The vulnerability is due to incomplete validation of SCTP packets being monitored on the NGA data ports. An attacker could exploit this vulnerability by sending malformed SCTP packets on a network that is monitored by an NGA data port. SCTP packets addressed to the IP address of the NGA itself will not trigger this vulnerability. An exploit could allow the attacker to cause the appliance to become unresponsive or reload, causing a DoS condition. User interaction could be needed to recover the device using the reboot command from the CLI. The following Cisco NetFlow Generation Appliances are vulnerable: NGA 3140, NGA 3240, NGA 3340. Cisco Bug IDs: CSCvc83320."},{"lang":"es","value":"Una vulnerabilidad en el decodificador Stream Control Transmission Protocol (SCTP) de Cisco NetFlow Generation Appliance (NGA) con software anterior a 1.1 (1a) podría permitir a un atacante remoto no autenticado hacer que el dispositivo se bloquee o se vuelva a cargar inesperadamente, provocando una condición de denegación de servicio (DoS). La vulnerabilidad se debe a validación incompleta de los paquetes SCTP que se supervisan en los puertos de datos NGA. Un atacante podría explotar esta vulnerabilidad enviando paquetes SCTP malformados en una red supervisada por un puerto de datos NGA. Los paquetes SCTP dirigidos a la dirección IP de la propia NGA no desencadenarán esta vulnerabilidad. Un exploit podría permitir al atacante hacer que el aparato no respondiera o se volviera a cargar, provocando una condición DoS. La interacción del usuario podría ser necesaria para recuperar el dispositivo utilizando el comando de reinicio de la CLI.
