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.

mappy.py in Splunk Web in Splunk 4.2.x before 4.2.5 does not properly restrict use of the mappy command to access Python classes, which allows remote authenticated administrators to execute arbitrary code by leveraging the sys module in a request to the search application, as demonstrated by a cross-site request forgery (CSRF) attack, aka SPL-45172.

Cross-site scripting (XSS) vulnerability in Splunk Web in Splunk 4.2.x before 4.2.5 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, aka SPL-44614.

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.
