Title
Scheduler for TAS can transmit privileged UAA token in plaintext
Summary
Scheduler for TAS prior to version 1.4.0 was permitting plaintext transmission of UAA client token by sending it over a non-TLS connection. This also depended on the configuration of the MySQL server which is used to cache a UAA client token used by the service. If intercepted the token can give an attacker admin level access in the cloud controller.
