Critical update advisories
There are three types of WPM player installs affected by this update advisory:
-
The default player installed on the main polling engine when OSH was first installed.
-
Remote players installed by the customer and configured for passive mode.
-
Remote players installed by the customer in active mode.
After upgrading, passive WPM Players installed by default on the main polling engine (using Server-initiated communication) are switched to the active mode (using Player-initiated communication).
Passive WPM Players installed remotely are pre-filled with a randomly generated strong password during their automatic upgrade. This includes WPM Players with a disabled "Enable Upgrade" toggle, these are not upgraded to the latest version.
Active WPM Players (using Player-initiated communication) do not require a password to be set after the upgrade.
