CVE-2020-5426

9.8 criticalEPSS 0.7%

Critical (9.8) in vmware pivotal scheduler. EPSS 0.7% chance of exploitation in the next 30 days.

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.
