Splunk: CVE-2024-36985: Remote Code Execution (RCE) through an external lookup due to “copybuckets.py“ script in the “splunk_archiver“ application in Splunk Enterprise

In Splunk Enterprise versions below 9.0.10, 9.1.5, and 9.2.2, a low-privileged user that does not hold the “admin“ or “power“ Splunk roles could cause a Remote Code Execution through an external lookup that likely references the “splunk_archiver“ application.The “splunk_archiver“ application likely contains a script called “copybuckets.py“ that itself references a file called “erp_launcher.py“, which would likely execute a script called “sudobash“.The “sudobash“ script does not perform any input checking. Therefore it runs a bash shell with arguments supplied by the “erp_launcher.py“ file. This can lead to an RCE.
