A Watchfire whitepaper reports an vulnerability in the Apache webserver. The vulnerability can be exploited by malicious people causing cross site scripting, web cache poisoining, session hijacking and most importantly the ability to bypass web application firewall protection. Exploiting this vulnerability requires multiple carefully crafted HTTP requests, taking advantage of an caching server, proxy server, web application firewall etc. This only affects installations where Apache is used as HTTP proxy in combination with the following web servers:

IIS/6.0 and 5.0 Apache 2.0.45 (as web server) apache 1.3.29 WebSphere 5.1 and 5.0 WebLogic 8.1 SP1 Oracle9iAS web server 9.0.2 SunONE web server 6.1 SP4
