Assigner: GitHub, Inc.

Description
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to version 4.0.0-beta.451, an authenticated command injection vulnerability in the Dynamic Proxy Configuration Filename handling allows users with application/service management permissions to execute arbitrary commands as root on managed servers. Proxy configuration filenames are passed to shell commands without proper escaping, enabling full remote code execution. Version 4.0.0-beta.451 fixes the issue.

Executive Summary

This vulnerability is an authenticated command injection in Coolify versions prior to 4.0.0-beta.451. It occurs in the handling of Dynamic Proxy Configuration Filenames, where filenames are passed to shell commands without proper escaping. This allows users with application or service management permissions to execute arbitrary commands as the root user on managed servers, leading to full remote code execution.

Impact Analysis

The vulnerability can have severe impacts, including unauthorized execution of arbitrary commands with root privileges on managed servers. This can lead to complete compromise of the affected servers, data breaches, service disruption, and potential further exploitation within the network.

Mitigation Strategies

Upgrade Coolify to version 4.0.0-beta.451 or later, as this version fixes the authenticated command injection vulnerability in the Dynamic Proxy Configuration Filename handling. Additionally, restrict application/service management permissions to trusted users only to minimize risk until the upgrade is applied.
