CVE-2024-33112Known exploitationPublic exploitNetwork attack vector

Unauthenticated command execution via HNAP SOAPAction

Published May 6, 2024 · Updated Jan 7, 2025

OS command injection in D-Link DIR-845L 1.01KRb03 and earlier allows remote attackers to execute commands through HNAP requests. The hnap_main function accepts a SOAPAction containing the GetDeviceSettings URI, then treats trailing action text as a shell command without neutralizing metacharacters. The unauthenticated proof of concept writes a file and starts a telnet service, while published impact evidence does not establish data disclosure.
