Cleartext Submission of Password

Cleartext Submission of Password

With our recent PCI audit it has been discovered that our version of ADManager Plus has a vulnerability with Cleartext Submission of Password. We are currently on version 6.6.5 Build 6659.

Is there a way to stop the submission of cleartext passwords?
