Summary

In Splunk Enterprise for Windows versions below 10.4.2, 10.2.6, 10.0.9, 9.4.13, and 9.3.14, a local user with access to the Windows host could bind to the management port before Splunk Enterprise starts, intercept authentication tokens from child processes, and use those tokens to compromise all relevant data and system integrity available to the user account running Splunk Enterprise. The vulnerability is possible because the Windows management-port listener does not apply exclusive address binding protections before the service starts.
