Root code execution via DDP password overflow
Published May 3, 2024 · Updated Sep 18, 2024
Stack-based buffer overflow in D-Link DAP-2622 firmware 1.00 and earlier allows network-adjacent attackers to execute arbitrary code. The DDP service copies the Change ID Password request's new-password value into a fixed-length stack buffer without validating its length. DDP is enabled by default, no authentication is required, and successful exploitation runs attacker-controlled code as root on the access point.

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.
