The version of Firefox ESR installed on the remote Windows host is prior to 91.9. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-17 advisory.

  • When reusing existing popups Firefox would have allowed them to cover the fullscreen notification UI, which could have enabled browser spoofing attacks. (CVE-2022-29914)

  • Documents in deeply-nested cross-origin browsing contexts could have obtained permissions granted to the top-level origin, bypassing the existing prompt and wrongfully inheriting the top-level permissions.
    (CVE-2022-29909)

  • Firefox behaved slightly differently for already known resources when loading CSS resources involving CSS variables. This could have been used to probe the browser history. (CVE-2022-29916)

  • Firefox did not properly protect against top-level navigations for an iframe sandbox with a policy relaxed through a keyword like <code>allow-top-navigation-by-user-activation</code>. (CVE-2022-29911)

  • Requests initiated through reader mode did not properly omit cookies with a SameSite attribute.
    (CVE-2022-29912)

  • Mozilla developers Andrew McCreight, Gabriele Svelto, Tom Ritter and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 99 and Firefox ESR 91.8. 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-2022-29917)

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