WordPress Plugin Vulnerabilities

WP Limit Login Attempts <= 2.6.5 - IP Spoofing

Description

The plugin prioritizes getting a visitor's IP from certain HTTP headers over PHP's REMOTE_ADDR, which makes it possible to bypass IP-based restrictions on login forms.

Proof of Concept

Set HTTP_CLIENT_IP or HTTP_X_FORWARDED_FOR as used in wp_limit_getip() to spoof the IP address and bypass the block.
