PowerChute ICS Flaws: Schneider Electric 2025 Vulnerabilities Expose Critical Manufacturing
Executive Summary
In November 2025, Schneider Electric disclosed multiple vulnerabilities affecting PowerChute Serial Shutdown version 1.3 and earlier, widely deployed in critical manufacturing. The flaws, reported by security researcher Aleksandar Djurdjevic, include a path traversal (CVE-2025-11565), improper authentication attempt controls (CVE-2025-11566), and insecure default permissions (CVE-2025-11567). Successful exploitation could allow attackers on the local network to gain user or system access, potentially compromising operational technology environments. Immediate mitigation involved updating to version 1.4, securing folder permissions, and implementing network isolation practices to reduce exposure.
This incident highlights growing risks to industrial control systems amid increasing convergence of IT/OT and heightened attacker focus on supply chain and infrastructure software weaknesses. Regulatory and business pressures mount as organizations strive to bolster segmentation, logging, and zero trust practices to avoid costly operational disruptions and compliance failures.
Why This Matters Now
With industrial environments increasingly targeted and interconnections between IT and OT networks growing, unpatched vulnerabilities in widely deployed energy management tools like PowerChute present urgent operational and compliance risks, especially for critical manufacturing sectors that depend on uninterrupted power and resilient ICS assets.
Attack Path Analysis
An attacker on the local network exploited weak authentication controls to brute force the REST/shutdownnow endpoint, then leveraged path traversal and improper permissions to gain elevated access on the PowerChute Serial Shutdown system. After gaining user or system-level privileges, the attacker could move laterally within the local network or environment due to insufficient segmentation. The attacker may have established stealthy communications for command and control, and attempted to exfiltrate sensitive configuration or system data. Ultimately, they could disrupt power management by executing shutdowns or corrupt system files, impacting business continuity.
