Description
In Splunk SOAR versions below 8.6.0, a user who holds the OnPrem Broker role could write files outside the intended Automation Broker log directory. The vulnerability is possible because Automation Broker log uploads accept crafted filename input before writing log files. For more information see Manage roles and permissions in Splunk SOAR (Cloud) (https://help.splunk.com/en/splunk-soar/soar-cloud/administer-soar-cloud/manage-your-splunk-soar-cloud-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-cloud) and About Splunk SOAR Automation Broker (https://help.splunk.com/en/splunk-soar/splunk-automation-broker/about-splunk-soar-automation-broker/about-splunk-soar-automation-broker) in the Splunk documentation.
