Unauthenticated device details disclosure via info.cgi

Published Apr 4, 2024 · Updated Aug 26, 2024

Information disclosure in D-Link DNS-320L, DNS-320LW, and DNS-327L 20240403 and earlier allows remote attackers to read device details via HTTP. The unauthenticated /cgi-bin/info.cgi handler returns the device vendor, model, and firmware version for any HTTP GET request. No credentials or user interaction are required; exposure is limited to device-identifying and firmware data that supports follow-on targeting.
