Remote code execution via stack overflow
Published Nov 27, 2023 · Updated Aug 2, 2024
Buffer overflow in Tenda AX1803 1.0.0.1 allows remote attackers to execute arbitrary code via the wpapsk_crypto parameter. The fromSetWirelessRepeat handler copies oversized input into a fixed-size stack buffer, overwriting control data. The endpoint is reached through the router network management interface; proof-of-concept input crashes the router while demonstrating the stated code-execution impact.
