CVE-2016-6808Buffer overflow in Apache Tomcat Connectors (mod_jk) before 1.2.42.
CVE-2023-41081Important: 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-2018-1323The IIS/ISAPI specific code in the Apache Tomcat JK ISAPI Connector 1.2.0 to 1.2.42 that normalised the requested path before matching it to the URI-worker map did not handle some edge cases correctly. If only a sub-set of the URLs supported by Tomcat were exposed via IIS, then it was possible for a specially constructed request to expose application functionality through the reverse proxy that was not intended for clients accessing Tomcat via the reverse proxy.
CVE-2018-11759The Apache Web Server (httpd) specific code that normalised the requested path before matching it to the URI-worker map in Apache Tomcat JK (mod_jk) Connector 1.2.0 to 1.2.44 did not handle some edge cases correctly. If only a sub-set of the URLs supported by Tomcat were exposed via httpd, then it was possible for a specially constructed request to expose application functionality through the reverse proxy that was not intended for clients accessing the application via the reverse proxy. It was also possible in some configurations for a specially constructed request to bypass the access controls configured in httpd. While there is some overlap between this issue and CVE-2018-1323, they are not identical.
CVE-2007-0774Stack-based buffer overflow in the map_uri_to_worker function (native/common/jk_uri_worker_map.c) in mod_jk.so for Apache Tomcat JK Web Server Connector 1.2.19 and 1.2.20, as used in Tomcat 4.1.34 and 5.5.20, allows remote attackers to execute arbitrary code via a long URL that triggers the overflow in a URI worker map routine.
CVE-2024-46544Incorrect Default Permissions vulnerability in Apache Tomcat Connectors allows local users to view and modify shared memory containing mod_jk configuration which may lead to information disclosure and/or denial of service.
This issue affects Apache Tomcat Connectors: from 1.2.9-beta through 1.2.49. Only mod_jk on Unix like systems is affected. Neither the ISAPI redirector nor mod_jk on Windows is affected.
Users are recommended to upgrade to version 1.2.50, which fixes the issue.
CVE-2014-8111Apache Tomcat Connectors (mod_jk) before 1.2.41 ignores JkUnmount rules for subtrees of previous JkMount rules, which allows remote attackers to access otherwise restricted artifacts via unspecified vectors.
CVE-2007-1860mod_jk in Apache Tomcat JK Web Server Connector 1.2.x before 1.2.23 decodes request URLs within the Apache HTTP Server before passing the URL to Tomcat, which allows remote attackers to access protected pages via a crafted prefix JkMount, possibly involving double-encoded .. (dot dot) sequences and directory traversal, a related issue to CVE-2007-0450.
CVE-2008-5519The JK Connector (aka mod_jk) 1.2.0 through 1.2.26 in Apache Tomcat allows remote attackers to obtain sensitive information via an arbitrary request from an HTTP client, in opportunistic circumstances involving (1) a request from a different client that included a Content-Length header but no POST data or (2) a rapid series of requests, related to noncompliance with the AJP protocol's requirements for requests containing Content-Length headers.
