AI risk analysis

Summary: This vulnerability allows an unauthenticated attacker to execute arbitrary code with root privileges or cause a Denial-of-Service (DoS) condition by sending crafted packets to an IP interface on an affected device.
Exploitability: Exploitation requires sending crafted packets to an enabled NGOAM feature, making it moderately hard to exploit.
Blast radius: If exploited, the vulnerability could result in arbitrary code execution and a DoS condition, impacting the availability and integrity of the device.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Disable the NGOAM feature or upgrade to the version 8.2(4) or later.

NVD description

A vulnerability in the VXLAN Operation, Administration, and Maintenance (OAM) feature of Cisco NX-OS Software, known as NGOAM, could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a Denial-of-Service (DoS) on an affected device. This vulnerability is due to improper input validation of IP traffic when the NGOAM feature is enabled. An attacker could exploit this vulnerability by sending crafted packets to an IP interface on an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes resulting in a reload and DoS condition.
