CVE-2022-37056Known exploitationPublic exploitNetwork attack vector

Unauthenticated command execution via HNAP SOAPAction

Published Aug 28, 2022 · Updated Jan 9, 2025

OS command injection in D-Link GO-RT-AC750 firmware 1.01b03 and 2.00b02 allows remote attackers to execute arbitrary commands. The /cgibin hnap_main handler incorporates the HNAP SOAPAction value into a system shell command without adequate neutralization. No authentication or user interaction is required, so a network-reachable HNAP interface exposes the router to full command execution.
