CVE-2025-7330 is a Cross-Site Request Forgery (CSRF) vulnerability identified in Rockwell Automation's Comms - 1783-NATR product, specifically affecting versions 1.006 and earlier. The vulnerability results from the absence of CSRF token validation on a web-based configuration form, which is used to manage critical communication settings in industrial environments. An attacker can exploit this flaw by crafting a malicious link that, when visited by an authenticated administrator, triggers unauthorized configuration changes without their consent. The attack vector is network-based and does not require any privileges or authentication, but it does require user interaction in the form of clicking or visiting the malicious link. The vulnerability impacts the integrity and availability of the system by potentially altering configurations that could disrupt communication or control processes. The CVSS 4.0 score of 7.0 reflects a high severity due to the ease of exploitation and the critical nature of the affected system. No public exploits have been reported yet, but the risk remains significant given the product's deployment in industrial control systems. The lack of CSRF protections indicates a design oversight in the web interface security, which is critical for devices managing industrial communications. The vulnerability was reserved in July 2025 and published in October 2025, with no patches currently available, emphasizing the need for interim mitigations. Rockwell Automation's Comms - 1783-NATR is widely used in manufacturing and critical infrastructure sectors, making this vulnerability a notable threat to operational technology (OT) environments.

The primary impact of CVE-2025-7330 is on the integrity and availability of industrial communication configurations managed by the affected Rockwell Automation product. Unauthorized configuration changes could lead to communication failures, misrouting of control signals, or disruption of industrial processes, potentially causing operational downtime or safety hazards. For European organizations, especially those in manufacturing, energy, transportation, and critical infrastructure sectors, this could translate into significant operational and financial losses. The vulnerability's exploitation requires user interaction but no authentication, increasing the risk of successful attacks through social engineering or phishing campaigns targeting administrators. Given the strategic importance of industrial control systems in Europe, any disruption could have cascading effects on supply chains and public services. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability details become widely known. The high CVSS score underscores the potential severity, and the lack of patches necessitates proactive defense measures. Additionally, regulatory compliance frameworks in Europe, such as NIS2 and GDPR, may impose reporting and remediation obligations if exploitation leads to data breaches or service disruptions.

1. Monitor Rockwell Automation's official channels closely for the release of security patches addressing CVE-2025-7330 and apply them immediately upon availability. 2. Implement strict network segmentation to isolate the affected Comms - 1783-NATR devices from general IT networks and limit access to trusted administrative hosts only. 3. Enforce multi-factor authentication (MFA) for all administrative access to the device's web interface to reduce the risk of compromised credentials being exploited. 4. Educate administrators and operators about the risks of phishing and social engineering attacks that could lead to inadvertent clicking of malicious links. 5. Deploy web security gateways or email filtering solutions that can detect and block malicious URLs or payloads targeting administrative users. 6. Conduct regular audits of device configurations and logs to detect unauthorized changes promptly. 7. Where possible, disable or restrict web interface access to the Comms - 1783-NATR device unless absolutely necessary, using VPNs or jump hosts for remote management. 8. Consider implementing Content Security Policy (CSP) and SameSite cookie attributes if the device supports custom configuration to mitigate CSRF risks. 9. Collaborate with industrial cybersecurity specialists to perform penetration testing and vulnerability assessments focused on OT environments. 10. Prepare incident response plans specific to ICS environments to quickly respond to any suspected exploitation.
