Summaryinfo

A vulnerability marked as critical has been reported in Light & Wonder Deck Mate 1. This affects an unknown function of the component Firmware Update Handler. Performing a manipulation results in signature verification. This vulnerability is known as CVE-2025-34503. The attack may be carried out on the physical device. No exploit is available.

Detailsinfo

A vulnerability was found in Light & Wonder Deck Mate 1. It has been classified as critical. This affects an unknown code of the component Firmware Update Handler. The manipulation with an unknown input leads to a signature verification vulnerability. CWE is classifying the issue as CWE-347. The product does not verify, or incorrectly verifies, the cryptographic signature for data. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Deck Mate 1 executes firmware directly from an external EEPROM without verifying authenticity or integrity. An attacker with physical access can replace or reflash the EEPROM to run arbitrary code that persists across reboots. Because this design predates modern secure-boot or signed-update mechanisms, affected systems should be physically protected or retired from service. The vendor has not indicated that firmware updates are available for this legacy model.

The weakness was published by Joseph Tartaro. The advisory is shared at ioactive.com. This vulnerability is uniquely identified as CVE-2025-34503 since 04/15/2025. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

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