The vulnerability allows a remote attacker to perform a spoofing attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can spoof the user's IP address when proxying using mod_remoteip and mod_rewrite, as a result the fake IP address will be displayed in logs and will be passed to PHP scripts.
