NVD Description

Note: Versions mentioned in the description apply only to the upstream mod_security package and not the mod_security package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. In versions 2.9.11 and below, an attacker can override the HTTP response’s Content-Type, which could lead to several issues depending on the HTTP scenario. For example, we have demonstrated the potential for XSS and arbitrary script source code disclosure in the latest version of mod_security2. This issue is fixed in version 2.9.12.
