Estado: ModificadaAlta (8)—

A potential incorrect privilege assignment vulnerability exists in the app permission update API of the Bosch Smart Home Controller (SHC) before 9.8.905 that may result in a restricted app obtaining default app permissions. In order to exploit the vulnerability, the adversary needs to have successfully paired an app with restricted permissions, which required user interaction.
