Windu CMS 4.1 - Brute-Force Protection Bypass via loginError Parameter

Title source: llm
STIX 2.1

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.
