Descriptions

A vulnerability in the XCP Router service of the Cisco Unified Communications Manager IM & Presence Service (CUCM IM&P) and the Cisco TelePresence Video Communication Server (VCS) and Expressway could allow an unauthenticated, remote attacker to cause a temporary service outage for all IM&P users, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a malicious IPv4 or IPv6 packet to an affected device on TCP port 7400. An exploit could allow the attacker to overread a buffer, resulting in a crash and restart of the XCP Router service. Cisco Bug IDs: CSCvg97663, CSCvi55947.

Una vulnerabilidad en el servicio XCP Router de Cisco Unified Communications Manager IM Presence Service (CUCM IMP) y Cisco TelePresence Video Communication Server (VCS) y Expressway podría permitir que un atacante remoto no autenticado provoque una caída temporal del servicio para todos los usuarios de IMP, lo que resulta en una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe a una validación incorrecta de las entradas proporcionadas por el usuario. Un atacante podría explotar esta vulnerabilidad enviando un paquete IPv4 o IPv6 malicioso al dispositivo afectado en el puerto TCP 7400. Su explotación con éxito podría permitir que el atacante sobrelea un búfer, resultando en un cierre inesperado y el reinicio del servicio XCP Router. Cisco Bug IDs: CSCvg97663, CSCvi55947.
