/*
There are some critical vulnerabilities in this quite pretty CMS..
Vuln N° 1 - Local File Inclusion:
vuln file: includes/head.php
code:
------
if(isset($_COOKIE['theme']) && $_COOKIE['theme'] != "")
{
$default_theme = $_COOKIE['theme'];
}
[...]
include "themes/$default_theme/header.php";
?>
------
attacker can execute a LocalFile by setting the 'theme' cookie value properly;
Es: ../../../../../../etc/passwd%00
Becasuse of the last null char this one works only with MQ=off
Vuln N° 2 - Login Bypass:
vuln file: includes/functions.php
code:
------
// If the member_id cookie is set...
if(isset($_COOKIE['member_id']) && $_COOKIE['member_id'] != 0 && $_COOKIE['member_id'] != "")
{
$id = $_COOKIE['member_id'];
$pass_hash = $_COOKIE['pass_hash'];
$sql = mysql_query("SELECT name FROM $members WHERE id = $id AND member_login_key = '$pass_hash'");
$numrows = mysql_num_rows($sql);
if($numrows != 1)
{
$isLoggedIn = "";
}
else
{
$isLoggedIn = 1;
}
}
------
Attacker can Bypass login by setting 'member_id' cookie value properly and making a SQL Injection attack;
Es: 1--
Vuln N° 3 - connect.php (or what you want) file download:
vuln file: includes/adm/add_dl.php
code:
------
if(isset($_POST['Submit']) && $_POST['title'] != "" && $_POST['file'] != "" && $_POST['desc'] != "")
{
$title = $_POST['title'];
$file = $_POST['file'];
$desc = $_POST['desc'];
$cat = $_POST['cats'];
if(file_exists("Downloads/$file"))
{
mysql_query("INSERT INTO kbx_downloads (cat, name, `desc`, `file`) VALUES('$cat', '$title', '$desc', '$file')");
echo '<div class="container center">Download added!<br />Redirecting...</div>';
echo '<meta http-equiv="refresh" content="1;url=adm_index.php?mod=edit_dl">';
}
else
{
echo '<div class="alert">File Doesnt Exist!</div>';
echo '<meta http-equiv="refresh" content="1;url=adm_index.php?mod=add_dl">';
}
}
------
Attacker with a valid Admin ID can send a malicious file name to download connect.php;
