Risky Command Safeguards Bypass in “/app/search/search“ endpoint through “s“ parameter in Splunk Enterprise

In Splunk Enterprise versions below 9.3.3, 9.2.5, and 9.1.8 and Splunk Cloud Platform versions below 9.3.2408.103, 9.2.2406.108, 9.2.2403.113, 9.1.2312.208 and 9.1.2308.212, a low-privileged user that does not hold the “admin“ or “power“ Splunk roles could run a saved search with a risky command using the permissions of a higher-privileged user to bypass the SPL safeguards for risky commands on the “/app/search/search“ endpoint through its “s“ parameter. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The authenticated user should not be able to exploit the vulnerability at will.
