WordPress Plugin Vulnerabilities
Titan Anti-spam & Security < 7.3.1 - Protection Bypass due to IP Spoofing
Description
The plugin does not properly checks HTTP headers in order to validate the origin IP address, allowing threat actors to bypass it's block feature by spoofing the headers.
Proof of Concept
The function wantispamp_get_ip() is vulnerable to IP spoofing because of the general usage of $_SERVER['HTTP_X_FORWARDED_FOR'] curl -i -H 'X_FORWARDED_FOR: 0.0.0.0' https://example.com
Affects Plugins
Fixed in version 7.3.1
