Mod_proxy_cluster: mod_proxy_cluster: response body corruption via crlf injection

A flaw was found in  mod_proxy_cluster. This vulnerability, a Carriage Return Line Feed (CRLF) injection in the decodeenc() function, allows a remote attacker to bypass input validation.

Exploitation requires network access to the MCMP protocol port, but no authentication is needed.
