Summary
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user could trick a user who holds the "admin" Splunk role into opening a crafted link to Monitoring Console. When that user opens the link, Splunk Enterprise runs attacker-controlled Search Processing Language (SPL) using the permissions of that user. The injected SPL could expose data available to that user or modify lookup data. The vulnerability is possible because Monitoring Console does not sufficiently validate data used to build dashboard searches. The vulnerability requires the attacker to phish the user by tricking them into opening the crafted link. The unauthenticated user should not be able to exploit the vulnerability at will.
