Summary

Spectrum Power 7 before V24Q3 contains multiple root-owned SUID binaries that could allow an authenticated local attacker to escalate privileges and gain full system control.

What this means
What could happen
An attacker with local access to a Spectrum Power 7 system could escalate privileges to root, potentially allowing them to modify grid monitoring data, alter control logic, or disrupt power system operations.
Who's at risk
This affects power grid operators (TSOs and DSOs) and utilities running Siemens Spectrum Power 7 for grid monitoring, analysis, and control. Any organization using this software to manage transmission or distribution systems should prioritize mitigation.
How it could be exploited
An attacker with a local user account on the Spectrum Power 7 system could execute one of the vulnerable SUID binaries to escalate privileges to root. From there, the attacker could modify system configurations, access sensitive grid data, or interfere with power system monitoring and control functions.
Prerequisites
  • Local user account on the Spectrum Power 7 system
  • Access to the device's operating system command line or shell
