CVE-2024-41110 Docker Security Checker

This tool is designed to check multiple hosts for vulnerabilities related to CVE-2024-41110 in Docker installations. It specifically looks for vulnerable Docker versions and the use of AuthZ plugins, which can potentially lead to security issues.

Features

• Checks multiple hosts in parallel for efficient scanning
• Detects vulnerable Docker versions
• Identifies usage of AuthZ plugins
• Generates a comprehensive summary report
• Provides a remediation plan for affected hosts
• Supports both password-based and key-based SSH authentication

Requirements

• Python 3.6 or higher
• Fabric library (pip install fabric)

Installation

1. Clone this repository:

   git clone https://github.com/vvpoglazov/cve-2024-41110-checker.git
   cd cve-2024-41110-checker
   

2. Install the required Python library:

   pip install fabric
   

Usage

Run the script with the following command:

python cve_2024_41110_checker.py <username> <hosts_file> <output_directory> [-k <key_file>]

• <username>: SSH username for connecting to the hosts
• <hosts_file>: Path to a file containing a list of hostnames or IP addresses (one per line)
• <output_directory>: Directory where the script will store individual host reports and the summary report
• -k <key_file>: (Optional) Path to SSH private key file for authentication

Examples:

Using password-based authentication:

python cve_2024_41110_checker.py admin hosts.txt ./reports

Using key-based authentication:

python cve_2024_41110_checker.py admin hosts.txt ./reports -k /path/to/private_key

If you don't provide the -k option, the script will prompt you for the SSH password. Using key-based authentication is recommended for better security, especially in production environments.

Output

The script generates two types of output:

1. Individual host reports: Detailed information about each host's Docker installation and vulnerability status.
2. Summary report: An overview of all scanned hosts, including:
   • Total number of hosts checked
   • Number of vulnerable hosts
   • Number of hosts without Docker running
   • Number of hosts with errors during the check
   • List of vulnerable hosts with their Docker versions
   • Remediation plan

The summary report is both saved to a file and displayed in the console after the script finishes execution.

Affected Docker Versions

This tool checks for the following vulnerable Docker versions:

• v19.03.15 and earlier
• v20.10.27 and earlier
• v23.0.14 and earlier
• v24.0.9 and earlier
• v25.0.5 and earlier
• v26.0.2 and earlier
• v26.1.4 and earlier
• v27.0.3 and earlier
• v27.1.0

Remediation

If vulnerable hosts are detected, consider the following remediation steps:

1. Update to the most recent patched version of Docker.
2. If immediate update is not possible:
   • Avoid using AuthZ plugins
   • Restrict access to the Docker API to trusted parties, following the principle of least privilege
