Detailed vulnerability description
The vulnerability allows a remote attacker to spoof the client IP address and bypass IP-based access controls or audit logging.
The vulnerability exists due to use of a less trusted source in the getRealIpAddr() function in objects/functions.php when processing user-supplied HTTP headers. A remote attacker can send a specially crafted request with forged IP-related headers to spoof the client IP address and bypass IP-based access controls or audit logging.
The issue can also affect IP-based rate limiting and may have greater impact where localhost is trusted.
