Vulnerability Title
Busybox: busybox: http request smuggling via pipelined requests in httpd reverse proxy
来源: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in BusyBox httpd's reverse proxy feature. When the proxy is configured to forward requests matching a URL prefix to a backend server, only the first HTTP request on a TCP connection has its path rewritten. An attacker can send a pipelined second request that is relayed verbatim to the backend, bypassing the configured path restrictions. This allows accessing arbitrary paths on the backend server that were not intended to be exposed through the proxy.
