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.

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5809 advisory.

    Multiple vulnerabilities have been found in the Symfony PHP framework     which could lead to privilege escalation, information disclosure,     incorrect validation or an open redirect.

    For the stable distribution (bookworm), these problems have been fixed in     version 5.4.23+dfsg-1+deb12u3.

    We recommend that you upgrade your symfony packages.

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Symfony versions prior to 5.4.46 or 6.x prior to 6.4.14 or 7.x prior to 7.1.7 is vulnerable when the register_argc_argv 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.

Note that since the vulnerable Symfony component is embedded in Laravel, the plugin is likely to detect a vulnerable Laravel instance.
