Executive Summary

The vulnerability in SailingLab AppLock 4.3.8 for Android allows a local attacker with physical access to bypass the PIN lock.

This happens because the lock is implemented as an overlay rather than using Android's secure authentication APIs.

By navigating through cascading interface flows and exploiting insecure navigation via advertisement or browser intents, an attacker can evade the lockscreen verification.

This enables the attacker to access protected apps such as Chrome without entering the PIN.
