This repository provides a proof-of-concept (PoC) exploit for CVE-2024-22891, a remote code execution vulnerability in nteract 0.28.0. The vulnerability arises from the application's handling of Markdown links, which are rendered in an Electron webview with nodeIntegration enabled. An attacker can craft a malicious HTML page (provided as jruru.html) that, when loaded via a Markdown link in nteract, executes arbitrary code on the victim's system using Electron's shell.openExternal API. The PoC demonstrates launching calc.exe, but any executable could be run. The README.md explains the vulnerability, exploitation steps, and provides example payloads and usage instructions. The main exploit file is jruru.html, which contains the JavaScript payload. The attack vector is network-based, requiring the victim to click or open a malicious link, typically hosted on the attacker's server. The repository is structured with a detailed README and a single HTML payload file.
