CVE-2026-3669 identifies an improper authorization vulnerability in the AlarmService function of the com.dgen.alarm component within Freedom Factory's dGEN1 product, affecting versions up to 20260221. This flaw allows an attacker with local access and limited privileges to bypass authorization checks, potentially enabling unauthorized manipulation of alarm-related functions. The vulnerability does not require user interaction and has a low complexity for exploitation, but the attack vector is limited to local access, reducing its overall risk profile. The vendor was notified early but has not issued any response or patch, and the vulnerability details have been publicly disclosed, increasing the likelihood of exploitation attempts. The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates local attack vector, low complexity, no user interaction, and partial impacts on confidentiality, integrity, and availability. No known exploits are currently active in the wild. The vulnerability primarily affects organizations deploying Freedom Factory dGEN1 in environments where local user access is possible, such as on-premises installations or systems with multiple users having limited privileges.

The improper authorization vulnerability could allow a local attacker with limited privileges to manipulate alarm functions, potentially leading to unauthorized changes in alarm configurations or suppression of critical alerts. This could degrade the integrity and availability of alarm systems, impacting operational security monitoring and incident response. Confidentiality impact is limited but possible if alarm data or status information is exposed or altered. The requirement for local access limits the scope of impact, but insider threats or compromised local accounts could exploit this vulnerability. Organizations relying on dGEN1 for critical alarm management may face increased risk of undetected security incidents or operational disruptions. The lack of vendor response and patch availability prolongs exposure and complicates remediation efforts.

Until an official patch is released, organizations should implement strict local access controls to limit user privileges on systems running Freedom Factory dGEN1. Employ role-based access control (RBAC) to restrict who can access or modify alarm services. Monitor system logs and alarm service activity for unusual or unauthorized changes. Consider isolating dGEN1 installations to trusted environments with minimal local user access. Use host-based intrusion detection systems (HIDS) to detect suspicious local activity targeting the AlarmService component. Regularly audit user accounts and permissions to prevent privilege escalation. Engage with Freedom Factory for updates and request timely patches. If possible, apply virtual patching or compensating controls such as application-layer firewalls or endpoint protection to mitigate exploitation risk.
