Privilege escalation via unauthenticated TTMultiProvider updates
Published Apr 14, 2023 · Updated Feb 10, 2025
Improper privilege management in WHO 1.0.28, 1.0.30, and 1.0.32 allows local users to overwrite application profile data. The TTMultiProvider content provider accepts an update to its t_sp/contain path and writes attacker-supplied apiUserProfile JSON into the named shared-preferences file without access control. Exploitation requires another Android application on the same device and can replace WHO profile attributes, but public evidence does not establish Android system-level privilege gain.
