CVE-2023-53974Public exploitNetwork attack vector

Configuration disclosure via unauthenticated backup request

Published Dec 22, 2025 · Updated Dec 22, 2025

Information disclosure in D-Link DSL-124 ME_1.00 allows remote attackers to retrieve router settings through an unauthenticated POST request. The form2saveConf.cgi handler processes a crafted save-configuration form submission without verifying an authenticated management session. Network access to the management interface is sufficient to download config.img, exposing wireless pre-shared keys and other router configuration data.
