The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any files in that directory would be recursively deleted with the permissions of the uninstalling user account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary file deletion controlled by the non-privileged user. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and Thunderbird < 115.1.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any     files in that directory would be recursively deleted with the permissions of the uninstalling user     account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary     file deletion controlled by the non-privileged user. *This bug only affects Firefox on Windows. Other     operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and     Thunderbird < 115.1. (CVE-2023-4052)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Memory safety bugs present in Firefox 115, Firefox ESR 115.0, and Thunderbird 115.0. 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. This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and
    Thunderbird < 115.1. (CVE-2023-4057)

  - Offscreen Canvas did not properly track cross-origin tainting, which could have been used to access image
    data from another site in violation of same-origin policy. This vulnerability affects Firefox < 116,
    Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4045)

  - In some circumstances, a stale value could have been used for a global variable in WASM JIT analysis. This
    resulted in incorrect compilation and a potentially exploitable crash in the content process. This
    vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4046)

  - A bug in popup notifications delay calculation could have made it possible for an attacker to trick a user
    into granting permissions. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR
    < 115.1. (CVE-2023-4047)

  - An out-of-bounds read could have led to an exploitable crash when parsing HTML with DOMParser in low
    memory situations. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR <
    115.1. (CVE-2023-4048)

The version of mozilla-firefox installed on the remote host is prior to 115.1.0esr. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-216-01 advisory.

  - Offscreen Canvas did not properly track cross-origin tainting, which could have been used to access image     data from another site in violation of same-origin policy. This vulnerability affects Firefox < 116,     Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4045)

  - In some circumstances, a stale value could have been used for a global variable in WASM JIT analysis. This     resulted in incorrect compilation and a potentially exploitable crash in the content process. This     vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4046)

  - A bug in popup notifications delay calculation could have made it possible for an attacker to trick a user     into granting permissions. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR     < 115.1. (CVE-2023-4047)

  - An out-of-bounds read could have led to an exploitable crash when parsing HTML with DOMParser in low     memory situations. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR <     115.1. (CVE-2023-4048)

  - Race conditions in reference counting code were found through code inspection. These could have resulted     in potentially exploitable use-after-free vulnerabilities. This vulnerability affects Firefox < 116,     Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4049)

  - In some cases, an untrusted input stream was copied to a stack buffer without checking its size. This     resulted in a potentially exploitable crash which could have led to a sandbox escape. This vulnerability     affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4050)

  - The Firefox updater created a directory writable by non-privileged users.

This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary     file deletion controlled by the non-privileged user. *This bug only affects Firefox on Windows. Other     operating systems are unaffected.* This vulnerability affects Firefox < 116 and Firefox ESR < 115.1.
    (CVE-2023-4052)

  - When opening appref-ms files, Firefox did not warn the user that these files may contain malicious code.
    *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability     affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4054)

  - When the number of cookies per domain was exceeded in `document.cookie`, the actual cookie jar sent to the     host was no longer consistent with expected cookie jar state. This could have caused requests to be sent     with some cookies missing. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR     < 115.1. (CVE-2023-4055)

  - Memory safety bugs present in Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0, and     Thunderbird 102.13. 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. This vulnerability affects     Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4056)

  - Memory safety bugs present in Firefox 115, Firefox ESR 115.0, and Thunderbird 115.0.
