| Description | In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who holds the "power" Splunk role could store attacker-controlled Search Processing Language (SPL) in a Table Editor dataset and share the dataset. A user who holds the "admin" Splunk role triggers the SPL when that user opens the dataset in the Table Editor. The SPL runs using the permissions of the second user and could expose all relevant data and modify limited data on the search head. The vulnerability is possible because the Table Editor does not apply SPL safeguards for risky commands when it prepares the dataset initial data. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The user who holds the "power" Splunk role should not be able to exploit the vulnerability at will.
