Descriptions

A vulnerability in the web UI of Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. The vulnerability exists because the web UI does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. 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.

Una vulnerabilidad en la Interfaz de Usuario web de Cisco Unified Communications Manager (Unified CM) y Cisco Unified Communications Manager Session Management Edition (Unified CM SME) podría permitir a un atacante remoto no autenticado conducir un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz. La vulnerabilidad se presenta porque la Interfaz de Usuario web no comprueba apropiadamente la entrada suministrada por el usuario. Un atacante podría explotar esta vulnerabilidad al persuadir a un usuario de la interfaz para hacer click en un enlace diseñado. Una explotación con éxito podría permitir al atacante ejecutar un código de script arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en el navegador.
