Varex Imaging 2025: Privilege Escalation Vulnerability in Dental Imaging Software
In December 2025, Varex Imaging disclosed a critical privilege escalation vulnerability (CVE-2024-22774, CVSS v4 8.5) affecting its Panoramic Dental Imaging Software (versions prior to 6.6.1.490). The flaw, caused by an uncontrolled search path element (CWE-427) in the SDK, could enable a standard user to gain NT Authority/SYSTEM privileges through DLL hijacking. While the vulnerability cannot be exploited remotely and no active exploitation has been reported, successful compromise could give attackers unrestricted system access in affected healthcare environments, with the potential to disrupt or manipulate sensitive imaging processes. This incident underscores the persistent risks of local privilege escalation vulnerabilities in healthcare software, especially where operational technology and patient systems converge. With increasing regulatory requirements and a rising focus on vertical-specific threats, incidents like this highlight the urgent need for robust patch management, secure software development practices, and vigilant network segmentation in healthcare environments.
