Moudi has discovered some vulnerabilities in Facil Helpdesk, which can be exploited by malicious people to conduct cross-site scripting attacks and disclose sensitive information.

1) Input passed via the URL to kbase/kbase.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.

2) Input passed to the "lng" parameter in index.php is not properly sanitised before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks.

The vulnerabilities are confirmed in version 2.3 Lite. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised.
