Jakarta Tomcat 5.0.19 (Coyote/1.1) and Tomcat 4.1.24 (Coyote/1.0) 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 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."

Security readout for executives and security teams

This is an old Apache Jakarta Tomcat request-smuggling flaw. A remote attacker could confuse how Tomcat and a downstream server interpret one HTTP request, enabling cache poisoning, WAF bypass, or XSS in affected deployments. Exposure is most likely in legacy Tomcat 4.1.x or 5.0.x systems, or products bundling those Tomcat versions. Internet-facing proxy, cache, or WAF chains increase business relevance. Treat as a legacy exposure hunt. It is not KEV-listed in the provided bundle, but affected systems can undermine perimeter controls and cached web content. Mitigation focus: Inventory Tomcat and products bundling Tomcat, especially legacy 4.1.x and 5.0.x deployments.; Upgrade affected Tomcat versions according to Apache and vendor advisories.; Check vendor advisories for embedded Tomcat in appliances or enterprise products..
