Authentication bypass via implicit first-worker mapping
Published Sep 13, 2023 · Updated Sep 25, 2024
Authentication bypass in mod_jk in Apache Tomcat Connectors 1.2.0 through 1.2.48 allows remote attackers to access protected workers. For an unmapped request, mod_jk implicitly selects the first configured worker instead of requiring an explicit URI-to-worker mapping. Exposure requires ForwardDirectories and incomplete explicit mounts; the request can reveal the status worker or bypass httpd constraints.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
