phpBB < 2.0.19 Multiple XSS

medium Nessus Plugin ID 20379

Synopsis

The remote web server contains a PHP application that is affected by several flaws.

Description

According to its version number, the remote version of this software is vulnerable to JavaScript injection issues using 'url' bbcode tags and, if HTML tags are enabled, HTML more generally. This may allow an attacker to inject hostile JavaScript into the forum system to steal cookie credentials or misrepresent site content. When the form is submitted, the malicious JavaScript will be incorporated into dynamically-generated content.

In addition, an attacker may be able to learn the full path of the install by calling 'admin/admin_disallow.php' provided PHP's 'register_globals' and 'display_errors' are both enabled.

Solution

Upgrade to phpBB version 2.0.19 or later.
