Access of Uninitialized Pointer in AzeoTech DAQFactory 20.7

IdentifiersCVE-2025-66588CWE-824· Access of Uninitialized Pointer

AzeoTech DAQFactory release 20.7 (Build 2555), and according to the provided context release 20.7 and prior, contains an access of uninitialized pointer vulnerability. The issue can be triggered through a malicious .ctl file uploaded to the application and then opened or otherwise processed with user interaction. Accessing an uninitialized pointer can cause memory corruption and unstable program state, which in this case may be leveraged to achieve arbitrary code execution in the context of the current DAQFactory process.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can lead to arbitrary code execution in the context of the affected DAQFactory process. The provided context also indicates memory corruption and potential system instability or crashes as possible outcomes of exploitation. In industrial environments, this could enable compromise of the engineering workstation or host running DAQFactory and create downstream operational risk.

Mitigation

If you can’t patch tonight, do this now.

Until upgrading is completed, restrict access to and ingestion of .ctl files, especially from untrusted sources. Use DAQFactory safe mode where applicable, apply document editing passwords if supported, and limit which users can upload or open project/control files. CISA-recommended defensive measures from the provided context also apply: minimize network exposure of ICS systems, place control-system networks behind firewalls, and secure remote access through VPNs and other hardened access controls.

Remediation

Patch, then assume compromise.

Upgrade AzeoTech DAQFactory to version 21.1, which the provided context identifies as the vendor release addressing these vulnerabilities. More generally, move from release 20.7 (Build 2555) and prior to the vendor-fixed version and validate that untrusted project/control files are not processed by vulnerable installations.
