Descriptions

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 VNC server on port 5900/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 5900/tcp. Please note that this vulnerability is only exploitable if port 5900/tcp is manually opened in the firewall configuration of network port X130. The security vulnerability could be exploited by an attacker with network access to the affected devices and port. Successful exploitation requires no privileges and no user interaction. The vulnerability could allow an attacker to compromise confidentiality, integrity and availability of the VNC server. At the time of advisory publication no public exploitation of this security vulnerability was known.

Se ha identificado una vulnerabilidad en SINUMERIK 828D V4.7 (todas las versiones anteriores a la V4.7 SP6 HF1), SINUMERIK 840D sl V4.7 (todas las versiones anteriores a la V4.7 SP6 HF5) y SINUMERIK 840D sl V4.8 (todas las versiones anteriores a la V4.8 SP3). El servidor VNC integrado en el puerto 5900/tcp de los productos afectados podría permitir que un atacante remoto ejecute código con permisos privilegiados en el sistema mediante el envío de peticiones de web especialmente manipuladas al puerto 5900/tcp. Nótese que esta vulnerabilidad solo puede explotarse si el puerto 5900/tcp se abre manualmente en la configuración de firewall del puerto de red X130. Esta vulnerabilidad podría ser explotada por atacantes con acceso a los sistemas y puertos afectados. 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 VNC. En el momento de la publicación del advisory, no se conoce ninguna explotación pública de la vulnerabilidad de seguridad.
