Network UPS Tools Cleartext Authentication

medium Nessus Plugin ID 59659
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The UPS monitoring tool on the remote host does not support encrypted authentication.


The remote Network UPS Tools does not support exchanging credentials through an encrypted channel. An unauthenticated, remote attacker can exploit this to perform a man-in-the-middle attack, intercept credentials, and alter the settings on the UPS that the server manages.


Enable StartTLS support on the server using the 'CERTFILE' directive.
