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 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. The security vulnerability could be exploited by an attacker with network access to the affected devices on port 4842/tcp. Successful exploitation requires no privileges and no user interaction. The vulnerability could allow an attacker to compromise confidentiality, integrity and availability of the web 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 web integrado en el puerto 4842/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 4842/tcp. 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. En el momento de la publicación del advisory, no se conoce ninguna explotación pública de la vulnerabilidad de seguridad.
