Descriptions

A vulnerability in the web-based management interface of Cisco Jabber Guest could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability exists because the web-based management interface of the affected device does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or to access sensitive, browser-based information. This vulnerability affects Cisco Jabber Guest releases 11.1(2) and earlier.

Una vulnerabilidad en la interfaz de administración basada en web de Cisco Jabber Guest podría permitir que un atacante remoto no autenticado realice un ataque de scripting entre sitios (XSS) contra un usuario de la interfaz de administración basada en web de un dispositivo afectado. La vulnerabilidad existe porque la interfaz de administración basada en web del dispositivo afectado no valida correctamente la entrada proporcionada por el usuario. Un atacante podría aprovechar esta vulnerabilidad persuadiendo a un usuario para que haga clic en un enlace malicioso. Una explotación con éxito podría permitir al atacante ejecutar código de script arbitrario en el contexto de la interfaz afectada o acceder a información confidencial basada en el navegador. Esta vulnerabilidad afecta a las versiones 11.1 (2) y anteriores de Cisco Jabber Guest.
