The version of Firefox installed on the remote macOS or Mac OS X host is prior to 97.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-04 advisory.

  - A Time-of-Check Time-of-Use bug existed in the Maintenance (Updater) Service that could be abused to grant     Users write access to an arbitrary directory. This could have been used to escalate to SYSTEM access. This     bug only affects Firefox on Windows. Other operating systems are unaffected. (CVE-2022-22753)

  - If a user installed an extension of a particular type, the extension could have auto-updated itself and     while doing so, bypass the prompt which grants the new version the new requested permissions.
    (CVE-2022-22754)

  - By using XSL Transforms, a malicious webserver could have served a user an XSL document that would     continue to execute JavaScript (within the bounds of the same-origin policy) even after the tab was     closed. (CVE-2022-22755)

  - If a user was convinced to drag and drop an image to their desktop or other folder, the resulting object     could have been changed into an executable script which would have run arbitrary code after the user     clicked on it. (CVE-2022-22756)

  - Remote Agent, used in WebDriver, did not validate the Host or Origin headers. This could have allowed     websites to connect back locally to the user's browser to control it.  This bug only affected Firefox when     WebDriver was enabled, which is not the default configuration. (CVE-2022-22757)

  - When clicking on a tel: link, USSD codes, specified after a <code></code> character, would be included in     the phone number.  On certain phones, or on certain carriers, if the number was dialed this could perform     actions on a user's account, similar to a cross-site request forgery attack. This bug only affects Firefox     for Android. Other operating systems are unaffected. (CVE-2022-22758)

  - If a document created a sandboxed iframe without <code>allow-scripts</code>, and subsequently appended an     element to the iframe's document that e.g. had a JavaScript event handler - the event handler would have     run despite the iframe's sandbox. (CVE-2022-22759)

  - When importing resources using Web Workers, error messages would distinguish the difference between     <code>application/javascript</code> responses and non-script responses.  This could have been abused to     learn information cross-origin. (CVE-2022-22760)

  - Web-accessible extension pages (pages with a moz-extension:// scheme) were not correctly enforcing the     frame-ancestors directive when it was used in the Web Extension's Content Security Policy.
    (CVE-2022-22761)

  - Under certain circumstances, a JavaScript alert (or prompt) could have been shown while another website     was displayed underneath it. This could have been abused to trick the user.  This bug only affects Firefox     for Android. Other operating systems are unaffected. (CVE-2022-22762)

  - Mozilla developers Paul Adenot and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox     96 and Firefox ESR 91.5. 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. (CVE-2022-22764)

  - Mozilla developers and community members Gabriele Svelto, Sebastian Hengst, Randell Jesup, Luan Herrera,     Lars T Hansen, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 96. 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-2022-0511)

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