The version of Firefox ESR installed on the remote Windows host is prior to 91.5. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-02 advisory.

  - Mozilla developers Calixte Denizet, Kershaw Chang, Christian Holler, Jason Kratzer, Gabriele Svelto, Tyson     Smith, Simon Giesecke, and Steve Fink reported memory safety bugs present in Firefox 95 and Firefox ESR     91.4. 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-2022-22751)

  - It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox.
    (CVE-2021-4140)

  - A race condition could have allowed bypassing the fullscreen notification which could have lead to a     fullscreen window spoof being unnoticed. This bug only affects Thunderbird for Windows. Other operating     systems are unaffected. (CVE-2022-22746)

  - When navigating from inside an iframe while requesting fullscreen access, an attacker-controlled tab could     have made the browser unable to leave fullscreen mode. (CVE-2022-22743)

  - When inserting text while in edit mode, some characters might have lead to out-of-bounds memory access     causing a potentially exploitable crash. (CVE-2022-22742)

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

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5229-1 advisory.

    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, spoof the     browser UI, bypass security restrictions, obtain sensitive information across domains, or execute     arbitrary code.
