What is CVE-2024-7525?

The CVE-2024-7525 is a critical security issue that affects Mozilla Firefox and Thunderbird, allowing a web extension with minimal permissions to create a StreamFilter. This capability could enable malicious parties to read and modify the response body of HTTP requests across any site. Scored at a high severity level of 9.1, this vulnerability poses a significant threat due to the ease with which an attacker can exploit user data.

Software Affected

This vulnerability pertains to the following versions:

  • Mozilla Firefox versions prior to 129
  • Firefox Extended Support Release (ESR) prior to 115.14 and 128.1
  • Mozilla Thunderbird versions prior to 128.1 and 115.14

Firefox and Thunderbird are popular web browsers and email clients, respectively, developed by Mozilla. They are widely used for browsing the internet and managing emails, making their security paramount for individual and corporate users alike.

Technical Details of the Vulnerability

The core issue here revolves around the misuse of StreamFilter API in Firefox and Thunderbird. This API is intended to provide developers the means to interact with the content of web pages dynamically. However, the vulnerability allows a web extension with minimal permissions unauthorized access to use this API for intercepting and altering web communications invisibly.

This capability could lead to serious privacy breaches, including but not limited to data theft, session hijacking, and secondary attacks such as phishing or malware dissemination.

How to Protect Your Systems

Mitigating this threat involves updating the affected software to the latest versions as released by Mozilla:

  • Update Firefox to version 129 or later
