Splunk 4.2.5 and earlier, when a Free license is selected, enables potentially undesirable functionality within an environment that intentionally does not support authentication, which allows remote attackers to (1) read arbitrary files via a management-console session that leverages the ability to create crafted data sources, or (2) execute management commands via an HTTP request.
Weakness
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
