CVE-2025-34503 | BDVDB-2026-299338 Detail

Light & Wonder, Inc. / SHFL Entertainment, Inc. / Shuffle MasterDeck Mate 1

Description#

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.

Impact#

Per CVSS v4.0: confidentiality impact high, integrity impact high, availability impact high. Attack vector: physical.

Weaknesses#

  • CWE-347 Improper Verification of Cryptographic Signature
  • CWE-1326 Missing Immutable Root of Trust in Hardware
