Name of the Vulnerable Software and Affected Versions Scheduler for TAS versions prior to 1.4.0

Description The issue allows plaintext transmission of a UAA client token over a non-TLS connection, which depends on the configuration of the MySQL server used to cache the token. If the token is intercepted, it can provide an attacker with admin-level access in the cloud controller.

Recommendations For versions prior to 1.4.0, update to version 1.4.0 or later to resolve the issue. As a temporary workaround, consider configuring the MySQL server to use a secure connection or restricting access to the UAA client token to minimize the risk of exploitation.
