CVE-2024-50340 (opens in a new tab)How to fix?
Upgrade Debian:12 symfony to version 5.4.23+dfsg-1+deb12u3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream symfony package and not the symfony package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
symfony/runtime is a module for the Symphony PHP framework which enables decoupling PHP applications from global state. When the register_argv_argc php directive is set to on , and users call any URL with a special crafted query string, they are able to change the environment or debug mode used by the kernel when handling the request. As of versions 5.4.46, 6.4.14, and 7.1.7 the SymfonyRuntime now ignores the argv values for non-SAPI PHP runtimes. All users are advised to upgrade. There are no known workarounds for this vulnerability.
