Estado: ModificadaAlta (7.1)—

A potential incorrect privilege assignment vulnerability exists in the 3rd party pairing mechanism of the Bosch Smart Home Controller (SHC) before 9.8.907 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, which requires user interaction.
