CVE-2022-28523Public exploitNetwork attack vector

Authenticated arbitrary file deletion via path traversal

Published Apr 26, 2022 · Updated Aug 3, 2024

Path traversal in HongCMS 3.0.0 allows remote authenticated users to delete arbitrary files through the template AJAX endpoint. In admin/controllers/template.php, the delete action accepts the POST file value and processes traversal sequences such as ../../../config/config.php without restricting the resolved pathname. A valid backend session is required; deleting config/config.php enables application reinstallation and can interrupt service or destroy site data.
