Name of the Vulnerable Software and Affected Versions Bell HomeHub 3000 version SG48222070

Description An issue allows remote authenticated users to retrieve the serial number via the "cgi/json-req" endpoint. This is considered an information leak because the serial number is intended to prove an actor's physical access to the device.

Recommendations For Bell HomeHub 3000 version SG48222070, as a temporary workaround, consider restricting access to the "cgi/json-req" endpoint to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
