Summary

• A vulnerability in the implementation of the Cisco Network Plug-and-Play (PnP) agent of Cisco DNA Center could allow an authenticated, remote attacker to view sensitive information in clear text. The attacker must have valid low-privileged user credentials.

  This vulnerability is due to improper role-based access control (RBAC) with the integration of PnP. An attacker could exploit this vulnerability by authenticating to the device and sending a query to an internal API. A successful exploit could allow the attacker to view sensitive information in clear text, which could include configuration files.

  Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
