The vulnerability exists because the affected software insufficiently validates Cisco Fabric Services packet headers. 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 or buffer overread condition in the Cisco Fabric Services component, which could allow the attacker to read sensitive memory content, create a DoS condition, or execute arbitrary code as root. 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.

La vulnerabilidad existe debido a que el software afectado no valida suficientemente las cabeceras de paquetes Cisco Fabric Services. Un atacante podr\u00eda explotar esta vulnerabilidad enviando un paquete Cisco Fabric Services manipulado a un dispositivo afectado. Su explotaci\u00f3n con \u00e9xito podr\u00eda permitir que el atacante provoque un desbordamiento o una sobrelectura de b\u00fafer en el componente Cisco Fabric Services, lo que podr\u00eda permitir que el atacante lea contenido sensible de la memoria, cree una condici\u00f3n de denegaci\u00f3n de servicio (DoS) o ejecute c\u00f3digo arbitrario como root.
