Linux Distros Unpatched Vulnerability : CVE-2022-39957

high Nessus Plugin ID 224947

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.

 - The OWASP ModSecurity Core Rule Set (CRS) is affected by a response body bypass. A client can issue an HTTP Accept header field containing an optional charset parameter in order to receive the response in an encoded form. Depending on the charset, this response can not be decoded by the web application firewall. A restricted resource, access to which would ordinarily be detected, may therefore bypass detection. The legacy CRS versions 3.0.x and 3.1.x are affected, as well as the currently supported versions 3.2.1 and 3.3.2. Integrators and users are advised to upgrade to 3.2.2 and 3.3.3 respectively.
 (CVE-2022-39957)

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

Solution

There is no known solution at this time.
