How the CVE Works
CVE-2025-46701 exploits improper case sensitivity handling in Apache Tomcat’s CGI servlet. Attackers can bypass security constraints by manipulating the `pathInfo` component of a URI mapped to the CGI servlet. For example, if a path `/secure/` is restricted, an attacker could use `/SeCuRe/` to evade restrictions. This affects Tomcat versions 11.0.0-M1 to 11.0.6, 10.1.0-M1 to 10.1.40, and 9.0.0.M1 to 9.0.104. The vulnerability allows unauthorized access to protected resources, leading to potential data exposure or privilege escalation.
