Unauthenticated code execution via command injection
Published May 12, 2025 · Updated May 13, 2025
Command injection in Tenda FH451 firmware 1.0.0.9 allows remote attackers to execute code through the formSafeEmailFilter handler. The handler constructs a command from externally influenced request content without neutralizing command-altering special elements; the exact request field and command sink are undisclosed. No authentication or user interaction is required, and successful exploitation executes commands with the router service's privileges.
