Amazon Linux 2023 : mod_security, mod_security-mlogc (ALAS2023-2025-1157)

medium Nessus Plugin ID 261741

Language:

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-1157 advisory.

 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. (CVE-2025-54571)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update mod_security --releasever 2023.8.20250908' or or 'dnf update --advisory ALAS2023-2025-1157 --releasever 2023.8.20250908' to update your system.
