Descriptions

A vulnerability in the web framework of Cisco WebEx Meetings Server could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web interface of an affected system. The vulnerability is due to insufficient input validation of some parameters that are passed to the web server of the affected system. An attacker could exploit this vulnerability by convincing a user to follow a malicious link or by intercepting a user request and injecting malicious code into the request. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected web interface or allow the attacker to access sensitive browser-based information. Cisco Bug IDs: CSCve96608.

Una vulnerabilidad en el framework web de Cisco WebEx Meetings Server podría permitir que un atacante remoto sin autenticar lleve a cabo un ataque de Cross-Site Scripting (XSS) contra un usuario de dicha interfaz en un sistema afectado. La vulnerabilidad se debe a una validación de entrada insuficiente de algunos parámetros que se pasan al servidor web del sistema afectado. Un atacante podría explotar esta vulnerabilidad convenciendo a un usuario de que entre a un enlace malicioso o interceptando una petición de usuario e inyectando código malicioso en la petición. Si se explota esta vulnerabilidad con éxito, el atacante podría ejecutar código de script arbitrario en el contexto de la interfaz web afectada o permitir que el atacante pueda acceder a información confidencial del navegador. Cisco Bug IDs: CSCve96608.
