# CVE-2024-3673
CVE-2024-3673 Exploit: Local File Inclusion in Web Directory Free WordPress Plugin ( before 1.7.3 )

# Overview

**CVE-2024-3673** describes a critical vulnerability in the Web Directory Free WordPress plugin (versions prior to 1.7.3). The plugin fails to validate a parameter before using it in an `include()` function, which leads to Local File Inclusion (LFI). This allows unauthenticated attackers to read sensitive files on the server.
## Vulnerable Plugin Versions

- Affected Versions: **<= 1.7.2**
- Fixed Version: **1.7.3**

## Exploit Description

An attacker can exploit this vulnerability by sending a crafted `POST` request to the `admin-ajax.php` endpoint, abusing the `w2dc_controller_request` action to include arbitrary files from the server.

## Exploit Script

The provided Python script automates the exploitation process, including:
1. Checking the plugin version by parsing the `readme.txt` file.
2. Verifying if the target is vulnerable.
3. Exploiting the vulnerability to read sensitive files such as `/etc/passwd`.

### Usage

#### Prerequisites
- Python 3.x
- `requests` library

#### Running the Script

```bash
python3 CVE-2024-3673.py --url <TARGET_URL> [--file <TARGET_FILE>]
```

**Example:**

```bash
python3 CVE-2024-3673.py --url http://192.168.100.74/wordpress --file ../../../../../etc/passwd
```

#### Script Options
- `--url`, `-u`: The target WordPress site URL (required).
- `--file`, `-f`: The file to be read on the target server (default: `/etc/passwd`).

### Script Output
- If the plugin version is vulnerable, the script will attempt to exploit the LFI and display the file's content.
- If the plugin version is safe, it will display a message indicating that the site is not vulnerable.

## Mitigation

- **Update Plugin**: Upgrade the Web Directory Free plugin to version **1.7.3** or higher.
- **Server Hardening**:
  - Restrict file permissions to prevent unauthorized access.
  - Use a Web Application Firewall (WAF) to block malicious requests.
- **Monitoring**: Regularly scan your WordPress installation for vulnerabilities.

This script is intended for educational purposes only. Unauthorized use of this exploit on systems you do not own or have explicit permission to test is illegal.
