FastCGI mod_fastcgi contains a flaw that may allow an attacker to discover authentication credentials. The issue is due to the subprocess_env table not properly sanitizing variables between authentication requests. This allows for the process to pass variables including REMOTE_PASSWD to other processing phases and may allow for disclosure to unauthorized individuals.
