CVE-2021-1264

A vulnerability in the Command Runner tool of Cisco DNA Center could allow an authenticated, remote attacker to perform a command injection attack. The vulnerability is due to insufficient input validation by the Command Runner tool. An attacker could exploit this vulnerability by providing crafted input during command execution or via a crafted command runner API call. A successful exploit could allow the attacker to execute arbitrary CLI commands on devices managed by Cisco DNA Center.
