HTTP Request Smuggling Vulnerability in Microsoft IIS 5.0 and 6.0

CVE-2005-2089 · MEDIUM Severity

AV:N/AC:M/AU:N/C:N/I:P/A:N

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."
