The vulnerability could expose cleartext credentials from AVEVA InTouch Runtime 2020 R2 and all prior versions (WindowViewer) if an authorized, privileged user creates a diagnostic memory dump of the process and saves it to a non-protected location.

AVEVA InTouch 2014 R2 SP1 and prior, InTouch 2017, InTouch 2017 Update 1, and InTouch 2017 Update 2 allow an unauthenticated user to send a specially crafted packet that could overflow the buffer on a locale not using a dot floating point separator. Exploitation could allow remote code execution under the privileges of the InTouch View process.
