Path Traversal through App Installation Tar Extraction in Splunk SOAR

AI Analysis

No AI analysis yet.

Description

In Splunk SOAR versions below 8.6.0, a user with app-install privileges could use path traversal during app installation to write files outside the intended temporary directory. The vulnerability is a path traversal in the archive extraction routine, which does not validate that extracted file paths stay within the intended destination 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 Add and configure apps and assets to provide actions 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-apps-and-assets/add-and-configure-apps-and-assets-to-provide-actions-in-splunk-soar-on-premises) in the Splunk documentation.
