CVE-2023-28386 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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. EPSS estimates a 0.42% chance of exploitation in the next 30 days.

Description

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.
