Important: Authentication Bypass CVE-2023-41081
The mod_jk component of Apache Tomcat Connectors 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.
This issue affects Apache Tomcat Connectors (mod_jk only): from 1.2.0 through 1.2.48.
Users are recommended to upgrade to version 1.2.49, which fixes the issue.

CVE-2023-41081 mod_jk vulnerability
Title: mod_jk vulnerability
Summary: mod_jk could allow unintended access to network services.
Karl von Randow discovered that mod_jk was vulnerable to an authentication
bypass. If the configuration did not provide explicit mounts for all
possible proxied requests, an attacker could possibly use this
vulnerability to bypass security constraints configured in httpd.
Instructions: In general, a standard system update will make all the necessary changes.
