Unauthenticated relay control via replayed HTTP commands
Published Jul 14, 2022 · Updated May 5, 2025
Authentication bypass in Dingtian DT-R002 firmware 3.1.276A allows remote attackers to switch attached relays via replayed HTTP requests. The relay_cgi.cgi endpoint accepts cleartext relay-control parameters from a captured request without requiring authentication or verifying that the request is fresh and authorized. Network access and a captured or reproducible command are sufficient to turn either physical relay on or off, altering the state of connected equipment.
