In versions below 2.1.9 of the AWS IAM app for Splunk SOAR, a user who holds a role with permission to run actions could expose sensitive AWS credentials by invoking an action that accepts the credentials parameter, because the parameter is not masked and is shown in cleartext in the user interface. The information disclosure is possible because the app does not mark the affected action parameter as a password. For more information see Run an action in Splunk SOAR (https://help.splunk.com/en/splunk-soar/soar-on-premises/use-splunk-soar-on-premises/8.6.0/use-the-command-line-interface-to-perform-tasks-in-splunk-soar-on-premises/run-an-action-in-splunk-soar-on-premises).
Turn off or remove the AWS IAM app for Splunk SOAR. For more information see Add and configure apps and assets to provide actions in Splunk SOAR in the Splunk documentation. Note: Turning off the app stops all actions configured through it from running.
Upgrade each affected Splunk SOAR connector to the applicable fixed version listed in Product Status.
The fixed app version requires Splunk SOAR 8.6.0 or higher.
