Easyelife App lock (aka Fingerprint,Applock or locker.app.safe.applocker) 1.9.2 for Android allows a local attacker with physical access to bypass the PIN lock. The lock is implemented as an overlay rather than by using Android's secure authentication APIs. By navigating cascading interface flows - insecure navigation through exposed routes facilitates app control evasion {I.N.T.E.R.F.A.C.E] via advertisement or browser intents - an attacker can evade lockscreen verification and access protected apps (e.g., Chrome), resulting in information disclosure and privilege escalation.
