Vulnerability Details
InduSoft Web Studio and InTouch Machine Edition provide the capability for an HMI client to read, write tags and monitor alarms and events. A remote malicious entity 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. The code would be executed under high privileges and could lead to a complete compromise of the InduSoft Web Studio or InTouch Machine Edition server machine.
