The version of Firefox installed on the remote macOS or Mac OS X host is prior to 109.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-01 advisory.

  - A compromised web child process could disable web security opening restrictions, leading to a new child     process being spawned within the <code>file://</code> context. Given a reliable exploit primitive, this     new process could be exploited again leading to arbitrary file read. (CVE-2023-23597)

  - Due to the Firefox GTK wrapper code's use of text/plain for drag data and GTK treating all text/plain     MIMEs containing file URLs as being dragged a website could arbitrarily read a file via a call to     <code>DataTransfer.setData</code>. (CVE-2023-23598)

  - When copying a network request from the developer tools panel as a curl command the output was not being     properly sanitized and could allow arbitrary commands to be hidden within. (CVE-2023-23599)

  - Per origin notification permissions were being stored in a way that didn't take into account what browsing     context the permission was granted in. This lead to the possibility of notifications to be displayed     during different browsing sessions. This bug only affects Firefox for Android. Other operating systems are     unaffected. (CVE-2023-23600)

  - Navigations were being allowed when dragging a URL from a cross-origin iframe into the same tab which     could lead to website spoofing attacks (CVE-2023-23601)

  - A mishandled security check when creating a WebSocket in a WebWorker caused the Content Security Policy     connect-src header to be ignored. This could lead to connections to restricted origins from inside     WebWorkers. (CVE-2023-23602)

  - Regular expressions used to filter out forbidden properties and values from style directives in calls to     <code>console.log</code> weren't accounting for external URLs. Data could then be potentially exfiltrated     from the browser. (CVE-2023-23603)

  - A duplicate <code>SystemPrincipal</code> object could be created when parsing a non-system html document     via <code>DOMParser::ParseFromSafeString</code>. This could have lead to bypassing web security checks.
    (CVE-2023-23604)

  - Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108 and     Firefox ESR 102.6. Some of these bugs showed evidence of memory corruption and we presume that with enough     effort some of these could have been exploited to run arbitrary code. (CVE-2023-23605)

  - Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108. Some     of these bugs showed evidence of memory corruption and we presume that with enough effort some of these     could have been exploited to run arbitrary code. (CVE-2023-23606)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An update of the mozjs package has been released.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5816-1 advisory.

    Niklas Baumstark discovered that a compromised web child process of Firefox could disable web security     opening restrictions, leading to a new child process being spawned within the file:// context. An attacker     could potentially exploits this to obtain sensitive information. (CVE-2023-23597)

    Tom Schuster discovered that Firefox was not performing a validation check on GTK drag data. An attacker     could potentially exploits this to obtain sensitive information. (CVE-2023-23598)

    Vadim discovered that Firefox was not properly sanitizing a curl command output when copying a network     request from the developer tools panel. An attacker could potentially exploits this to hide and execute     arbitrary commands. (CVE-2023-23599)

    Luan Herrera discovered that Firefox was not stopping navigation when dragging a URL from a cross-origin     iframe into the same tab. An attacker potentially exploits this to spoof the user. (CVE-2023-23601)

    Dave Vandyke discovered that Firefox did not properly implement CSP policy when creating a WebSocket in a     WebWorker. An attacker who was able to inject markup into a page otherwise protected by a Content Security     Policy may have been able to inject an executable script. (CVE-2023-23602)

    Dan Veditz discovered that Firefox did not properly implement CSP policy on regular expression when using     console.log. An attacker potentially exploits this to exfiltrate data from the browser. (CVE-2023-23603)

    Nika Layzell discovered that Firefox was not performing a validation check when parsing a non-system html     document via DOMParser::ParseFromSafeString. An attacker potentially exploits this to bypass web security     checks. (CVE-2023-23604)

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information across domains, or execute arbitrary code. (CVE-2023-23605, CVE-2023-23606)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

The remote host is affected by the vulnerability described in GLSA-202305-06 (Mozilla Firefox: Multiple Vulnerabilities)

  - An out of date library (libusrsctp) contained vulnerabilities that could potentially be exploited. This     vulnerability affects Firefox < 108. (CVE-2022-46871)

  - An attacker who compromised a content process could have partially escaped the sandbox to read arbitrary     files via clipboard-related IPC messages.<br>*This bug only affects Thunderbird for Linux. Other operating     systems are unaffected.*. This vulnerability affects Firefox < 108, Firefox ESR < 102.6, and Thunderbird <     102.6. (CVE-2022-46872)

  - Because Firefox did not implement the <code>unsafe-hashes</code> CSP directive, an attacker who was able     to inject markup into a page otherwise protected by a Content Security Policy may have been able to inject     executable script. This would be severely constrained by the specified Content Security Policy of the     document. This vulnerability affects Firefox < 108. (CVE-2022-46873)

  - A file with a long filename could have had its filename truncated to remove the valid extension, leaving a     malicious extension in its place. This could potentially led to user confusion and the execution of     malicious code.<br/>*Note*: This issue was originally included in the advisories for Thunderbird 102.6,     but a patch (specific to Thunderbird) was omitted, resulting in it actually being fixed in Thunderbird     102.6.1. This vulnerability affects Firefox < 108, Thunderbird < 102.6.1, Thunderbird < 102.6, and Firefox     ESR < 102.6. (CVE-2022-46874)

  - The executable file warning was not presented when downloading .atloc and .ftploc files, which can run     commands on a user's computer. <br>*Note: This issue only affected Mac OS operating systems. Other     operating systems are unaffected.*. This vulnerability affects Firefox < 108, Firefox ESR < 102.6, and     Thunderbird < 102.6. (CVE-2022-46875)

  - By confusing the browser, the fullscreen notification could have been delayed or suppressed, resulting in     potential user confusion or spoofing attacks. This vulnerability affects Firefox < 108. (CVE-2022-46877)

  - Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory     safety bugs present in Thunderbird 102.5. Some of these bugs showed evidence of memory corruption and we     presume that with enough effort some of these could have been exploited to run arbitrary code. This     vulnerability affects Firefox < 108, Firefox ESR < 102.6, and Thunderbird < 102.6. (CVE-2022-46878)

  - Mozilla developers and community members Lukas Bernhard, Gabriele Svelto, Randell Jesup, and the Mozilla     Fuzzing Team reported memory safety bugs present in Firefox 107. Some of these bugs showed evidence of     memory corruption and we presume that with enough effort some of these could have been exploited to run     arbitrary code. This vulnerability affects Firefox < 108. (CVE-2022-46879)

  - A missing check related to tex units could have led to a use-after-free and potentially exploitable     crash.<br />*Note*: This advisory was added on December 13th, 2022 after we better understood the impact     of the issue. The fix was included in the original release of Firefox 105. This vulnerability affects     Firefox ESR < 102.6, Firefox < 105, and Thunderbird < 102.6. (CVE-2022-46880)

  - An optimization in WebGL was incorrect in some cases, and could have led to memory corruption and a     potentially exploitable crash. This vulnerability affects Firefox < 106, Firefox ESR < 102.6, and     Thunderbird < 102.6. (CVE-2022-46881)

  - A use-after-free in WebGL extensions could have led to a potentially exploitable crash. This vulnerability     affects Firefox < 107, Firefox ESR < 102.6, and Thunderbird < 102.6. (CVE-2022-46882)

  - A compromised web child process could disable web security opening restrictions, leading to a new child     process being spawned within the <code>file://</code> context. Given a reliable exploit primitive, this     new process could be exploited again leading to arbitrary file read.  (CVE-2023-23597)

  - Mozilla: Arbitrary file read from GTK drag and drop on Linux (CVE-2023-23598)

  - Mozilla: Malicious command could be hidden in devtools output (CVE-2023-23599)

  - Per origin notification permissions were being stored in a way that didn't take into account what browsing     context the permission was granted in. This lead to the possibility of notifications to be displayed     during different browsing sessions. This bug only affects Firefox for Android. Other operating systems are     unaffected.  (CVE-2023-23600)

  - Mozilla: URL being dragged from cross-origin iframe into same tab triggers navigation (CVE-2023-23601)

  - Mozilla: Content Security Policy wasn't being correctly applied to WebSockets in WebWorkers     (CVE-2023-23602)

  - Mozilla: Calls to <code>console.log</code> allowed bypasing Content Security Policy via format directive     (CVE-2023-23603)

  - A duplicate <code>SystemPrincipal</code> object could be created when parsing a non-system html document     via <code>DOMParser::ParseFromSafeString</code>. This could have lead to bypassing web security checks.
    (CVE-2023-23604)

  - Mozilla: Memory safety bugs fixed in Firefox 109 and Firefox ESR 102.7 (CVE-2023-23605)

  - Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108. Some     of these bugs showed evidence of memory corruption and we presume that with enough effort some of these     could have been exploited to run arbitrary code.  (CVE-2023-23606)
