Unauthenticated code execution via unchecked VLAN input
Published Apr 17, 2024 · Updated Aug 2, 2024
Stack-based buffer overflow in Tenda AC500 2.0.1.9(1307) allows remote attackers to crash the controller or execute code via VLAN input. The formSetVlanInfo handler accepts the vlan request parameter without enforcing the capacity of its destination stack buffer, allowing oversized input to overwrite adjacent stack data. No credentials or user interaction are required, and successful exploitation can interrupt controller service or run attacker-controlled code.
