Executive Summary

A recently disclosed vulnerability in AzeoTech DAQFactory, a software used in critical manufacturing sectors worldwide, poses a significant risk to enterprise security. The vulnerability, identified as CVE-2026-12390, has a CVSS score of 7.8 and can be exploited to achieve arbitrary code execution. This vulnerability affects all versions of AzeoTech DAQFactory up to and including version 21.1.

Threat Analysis

The vulnerability in AzeoTech DAQFactory is a Type Confusion vulnerability, which can be exploited by an attacker using specially crafted .ctl files. This can result in code execution, allowing the attacker to gain control over the affected system. The attack vector for this vulnerability is through the upload of malicious .ctl files, which can be done by an attacker with access to the system. The affected systems are those running AzeoTech DAQFactory versions 21.1 and prior.

Business Impact Assessment

The exploitation of this vulnerability could have significant financial, operational, and reputational impacts on enterprises. The arbitrary code execution capability could allow attackers to disrupt or disable critical manufacturing processes, resulting in lost productivity and revenue. Additionally, the potential for data theft or manipulation could lead to reputational damage and regulatory penalties. The CVSS score of 7.8 indicates a high severity vulnerability, and the fact that it can be exploited with low complexity and low privileges increases the likelihood of a successful attack.

SOC Recommendations — Immediate Actions

• Apply the latest patch to AzeoTech DAQFactory to update to a version greater than 21.1.
• Store .ctl files in a folder only writeable by admin-level users to prevent unauthorized access.
• Operate in "Safe Mode" when loading documents that have been out of control to prevent potential exploitation.
• Apply a document editing password to documents to add an additional layer of security.

MITRE ATT&CK Mapping

• Tactic: Execution (T1204): The attacker can execute arbitrary code on the affected system.
• Tactic: Defense Evasion (T1497): The attacker can use the Type Confusion vulnerability to evade security controls.

Detection Opportunities

Enterprises can monitor log sources for suspicious activity related to the upload of .ctl files, such as unusual file access or modification. Network signatures can be used to detect potential exploitation attempts, and behavioral indicators such as unusual system or process activity can be used to identify potential attacks.

Threat Hunting Recommendations

• Hunt for suspicious .ctl file uploads or modifications, particularly those that occur outside of normal business hours or from unfamiliar sources.
• Investigate unusual system or process activity that may indicate exploitation of the vulnerability.
• Search for potential indicators of compromise, such as unexpected changes to system configurations or unusual network activity.

CYBERDUDEBIVASH® Analyst Commentary

This vulnerability highlights the importance of keeping software up to date and patching known vulnerabilities in a timely manner. The fact that this vulnerability can be exploited with low complexity and low privileges increases the likelihood of a successful attack, making it a high priority for remediation. Enterprises should take immediate action to apply the latest patch and implement additional security controls to prevent potential exploitation.

Enterprise Recommendations

• Conduct a thorough inventory of all systems running AzeoTech DAQFactory and prioritize patching of vulnerable systems.
• Implement additional security controls, such as access controls and monitoring, to prevent potential exploitation.
• Develop and implement a comprehensive incident response plan to quickly respond to potential attacks.
• Provide training to users on the importance of security and the potential risks associated with uploading documents from unknown sources.

Key Takeaways

• AzeoTech DAQFactory versions 21.1 and prior are vulnerable to a Type Confusion vulnerability that can be exploited for arbitrary code execution.
• The vulnerability has a CVSS score of 7.8 and can be exploited with low complexity and low privileges.
• Enterprises should take immediate action to apply the latest patch and implement additional security controls.
• Monitoring log sources and network activity can help detect potential exploitation attempts.
• Implementing a comprehensive incident response plan can help quickly respond to potential attacks.
