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.

AVEVA InduSoft Web Studio v8.1 and v8.1SP1, and InTouch Machine Edition v2017 8.1 and v2017 8.1 SP1 a remote user could send a carefully crafted packet to exploit a stack-based buffer overflow vulnerability during tag, alarm, or event related actions such as read and write, with potential for code to be executed.

A remote attacker could send a carefully crafted packet in InduSoft Web Studio v8.1 and prior versions, and/or InTouch Machine Edition 2017 v8.1 and prior versions during a tag, alarm, or event related action such as read and write, which may allow remote code execution.
