Descriptions

A vulnerability in Java deserialization used by Cisco Secure Access Control System (ACS) prior to release 5.8 patch 9 could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected device. The vulnerability is due to insecure deserialization of user-supplied content by the affected software. An attacker could exploit this vulnerability by sending a crafted serialized Java object. An exploit could allow the attacker to execute arbitrary commands on the device with root privileges. Cisco Bug IDs: CSCvh25988.

Una vulnerabilidad en la deserialización de Java utilizada por Cisco Secure Access Control System (ACS) en versiones anteriores a la 5.8, parche 9, podría permitir que un atacante remoto no autenticado ejecute comandos arbitrarios en un dispositivo afectado. La vulnerabilidad se debe a la deserialización no segura por parte del software afectado de contenidos proporcionados por el usuario. Un atacante podría explotar esta vulnerabilidad enviando un objeto Java serializado manipulado. Su explotación podría permitir que el atacante ejecute comandos arbitrarios en el dispositivo con privilegios root. Cisco Bug IDs: CSCvh25988.
