Remote code execution via unbounded readUsb formatting
Published Oct 28, 2024 · Updated Oct 28, 2024
A stack-based buffer overflow in Tenda AC1206 20241027 and earlier allows remote attackers to execute code through the ATE service. After /goform/ate starts UDP port 7329, readUsb passes attacker-controlled fileName data to sprintf without bounds checking and overflows the 512-byte mntFileName stack buffer. A network path to the management endpoint and UDP service is sufficient; the published proof of concept crashes a child thread, while crafted input permits code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
