  script_tag(name:"insight", value:"The mod_jk component of Apache Tomcat Connectors, an Apache 2 module to forward requests from Apache to Tomcat, 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 this security update, the implicit mapping functionality has been removed and all mappings must now be via explicit configuration. This issue affects Apache Tomcat Connectors (mod_jk only).

For Debian 10 buster, this problem has been fixed in version 1:1.2.46-1+deb10u2.

We recommend that you upgrade your libapache-mod-jk packages.

For the detailed security status of libapache-mod-jk please refer to its security tracker page at: [link moved to references]
