PHPNuke 'admin.php' script does not adequately authenticate users, thereby allowing malicious user to copy, move, or upload files

Vulnerability Note VU#933955

Original Release Date: 2002-09-24 | Last Revised: 2002-09-24


PHPNuke's "admin.php" script does not properly authenticate users of its filemanager capabilities. Attackers may exploit this vulnerability to copy, move, or upload files.


PHPNuke is a set of PHP scripts designed to simplify website creation and maintenance. The "admin.php" script of PHPNuke includes "filemanager" capabilities allowing an administrative user to copy and move files on the server and to upload new files to the server.

However, this script does not properly verify user authentication. Therefore, any remote attacker can access the filemanager capabilities with PHPNuke administrator privileges.


Remote attackers can copy and move files on the server and upload new files, potentially overwriting existing files.


The CERT/CC is currently unaware of a practical solution to this problem.
