is uninstalled later, it does not leave any trace. VMDR for Mobile Devices must therefore detect if the device is vulnerable to Pegasus rather than detecting the presence of Pegasus spyware itself.\n\n#### iOS Pegasus:\n\nAll iOS devices are vulnerable to the following CVEs that are fixed in the latest iOS versions that might be used to install Pegasus spyware and to get the details from the devices\n\n * CVE-2020-9954, CVE-2020-9956, CVE-2020-9947, CVE-2020-9950, CVE-2020-9988, CVE-2020-9989, CVE-2020-9941 \u2013 Fixed in iOS and iPadOS 14\n * CVE-2020-10017, CVE-2020-27908, CVE-2020-27909 \u2013 Fixed in iOS and iPadOS 14.2\n * CVE-2020-29610 \u2013 Fixed in iOS and iPadOS 14.3\n * CVE-2021-1838, CVE-2021-1746, CVE-2021-1743, CVE-2021-1763, CVE-2021-1768, CVE-2021-1745, CVE-2021-1762, CVE-2021-1767, CVE-2021-1753, CVE-2021-1781 \u2013 Fixed in iOS 14.4\n * CVE-2021-1879 \u2013 Fixed in iOS and iPadOS 14.4.2\n * CVE-2021-30743, CVE-2021-1883 \u2013 Fixed in iOS 14.5\n * CVE-2021-30665, CVE-2021-30663, CVE-2021-30666(iOS 12.5.3), CVE-2021-30661(iOS 12.5.3) \u2013 Fixed in iOS and iPadOS 14.5.1 & iOS 12.5.3\n * CVE-2021-30707, CVE-2021-30749, CVE-2021-30734 \u2013 Fixed in iOS and iPadOS 14.6\n * CVE-2021-30788, CVE-2021-30759, CVE-2021-30792, CVE-2021-30791 \u2013 Fixed in iOS and iPadOS 14.7\n\n_Note that more CVEs might be exploited by Pegasus of the old iOS versions, i.e., below 14.0. If you are using old iOS versions, then your device might be more vulnerable to Pegasus spyware._\n\nWith VMDR for Mobile Devices, quickly check the security posture of all your mobile devices across your enterprise to remove blind spots, continuously detect these vulnerabilities and prioritize them. This helps you to take appropriate actions on the impacted devices.\n\n![](https://blog.qualys.com/wp-content/uploads/2021/07/iOS-Inventory.png) ![](https://blog.qualys.com/wp-content/uploads/2021/07/CVE-Listing-Page.png)\n\n#### Android Pegasus:\n\nVMDR for Mobile Devices quickly detects and prioritizes all the WhatsApp vulnerabilities, other messaging app vulnerabilities, and OS vulnerabilities. Earlier, the attack of Pegasus was made through [WhatsApp](<https://www.whatsapp.com/security/advisories/2021/>) app vulnerabilities, i.e., the Pegasus spyware can be installed on the phone using these vulnerabilities.\n\n![](https://blog.qualys.com/wp-content/uploads/2021/07/Whatsapp-Vulnerabilities.png)\n\n#### Respond by Patching and Remediation\n\nVMDR for Mobile Devices helps you to get a view of all vulnerabilities along with their priorities. Prioritizing the vulnerabilities based on the severity helps you take corrective and preventive actions on the impacted devices.\n\nVMDR for Mobile Devices provides you the patch orchestration for Android devices that helps you rapidly remediate your Android assets. Patch orchestration helps you initiate the most relevant per-application version patches on the affected assets.\n\nYou do not have to create multiple jobs; one job will take care of all vulnerabilities of that application.\n\n![](https://blog.qualys.com/wp-content/uploads/2021/07/Patch_WhatsAppVul.png)\n\nVMDR for Mobile Devices will also detect the app installed from an unknown source and its configurations (available by the end of August). The Pegasus may be introduced or installed through an unknown source in Android and ask the user for the required permission to monitor activities.\n\n![](https://blog.qualys.com/wp-content/uploads/2021/07/App-Details.png)\n\nIn addition, VMDR for Mobile Devices detects all vulnerabilities of Android and iOS OS vulnerabilities fixed by Apple and Google in their security updates. These vulnerabilities lead Pegasus spyware to take control of the device.\n\nKeep an eye on the vulnerabilities detected by VMDR for Mobile Devices and take appropriate actions. That will help you to secure the devices from Pegasus spyware because the spyware can be installed only if the vulnerabilities are present on the device.\n\nAlso, if the devices are jailbroken or rooted, track them through the \u201cUnauthorized Root Access\u201d widget or use QQL (Qualys Query Language) \u2013 \u201casset.hasUnauthorizedRootAccess: Yes\u201d to find the compromised devices.\n\n![](https://blog.qualys.com/wp-content/uploads/2021/07/Dashboard-Unathorized-Root-Access_page1.png)\n\n### Get Started Now\n\n[Qualys VMDR for Mobile Devices](<https://www.qualys.com/apps/vulnerability-management-detection-response/mobile-devices/>) is available free for 30 days to help customers detect vulnerabilities, monitor critical device settings, and correlate updates with the correct app versions available on Google Play Store.
