Synopsis

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

Description

The version of Firefox installed on the remote Windows host is prior to 131.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-46 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 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)

- 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)

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 version 131.0 or later.
