Senserva AI Opinion for CVE-2024-38475
Apache HTTP Server's mod_rewrite module is among the most widely deployed pieces of software on the internet, and this improper output escaping flaw lets attackers map URLs to filesystem locations that were never meant to be reachable, resulting in code execution or source code disclosure. The EPSS score is a flat 100%, the Severity rating is Critical at CVSS 9.1, and CISA confirmed exploitation on 2025-05-01. Any internet-facing Apache server using rewrite rules should be treated as a target.
Do this: Update Apache HTTP Server on internet-facing systems first and audit mod_rewrite rules for patterns that expose filesystem paths.
