Schneider Electric ProClima Command Injection Vulnerabilities

Act NowICS-CERT ICSA-14-350-01Sep 18, 2014
Summary

Schneider Electric ProClima versions 6.0.1 and earlier contain command injection vulnerabilities (CWE-77) that could allow an attacker to execute arbitrary commands on the affected system.

What this means
What could happen
An attacker with network access to ProClima could execute arbitrary commands on the system, potentially gaining full control of the application and the ability to manipulate energy distribution, monitoring, or control functions.
Who's at risk
Energy utilities and facilities using Schneider Electric ProClima for environmental monitoring and control (HVAC, climate management) should prioritize this issue. Affected systems include ProClima platforms deployed on versions 6.0.1 and earlier at power generation sites, substations, data centers, and other critical infrastructure requiring climate control.
How it could be exploited
An attacker with network access to ProClima could craft malicious input that leverages command injection weaknesses to bypass application validation and execute arbitrary operating system commands with the privileges of the ProClima process.
Prerequisites
  • Network access to ProClima application interface
  • ProClima version 6.0.1 or earlier deployed

0/2
HARDENINGIsolate ProClima systems from untrusted networks using network segmentation and firewall rules—restrict access to only authorized engineering workstations and control systems
WORKAROUNDImplement input validation and monitoring on ProClima network interfaces to detect and block malicious command patterns
