Apache Tomcat Rewrite Valve Relative Path Traversal (GHSA-wmwf-9ccg-fff5 / CVE-2025-55752)

Date: 2025-10-28

1. Executive Summary

We reproduced the relative path traversal vulnerability affecting Apache Tomcat versions 8.5.6–8.5.100, 9.0.0.M11–9.0.108, 10.1.0-M1–10.1.44, and 11.0.0-M1–11.0.10. The issue arises when RewriteValve rules incorporate user-controlled query parameters into rewritten URLs. Tomcat normalises the rewritten URI before decoding it, permitting encoded ../ sequences to slip past security constraints. During our assessment we:

• Deployed a vulnerable Tomcat 9.0.108 instance with a rewrite rule representative of the affected applications.
• Confirmed that an encoded traversal payload (path=%2FWEB-INF%2Fweb.xml) retrieves protected resources (HTTP 200) that should be inaccessible.
