The Apache HTTP server prior to 1.3.34, and 2.0.x prior to 2.0.55, when acting as an HTTP proxy, allows remote malicious users 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 Apache 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."
