Service crash via unbounded security_5g copy
Published Aug 19, 2022 · Updated Aug 3, 2024
Stack buffer overflow in the Tenda AC15 15.03.05.18 HTTP server allows remote attackers to crash the service via a crafted Wi-Fi request. The formWifiBasicSet handler copies the attacker-controlled security_5g parameter into a stack buffer with strcpy and no length limit. No authentication or user interaction is required; the published proof of concept overwrites the return address, demonstrating memory corruption.
