CVE-2026-9775Network attack vector

Authenticated arbitrary file deletion via uploadSSL path traversal

Published Jun 24, 2026 · Updated Jun 24, 2026

Path traversal in ATEN Unizon 2.7.262.002 allows remote authenticated users to delete arbitrary files through uploadSSL. The uploadSSL method accepts a user-supplied path without restricting it to an intended directory before using that path in file operations. An authenticated session with high privileges is required; deletion of application or system files can interrupt the service.
