Descriptions

A vulnerability has been identified in SINUMERIK 808D V4.7 (All versions), SINUMERIK 808D V4.8 (All versions), 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). A local attacker could modify a user-writeable configuration file so that after reboot or manual initiation the system reloads the modified configuration file and attacker-controlled code is executed with elevated privileges. The security vulnerability could be exploited by an attacker with local access to the affected system. Successful exploitation requires user privileges but no user interaction. The vulnerability could allow an attacker to compromise confidentiality, integrity and availability of the system. At the time of advisory publication no public exploitation of this security vulnerability was known.

Se ha identificado una vulnerabilidad en SINUMERIK 808D V4.7 (todas las versiones), SINUMERIK 808D V4.8 (todas las versiones), 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). Un atacante local podría modificar un archivo de configuración modificable por un usuario para que, tras el reinicio o inicio manual, el sistema recargue el archivo de configuración modificado y se ejecute código controlado por el atacante con privilegios elevados. Esta vulnerabilidad de seguridad podría ser explotada por atacantes con acceso local al sistema afectado. Su explotación con éxito requiere privilegios de usuario, pero no requiere interacción del usuario. Esta vulnerabilidad podría permitir que un atacante comprometa la confidencialidad, integridad y disponibilidad del sistema. En el momento de la publicación del advisory, no se conoce ninguna explotación pública de la vulnerabilidad de seguridad.
