MyBB private.php Cross-Site Request Forgery and Cross-Site Scripting Advisory Available in Danish  Advisory Available in German 

Secunia Advisory: SA23934  
Release Date: 2007-01-25
Last Update: 2007-03-29

Critical:
Less critical
Impact: Cross Site Scripting
Where: From remote
Solution Status: Partial Fix

Software:MyBB (formerly MyBulletinBoard) 1.x

CVE reference:CVE-2007-0544 (Secunia mirror)
CVE-2007-0622 (Secunia mirror)



Description:
Some vulnerabilities have been discovered in MyBB, which can be exploited by malicious people to conduct cross-site request forgery attacks and cross-site scripting attacks.

1) The application allows users to send messages via HTTP requests without performing any validity checks to verify the request. This can be exploited to send messages to arbitrary users by e.g. tricking a target user into visiting a malicious website.

2) Input passed to the form field "Subject" in private.php is not properly sanitised before it is returned to the user when previewing private messages. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Successful exploitation of the vulnerabilities requires that the target user is logged in.

The vulnerabilities are confirmed in version 1.2.2. Other versions may also be affected.

Solution:
Update to version 1.2.3, which fixes vulnerability #2.

Do not visit untrusted sites while being logged in to MyBB.
