Synopsis

A mail client installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Thunderbird installed on the remote Windows host is prior to 128.10. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-32 advisory.

- A process isolation vulnerability in Thunderbird stemmed from improper handling of javascript: URIs, which could allow content to execute in the top-level document's process instead of the intended frame, potentially enabling a sandbox escape. (CVE-2025-4083)

- Thunderbird's update mechanism allowed a medium-integrity user process to interfere with the SYSTEM-level updater by manipulating the file-locking behavior. By injecting code into the user-privileged process, an attacker could bypass intended access controls, allowing SYSTEM-level file operations on paths controlled by a non-privileged user and enabling privilege escalation. (CVE-2025-2817)

- Modification of specific WebGL shader attributes could trigger an out-of-bounds read, which, when chained with other vulnerabilities, could be used to escalate privileges. This bug only affects Thunderbird for macOS. Other versions of Thunderbird are unaffected. (CVE-2025-4082)

- Due to insufficient escaping of the special characters in the copy as cURL feature, an attacker could trick a user into using this command, potentially leading to local code execution on the user's system.
This bug only affects Firefox for Windows. Other versions of Firefox are unaffected. (CVE-2025-4084)

- A vulnerability was identified in Thunderbird where XPath parsing could trigger undefined behavior due to missing null checks during attribute access. This could lead to out-of-bounds read access and potentially, memory corruption. (CVE-2025-4087)

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 Thunderbird version 128.10 or later.
