Descriptions
A vulnerability in the Interactive Voice Response (IVR) management connection interface for Cisco Unified Customer Voice Portal (CVP) could allow an unauthenticated, remote attacker to cause the IVR connection to disconnect, creating a system-wide denial of service (DoS) condition. The vulnerability is due to improper handling of a TCP connection request when the IVR connection is already established. An attacker could exploit this vulnerability by initiating a crafted connection to the IP address of the targeted CVP device. An exploit could allow the attacker to disconnect the IVR to CVP connection, creating a DoS condition that prevents the CVP from accepting new, incoming calls while the IVR automatically attempts to re-establish the connection to the CVP. This vulnerability affects Cisco Unified Customer Voice Portal (CVP) Software Release 11.5(1). Cisco Bug IDs: CSCve70560.
Una vulnerabilidad en la interfaz de gestión de conexión IVR (Interactive Voice Response) para Cisco Unified Customer Voice Portal (CVP) podría permitir que un atacante remoto no autenticado provoque que la conexión IVR se desconecte, creando una condición de denegación de servicio (DoS) en todo el sistema. La vulnerabilidad se debe a la gestión inadecuada de una petición de conexión TCP cuando ya se ha establecido una conexión IVR. Un atacante podría explotar esta vulnerabilidad iniciando una conexión manipulada a la dirección IP local del dispositivo CVP objetivo. Una explotación podría permitir que el atacante desconecte la conexión IVR a CVP, creando una condición de denegación de servicio (DoS) que evita que el CVP acepte nuevas llamadas entrantes mientras el IVR intenta restablecer de forma automática la conexión al CVP. Esta vulnerabilidad afecta a la versión 11.5(1) del software que ejecute Cisco Unified Customer Voice Portal (CVP). Cisco Bug IDs: CSCve70560.
