Summary

Siemens Spectrum Power 5 contains a reflected cross-site scripting (XSS) vulnerability in the web interface (CWE-80). An attacker could craft a malicious link that, when clicked by a logged-in operator, executes arbitrary JavaScript in the browser session. This could allow unauthorized access to grid monitoring data or control functions. The vulnerability affects all versions prior to 5.50_HF02. No security update is currently available; vendors are recommended to implement network controls and operational resilience measures per grid regulations.

What this means
What could happen
An attacker could conduct a reflected cross-site scripting (XSS) attack via the web interface, potentially stealing session credentials or manipulating grid control operations viewed by operators. This could compromise situational awareness or allow unauthorized changes to protection settings in a power distribution system.
Who's at risk
Transmission System Operators (TSOs) and Distribution System Operators (DSOs) using Siemens Spectrum Power 5 for grid monitoring and secondary protection coordination are affected. This impacts anyone managing power distribution networks, substations, or grid control centers that rely on this SCADA visualization and control platform.
How it could be exploited
An attacker crafts a malicious URL containing JavaScript code and sends it to a power grid operator (TSO/DSO staff). When the operator clicks the link and views Spectrum Power 5 through the web interface, the script executes in their browser session, allowing the attacker to steal session tokens or perform actions on their behalf against the SCADA system.
Prerequisites
  • User interaction required: operator must click a malicious link
  • Network access to Spectrum Power 5 web interface (typically port 80/443 on internal network)
  • Operator must be logged into the application at time of click
