Descriptions

A vulnerability in the web-based management interface of Cisco Prime Access Registrar could allow an authenticated, remote attacker to perform a stored cross-site scripting attack on an affected system. This vulnerability exists because the web-based management interface does not sufficiently validate user-supplied input. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker would need valid administrative credentials. Cisco expects to release software updates that address this vulnerability.

Una vulnerabilidad en la interfaz de administración basada en la web de Cisco Prime Access Registrar podría permitir a un atacante remoto y autenticado llevar a cabo un ataque de tipo cross-site scripting almacenado en un sistema afectado. Esta vulnerabilidad es debido a que la interfaz de administración basada en la web no comprueba suficientemente la información proporcionada por el usuario. Un atacante podría explotar esta vulnerabilidad al inyectar código malicioso en páginas específicas de la interfaz. Una explotación con éxito podría permitir al atacante ejecutar código script arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en el navegador. Para explotar esta vulnerabilidad, el atacante necesitaría credenciales administrativas válidas. Cisco espera publicar actualizaciones de software que aborden esta vulnerabilidad
