CWE-555Published: March 23, 2023· Updated: Jun 17, 2026
Official Description
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.
Technical Analysis
CVE-2023-20059 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 6.5.
