Low risk25th percentile - higher than 25% of all known CVEs
Summary
In Splunk SOAR versions below 8.6.0, an authenticated user with no role assigned could submit a crafted file path to the REST API and execute arbitrary code. The vulnerability exists because the REST API does not require an assigned role for the request and does not restrict the user-supplied file path to the intended temporary directory.
Risk Assessment
The risk includes the possibility of arbitrary code execution by an unprivileged user, potentially leading to system integrity and availability compromise.
Recommendation
It is recommended to upgrade Splunk SOAR to version 8.6.0 or later and enforce role-based access controls for the REST API.
