eliteCMS的安装程序安装结束后未作锁定，导致 可以通过访问安装程序地址进行重复安装
另外一个漏洞是安装程序可以直接写入一句话到admin/includes/config.php
我们来看代码：
...
elseif ($_GET['step'] == "4") {
$file = "../admin/includes/config.php";
$write = "
$write .= "/**\n";
$write .= "*\n";
$write .= "*eliteCMS-The LightweightCMS Copyright 2008 elite-graphix.net.\n";
...略...
$write .= "*\n";
$write .= "*/\n";
$write .= "\n";
$write .= "define(\"DB_SERVER\", \"{$_SESSION['DB_SERVER']}\");\n";
$write .= "define(\"DB_NAME\", \"{$_SESSION['DB_NAME']}\");\n";
$write .= "define(\"DB_USER\", \"{$_SESSION['DB_USER']}\");\n";
$write .= "define(\"DB_PASS\", \"{$_SESSION['DB_PASS']}\");\n";
$write .= "\$connection = mysql_connect(DB_SERVER, DB_USER, DB_PASS);\n";
$write .= "if (!\$connection) {\n";
$write .= " die(\"Database connection failed\" .mysql_error());\n";
$write .= " \n";
$write .= "} \n";
$write .= "\$db_select = mysql_select_db(DB_NAME, \$connection);\n";
$write .= "if (!\$db_select) {\n";
$write .= " die(\"Database select failed\" .mysql_error());\n";
$write .= " \n";
$write .= "} \n";
$write .= "?>\n";
$writer = fopen($file, 'w');
...
在看代码：
$_SESSION['DB_SERVER'] = $_POST['DB_SERVER'];
$_SESSION['DB_NAME'] = $_POST['DB_NAME'];
$_SESSION['DB_USER'] = $_POST['DB_USER'];
$_SESSION['DB_PASS'] = $_POST['DB_PASS'];
取值未作任何验证
如果将数据库名POST数据：
"?>
将导致一句话后门写入/admin/includes/config.php
