WellinTech created a fix that mitigates a remote code execution vulnerability and an information disclosure vulnerability in its KingSCADA, KingAlarm&Event, and KingGraphic applications, according to a report on ICS-CERT.

These remotely exploitable vulnerabilities first came to the attention of the Zero Day Initiative (ZDI) by security researcher Andrea Micalizzi.
