Bruteforce Protection Bypass in Windu CMS

Published Nov 18, 2025 · Updated Dec 5, 2025 · Assigned by CERT-PL

Description

Windu CMS implements weak client-side brute-force protection by using parameter loginError. Information about attempt count or timeout is not stored on the server, which allows a malicious attacker to bypass this brute-force protection by resetting this parameter.

Only version 4.1 was tested and confirmed as vulnerable.
This issue was fixed in version 4.1 build 2250.
