CyberRota Analysis
AI-GeneratedRouille versions 0.3.3 through 3.6.2 are vulnerable to an HTTP request smuggling attack due to improper handling of the Transfer-Encoding header in its proxy implementation. This flaw allows remote attackers to manipulate HTTP message boundaries, potentially leading to desynchronization and unauthorized access to backend services. Organizations using affected versions of Rouille should prioritize remediation to mitigate the risk of exploitation.

Original NVD Description
Rouille 0.3.3 through 3.6.2 contains an HTTP request smuggling vulnerability that allows remote attackers to desynchronize HTTP message boundaries by exploiting improper header forwarding in the proxy implementation. The proxy in src/proxy.rs forwards the client's Transfer-Encoding header to upstream backends unchanged while transmitting a body already de-chunked by tiny_http, enabling CL.TE desynchronization attacks where attackers control where the backend believes the request body ends.
