Parameter Value
CVSS 7.6 (HIGH)
Affected Versions before 8.6.0
Fixed In 8.6.0
Type CWE-22 (Path Traversal)
Vendor Splunk
Public PoC No

In Splunk SOAR versions below 8.6.0, an authenticated user with no role assigned could submit a crafted file path to the Representational State Transfer (REST) API and execute arbitrary code. The vulnerability is possible 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. For more information see Manage roles and permissions in Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/manage-your-splunk-soar-on-premises-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-on-premises) and Splunk SOAR (On-premises) security information (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/introduction-to-splunk-soar-on-premises/splunk-soar-on-premises-security-information) in the Splunk documentation.
