Snap One AN-310-RT-4L2W -

Snap One OvrC cloud servers contain a route an attacker can use to bypass requirements and claim devices outright.

Snap One OvrC Pro devices versions 7.2 and prior do not validate firmware updates correctly. The device only calculates the MD5 hash of the firmware and does not check using a private-public key mechanism. The lack of complete PKI system firmware signature could allow attackers to upload arbitrary firmware updates, resulting in code execution.

Devices using Snap One OvrC cloud are sent to a web address when accessing a web management interface using a HTTP connection. Attackers could impersonate a device and supply malicious information about the device’s web server interface. By supplying malicious parameters, an attacker could redirect the user to arbitrary and dangerous locations on the web.

When supplied with a random MAC address, Snap One OvrC cloud servers will return information about the device. The MAC address of devices can be enumerated in an attack and the OvrC cloud will disclose their information.
