CVE-2024-40239

Physical authentication bypass via uninvalidated biometric enrollment

Published Nov 8, 2024 · Updated Nov 13, 2024

Incorrect access control in Hitbytes Life : Personal Diary, Journal 17.5.0 allows physically proximate attackers to read protected diary data. The fingerprint lock remains valid after a new fingerprint is enrolled, and its disable control performs no identity check. Physical access that permits biometric enrollment or access to that control is required; successful abuse opens fingerprint-protected journals.
