LokiCMS是一款简单易用的网络内容管理系统。
LokiCMS的admin.php文件中存在逻辑错误，如果远程攻击者在所提交的HTTP POST请求中设置了LokiACTION和其他参数的话，则无需管理权限就可以设置CMS main settings。
以下是有漏洞的代码段：
# admin.php Lines:24-42
if ( isset ( $_POST ) && isset ( $_POST['LokiACTION'] ) && strlen ( trim ( $_POST['LokiACTION'] )
) > 0 ) {
// we have an action to do
switch ( trim ( $_POST['LokiACTION'] ) ) {
case 'A_LOGOUT': // Logout
unset($_SESSION[PATH]);
break;
case 'A_LOGIN': // Login
if ( isset ( $_POST['login'] ) && sha1 ( $_POST['login'] ) == $c_password )
$_SESSION[PATH] = 'logged in lokicms030';
break;
case 'A_SAVE_G_SETTINGS': //save main settings
writeconfig ( $c_password, $_POST['title'], $_POST['header'], $_POST['tagline'],
$_POST['footnote'], $c_default, $_POST['theme'], $_POST['language'], $_POST['modrewrite'],
$_POST['simplelink'], $_POST['code'] );
$c_theme = $_POST['theme'];
include PATH . '/includes/Config.php';
include PATH . '/languages/' . $c_lang . '.lang.php';
$msg = $lang ['admin'] ['expressionSettingsSaved'];
break;
# includes/Functions.php Lines:163-200
function writeconfig ( $c_password, $c_title, $c_header, $c_tagline, $c_footnote, $c_default,
$c_theme, $c_lang, $c_modrewrite, $c_simplelink, $c_code )
{
.
.
.
$config = '<?php ' . LINEBREAK;
$config .= '// LokiCMS Config file, You can change settings in this file or via admin.php ' .
LINEBREAK;
$config .= '$c_password = \'' . $c_password . '\'; ' . LINEBREAK;
