Descriptions

A vulnerability in the Session Initiation Protocol (SIP) UDP throttling process of Cisco Unified Communications Manager (Cisco Unified CM) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient rate limiting protection. An attacker could exploit this vulnerability by sending the affected device a high rate of SIP messages. An exploit could allow the attacker to cause the device to reload unexpectedly. The device and services will restart automatically. This vulnerability affects Cisco Unified Communications Manager (CallManager) releases prior to the first fixed release; the following list indicates the first minor release that includes the fix for this vulnerability: 10.5.2.14900-16 11.0.1.23900-5 11.5.1.12900-2. Cisco Bug IDs: CSCuz72455.

La vulnerabilidad se debe a una protección insuficiente de la tasa de limitación. Un atacante podría explotar esta vulnerabilidad enviando al dispositivo afectado una alta tasa de mensajes SIP. Un exploit podría permitir al atacante hacer que el dispositivo se recargue inesperadamente. El dispositivo y los servicios se reiniciarán automáticamente. Esta vulnerabilidad afecta a las versiones de Cisco Unified Communications Manager (CallManager) This vulnerability affects Cisco Unified Communications Manager (CallManager) anteriores a la primera versión fija; la siguiente lista indica la primera versión secundaria que incluye la corrección para esta vulnerabilidad: 10.5.2.14900-16 11.0.1.23900-5 11.5.1.12900-2.
