Description Sam Fowler 2018-03-13 05:49:48 UTC 
The ISAPI redirector code in Apache Tomcat JK Connector before version 1.2.43 does not properly handle HTTP request paths in certain edge cases. A remote attacker could exploit this by sending a crafted request to expose application functionality through the reverse proxy.
