No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

DenyAll WAF before 6.4.1 allows unauthenticated remote attackers to obtain authentication information by making a typeOf=debug request to /webservices/download/index.php, and then reading the iToken field in the reply. This affects DenyAll i-Suite LTS 5.5.0 through 5.5.12, i-Suite 5.6, Web Application Firewall 5.7, and Web Application Firewall 6.x before 6.4.1, with On Premises or AWS/Azure cloud deployments.
