Unauthenticated file disclosure via unvalidated path
Published Jun 24, 2026 · Updated Jun 24, 2026
Path traversal in ATEN Unizon 2.7.262.002 allows remote attackers to read sensitive files through crafted path input. The writeFileToHttpServletResponse method uses a user-supplied path in file operations without validating that it remains in the intended directory. No authentication or user interaction is required; successful requests disclose files readable in the SYSTEM context without altering data or interrupting service.
