CVE-2023-50473Network attack vector

Session compromise via fixed login SID

Published Dec 21, 2023 · Updated Aug 2, 2024

Session fixation in bill-ahmed qbit-matUI 1.16.4 allows remote attackers to obtain sensitive information through a fixed login SID. The /api/v2/auth/login handler in mock_backend/index.js assigns every successful login cookie the same literal SID instead of generating a unique session identifier. Exploitation requires low-privileged access and user interaction, and published evidence limits the consequence to session-related information exposure.
