The version of Firefox installed on the remote macOS or Mac OS X host is prior to 131.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-46 advisory.

  - A user who enables full-screen mode on a specially crafted web page could potentially be prevented from     exiting full screen mode.  This may allow spoofing of other sites as the address bar is no longer visible.
    This bug only affects Firefox Focus for Android. Other versions of Firefox are unaffected. (CVE-2024-9391)

  - A compromised content process could have allowed for the arbitrary loading of cross-origin pages.
    (CVE-2024-9392)

  - An attacker could, via a specially crafted multipart response, execute arbitrary JavaScript under the     `resource://pdf.js` origin.  This could allow them to access cross-origin PDF content. This access is     limited to same site documents by the Site Isolation feature on desktop clients, but full cross-origin     access is possible on Android versions. (CVE-2024-9393)

  - An attacker could, via a specially crafted multipart response, execute arbitrary JavaScript under the     `resource://devtools` origin.  This could allow them to access cross-origin JSON content. This access is     limited to same site documents by the Site Isolation feature on desktop clients, but full cross-origin     access is possible on Android versions. (CVE-2024-9394)

  - A specially crafted filename containing a large number of spaces could obscure the file's extension when     displayed in the download dialog. This bug only affects Firefox for Android. Other versions of Firefox are     unaffected. (CVE-2024-9395)

  - It is currently unknown if this issue is exploitable but a condition may arise where the structured clone     of certain objects could lead to memory corruption. (CVE-2024-9396)

  - A missing delay in directory upload UI could have made it possible for an attacker to trick a user into     granting permission via clickjacking. (CVE-2024-9397)

  - By checking the result of calls to `window.open` with specifically set protocol handlers, an attacker     could determine if the application which implements that protocol handler is installed. (CVE-2024-9398)

  - A website configured to initiate a specially crafted WebTransport session could crash the Firefox process     leading to a denial of service condition. (CVE-2024-9399)

  - A potential memory corruption vulnerability could be triggered if an attacker had the ability to trigger     an OOM at a specific moment during JIT compilation. (CVE-2024-9400)

  - Memory safety bugs present in Firefox 130, Firefox ESR 115.15, Firefox ESR 128.2, and Thunderbird 128.2.
    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-2024-9401)

  - Memory safety bugs present in Firefox 130, Firefox ESR 128.2, and Thunderbird 128.2. 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-2024-9402)

  - Memory safety bugs present in Firefox 130. 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-2024-9403)

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