CVE-2024-30622Public exploitNetwork attack vector

Code execution via unchecked mitInterface input length

Published Mar 29, 2024 · Updated Aug 13, 2024

Stack-based buffer overflow in Tenda FH1205 2.0.0.7(775) allows remote attackers to execute code or crash the router via mitInterface. The fromAddressNat request handler accepts an overlong mitInterface value without enforcing its length and writes past a fixed-size stack buffer. Unauthenticated network access to the router's management endpoint is sufficient; successful exploitation compromises the device or interrupts routing service.
