Name of the Vulnerable Software and Affected Versions Chadha PHPKB Standard Multi-Language version 9

Description The issue allows attackers to delete any folder on the web server, potentially causing a Denial of Service. This is achieved by using a dot-dot-slash sequence (../) via the crdir parameter in the admin/imagepaster/operations.php file when the action parameter is set to 'df'.

Recommendations For Chadha PHPKB Standard Multi-Language version 9, consider restricting access to the admin/imagepaster/operations.php file to minimize the risk of exploitation.
