Description:
Janek Vind has reported some vulnerabilities in PHP-Nuke, allowing malicious people to conduct SQL injection and Cross Site Scripting attacks.
1) Input passed to the "user" parameter is base64 decoded before it is used in SQL queries. This allows malicious people to include characters, which normally would be filtered and thereby manipulate SQL queries. Examples have been posted, which can be exploited to bypass the authentication procedure and read private messages.
This can also be exploited to conduct Cross Site Scripting attacks if certain themes are used.
2) A vulnerability similar to #1 affects the "admin" parameter. An example has been posted, which can be exploited to perform certain administrative functions such as adding users.
The vulnerabilities have been reported in versions 6 through 7.2.
Solution:
Edit the source code to ensure that input is properly verified.
Use another product.
