In today’s interconnected industrial landscape, cybersecurity is no longer just an IT concern—it’s a critical operational necessity. Rockwell Automation, a leader in industrial automation solutions, recently disclosed critical vulnerabilities in its Allen-Bradley PowerMonitor 1000, a device widely used for energy monitoring and control. These vulnerabilities, if exploited, could allow hackers to disrupt industrial operations, bypass authentication, and even execute remote code, potentially compromising entire networks. This article delves into the nature of these vulnerabilities, their potential impact, and the urgent steps organizations must take to safeguard their systems.
of the Vulnerabilities
Rockwell Automation, in collaboration with the Cybersecurity and Infrastructure Security Agency (CISA), has patched three critical vulnerabilities in its Allen-Bradley PowerMonitor 1000. These vulnerabilities, identified as CVE-2024-12371, CVE-2024-12372, and CVE-2024-12373, pose significant risks to industrial control systems (ICS).
1. CVE-2024-12371: This flaw allows an unauthenticated attacker to create a new “Policyholder” user via the device’s API. The Policyholder is the highest privileged user, capable of editing configurations, creating admin accounts, and performing factory resets.
2. CVE-2024-12372: Exploiting this vulnerability could lead to denial-of-service (DoS) attacks or even remote code execution, giving attackers control over the device.
3. CVE-2024-12373: This flaw also enables DoS attacks, potentially disrupting critical industrial operations.
These vulnerabilities affect PowerMonitor 1000 devices running firmware versions prior to 4.020. Vera Mens, a security researcher at Claroty’s Team82, discovered the vulnerabilities and reported them to Rockwell. Mens highlighted that dozens of these devices are exposed to the internet, making them easy targets for attackers.
The exploitation of these vulnerabilities does not require authentication, meaning attackers can target devices directly if they gain access to an organization’s internal network or through internet-exposed devices. The consequences could be severe, including production halts due to inaccurate energy tracking, authentication bypasses, and full network compromise through remote code execution.
Rockwell Automation has released firmware version 4.020 to address these issues, and Claroty has published detailed advisories for each vulnerability. Organizations are urged to update their devices immediately to mitigate these risks.

What Undercode Say:
The discovery of critical vulnerabilities in Rockwell Automation’s PowerMonitor 1000 underscores a growing concern in the industrial cybersecurity landscape. As industrial control systems (ICS) become increasingly interconnected, the attack surface for malicious actors expands, making robust cybersecurity measures more critical than ever.
The Broader Implications
1. Supply Chain Disruptions: The PowerMonitor 1000 is integral to energy monitoring in manufacturing environments. A successful DoS attack could disrupt energy tracking, leading to production halts and supply chain bottlenecks. In industries where downtime equates to significant financial losses, such disruptions can be catastrophic.
2. Network-Wide Compromise: The ability to execute remote code on these devices is particularly alarming. Attackers could use this access as a foothold to infiltrate broader networks, potentially compromising sensitive data or even gaining control over other ICS components.
3. Lack of Authentication Requirements: The fact that these vulnerabilities can be exploited without authentication highlights a critical oversight in device security. This makes it easier for attackers to target devices, especially those exposed to the internet.
The Role of IoT and OT Security
The PowerMonitor 1000 is part of the growing ecosystem of Internet of Things (IoT) and Operational Technology (OT) devices. While these devices offer significant operational efficiencies, they also introduce new risks. Many OT devices were not designed with cybersecurity in mind, making them vulnerable to modern threats.
Organizations must adopt a proactive approach to securing their IoT and OT environments. This includes:
– Regular Firmware Updates: Ensuring devices are running the latest firmware is a basic yet crucial step in mitigating vulnerabilities.
– Network Segmentation: Isolating OT networks from IT networks can limit the spread of attacks.
– Continuous Monitoring: Implementing real-time monitoring solutions can help detect and respond to threats before they escalate.
The Human Factor
While technical solutions are essential, human factors cannot be ignored. Employees must be trained to recognize potential threats, such as phishing attempts that could provide attackers with network access. Additionally, organizations should establish clear protocols for reporting and responding to security incidents.
A Call to Action
The vulnerabilities in the PowerMonitor 1000 serve as a stark reminder of the importance of cybersecurity in industrial environments. As attackers become more sophisticated, organizations must stay ahead by adopting a comprehensive security strategy that addresses both technical and human vulnerabilities.
In conclusion, the patching of these vulnerabilities is a step in the right direction, but it is only the beginning. Industrial organizations must prioritize cybersecurity to protect their operations, supply chains, and ultimately, their bottom line. The time to act is now—before the next vulnerability is exploited.
