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.

Cisco released a high-severity patch update for CVE-2018-0296 on June 22 which affects the Adaptive Security Appliance (ASA). There’s no time to waste in deploying this patch, as the company’s advisory notes it is currently being exploited in the wild.
The ASA patch, which addresses the lack of proper input validation of the HTTP URL, is the latest in a long list of updates from Cisco this month. A slew of patches were issued June 6, followed by a whopping 34 patches on June 20, including five critical and 19 high-severity patches for its Firepower firewalls (FXOS) and Nexus switches (NX-OS). Another 10 medium-severity fixes also were i
