This vulnerability allows an attacker to execute arbitrary code with root privileges or cause a DoS condition by sending a crafted HTTP request to the NX-API, posing a significant risk to the device's security and availability.
Exploitability
Exploitation requires sending a crafted HTTP request to the NX-API, which can be moderately difficult if the attacker has network access to the device.
Blast radius
If exploited, the vulnerability could result in complete control of the device by the attacker, leading to potential data loss, system compromise, and denial of service.

NVD description

A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device.  The vulnerability is due to insufficient input validation of data that is sent to the NX-API. An attacker could exploit this vulnerability by sending a crafted HTTP request to the NX-API of an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a reload of the device and a DoS condition.
