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."

Security readout for executives and security teams

This is an old IBM WebSphere request-smuggling issue. A remote client can send an ambiguous HTTP request that WebSphere may split or forward incorrectly, letting downstream systems see a hidden second request. Risk is highest where legacy WebSphere sits behind caches, WAFs, or shared front ends. Exposure is likely limited to legacy IBM WebSphere 5.0 or 5.1 deployments, especially internet-facing or proxied applications using web caches, WAFs, reverse proxies, or shared application front ends. Treat as high priority if legacy WebSphere remains exposed. The technology is old, but the impact crosses application, cache, and WAF boundaries, which can undermine controls executives may assume are protective. Mitigation focus: Inventory and prioritize any remaining IBM WebSphere 5.0 or 5.1 systems.; Check IBM X-Force and vendor guidance for supported fixes or upgrade paths.; Retire or isolate unsupported WebSphere instances from internet-facing traffic..
