CVE-2024-11494Public exploitNetwork attack vector

Unauthenticated device-information disclosure via HTTP HEAD

Published Nov 20, 2024 · Updated Nov 20, 2024

Improper authentication in Zyxel P-6101C firmware P-6101CSA6AP_20140331 allows remote attackers to read device information. The web interface handles HEAD requests to protected CGI paths without enforcing the authentication check applied to ordinary requests. A network-reachable attacker needs no credentials and can retrieve status_deviceinfo.asp content, exposing device details without changing data or interrupting service.
