Introduction:
In a major development for the cybersecurity landscape of industrial systems, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued three urgent advisories targeting critical vulnerabilities in automation tools developed by Schneider Electric and Mitsubishi Electric. These flaws affect core systems responsible for power distribution, home automation, and industrial controlāsystems vital to the backbone of global infrastructure. As hackers increasingly set their sights on operational technology (OT), the latest vulnerabilities raise alarm bells about the growing risks facing energy grids, manufacturing plants, and smart buildings. The flaws underscore the pressing need for industries to harden their security posture as the line between digital and physical threats continues to blur.
Recent ICS Vulnerabilities Shake Industrial Sector
On June 3, 2025, CISA released three crucial Industrial Control Systems (ICS) advisories, sounding the alarm on vulnerabilities that could potentially disrupt core operational systems. These advisories center on security flaws discovered in automation platforms from Schneider Electric and Mitsubishi Electricātwo industry leaders powering infrastructure across energy, manufacturing, and smart buildings.
Two advisories focus on Schneider Electric. The first, ICSA-25-153-01, addresses vulnerabilities in the Wiser Home Automation system. This platform is often used in residential and light commercial buildings to manage lighting, HVAC, and security. Flaws in this system could compromise critical building functions, putting both comfort and safety at risk.
The second Schneider-related advisory, ICSA-25-153-02, covers the EcoStruxure Power Build Rapsody, a platform essential for electrical distribution and infrastructure management in commercial and industrial setups. Any vulnerabilities in Rapsody could enable unauthorized access to power systems, threatening operational continuity and safety.
The third advisory, ICSA-25-153-03, targets Mitsubishi Electricās MELSEC iQ-F Series programmable logic controllers (PLCs). These devices are central to automation in manufacturing and process control. Given their deep integration into physical machinery, any breach could extend beyond cyber into the physical world, affecting production lines, safety systems, and critical infrastructure.
CISAās alerts emphasize the severity of the situation and call on affected organizations to immediately review the technical specifics, apply patches, and enhance defensive measures like network segmentation and access control.
The simultaneous exposure of products from two major vendors suggests either a coordinated research effort or systemic security issues within their development pipelines. Regardless of the root cause, the implications are wide-rangingāunderscoring how essential it is for companies to stay proactive in an age where cyber threats can have real-world consequences.
What Undercode Say:
The simultaneous issuance of advisories for Schneider Electric and Mitsubishi Electric isnāt just a routine bulletināitās a flashing red light for the entire OT security community. Industrial systems are increasingly becoming soft targets for sophisticated adversaries. The fact that these vulnerabilities impact automation platforms embedded in essential infrastructure such as power grids and manufacturing processes raises serious concerns.
Letās break this down. The Wiser Home Automation System might seem benign on the surface, serving homes and small offices. But once breached, it could be used to pivot into larger corporate networks, especially when integrated into smart building environments. Vulnerabilities here could disrupt climate control, disable alarms, or even manipulate lighting to create physical risks.
More pressing is the EcoStruxure Power Build Rapsody platform. Used in large-scale industrial environments, any weakness in this system could grant an attacker the ability to control or shut down electrical distribution. Imagine a malicious actor cutting off power to critical operations during peak hoursāthis isn’t just an IT concern, it’s a business continuity and public safety issue.
Then thereās Mitsubishiās MELSEC iQ-F PLCs, which connect directly to industrial machines. A compromise here isnāt hypotheticalāitās kinetic. Attackers could force machines into failure states, halt production lines, or worse, trigger malfunctions in facilities handling hazardous materials.
Whatās troubling is the recurring nature of these advisories involving top-tier industrial vendors. It hints at either chronic oversights in secure development lifecycles or insufficient third-party testing. As industrial systems become more connected, the traditional air-gapped model of security is no longer viable. Companies need a mindset shift: from reactive patching to proactive threat modeling and secure-by-design engineering.
CISA’s timely advisories are crucial, but their effectiveness hinges on swift action. Simply knowing about vulnerabilities isn’t enoughāmitigations must be deployed, and operators must understand their systems well enough to monitor for exploitation.
These issues also highlight the importance of supply chain security. Vendors providing foundational technology for infrastructure need to embrace continuous vulnerability scanning, code audits, and third-party testing. Relying on post-release patches isn’t a strategy, it’s a liability.
Organizations must also invest in OT-specific cybersecurity solutions, as traditional IT firewalls and endpoint protections often donāt translate effectively in industrial contexts. Visibility, segmentation, and anomaly detection are key pillars that need to be in place nowānot after an incident.
The message is clear: vulnerabilities in industrial automation

š The CISA advisories are officially documented and were released on June 3, 2025.
š§ All three vulnerabilities affect industrial automation platforms from Schneider and Mitsubishi.
ā ļø Each flaw carries operational risks that could impact physical infrastructure and safety.
Prediction š®
Given the frequency and severity of ICS vulnerabilities in recent years, we predict that CISA will continue to issue similar high-priority advisories targeting industrial automation systems. Vendors like Schneider and Mitsubishi will likely be pushed to adopt stricter secure development standards and deeper transparency in their patch management processes. As threat actors become more skilled in targeting OT environments, expect to see a surge in targeted ransomware and state-sponsored campaigns aiming to exploit these very systems. Industrial cybersecurity is no longer optionalāit’s the next frontline.
