CVE-2025-54571 Information

Description

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.
