A vulnerability in the Cisco Fabric Services component of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to read sensitive memory content, create a denial of service (DoS) condition, or execute arbitrary code as root. 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. Cisco Bug IDs: CSCvd69951, CSCve02459, CSCve02461, CSCve02463, CSCve02474, CSCve04859.

Detection & IOCsextracted from sources · hover to see the quote
- →Detect crafted Cisco Fabric Services (CFS) packets with malformed/insufficient headers targeting FXOS and NX-OS devices — the exploit vector is a specially crafted CFS packet sent over the network to trigger buffer overflow or buffer overread in the CFS component. ↗
- →Monitor for unauthenticated remote traffic targeting the Cisco Fabric Services component on affected platforms (Firepower 4100/9300, MDS 9000, Nexus 2000/3000/3500/5500/5600/6000/7000/7700/9000/9500, UCS 6100/6200/6300) — exploitation requires no credentials. ↗
- →Alert on processes running as root on NX-OS/FXOS devices that were spawned unexpectedly — successful exploitation allows arbitrary code execution as root via the CFS component. ↗
- ·Vulnerability is only exploitable on devices configured to use Cisco Fabric Services (CFS). Scope of affected platforms is broad — verify CFS is enabled before prioritizing remediation. ↗
- ·There are no workarounds available for this vulnerability — patching is the only mitigation. ↗

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
