Vulnerability Data

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…

more

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Enforces secure configuration management, reducing the risk of plaintext secrets being stored in application config files.

degrades

Requires secure handling and storage of authentication credentials, directly addressing plaintext passwords in config files.

mitigates

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.

mitigates

Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.

mitigates

Secure deletion of obsolete or temporary copies prevents sensitive data from remaining in cleartext on disk after its intended lifetime.

A.8.11 Data masking partial match
mitigates

Substituting real values with hashes or encrypted tokens before storage reduces the quantity of cleartext sensitive information that ends up persisted on disk.
