Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A vulnerability in the SIP processing subsystem of Cisco BroadWorks could allow an unauthenticated, remote attacker to halt the processing of incoming SIP requests, resulting in a denial of service (DoS) condition. This vulnerability is due to improper memory handling for certain SIP requests. An attacker could exploit this vulnerability by sending a high number of SIP requests to an affected system. A successful exploit could allow the attacker to exhaust the memory that was allocated to the Cisco BroadWorks Network Servers that handle SIP traffic. If no memory is available, the Network Servers can no longer process incoming requests, resulting in a DoS condition that requires manual intervention to recover.

         value: "Una vulnerabilidad en el subsistema de procesamiento SIP de Cisco BroadWorks podría permitir que un atacante remoto no autenticado detenga el procesamiento de solicitudes SIP entrantes, lo que da como resultado una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe a una gestión inadecuada de la memoria para ciertas solicitudes SIP. Un atacante podría aprovechar esta vulnerabilidad enviando una gran cantidad de solicitudes SIP a un sistema afectado. Una explotación exitosa podría permitir que el atacante agote la memoria asignada a los servidores de red Cisco BroadWorks que manejan el tráfico SIP. Si no hay memoria disponible, los servidores de red ya no pueden procesar solicitudes entrantes, lo que da como resultado una condición de DoS que requiere intervención manual para recuperarse.",
