CVE-2023-7308Known exploitationPublic exploitNetwork attack vector

Information disclosure via unauthenticated user-data POST

Published Aug 27, 2025 · Updated Nov 28, 2025

Missing authentication in NSFOCUS SecGate3600 Firewall allows remote attackers to read user identifiers and configuration details. The /cgi-bin/authUser/authManageSet.cgi handler processes a type=getAllUsers POST request without enforcing authentication and returns stored user data. Network access to the management endpoint is sufficient; the demonstrated consequence is disclosure of user identifiers and configuration details.
