Description
An application "com.pri.applock", which is pre-loaded on Kruger&Matz smartphones, allows a user to encrypt any application using user-provided PIN code or by using biometric data. Exposed ”com.android.providers.settings.fingerprint.PriFpShareProvider“ content provider's public method query() allows any other malicious application, without any granted Android system permissions, to exfiltrate the PIN code.
Only version (version name: 13, version code: 33) was tested and confirmed to have this vulnerability. Application update was released in April 2025.
