In Splunk Enterprise versions below 8.1.12, 8.2.9, and 9.0.2, Splunk Enterprise fails to properly validate and escape the Host header, which could let a remote authenticated user conduct various attacks against the system, including cross-site scripting and cache poisoning.
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
