CVE-2023-27647Public exploit

Persistent app crash via unrestricted provider inserts

Published Apr 14, 2023 · Updated Feb 10, 2025

Incorrect default permissions in DUALSPACE Lock Master 2.2.4 allow local users to crash the app or expose sensitive data through its provider. SharedPrefProvider accepts insert calls from another app and persistently appends attacker-controlled values to SharedPreferences until startup exhausts memory. A malicious Android app with local execution can make the lock app fail on every restart; public sources do not identify readable sensitive values or the disclosure mechanism.
