Descriptions

Multiple vulnerabilities in the Java deserialization function that is used by Cisco Security Manager could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected device. These vulnerabilities are due to insecure deserialization of user-supplied content by the affected software. An attacker could exploit these vulnerabilities by sending a malicious serialized Java object to a specific listener on an affected system. A successful exploit could allow the attacker to execute arbitrary commands on the device with the privileges of NT AUTHORITY\SYSTEM on the Windows target host. Cisco has not released software updates that address these vulnerabilities.

Múltiples vulnerabilidades en la función de deserialización Java que es usada por Cisco Security Manager podrían permitir a un atacante remoto no autenticado ejecutar comandos arbitrarios en un dispositivo afectado. Estas vulnerabilidades son debido a una deserialización no segura del contenido suministrado por el usuario mediante el software afectado. Un atacante podría explotar estas vulnerabilidades mediante el envío de un objeto Java serializado malicioso hacia un oyente específico en un sistema afectado. Una explotación con éxito podría permitir al atacante ejecutar comandos arbitrarios en el dispositivo con los privilegios NT AUTHORITY\SYSTEM en el host de destino de Windows. Cisco no ha publicado actualizaciones de software que aborden estas vulnerabilidades
