CVE-2023-43454Public exploitNetwork attack vector

Unauthenticated code execution via hostName command injection

Published Dec 1, 2023 · Updated Nov 26, 2024

Command injection in TOTOLINK X6000R firmware 9.4.0cu.652_B20230116 and 9.4.0cu.852_B20230719 allows remote attackers to execute code. The switchOpMode component processes the hostName parameter as a command without neutralizing command syntax when proto selects its default branch. No authentication or user interaction is required; setting proto to a value other than 3, 4, or 6 reaches the vulnerable branch and grants command execution on the router.
