Shuffle Master Deck Mate 2 Insecure Update Chain_CVE-2025-34500

7 / 10

HIGH

CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

Description

Deck Mate 2's firmware update mechanism accepts packages without cryptographic signature verification, encrypts them with a single hard-coded AES key shared across devices, and uses a truncated HMAC for integrity validation. Attackers with access to the update interface - typically via the unit's USB update port - can craft or modify firmware packages to execute arbitrary code as root, allowing persistent compromise of the device's integrity and deck randomization process. Physical or on-premises access remains the most likely attack path, though network-exposed or telemetry-enabled deployments could theoretically allow remote exploitation if misconfigured. The vendor confirmed that firmware updates have been issued to correct these update-chain weaknesses and that USB update access has been disabled on affected units.
