Descriptions

A vulnerability in the Cisco Fabric Services component of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to execute arbitrary code or cause a denial of service (DoS) condition. The vulnerability exists because the affected software insufficiently validates header values in Cisco Fabric Services packets. An attacker could exploit this vulnerability by sending a crafted Cisco Fabric Services packet to an affected device. A successful exploit could allow the attacker to cause a buffer overflow that could allow the attacker to execute arbitrary code or cause a DoS condition. This vulnerability affects the following if configured to use Cisco Fabric Services: Firepower 4100 Series Next-Generation Firewalls, Firepower 9300 Security Appliance, MDS 9000 Series Multilayer Switches, Nexus 2000 Series Fabric Extenders, Nexus 3000 Series Switches, Nexus 3500 Platform Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches, Nexus 9000 Series Switches in standalone NX-OS mode, Nexus 9500 R-Series Line Cards and Fabric Modules, UCS 6100 Series Fabric Interconnects, UCS 6200 Series Fabric Interconnects, UCS 6300 Series Fabric Interconnects. Cisco Bug IDs: CSCvd69954, CSCve02463, CSCve02785, CSCve02787, CSCve02804, CSCve04859.

Una vulnerabilidad en el componente Cisco Fabric Services del software FXOS y Cisco NX-OS podría permitir que un atacante remoto no autenticado ejecute código arbitrario o cree una condición de denegación de servicio (DoS). La vulnerabilidad existe debido a que el software afectado no valida suficientemente los valores de las cabeceras de paquetes Cisco Fabric Services. Un atacante podría explotar esta vulnerabilidad enviando un paquete Cisco Fabric Services manipulado a un dispositivo afectado. Su explotación con éxito podría permitir que el atacante provoque un desbordamiento de búfer que le permitiría ejecutar código arbitrario o provocar una condición de denegación de servicio (DoS). Esta vulnerabilidad afecta a los siguientes productos si están configurados para emplear Cisco Fabric Services: Firepower 4100 Series Next-Generation Firewalls, Firepower 9300 Security Appliance, MDS 9000 Series Multilayer Switches, Nexus 2000 Series Fabric Extenders, Nexus 3000 Series Switches, Nexus 3500 Platform Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches, Nexus 9000 Series Switches en modo NX-OS independiente, Nexus 9500 R-Series Line Cards and Fabric Modules, UCS 6100 Series Fabric Interconnects, UCS 6200 Series Fabric Interconnects y UCS 6300 Series Fabric Interconnects. Cisco Bug IDs: CSCvd69954, CSCve02463, CSCve02785, CSCve02787, CSCve02804, CSCve04859.
