Important: Information disclosure CVE-2018-1323

The IIS/ISAPI specific code 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 the application via the reverse proxy.

This was fixed in revision 1825658.

Affects: JK 1.2.0-1.2.42
