Title
OS Command Injection in the btool Configuration Helper in Splunk AI Toolkit
Summary
In Splunk AI Toolkit versions below 5.7.4, a user who holds the "admin" Splunk role could execute arbitrary OS commands on the host running the Splunk Enterprise instance.
The vulnerability is possible because of an unsafe shell execution pattern in the btool configuration helper, which constructs OS command strings from dynamic parameters without disabling shell interpretation.
Severity

CWE
- CWE-78 - The software constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
