PHP-Nuke does not adequately authenticate users thereby allowing attackers to change user information

Vulnerability Note VU#739211

Original Release Date: 2002-09-24 | Last Revised: 2003-11-05

Overview

PHP-Nuke's saveuser() function does not adequately authenticate users. Attackers may exploit this vulnerability to change user data and gain access to accounts.

Description

PHP-Nuke is a set of PHP scripts designed to simplify web site creation and maintenance. PHP-Nuke's saveuser() function does not adequately authenticate users. As a result, attackers who know specific PHP-Nuke user ID's can exploit saveuser() to change PHP-Nuke user data such as email addresses. After changing a user's email address, attackers may request the user's password via email and gain full access to the PHP-Nuke account.

Impact

Remote attackers may change user data and gain access to PHP-Nuke user accounts.

Solution

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