CVE-2026-9778
ATEN Unizon ImportDeviceList Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of ATEN Unizon. Authentication is required to exploit this vulnerability.
The specific flaw exists within the ImportDeviceList method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-28579.
