CVE-2005-2089

Microsoft IIS 5.0/6.0 HTTP Request Smuggling via Transfer-Encoding and Content-Length

Title source: llm
STIX 2.1

Description

Microsoft IIS 5.0 and 6.0 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 IIS 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."
