As cyber threats continue to escalate across digital infrastructure, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued two alarming advisories, putting industrial and healthcare systems on high alert. These warnings reveal newly discovered, high-impact vulnerabilities in two widely-used technologies: KUNBUS GmbH’s Revolution Pi industrial PC and MicroDicom’s DICOM Viewer.
Both tools are critical components within key sectors including manufacturing, energy, transportation, and medical imaging. With the increasing convergence of operational technology (OT) and IT, vulnerabilities like these could offer malicious actors dangerous entry points, leading to system manipulation, data breaches, and even life-threatening disruptions.
The CISA advisories stress immediate mitigation steps, emphasizing updates, authentication enforcement, and stronger network isolation. Failure to act swiftly could leave organizations vulnerable to attacks that go far beyond traditional data theft—potentially compromising patient safety, factory automation, and national infrastructure resilience.
Summary of the Critical Security Advisory
CISA’s dual alert focuses on urgent vulnerabilities in:
1. KUNBUS GmbH Revolution Pi: Open-Source Industrial PC
Platform: Based on Raspberry Pi, used for automation in industrial environments.
Vulnerabilities Identified:
CVE-2025-24522: Missing authentication on Node-RED server, critical severity (CVSS 10.0). Enables full remote control of the system.
CVE-2025-24523: Authentication bypass in PiCtory versions 2.5.0–2.11.1 via path traversal (CVSS 9.8).
CVE-2025-24524: SSI injection flaw in PiCtory allowing malicious code execution (CVSS 9.8).
These flaws could be exploited to shut down operations, alter automated workflows, or inject malicious content—without needing login credentials.
2. MicroDicom DICOM Viewer: Healthcare Imaging Software
Vulnerability (CVE-2025-1002): Insecure certificate validation (CVSS 5.7).
Impact: Allows man-in-the-middle (MITM) attacks and malicious software updates within a hospital or medical network.
Mitigation Steps Advised by CISA
Immediate software updates to patched versions.
Enabling proper authentication mechanisms.
Removing direct internet access to ICS systems.
Segmenting networks and using secure remote access tools.
Conducting impact analysis and employee training on social engineering.
Affected Sectors
Industrial automation (manufacturing, logistics)
Critical infrastructure (energy, water, transport)
Healthcare systems (medical imaging and diagnostics)
CISA strongly urges all organizations using affected platforms to secure their systems now—before attackers exploit these entry points.
What Undercode Say:
The cyber vulnerabilities outlined in the latest CISA bulletins are more than just theoretical flaws—they reflect the growing, tangible risks tied to the convergence of legacy industrial technologies with modern, internet-connected platforms. The Revolution Pi, celebrated for its affordability and flexibility, has ironically become a double-edged sword. Its open-source foundation may encourage innovation, but it also leaves gaping holes for attackers when proper security controls are absent.
Node-RED, a staple in IoT and automation environments, is dangerously exposed without default authentication. This oversight is egregious, especially considering its deep integration into real-time control systems. With a CVSS score of 10.0, this isn’t just a bug—it’s a full-access key to a plant’s automation layer. A skilled attacker could halt machinery, alter process controls, or insert malicious commands, all without raising immediate alarms.
Similarly,
On the healthcare front, MicroDicom’s DICOM Viewer, while not scoring as highly on the CVSS scale, introduces a different but equally insidious risk. Improper certificate validation opens the door to MITM attacks—perfect for adversaries aiming to silently intercept or tamper with sensitive imaging data. In environments where accurate diagnostics are life-critical, this is not just a technical lapse—it’s a public health concern.
These advisories also underscore a deeper, systemic issue: the lack of cybersecurity maturity in industrial and healthcare software development. Many tools prioritize functionality over security, leaving critical systems vulnerable once deployed in live environments. Moreover, patch management remains a persistent challenge—particularly in ICS setups where downtime is costly and complicated.
The rise of Industry 4.0 has brought with it an expanding threat surface. As more operational technology connects to enterprise IT—and by extension, the internet—the need for airtight security practices becomes urgent. Air-gapped systems are increasingly rare. A single vulnerability, especially one as severe as those in Revolution Pi, could cascade into national-scale disruptions.
Organizations must adopt a zero-trust posture, assume breach scenarios, and design their infrastructure around resilience. Patch cycles must be shortened, anomaly detection improved, and access tightly controlled. It’s also crucial that developers treat certificate validation and authentication as non-negotiables, not afterthoughts.
This alert from CISA should serve as a wake-up call for every IT and OT administrator, cybersecurity professional, and vendor in the ecosystem. Complacency is no longer affordable—especially when human lives, power grids, and manufacturing lines are at stake.
Fact Checker Results
Verified: CISA officially released the advisories ICSA-25-121-01 and ICSMA-25-121-01.
Confirmed: CVE details, severity scores, and affected versions match public vulnerability databases.
Accurate: Suggested mitigations are standard cybersecurity best practices for ICS and healthcare IT.
Prediction
As ICS devices and healthcare tools become more interconnected, we will likely see a surge in targeted exploits capitalizing on low-complexity, high-impact vulnerabilities like those in Revolution Pi. Expect attackers to prioritize these vectors due to their widespread deployment and often lax security measures. In the next 12–18 months, regulatory pressure may force vendors to enforce stricter security baselines, including mandatory authentication, encrypted communications, and real-time threat monitoring across all critical infrastructure components.
