CVE-2024-21534 is a remote code execution vulnerability in jsonpath-plus caused by insufficient sanitization of attacker-controlled JSONPath input and unsafe default evaluation through Node.js vm. Crafted expressions can bypass attempted sanitization controls and cause arbitrary JavaScript to be evaluated in the context of the host process. Earlier remediation attempts in jsonpath-plus 10.0.0 through 10.1.0 remained bypassable through alternative payloads.

This repository provides a proof-of-concept (POC) exploit for CVE-2024-21534, a critical remote code execution vulnerability in the jsonpath-plus package (versions prior to 10.2.0) for Node.js. The repository contains three files: a LICENSE, a README.md with detailed usage instructions and background, and the main exploit script 'cve-2024-21534.sh'. The bash script is the core exploit, requiring three arguments: the victim's vulnerable endpoint URL, the attacker's IP, and the attacker's port. The script checks for a running netcat listener on the attacker's machine, then crafts and sends a malicious JSON payload via HTTP POST to the target. This payload exploits unsafe input handling in jsonpath-plus, causing the server to execute a reverse shell command that connects back to the attacker. The exploit is operational and provides a working reverse shell if the target is vulnerable and properly configured. No hardcoded endpoints are present; the script is parameterized for flexible targeting. The attack vector is network-based, requiring access to a vulnerable web endpoint.
