Service interruption via unauthenticated Z-Wave frame injection
Published Jan 9, 2022 · Updated Sep 16, 2024
Denial of service in Silicon Labs UZB-7 7.00 allows remote attackers to block event processing via a crafted Z-Wave frame. The S2 FIND_NODE_IN_RANGE handler accepts frames without adequate authentication or encryption and processes an invalid random payload. An unauthenticated attacker within Z-Wave radio range can suppress upcoming controller events, interrupting service without reported data access or modification.
