A vulnerability, which was classified as problematic, was found in CmsEasy 7.7.7.9. Affected is the function deleteimg_action in the library lib/admin/file_admin.php. The manipulation of the argument imgname leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
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.
