This repository documents and demonstrates a command injection vulnerability (CVE-2022-45025) in the Mume library, which is used by the Markdown Preview Enhanced extensions for VSCode and Atom. The vulnerability arises from the use of Node.js's spawn function with the {shell: true} option, allowing shell command injection via specially crafted @import statements in Markdown files. The repository contains a detailed README.md explaining the vulnerability, a proof-of-concept (PoC) payload, and a sample malicious Markdown file (examples/malicious.md) that triggers the exploit by opening the Calculator app on macOS. The exploit is triggered when a victim opens a malicious Markdown file with the vulnerable extension, resulting in arbitrary command execution. The repository does not contain exploit code in a programming language, but provides clear PoC payloads and usage instructions. The main attack vector is local, requiring user interaction (opening a malicious file). The repository also references an external endpoint for loading the malicious payload via a remote Markdown file.
