Summary

Schneider Electric IGSS Data Server contains multiple vulnerabilities in its TCP interface that allow unauthenticated remote access. These flaws (CWE-306 missing authentication, CWE-120 buffer overflow) could enable remote code execution, unauthorized data modification or deletion in the Report folder, and denial of service. The Data Server is a core component used by other IGSS modules to access and manage SCADA system data. Successful exploitation in production mode could result in loss of process control and disclosure of sensitive operational data.

What this means
What could happen
An attacker could gain remote control over your SCADA Data Server without authentication, allowing them to alter process data, stop operations, or delete historical records stored in the Report folder. This could result in loss of visibility and control over your industrial processes.
Who's at risk
Energy utilities and manufacturing facilities using Schneider Electric IGSS for process monitoring and control. Specifically, any organization relying on IGSS Data Server for SCADA operations, process data access, and reporting should prioritize this update. Critical impact on water treatment, power distribution, and industrial automation where loss of control or data integrity is unacceptable.
How it could be exploited
An attacker with network access to the Data Server TCP interface (default or custom port) can send crafted requests that bypass authentication checks and trigger buffer overflow or input validation flaws. This allows direct code execution on the SCADA server or manipulation of data files without logging in.
Prerequisites
  • Network access to IGSS Data Server TCP port
  • No authentication credentials required
  • IGSS Data Server version 15.0.0.22170 or earlier running
