Synopsis

A web browser installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote macOS or Mac OS X 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.
