Authenticated memory corruption via unchecked list copy
Published Mar 15, 2024 · Updated Apr 10, 2025
Stack-based buffer overflow in Tenda AC18 15.03.05.05 allows remote authenticated users to corrupt memory via a crafted POST request. The formSetQosBand path passes the list parameter to strcpy, which copies it into a fixed 256-byte stack buffer without checking its length. Administrative access is required, and the public proof of concept demonstrates overflow delivery but does not document reliable code execution.
