Vulnerability Overview

The SupportCandy – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 3.3.7. This is due to missing rate limiting on the OTP verification for guest login. This makes it possible for unauthenticated attackers to bypass authentication and gain unauthorized access to customer support tickets by brute forcing the 6-digit OTP code.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-307: Improper Restriction of Excessive Authentication Attempts

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.

How does WordSec protect against this?

The fix is the thing that ends this: SupportCandy 3.3.8 closes this, and updating the plugin is the step that ends it.
