Published Apr 29, 2024 · Updated Nov 4, 2024
Authentication bypass in Yealink VP59 Microsoft Teams Phone firmware 91.15.0.118 allows physically proximate attackers to disable its phone lock. The Walkie Talkie menu processes the lock-disable action while the phone is locked instead of requiring the configured unlock path. The attack requires physical interaction with a signed-in device and exposes functions protected by the phone lock; no remote path is reported.
