Introduction
As the digital landscapes intertwine with industrial control systems (ICS), vulnerabilities in popular automation software can pose significant threats to critical infrastructure. The recent advisory from the Cybersecurity and Infrastructure Security Agency (CISA) dated September 19, 2024, highlights a critical security vulnerability in Rockwell Automation's RSLogix 5 and RSLogix 500 software. With a CVSS v4 score of 8.8, this flaw enables potential attackers to execute code remotely, raising alarms for stakeholders in industrial sectors that rely on these tools for automation processes.
Technical Details
CISA outlines a significant vulnerability identified as CVE-2024-7847. The issue arises from insufficient verification of data authenticity within the RSLogix suite, specifically versions of RSLogix 5, RSLogix 500, and RSLogix Micro Developer and Starter. The concern is primarily about the ability of the software to execute embedded VBA scripts automatically when project files are opened, a feature that attackers can exploit to run malicious code without user consent. This raises not just local risks but also potential for exploitation in managed environments given the right conditions, particularly in complex industrial systems.
The implications of exploiting this vulnerability can be severe, allowing unauthorized access to execute commands or alter processes. Given the high complexity of attacks associated with this flaw, this presents significant risk for industries classified under critical manufacturing sectors worldwide. To effectively manage this risk, organizations are advised to pattern mitigation strategies and implement rigorous security measures, ensuring their control systems are fortified against such threats.
Mitigations
CISA and Rockwell Automation have recommended a suite of defensive measures aimed at minimizing exposure to this vulnerability:
Expert Commentary
Industry experts emphasize that the exploitability of this vulnerability is significant enough to warrant immediate attention, especially for those engaged in sectors that leverage RSLogix for automation. The advisory serves as a reminder of the increasing complexity of security in industrial contexts where operational technology intersects with information technology. In the landscape of cybersecurity, the notion that all connected devices are potential targets remains crucial.
Moreover, organizations are encouraged not only to implement the recommended mitigations but also to adopt holistic security measures, incorporating advanced threat detection and response capabilities while fostering a culture of cybersecurity awareness among their workforce.
Historical Context
Security vulnerabilities in automation software have a history of consequences, with previous incidents illustrating the critical need for security in industrial applications. The emergence of sophisticated attack vectors necessitates that enterprises remain vigilant and proactive. The lessons gleaned from past exploitations underscore the importance of rigorous security assessments and the imperative of constant vigilance in monitoring the cybersecurity landscape.
Conclusion
The advisory regarding Rockwell Automation’s RSLogix software is a stark reminder of the vulnerabilities that can exist in vital industrial software. With exploitation possibilities that can lead to severe operational disruptions, stakeholders must take immediate action to safeguard their environments. CISA's recommendations not only point toward mitigating the current threat but also pave the way for a mindset focused on continuous improvement in the realm of cybersecurity within industrial operations.
In the ever-evolving cyber threat landscape, remaining informed and prepared is the best strategy for resilience in critical manufacturing sectors. Organizations are not just encouraged to make these changes; they must prioritize cybersecurity to protect their investments, productivity, and ultimately, the safety of their operations.

Affected Products
- RSLogix 500: All versions
- RSLogix Micro Developer and Starter: All versions
- RSLogix 5: All versions
Vulnerability Overview
- CWE-345: This categorization underlines the problem of insufficient data authenticity checks, which is critical in environments reliant on automation. Attackers leveraging this vulnerability could potentially manipulate project files to execute harmful scripts, leading to disastrous outcomes in automated manufacturing processes.
The implications of exploiting this vulnerability can be severe, allowing unauthorized access to execute commands or alter processes. Given the high complexity of attacks associated with this flaw, this presents significant risk for industries classified under critical manufacturing sectors worldwide. To effectively manage this risk, organizations are advised to pattern mitigation strategies and implement rigorous security measures, ensuring their control systems are fortified against such threats.
Mitigations
CISA and Rockwell Automation have recommended a suite of defensive measures aimed at minimizing exposure to this vulnerability:
- Disable VBA Execution: Users should deny the execution features within the FactoryTalk Administration Console when not needed.
- Use Trusted Locations: Project files should be saved only in locations that are secure and restrict access to administrators.
- Implement VBA Editor Protection: Set password protection on the VBA code to prevent unauthorized access and modifications.
