Mozilla Firefox ESR < 128.3

high Nessus Plugin ID 207981

Synopsis

A web browser installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote Windows host is prior to 128.3. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-47 advisory.

- 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 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 write data to the user's clipboard, bypassing the user prompt, during a certain sequence of navigational events. (CVE-2024-8900)

- 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)

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

Solution

Upgrade to Mozilla Firefox ESR version 128.3 or later.
