CVE-2022-44928Public exploitNetwork attack vector

Unauthenticated command execution via Maintenance input

Published Dec 2, 2022 · Updated Apr 24, 2025

OS command injection in the Maintenance function of D-Link DVG-G5402SP GE_1.03 allows remote attackers to execute arbitrary commands. The function passes attacker-controlled maintenance input to an operating-system command without neutralizing shell metacharacters. No authentication or user interaction is required, and successful exploitation can read or alter device data or interrupt router operation.
