Detailsinfo

A vulnerability was found in Light & Wonder Deck Mate 2. It has been declared as critical. Affected by this vulnerability is an unknown part of the component Update Interface. The manipulation with an unknown input leads to a hard-coded key vulnerability. The CWE definition for the vulnerability is CWE-321. The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was disclosed by Joseph Tartaro. The advisory is shared at ioactive.com. This vulnerability is known as CVE-2025-34500 since 04/15/2025. The exploitation appears to be easy. An attack has to be approached locally. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
