Description
IBM WebSphere 5.1 and WebSphere 5.0 allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct XSS attacks via an HTTP request with both a "Transfer-Encoding: chunked" header and a Content-Length header, which causes WebSphere 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."
Product(s):
- IBM WebSphere Application Server 5.0
- IBM WebSphere Application Server 5.1.0
