Descriptions

A vulnerability in the web-based UI of Cisco Secure Access Control Server could allow an authenticated, remote attacker to gain read access to certain information in an affected system. The vulnerability is due to improper handling of XML External Entities (XXEs) when parsing an XML file. An attacker could exploit this vulnerability by convincing the administrator of an affected system to import a crafted XML file.

Una vulnerabilidad en la interfaz web de usuario de Cisco Secure Access Control Server podría permitir que un atacante remoto autenticado obtenga acceso de lectura a determinada información en un sistema afectado. La vulnerabilidad se debe a una gestión incorrecta de XXE (Entidades Externas XML) a la hora de analizar sintácticamente un archivo XML. Un atacante podría explotar esta vulnerabilidad convenciendo al administrador de un sistema afectado para que importe un archivo XML manipulado.
