AI Analysis
Technical Summary
CVE-2026-12921 is a Use After Free vulnerability in AzeoTech DAQFactory affecting versions 21.1 and earlier. The flaw is triggered by processing specially crafted .ctl files, potentially allowing an attacker with local access and requiring user interaction to execute arbitrary code. The vulnerability is rated with a CVSS 4.0 score of 8.4, indicating high severity. There is currently no official patch or remediation guidance from the vendor, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation can lead to arbitrary code execution on affected systems. However, exploitation requires local access and user interaction, which limits remote exploitation scenarios. The vulnerability poses a critical risk to systems running vulnerable versions of DAQFactory if an attacker can deliver a malicious .ctl file and convince a user to open it.
Mitigation Recommendations
No official patch or remediation guidance is currently available from the vendor. Users should avoid opening untrusted .ctl files and restrict local access to trusted users only. Monitor vendor communications for updates regarding a fix or mitigation recommendations.
