HongCMS 3.0.0 allows arbitrary file deletion via a ../ in the file parameter to admin/index.php/database/ajax?action=delete, a similar issue to CVE-2018-16774. (If the attacker deletes config.php and visits install/index.php, they can reinstall the product.)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
