CVE-2025-46701 – Improper Handling of Case Sensitivity lead to RCE on Apache Tomcat
A high-severity vulnerability, CVE-2025-46701, has been identified in Apache Tomcat, impacting versions 9.0.0.M1 to 9.0.104, 10.1.0-M1 to 10.1.40, and 11.0.0-M1 to 11.0.6. The issue stems from case-insensitive handling of the pathInfo component in CGI servlet mappings, allowing attackers to bypass security constraints by altering URI casing. Under certain conditions, this can lead to remote code execution (RCE). Apache has addressed the flaw in versions 9.0.105, 10.1.41, and 11.0.7. The IONIX research team successfully reproduced and validated the exploit, as detailed in this post.
