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. History 2023-09-13 Original advisory 2023-09-28
