Overview

CosmicSting is a Python script designed to exploit an XML External Entity (XXE) vulnerability (CVE-2024-34102) that could potentially lead to arbitrary code execution. This script demonstrates how an attacker could exploit such vulnerabilities to read sensitive files from a server using XML-based requests.

Features

• Exploits an XXE vulnerability to execute malicious requests.
• Generates a callback URL for hosting a DTD file.
• Uses multi-threading for faster exploitation.
• Clears and removes instance logs on the SSRF API after exploitation.

Requirements

• Python 3.x
• Dependencies:
  • requests
  • click
  • fake_useragent

Installation

Clone the repository:

git clone https://github.com/bughuntar/CVE-2024-34102-Python
cd CVE-2024-34102-Python
                Copy
            

Install dependencies using pip:

pip install -r requirements.txt
chmod +x *
                Copy
            

Usage

Run the script with the required URL parameter and optional file parameter:

python cosmic_sting.py --url <target_url> [--file <file_to_read>] [-t <threads>]
                Copy
            

Options:

• -u, --url: Specifies the URL or domain for vulnerability detection. This option is required.
• -f, --file: Allows specifying the file to read from the server. Defaults to /etc/passwd if not provided explicitly.
• -t, --threads: Specifies the number of concurrent threads to use for exploitation. Defaults to 5.

Example:

python cosmic_sting.py --url https://example.com --file /etc/hosts -t 10
                Copy
