Teradici PCoIP Management Console versions 20.01.0 and 19.11.1 are vulnerable to unauthenticated password resets of the default admin account. This vulnerability only exists when the default admin account is not disabled.
The affected Management Console releases allow unauthenticated user access to the Management Console

- PCoIP Management Console version 20.01.0
- PCoIP Management Console version 19.11.1
Teradici released PCoIP Management Console 20.01.1 and 19.11.2 on March 5th to address this vulnerability and notified all customers of the Management Console.
