Executive Summary
The Rockwell Automation FactoryTalk Historian Site Edition is affected by multiple vulnerabilities, including an authentication bypass security issue, that could allow an attacker to obtain a valid authentication token, perform a denial of service, or crash the system. The affected versions are FactoryTalk Historian SE 11 and earlier, with a CVSS score of 7.7. This poses a significant risk to critical manufacturing sectors worldwide, with potential financial, operational, and reputational impacts.
Threat Analysis
The vulnerabilities exist in the Rockwell Automation FactoryTalk Historian Site Edition, specifically in versions FactoryTalk Historian SE 11 (CVE-2025-13036) and FactoryTalk Historian SE <=11.00 (CVE-2025-44019 and CVE-2025-36539). The authentication bypass security issue (CVE-2025-13036) can be exploited by continually sending requests to the login endpoint, allowing an attacker to obtain a valid authentication token. This can lead to unauthorized access, data manipulation, or disruption of critical manufacturing processes.
Business Impact Assessment
The exploitation of these vulnerabilities could result in significant financial losses due to downtime, production disruptions, and potential intellectual property theft. The operational impact could include compromised product quality, safety risks, and environmental hazards. Reputational damage could also occur, affecting customer trust and loyalty. The critical manufacturing sectors, which are heavily reliant on these systems, are at a higher risk of experiencing these consequences.
SOC Recommendations — Immediate Actions
- Apply the latest security patches and updates to the affected Rockwell Automation FactoryTalk Historian Site Edition systems.
- Implement mitigations and workarounds recommended by Rockwell Automation for customers who cannot upgrade to corrected versions.
- Monitor system logs for suspicious activity, such as repeated login attempts or unusual network traffic.
- Block unnecessary network traffic to the affected systems and limit access to authorized personnel only.
MITRE ATT&CK Mapping
- Tactic: Initial Access (TA0001): Technique - Valid Accounts (T1078)
- Tactic: Execution (TA0002): Technique - Shared Drive (T1080) is not directly applicable, however, the use of shared resources with improper synchronization is mentioned.
Detection Opportunities
Monitor system logs for signs of suspicious activity, such as repeated login attempts, unusual network traffic, or system crashes. Network signatures may include unusual traffic patterns to and from the affected systems. Behavioral indicators could include changes in system performance, data integrity issues, or unexpected system reboots.
Threat Hunting Recommendations
- Hunt for suspicious login activity, such as multiple failed login attempts or logins from unknown IP addresses.
- Investigate unusual network traffic patterns to and from the affected systems.
- Monitor system performance and data integrity for signs of potential exploitation.
