A vulnerability, which was classified as critical, has been found in Kajona CMS 4.7 (Content Management System). Affected by this issue is the function __construct
of the file /kajona/image.php of the component Image Handler. The manipulation of the argument image
with the input value /files/images/upload/....//....//....//download.php
leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. 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. Impacted is confidentiality.
