IoT 펌웨어 취약점 분석을 위한 프레임워크

Overview

2021-1 캡스톤디자인2(CSE405-00) 수업 프로젝트로 만든 Arduino M0 계열 취약점 분석 툴.

Date

2021.03 ~ 2021.06

Usage

1. Analyze the given firmware:

python3 m0-angr.py --type a --name firm.bin

It generates the followings:

• api.txt: It contains the list of restored APIs.
• cfg.txt: It contains the restored Control-Flow Graph in the form of disassembly.
• vuln.txt: It contains the list of found vulnerabilities.

1. Generate exploitable payloads:

python3 m0-angr.py --type g --name firm.bin --out payload.bin --code {{vuln_offset}} --dest {{dest_offset}} --ret {{ret_offset}}

• {{vuln_offset}}: The offset where vulnerable codes are located(listed in the generated vuln.txt).
• {{dest_offset}}: The offset to jump into. It must be of the prologue in a function.
• {{ret_offset}}: The offset to go back to after its first step of ROP ends.

1. Enjoy~.
