Welcome to an important security advisory provided by LinuxPatch. Today, we are addressing a significant cybersecurity vulnerability identified as CVE-2024-50340, which has been rated with a high severity score of 7.3. This security issue impacts the Symfony Runtime, a key module used in managing PHP applications by offering an elegant way to run applications smoothly without the global state dependency.
Symfony Runtime is designed to enable PHP applications to operate independently of the global state, providing a more reliable and modular system architecture. This component is crucial for developers using the Symfony PHP framework, as it helps in handling applications' life cycle efficiently and safely.
The vulnerability arises when the register_argv_argc PHP directive is set to on. In such cases, attackers can manipulate the query string in the URL to modify the environment or debug settings of the Symfony kernel during the request processing. This could lead to unauthorized modifications of application behavior, potentially exposing sensitive information or compromising the application's integrity.
The vulnerability affects versions of Symfony/runtime prior to 5.4.46, 6.4.14, and 7.1.7. Developers and administrators using earlier versions of these are highly vulnerable to potential exploits due to this issue.
All users of the affected Symfony Runtime versions are urged to update their systems immediately. The patches for these versions have been specifically designed to ignore argv values in non-SAPI PHP runtimes, closing off the vulnerability. Upgrading to the latest version is crucial and should be prioritized to protect your applications from potential attacks exploiting this vulnerability.
It is important to note that there are no known workarounds for this issue. The only effective solution is to upgrade to the fixed versions of Symfony Runtime. Delaying this action could expose your system to high risks.
This advisory underlines the urgency of addressing CVE-2024-50340 by upgrading the Symfony Runtime in your PHP applications. By taking swift and decisive actions, you can safeguard your environments against this significant security threat. Stay vigilant and ensure your systems are always up to date with the latest security patches.
