Authenticated code execution via unbounded mac copy
Published Dec 21, 2025 · Updated Dec 21, 2025
Stack-based buffer overflow in Tenda AC18 15.03.05.05 allows remote authenticated users to execute code via a crafted mac parameter. The /goform/GetParentControlInfo handler passes the attacker-controlled mac value to strcpy without a length check, overflowing a stack buffer. Low-privilege access to the HTTP management interface is required, and successful exploitation can execute code or crash the router.
