Authenticated memory corruption via unchecked list copy
Published Oct 23, 2024 · Updated Oct 23, 2024
Stack-based buffer overflow in Tenda RX9 and RX9 Pro 22.03.02.20 allows remote authenticated users to corrupt process memory. The /goform/SetNetControlList handler passes the POST list parameter from sub_4337EC to sub_4335DC, where strcpy copies it into a fixed-size stack buffer without a length check. Low-privileged access to the router management interface is required; the overwrite can compromise the affected device's confidentiality, integrity, and availability.
