Published Jun 24, 2026 · Updated Jun 24, 2026
Path traversal in updateLicense in ATEN Unizon 2.7.262.002 allows remote authenticated users to delete arbitrary server files. The method uses a user-supplied path in a file operation without validating that the resolved target remains inside the intended directory. High-privilege authentication is required; deletion of selected files can corrupt application data or cause a service interruption.
