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 on an affected device. The vulnerability exists because the affected software insufficiently validates Cisco Fabric Services packet headers when the software processes packet data. An attacker could exploit this vulnerability by sending a maliciously crafted Cisco Fabric Services packet to an affected device. A successful exploit could allow the attacker to cause a buffer overflow condition on the device, which could allow the attacker to execute arbitrary code or cause a DoS condition on the device. 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: CSCvd69962, CSCve02808, CSCve02810, CSCve02812, CSCve02819, CSCve02822, CSCve02831, CSCve04859.

Detection & IOCsextracted from sources · hover to see the quote
- →Detect maliciously crafted Cisco Fabric Services (CFS) packets targeting the CFS packet header parsing code path; look for anomalous or oversized CFS packet headers that could trigger a buffer overflow condition on FXOS/NX-OS devices ↗
- →Monitor for unexpected remote connections or traffic patterns targeting devices configured to use Cisco Fabric Services (CFS); the attack vector is network-based and requires no authentication, so any unauthenticated CFS traffic from external/untrusted sources is suspicious ↗
- →Scope detection to the following affected platforms when CFS is enabled: Firepower 4100 Series, Firepower 9300, MDS 9000, Nexus 2000/3000/3500/5500/5600/6000/7000/7700/9000/9500, UCS 6100/6200/6300 Fabric Interconnects running FXOS or NX-OS ↗
- ·Vulnerability is only exploitable on devices that are configured to use Cisco Fabric Services (CFS); devices not using CFS are not affected ↗
- ·There are no workarounds available for this vulnerability; patching via Cisco software updates is the only remediation ↗
- ·Multiple Cisco Bug IDs are tracked for this single CVE across different affected platforms: CSCvd69962, CSCve02808, CSCve02810, CSCve02812, CSCve02819, CSCve02822, CSCve02831, 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
