Executive Summary
In June 2026, a critical vulnerability (CVE-2026-12390) was identified in AzeoTech's DAQFactory software, versions 21.1 and prior. This Type Confusion flaw allows attackers to execute arbitrary code by tricking users into opening malicious .ctl files. The vulnerability poses significant risks to systems utilizing DAQFactory, potentially leading to unauthorized access and control.
The disclosure underscores the ongoing challenges in securing industrial control systems, especially as attackers increasingly target such environments. Organizations are urged to apply recommended mitigations promptly to prevent exploitation and maintain operational integrity.
Why This Matters Now
The rise in targeted attacks on industrial control systems highlights the urgency for organizations to address vulnerabilities like CVE-2026-12390 to prevent potential disruptions and unauthorized access.
Attack Path Analysis
An attacker crafts a malicious .ctl file exploiting a type confusion vulnerability in AzeoTech DAQFactory, leading to arbitrary code execution upon user interaction. The attacker then escalates privileges within the compromised system, moves laterally to access other critical systems, establishes command and control channels, exfiltrates sensitive data, and ultimately disrupts operations.
