CVE-2019-11892
A potential improper access control vulnerability exists in the JSON-RPC interface of the Bosch Smart Home Controller (SHC) before 9.8.905 that may result in reading or modification of the SHC’s configuration or triggering and restoring backups. In order to exploit the vulnerability, the adversary needs to have successfully paired an app or service, which requires user interaction.
CVE-2019-11893
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.
CVE-2019-11894
A potential improper access control vulnerability exists in the backup mechanism of the Bosch Smart Home Controller (SHC) before 9.8.905 that may result in unauthorized download of a backup. In order to exploit the vulnerability, the adversary needs to download the backup directly after a backup triggered by a legitimate user has been completed.
CVE-2019-11895
A potential improper access control vulnerability exists in the JSON-RPC interface of the Bosch Smart Home Controller (SHC) before 9.8.905 that may result in a successful denial of service of the SHC and connected sensors and actuators. In order to exploit the vulnerability, the adversary needs to have successfully paired an app or service, which requires user interaction.
CVE-2019-11896
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.
