Observable response discrepancy in Q-Free MAXTIME Suite 2.11.0 and earlier allows remote attackers to enumerate valid usernames. The login page produces distinguishable results for existent and nonexistent account names, although the responsible response property is undisclosed. No authentication or user interaction is required, and disclosed account names can support brute-force or credential-stuffing attacks.
