Severity ?
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
CWE
  • CWE-862 - The software does not perform an authorization check when an actor attempts to access a resource or perform an action.
Summary
In Splunk SOAR versions below 8.7.0, an authenticated user who does not hold a role with permission to edit Automation Brokers could download the Splunk SOAR Automation Broker Docker Compose configuration file. The file contains the Uniform Resource Locator (URL) of the Splunk SOAR instance, the container image location, and the Splunk SOAR Automation Broker version. The vulnerability is possible because Splunk SOAR returns the configuration file without enforcing the Automation Broker edit permission. For more information see Install Splunk Automation Broker on a Docker host (https://help.splunk.com/en/splunk-soar/splunk-automation-broker/install-and-create-classic-splunk-soar-automation-brokers/install-splunk-automation-broker-on-a-docker-host) and 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) in the Splunk documentation.
