The version of Firefox ESR installed on the remote Windows host is prior to 102.11. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-17 advisory.

  • In multiple cases browser prompts could have been obscured by popups controlled by content. These could have led to potential user confusion and spoofing attacks. (CVE-2023-32205)

  • An out-of-bound read could have led to a crash in the RLBox Expat driver. (CVE-2023-32206)

  • A missing delay in popup notifications could have made it possible for an attacker to trick a user into granting permissions. (CVE-2023-32207)

  • A type checking bug would have led to invalid code being compiled. (CVE-2023-32211)

  • An attacker could have positioned a <code>datalist</code> element to obscure the address bar.
    (CVE-2023-32212)

  • When reading a file, an uninitialized value could have been used as read limit. (CVE-2023-32213)

  • Protocol handlers <code>ms-cxh</code> and <code>ms-cxh-full</code> could have been leveraged to trigger a denial of service. Note: This attack only affects Windows. Other operating systems are not affected.
    (CVE-2023-32214)

  • Mozilla developers and community members Gabriele Svelto, Andrew Osmond, Emily McDonough, Sebastian Hengst, Andrew McCreight and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 112 and Firefox ESR 102.10. 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-2023-32215)

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