CVE-2023-41081 Apache Tomcat Connectors (mod_jk) Information Disclosure Severity: Important Vendor: The Apache Software Foundation Versions Affected: - Apache Tomcat Connectors mod_jk Connector 1.2.0 to 1.2.48 Description: In some circumstances, such as when a configuration included"JkOptions +ForwardDirectories" but the configuration did not provide explicit mounts for all possible proxied requests, mod_jk would use an implicit mapping and map the request to the first defined worker. Such an implicit mapping could result in the unintended exposure of the status worker and/or bypass security constraints configured in httpd. As of JK 1.2.49, the implicit mapping functionality has been removed and all mappings must now be via explicit configuration.
Only mod_jk is affected by this issue. The ISAPI redirector is not affected. Mitigation: Users of affected versions should apply one of the following mitigations: - Upgrade to Apache Tomcat Connector (mod_jk) 1.2.49 or later. - Ensure explicit mounts are configured for all possible proxied requests Credit:This vulnerability was reported responsibly to the Tomcat security team by Karl von Randow.
