CVE-2018-11457

Estado: ModificadaAlta (8.1)—

A vulnerability has been identified in SINUMERIK 828D V4.7 (All versions < V4.7 SP6 HF1), SINUMERIK 840D sl V4.7 (All versions < V4.7 SP6 HF5), SINUMERIK 840D sl V4.8 (All versions < V4.8 SP3). The integrated web server on port 4842/tcp of the affected products could allow a remote attacker to execute code with privileged permissions on the system by sending specially crafted network requests to port 4842/tcp. Please note that this vulnerability is only exploitable if port 4842/tcp is manually opened in the firewall configuration of network port X130.

Leer descripción completaMostrar menos

Nótese que esta vulnerabilidad solo puede explotarse si el puerto 4842/tcp se abre manualmente en la configuración de firewall del puerto de red X130. La vulnerabilidad de seguridad podría ser explotada por atacantes con acceso de red a los sistemas afectados en el puerto 4842/tcp. Su explotación con éxito no requiere privilegios de usuario ni interacción. Esta vulnerabilidad podría permitir que un atacante comprometa la confidencialidad, integridad y disponibilidad del servidor web.
