Login bypass via replayed authentication hash
Published Feb 6, 2024 · Updated Jun 5, 2025
Authentication bypass in Intelbras Action RF 1200 1.2.2 and earlier and Action RG 1200 2.1.7 and earlier allows remote attackers to log in. The web authentication flow places the correct password hash in a cookie and accepts that hash as the password value when a later request replays it. Exploitation requires a prior successful browser login or interception of its traffic; replay then grants management-interface access without the plaintext password.
