CVE-2025-26343Network attack vector

Unauthorized account access via repeated PIN guessing

Published Feb 12, 2025 · Updated Feb 17, 2025

Weak authentication in Q-Free MAXTIME Suite 2.11.0 and earlier allows remote attackers to brute-force user PINs via crafted HTTP requests. The PIN authentication mechanism accepts repeated PIN attempts without sufficient resistance, allowing guesses to be tested until a valid user PIN is found. No account or user interaction is required; a successful guess grants unauthorized access to the corresponding account through the management web application.
