Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.79%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

A vulnerability in specific REST API endpoints of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker to inject arbitrary commands on the underlying operating system with the privileges of the logged-in user. The vulnerability is due to insufficient validation of user-supplied input to the API. An attacker could exploit this vulnerability by sending a crafted request to the API. A successful exploit could allow the attacker to inject arbitrary commands on the underlying operating system.
