Linux Distros Unpatched Vulnerability : CVE-2025-64500

high Nessus Plugin ID 275362

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - Symfony is a PHP framework for web and console applications and a set of reusable PHP components.
 Symfony's HttpFoundation component defines an object-oriented layer for the HTTP specification. Starting in version 2.0.0 and prior to version 5.4.50, 6.4.29, and 7.3.7, the `Request` class improperly interprets some `PATH_INFO` in a way that leads to representing some URLs with a path that doesn't start with a `/`.
 This can allow bypassing some access control rules that are built with this `/`-prefix assumption.
 Starting in versions 5.4.50, 6.4.29, and 7.3.7, the `Request` class now ensures that URL paths always start with a `/`. (CVE-2025-64500)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
