Official description
The Android application BINHDRM26 com.bdrm.superreboot 1.0.3, exposes several critical actions through its exported broadcast receivers. These exposed actions can allow any app on the device to send unauthorized broadcasts, leading to unintended consequences. The vulnerability is particularly concerning because these actions include powering off, system reboot & entering recovery mode.

The underlying weakness: Use of Implicit Intent for Sensitive Communication
The Android application uses an implicit intent for transmitting sensitive data to other applications.
How developers prevent this class of flaw
- If the application only requires communication with its own components, then the destination is always known, and an explicit intent could be used.
