Insecure Firmware Validation in Snap One OvrC Pro Devices

CVE-2023-28386 · CRITICAL Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

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.
