Wertheim Safecontroller Family 65000 Hardware For Vault Rooms Safe Deposit Locker System Microcontroller
Monthly
Cryptographic key disclosure in Wertheim SafeController Family 65000 (AssemblyVersion 6.11.8130.22319), a microcontroller-based safe deposit locker system, allows adjacent attackers to decrypt protected communications. The device uses a weak custom (proprietary) cryptographic algorithm with hard-coded keys, and researchers at SEC-VLab demonstrated both breaking the encryption routine and recovering the key by intercepting sufficient traffic. No public exploit identified at time of analysis and the vulnerability is not listed in CISA KEV.
