Splunk
Parameter Value
CVSS 6.5 (MEDIUM)
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, a user who holds the Administrator role could use path traversal in the Universal Forwarder installer's archive extraction to write files outside the intended installation directory. The vulnerability is possible because the Universal Forwarder credentials-package extraction workflow does not verify that each archive member remains within the intended destination before extraction. 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 Configure forwarders to send SOAR data to your Splunk deployment (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/configure-administration-settings-in-splunk-soar-on-premises/configure-forwarders-to-send-soar-data-to-your-splunk-deployment) in the Splunk documentation.
