BluetoothAlias

CVE-2021-0931

  • Status: Completed.

  • Description: In getAlias of BluetoothDevice.java, there is a possible way to create misleading permission dialogs due to missing data filtering. This could lead to local information disclosure with User execution privileges needed. User interaction is needed for exploitation.

  • Type: ID

  • Severity: High

  • Links:

  1. MITRE
  2. Google source
  • Exploit: Modify the alias for every connected device to the victims phone to a misleading text.

  • Patch: Like Google source but also hooked the setAlias method to avoid allowing the usage of these characters also here.
