Cr@zy_King has discovered a vulnerability in Kasseler CMS, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via parameters to index.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
NOTE: A local file inclusion via the "file" parameter in index.php (when "module" is set to "phpManual") was also reported.
The vulnerability is confirmed in version 1.3.1 Lite. Other versions may also be affected.
Solution: Filter malicious characters and character sequences in a proxy.
