Splunk Enterprise 8.1.x < 8.1.7 Information Disclosure

medium Nessus Plugin ID 163933


An application running on a remote web server host may be affected by an information disclosure vulnerability.


The Splunk Enterprise REST API allows enumeration of usernames via the lockout error message. The potential vulnerability impacts Splunk Enterprise instances before 8.1.7 when configured to return verbose login errors.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade Splunk Enterprise to version 8.1.7, or later.
