Wertheim Safecontroller 5400 Hardware For Vault Rooms Safe Deposit Locker System Microcontroller
Monthly
Authentication bypass via replay attack affects Wertheim SafeController 5400 and Controller 5400 (AssemblyVersion 6.11.8130.22320) vault room safe deposit locker systems, where RS-485 traffic between the server and microcontroller flows without cryptographic protection. An adjacent attacker with physical access to the RS-485 bus can capture legitimate commands and replay them - for instance, repeatedly injecting a 'quit alarm' message to silently disable the safe's alarm. No public exploit identified at time of analysis, and there is no published CISA KEV listing or EPSS data for this physical-bus weakness.
