CVE-2023-48842Public exploitNetwork attack vector

Unauthenticated command execution via service parameter

Published Dec 1, 2023 · Updated Jun 3, 2025

Command injection in D-Link Go-RT-AC750 firmware 101b03 allows remote attackers to execute arbitrary commands through hedwig.cgi. Public records identify the service XML parameter but do not disclose the command-building operation that mishandles its value. An unauthenticated network request is sufficient; successful exploitation executes attacker-selected commands on the router.
