Descriptions

A vulnerability in the User Data Services (UDS) API of Cisco Unified Communications Manager (Unified CM) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the management GUI. The vulnerability is due to improper validation of input parameters in the UDS API requests. An attacker could exploit this vulnerability by sending a crafted request to the UDS API of an affected device. A successful exploit could allow the attacker to make the A Cisco DB service quit unexpectedly, preventing admin access to the Unified CM management GUI. Manual intervention may be required to restore normal operation. Software versions 10.5, 11.5, 12.0, 12.5 are affected.

Una vulnerabilidad en la API de servicios de datos de usuario (UDS) de Unified Communications Manager (Unified CM) de Cisco podría permitir que un atacante remoto no autenticado cause una condición de denegación de servicio (DoS) en la GUI de administración. La vulnerabilidad es debido a la comprobación inapropiada de los parámetros de entrada en las peticiones de la API de UDS. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición creada a la API de UDS de un dispositivo afectado. Una explotación con éxito podría permitir al atacante hacer que el servicio A Cisco DB se cierre inesperadamente, impidiendo el acceso del administrador a la GUI de administración del Unified CM Puede requerirse intervención manual para restablecer el funcionamiento normal. Las versiones de software 10.5, 11.5, 12.0, 12.5 están impactadas
