Authenticated code execution via hex-decoding overflow
Published Dec 23, 2022 · Updated Apr 15, 2025
Stack overflow in SetWan2Settings in D-Link DIR-882 1.30B06 and DIR-878 1.30B08 allows remote authenticated users to execute code. The Password field reaches a hex-decoding loop that copies attacker-controlled bytes into a fixed-size stack buffer without a length check. Administrative access to the router management interface is required; a crafted HNAP request can crash the service or execute code as root.
