CVE-2024-8461Public exploitNetwork attack vector

Unauthenticated device metadata disclosure via discovery.cgi

Published Sep 5, 2024 · Updated Sep 5, 2024

Information disclosure in D-Link DNS-320 2.02b01 allows remote attackers to read device details through the web interface. The unauthenticated /cgi-bin/discovery.cgi endpoint accepts a POST request with an empty cmd value and returns the model, IP address, MAC address, firmware version, serial number, and configuration data. No login or user interaction is required, and the consequence is limited to disclosure of device and network metadata documented by the public proof of concept.
