Title

Cisco DNA Center Privilege Escalation Vulnerability

Summary

A vulnerability in the user management roles of Cisco DNA Center could allow an authenticated, remote attacker to execute unauthorized commands on an affected device. The vulnerability is due to improper enforcement of actions for assigned user roles. An attacker could exploit this vulnerability by authenticating as a user with an Observer role and executing commands on the affected device. A successful exploit could allow a user with the Observer role to execute commands to view diagnostic information of the devices that Cisco DNA Center manages.
