The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2024:1198-1 advisory.

  - 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 Updated summary     (CVE-2023-41081)
