Unauthenticated root code execution via DDP username 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. The DDP reboot request path fails to validate the supplied authentication username length before copying it into a fixed-length stack buffer. No authentication or user interaction is required, but the attacker must reach the access point from an adjacent network; successful exploitation grants root-level code execution.

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.
