Unauthenticated code execution via HNAP stack overflow
Published Mar 12, 2024 · Updated Aug 5, 2024
Stack-based buffer overflow in the HNAP service in D-Link DIR-822 firmware 2.02KRB09 and 2.03WWb01 allows remote attackers to execute code. The HNAP service writes attacker-controlled request data beyond a stack-allocated buffer, but published materials do not identify the affected function or request field. The service must be reachable from the router's LAN; successful exploitation runs arbitrary code on the router without credentials or user interaction.

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.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
