The XML parser in Splunk 4.0.0 through 4.1.4 allows remote authenticated users to obtain sensitive information and gain privileges via an XML External Entity (XXE) attack to unknown vectors.

Cross-site scripting (XSS) vulnerability in Splunk 4.0 through 4.1.2, when Internet Explorer is used, allows remote attackers to inject arbitrary web script or HTML via the HTTP Referer in a "404 Not Found" response.

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.

Multiple directory traversal vulnerabilities in Splunk 4.x before 4.2.5 allow remote authenticated users to read arbitrary files via a .. (dot dot) in a URI to (1) Splunk Web or (2) the Splunkd HTTP Server, aka SPL-45243.
