Webtrends Analytics 8.0x Issue
The version of Tomcat packaged with version 8.0x of Webtrends contains a vulnerability with cache poisoning. Specifically, Jakarta Tomcat 5.0.19 (Coyote/1.1) and Tomcat 4.1.24 (Coyote/1.0) allow remote attackers to poison the web cache, bypass web application firewall protection, and conduct cross-site scripting (XSS) attacks via an HTTP request with both a “Transfer-Encoding: chunked” header and a Content-Length header, which causes Tomcat to incorrectly handle and forward the body of the request in a way that causes the receiving server to process it as a separate HTTP request, aka “HTTP Request Smuggling.”
Resolution
While it is possible to update Jakarta/Tomcat, this is not a supported solution and has not been tested by Webtrends QA department.
