CVE-2025-34069

An authentication bypass vulnerability exists in GFI Kerio Control 9.4.5 due to insecure default proxy configuration and weak access control in the GFIAgent service. The non-transparent proxy on TCP port 3128 can be used to forward unauthenticated requests to internal services such as GFIAgent, bypassing firewall restrictions and exposing internal management endpoints. This enables unauthenticated attackers to access the GFIAgent service on ports 7995 and 7996, retrieve the appliance UUID, and issue administrative requests via the proxy. Exploitation results in full administrative access to the Kerio Control appliance.

Summary		(es) Existe una vulnerabilidad de omisión de autenticación en GFI Kerio Control 9.4.5 debido a una configuración de proxy predeterminada insegura y un control de acceso deficiente en el servicio GFIAgent. El proxy no transparente del puerto TCP 3128 puede utilizarse para reenviar solicitudes no autenticadas a servicios internos como GFIAgent, evadiendo las restricciones del firewall y exponiendo los endpoints de administración internos. Esto permite a atacantes no autenticados acceder al servicio GFIAgent en los puertos 7995 y 7996, recuperar el UUID del dispositivo y emitir solicitudes administrativas a través del proxy. Su explotación da como resultado acceso administrativo completo al dispositivo Kerio Control.
