BUGTRAQ  ID: 38116

evalSMSI是用PHP/MySQL开发的WEB应用，用于评估信息安全管理系统。

evalsmsi中存在多个输入验证和明文口令等安全漏洞，远程攻击者可以利用这些漏洞获得非授权访问或执行SQL注入、跨站脚本等攻击。

1 - 不安全口令存储

数据库中以明文存储了口令：

table : authentification
column: password

2 - 绕过认证

用户可通过ajax.php提交某些请求，这样就无需认证便获得了对应用的访问。

3 - SQL注入

可通过向ajax.php脚本提交恶意参数请求执行跨站脚本攻击。以下是有漏洞的代码段：

$id = $_GET['query'];
$action = $_GET['action'];

$base = evalsmsiConnect();
switch ($action) {
case 'sub_par':
$request = "SELECT MAX(numero) FROM sub_paragraphe WHERE id_paragraphe="$id"";
break;
case 'question':
$request = "SELECT * FROM sub_paragraphe WHERE id_paragraphe="$id"";
break;
case 'num_quest':
$request = "SELECT MAX(numero) FROM question WHERE id_sub_paragraphe="$id"";
break;
default:
break;

4 - 跨站脚本

可向报表的标注框中注入JavaScript，执行存储式跨站脚本攻击。
