Information Disclosure through Action Parameters in Cisco Webex app for Splunk SOAR
Source: CVE Program / CVE List V5
Vulnerability Description
In versions below 2.2.1 of the Cisco Webex app for Splunk SOAR, a user who holds a role with permission to run actions could expose a sensitive meeting password by invoking the schedule meeting action, because the action's password 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.
