TITLE

Cisco FXOS and NX-OS In software NULL Pointer dereference vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-006583

DESCRIPTION

A vulnerability in the Cisco Fabric Services component of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the affected device. The vulnerability exists because the affected software insufficiently validates 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 force a NULL pointer dereference and 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: CSCvd69966, CSCve02435, CSCve04859, CSCve41590, CSCve41593, CSCve41601. Vendors have confirmed this vulnerability Bug ID CSCvd69966 , CSCve02435 , CSCve04859 , CSCve41590 , CSCve41593 ,and CSCve41601 It is released as.Service operation interruption (DoS) There is a possibility of being put into a state. Cisco Firepower 4100 Series Next-Generation Firewalls and so on are all products of Cisco. The Cisco Firepower 4100 Series Next-Generation Firewall is a 4100 series firewall device. MDS9000SeriesMultilayerSwitches is a switch device. FXOSSoftware is a suite of firewall software running on Cisco security appliances. NX-OSSoftware is a suite of data center-level operating system software running on Cisco switch devices. FabricServices is one of the Fabric service components
