Unauthenticated root code execution via DDP buffer overflow
Published May 3, 2024 · Updated Sep 18, 2024
Stack-based buffer overflow in D-Link DAP-2622 firmware 1.00 and earlier allows remote attackers to execute code as root via DDP requests. The DDP Set AG Profile handler copies an oversized authentication username into a fixed-length stack buffer without validating its length. Exploitation requires adjacent-network access but no authentication, and successful code runs with root privileges.

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.
