What is CVE-2025-34500?
CVE-2025-34500 is a high-severity vulnerability in Light & Wonder, Inc. / SHFL Entertainment, Inc. / Shuffle Master, Inc. Deck Mate 2, published on 24 Oct 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
