Executive Summary
In June 2026, Rockwell Automation disclosed multiple vulnerabilities in its FactoryTalk Historian Site Edition (SE) software, specifically affecting versions up to 11.00. The most critical, CVE-2025-13036, is an authentication bypass issue where an attacker can obtain a valid authentication token by repeatedly sending requests to the login endpoint. Additionally, CVE-2025-44019 and CVE-2025-36539 involve uncaught exceptions that could allow authenticated users to crash essential subsystems, leading to denial of service and potential data loss. These vulnerabilities pose significant risks to industrial control systems relying on this software. (rockwellautomation.com)
The disclosure underscores the ongoing challenges in securing industrial control systems, highlighting the necessity for continuous monitoring and timely patching. Organizations must remain vigilant, as such vulnerabilities can be exploited to disrupt critical manufacturing operations, emphasizing the importance of robust cybersecurity practices in industrial environments.
Why This Matters Now
The recent disclosure of these vulnerabilities in Rockwell Automation's FactoryTalk Historian SE highlights the critical need for immediate attention to industrial control system security. Exploitation of these flaws could lead to unauthorized access and operational disruptions, posing significant risks to critical manufacturing processes. Organizations must prioritize patching and implementing robust security measures to mitigate these threats.
Attack Path Analysis
An attacker exploited a race condition in the login endpoint of FactoryTalk Historian SE to bypass authentication and gain unauthorized access. With this access, the attacker escalated privileges by exploiting misconfigured permissions, allowing them to execute code with elevated rights. The attacker then moved laterally within the network, accessing other critical systems. They established a command and control channel to maintain persistent access and control over the compromised systems. Sensitive data was exfiltrated through the established channel. Finally, the attacker executed a denial of service attack by exploiting uncaught exceptions, causing system crashes and data loss.
