Falt4 CMS Cross-Site Request Forgery and Security BypassSecunia Advisory: SA33973

Release Date: 2009-02-17

Critical:

Highly critical

Impact: Security Bypass

Cross Site Scripting

System access

Where: From remote

Solution Status: Unpatched

Description:

A security issue and a vulnerability have been discovered in Falt4 CMS, which can be exploited by malicious people to bypass certain security restrictions and conduct cross-site request forgery attacks.

1) The security issue is caused due to incorrect security restrictions on the "modules/newsletter/FCKeditor/editor/filemanager/browser/default/connectors/php/connector.php" script. This can be exploited to upload malicious PHP scripts with the e.g. pht extension to the web server.

Successful exploitation of this security issue requires a certain server configuration (e.g. an Apache server with the "mod_mime" module installed).

2) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. change the administrator's password by tricking the user into visiting a malicious web site.
