Summary

AVEVA Edge versions 2020 R2 SP1 and all prior versions contain multiple vulnerabilities (CWE-357, CWE-427, CWE-502, CWE-611) that could allow arbitrary code execution, information disclosure, or denial of service when a user opens a malicious project file. The vulnerabilities are exploitable only with local access and require user interaction to trigger. Successful exploitation could result in unauthorized modification of control system projects, access to sensitive configuration data, or system crashes that disrupt operations.

What this means
What could happen
An attacker with local access to a machine running AVEVA Edge could execute arbitrary code with the privileges of the logged-in user, potentially gaining control over the visualization and control system project files, altering setpoints, or disrupting operations.
Who's at risk
Water utilities and electric utilities that use AVEVA Edge (formerly InduSoft Web Studio) for SCADA visualization and project-based automation are affected. This includes any engineering workstations or HMI servers running AVEVA Edge 2020 R2 SP1 or earlier versions.
How it could be exploited
An attacker must trick a user into opening a malicious AVEVA Edge project file from an untrusted source. Once the file is opened by a user on a local machine, the attacker's code executes with that user's privileges, allowing modification of control logic, access to sensitive configuration data, or denial of service through system crashes.
Prerequisites
  • Local access to a machine with AVEVA Edge installed
  • User interaction required—victim must open a malicious project file
  • No special privileges or credentials required to trigger exploitation

0/5
Do now
0/3
HARDENINGApply Access Control Lists (ACLs) to all folders where AVEVA Edge project files are saved and loaded
HARDENINGEstablish and maintain a trusted chain-of-custody process for AVEVA Edge project files during creation, modification, distribution, and use
HARDENINGTrain engineering and operations staff to verify the source of AVEVA Edge project files before opening or executing them
