Apache Software Foundation · Apache Tomcat Connectors
The Apache Tomcat Connectors product's mod_jk (Apache Tomcat JK) Connector, in the Apache Web Server (httpd) code that normalises request paths before matching them to the URI-worker map, mishandles some edge cases. Where only a subset of Tomcat URLs is exposed through httpd, a specially constructed request can reach application functionality not intended for clients using the reverse proxy, and in some configurations it can also bypass access controls configured in httpd.
The 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.
