Software Updates: The recommended approach is to update the affected Bosch firmware to a fixed version. If an update is not possible in timely manner, users are recommended to follow the mitigations and workarounds described in the following section.
Firewalling: Disallowing connections from insecure networks to the camera by means of a firewall prevents the attacker from accessing the vulnerable interface.
IP Filtering: The camera has the possibility to whitelist networks or IP addresses to only allow access from trusted networks or IPs, preventing an attacker from accessing the camera.
Secure Configuration Environment: It is advised to use a Bosch tool like the Configuration Manager to configure the camera, that does not allow for issues like CSRF and XSS.
When using the web based configuration interface and currently being logged in as administrator, some security precautions can be taken to mitigate XSS and CSRF vulnerabilities:
