Summary
Schneider Electric IGSS Definition module contains a vulnerability (CWE-787) that allows arbitrary code execution through a malicious file. The IGSS Definition module is used by system integrators to design SCADA mimic diagrams for monitoring and controlling industrial processes. An attacker could craft a malicious project or diagram file that, when opened by a user, executes arbitrary code with user privileges, potentially leading to loss of system control or data.
What this means
What could happen
An attacker could execute arbitrary code on a system running IGSS Definition by tricking a user into opening a malicious file, potentially gaining full control of the SCADA system and the industrial processes it monitors.
Who's at risk
System integrators, SCADA operators, and engineering staff who use Schneider Electric IGSS Definition to design and maintain SCADA systems in energy (power generation, distribution) and manufacturing facilities are affected. Any organization relying on IGSS for process monitoring and control should prioritize this update.
How it could be exploited
An attacker would need to craft a malicious file (likely a project or diagram file) and get a system integrator or SCADA operator to open it in IGSS Definition on their engineering workstation. Once opened, the vulnerability in the Definition module allows code execution with the privileges of the logged-in user.
Prerequisites
- User interaction required: an engineer or operator must open a malicious file in IGSS Definition
- IGSS Definition module running version 18.0.0.26124 or earlier
- File access to the affected workstation or email-based delivery vector
