User InteractionNone needed
Summary

Spectrum Power 7 is vulnerable to arbitrary code injection by an authenticated local attacker, which could lead to root access. The vulnerability exists in versions prior to 23Q4. This is not remotely exploitable and requires local system access with valid user credentials. No active exploitation has been reported.

What this means
What could happen
An authenticated local attacker could inject code and gain root access to Spectrum Power 7, potentially allowing them to modify power system data, alter control settings, or disrupt energy management operations.
Who's at risk
Energy sector organizations using Siemens Spectrum Power 7 for power system monitoring and management, particularly utilities and power distribution centers that rely on this platform for control and visibility into electrical operations.
How it could be exploited
An attacker with local system access and valid user credentials could execute arbitrary code with elevated privileges. This requires physical or logical local access to the Spectrum Power 7 system, not remote network access.
Prerequisites
  • Local system access required
  • Valid user account credentials needed
  • No remote exploitation possible
  • Attack vector is local only
