CVE-2025-22611

Comprehensive Technical Analysis of CVE-2025-22611

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-22611 CVSS Score: 9.9

The vulnerability in Coolify, an open-source and self-hostable tool for managing servers, applications, and databases, allows any authenticated user to escalate privileges to any role, including the owner role. This privilege escalation can lead to unauthorized access to critical features such as the Terminal, enabling the execution of remote commands. The severity of this vulnerability is rated at 9.9 on the CVSS scale, indicating a critical risk. The high score is justified by the potential for complete system compromise and the ability to execute arbitrary commands remotely.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Authenticated User Privilege Escalation: An attacker with any level of authenticated access can exploit the missing authorization checks to elevate their privileges.
• Remote Command Execution: Once privileges are escalated, the attacker can access the Terminal feature to execute remote commands, potentially leading to full system control.
• Team Member Removal: The attacker can remove other team members, including admins and owners, further consolidating control over the system.

Exploitation Methods:

• Exploiting Missing Authorization: The attacker can send crafted requests to the Coolify API to change their role to a higher privilege level.
• Accessing Terminal Feature: With elevated privileges, the attacker can navigate to the Terminal feature and execute commands.
• Removing Team Members: The attacker can use the elevated privileges to remove other users from the team, ensuring uninterrupted control.

3. Affected Systems and Software Versions

Affected Versions:

• Coolify versions prior to 4.0.0-beta.361

Unaffected Versions:

• Coolify version 4.0.0-beta.361 and later

Affected Systems:

• Any system running Coolify versions prior to 4.0.0-beta.361, including self-hosted instances and cloud-based deployments.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade to the Latest Version: Upgrade Coolify to version 4.0.0-beta.361 or later to mitigate the vulnerability.
• Temporary Access Restrictions: Temporarily restrict access to the Coolify instance to trusted users only until the upgrade is complete.
• Monitor for Suspicious Activity: Implement monitoring to detect any unusual privilege escalation or unauthorized access attempts.

Long-Term Strategies:

• Regular Security Audits: Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.
• Role-Based Access Control (RBAC): Implement strict RBAC policies to limit the actions that users can perform based on their roles.
• Multi-Factor Authentication (MFA): Enforce MFA for all users to add an extra layer of security.
• Logging and Alerting: Enable comprehensive logging and set up alerts for any suspicious activities, especially related to privilege changes and remote command execution.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-22611 highlights the critical importance of proper authorization checks and role management in software applications. This vulnerability underscores the need for:

• Robust Authorization Mechanisms: Ensuring that all actions requiring elevated privileges are properly authorized.
• Continuous Monitoring: Implementing continuous monitoring and incident response mechanisms to detect and mitigate such vulnerabilities promptly.
• Community Collaboration: Encouraging open-source communities to collaborate on identifying and fixing security issues.

6. Technical Details for Security Professionals

Vulnerability Details:

• Missing Authorization Checks: The vulnerability stems from missing authorization checks in the Coolify codebase, allowing any authenticated user to change their role.
• Privilege Escalation: The attacker can send a POST request to the Coolify API endpoint responsible for role management, specifying a higher privilege level.
• Remote Command Execution: With elevated privileges, the attacker can access the Terminal feature and execute arbitrary commands, potentially leading to full system compromise.

Detection and Response:

• Log Analysis: Analyze logs for any unusual privilege changes or unauthorized access attempts.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on suspicious activities related to privilege escalation and remote command execution.
• Incident Response Plan: Develop and implement an incident response plan to quickly address any detected exploitation attempts.

Conclusion: CVE-2025-22611 is a critical vulnerability that underscores the importance of robust authorization mechanisms and continuous security monitoring. Organizations using Coolify should prioritize upgrading to the latest version and implementing the recommended mitigation strategies to protect against potential exploitation.
