User InteractionNone needed
Summary
Spectrum Power 7 before version V24Q3 contains root-owned SUID binaries that allow authenticated local attackers to escalate privileges and gain full control of the system.
What this means
What could happen
An authorized user on a Spectrum Power system could gain root access and modify power grid monitoring or control settings, potentially affecting grid visibility or protection schemes. This could impact reliability of transmitted or distributed power to customers served by that utility.
Who's at risk
Electric utilities and independent system operators (ISOs/TSOs) operating Spectrum Power 7 for grid monitoring, control, or protection. Particularly relevant to any utility using Spectrum Power 7 for SCADA/EMS functions where grid stability or customer reliability depends on the integrity of monitoring and control systems.
How it could be exploited
An attacker with valid login credentials to Spectrum Power 7 (e.g., an insider or compromised user account) can execute a local privilege escalation exploit using root-owned SUID binaries on the system, gaining root/administrative access to the application server.
Prerequisites
- Valid local user account on the Spectrum Power 7 system
- Local access to the affected system (physical or remote session with valid credentials)
- Knowledge of the SUID binary exploit
