Handle Vulnerability Found in Firefox on Windows, Risk of Sandbox Escape
Information:
Mozilla Firefox is an open-source web browser developed by Mozilla, a non-profit organization. It is known for its speed, security, and user privacy. Firefox uses its own Quantum engine and does not rely on Chromium like other browsers, providing a unique approach to managing personal data. It features automatic blocking of trackers and third-party cookies, as well as support for installing extensions to customize the browsing experience. Additionally, Firefox is available on multiple operating systems, including Windows, macOS, Linux, iOS, and Android, and offers developer tools and a sync system that enables seamless usage across devices.
Incident:
CVE-2025-2857 is a critical severity security vulnerability discovered in the Mozilla Firefox web browser on Windows operating systems. The root cause lies in the improper handling of Windows handles within the inter-process communication (IPC) mechanism-an essential framework for coordinating operations between the browser’s parent and child processes.
Typically, Firefox employs a sandboxing model to restrict the privileges of child processes, preventing them from directly accessing system resources. However, this vulnerability allows a compromised child process to bypass the handle permission model by crafting spoofed IPC messages or by performing unauthorized handle reuse or duplication. As a result, the parent process may return a handle with higher privileges than intended, without enforcing adequate validation checks.
If successfully exploited, this flaw enables an attacker to break out of the sandbox isolation and execute arbitrary code on the target system without requiring administrator privileges or any user interaction—making it a zero-click attack vector.
This vulnerability shares similarities with CVE-2025-2783 in Google Chrome, which has previously been exploited in the wild. Both rely on manipulating the handle management logic to achieve privilege escalation and gain access to protected system resources.
Recommendation:
- Update Mozilla Firefox to the latest version (at least 136.0.4)
- Enable Endpoint Protection or EDR
- Avoid using outdated or unsupported versions
- Use the browser with a non-administrator user account
The important things is Security systems. We must concern and monitor as usual.
