Affected: Bitnami: tomcat

Improper Handling of Case Sensitivity vulnerability in Apache Tomcat's GCI servlet allows security constraint bypass of security constraints that apply to the pathInfo component of a URI mapped to the CGI servlet.

This issue affects Apache Tomcat: from 11.0.0 through 11.0.6, from 10.1.0 through 10.1.40, from 9.0.0 through 9.0.104. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected.

Users are recommended to upgrade to version 11.0.7, 10.1.41 or 9.0.105, which fixes the issue.

Tomcat is the servlet container that is used in the official Reference Implementation for the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed by Sun under the Java Community Process. Security Fix(es):

A vulnerability was found in Apache Tomcat up to 9.0.104/10.1.40/11.0.6 (Application Server Software) and classified as critical.Using CWE to declare the problem leads to CWE-178. The product does not properly account for differences in case sensitivity when accessing or determining the properties of a resource, leading to inconsistent results.Impacted is integrity.Upgrading to version 9.0.105, 10.1.41 or 11.0.7 eliminates this vulnerability.(CVE-2025-46701)
