Descriptions
A vulnerability in the web-based management interface of Cisco AsyncOS for Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface of an affected device. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious data into a specific data field in an affected interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface.
Una vulnerabilidad en la interfaz de administración basada en web de Cisco AsyncOS para Cisco Web Security Appliance (WSA), podría permitir a un atacante remoto autenticado conducir un ataque de tipo cross-site scripting (XSS) almacenado contra un usuario de la interfaz de un dispositivo afectado. La vulnerabilidad se presenta porque la interfaz de administración basada en web no comprueba apropiadamente la entrada suministrada por el usuario. Un atacante podría explotar esta vulnerabilidad insertando datos maliciosos en un campo de datos específico en una interfaz afectada. Una explotación con éxito podría permitir al atacante ejecutar código de script arbitrario en el contexto de la interfaz afectada
