How to fix?

Upgrade Oracle:8 mod_session to version 0:2.4.37-65.0.1.module+el8.10.0+90368+a557a4bf.1 or higher.
This issue was patched in ELSA-2024-4720.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mod_session package and not the mod_session package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

Improper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to map URLs to filesystem locations that are permitted to be served by the server but are not intentionally/directly reachable by any URL, resulting in code execution or source code disclosure.

Substitutions in server context that use a backreferences or variables as the first segment of the substitution are affected.  Some unsafe RewiteRules will be broken by this change and the rewrite flag "UnsafePrefixStat" can be used to opt back in once ensuring the substitution is appropriately constrained.
