程序介绍:
LokiCMS是一款简单易用的网络内容管理系统。
漏洞分析:
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;
- $config .= '$c_title = \'' . $c_title . '\'; ' . LINEBREAK;
- $config .= '$c_header = \'' . $c_header . '\'; ' . LINEBREAK;
- $config .= '$c_tagline = \'' . $c_tagline . '\'; ' . LINEBREAK;
- $config .= '$c_footnote = \'' . $c_footnote . '\'; ' . LINEBREAK;
- $config .= '$c_default = \'' . $c_default . '\'; ' . LINEBREAK;
- $config .= '$c_theme = \'' . $c_theme . '\'; ' . LINEBREAK;
- $config .= '$c_lang = \'' . $c_lang . '\'; ' . LINEBREAK;
- $config .= '$c_modrewrite = ' . $c_modrewrite . '; ' . LINEBREAK;
- $config .= '$c_simplelink = ' . $c_simplelink . '; ' . LINEBREAK;
- $config .= '$c_code = ' . $c_code . '; ' . LINEBREAK;
- $config .= '?>';
- $handle = fopen ( 'includes/Config.php', 'w' );
- fwrite ( $handle, $config );
- fclose ( $handle );
- }
