Technical details
An OS command injection vulnerability (CWE-78) exists in the btool configuration helper component of the Splunk AI Toolkit. The flaw stems from an unsafe shell execution pattern where the application constructs OS command strings using dynamic parameters without properly disabling shell interpretation. An attacker with 'admin' role privileges can exploit this over the network to execute arbitrary commands on the Splunk Enterprise host. The vulnerability is resolved in version 5.7.4.
