Horizon Alert
Summary of the vulnerability and why it matters
Dokploy, a self-hostable Platform as a Service, contains a critical vulnerability that permits authenticated users to write arbitrary files to a server's filesystem. This flaw can be leveraged to achieve remote code execution and bypass container isolation, potentially leading to complete server compromise. The vulnerability allows for data exfiltration and the installation of persistent backdoors without direct user intervention.
- Vulnerable to file writing during deployment.
- Allows arbitrary file write to remote servers.
- Potential for server compromise and data exfiltration.
Attack Path
How an attacker could exploit the issue
This vulnerability allows authenticated users to write arbitrary files to remote server file systems during application deployment. This can lead to remote code execution through cron jobs, enabling complete server compromise, data exfiltration, and persistent backdoor installation. The attack bypasses container isolation on remote deployments.
- Exposure: Network accessible management console.
- Attacker: Authenticated user.
- Trigger: Application deployment with malicious file write.
Live Threat
Current exploitation, exposure, and threat context
The identified vulnerability in Dokploy could allow authenticated users to gain full control over remote servers during application deployment. This could lead to the compromise of sensitive data and the installation of persistent backdoors. The vulnerability bypasses container isolation, enabling extensive damage.
- Attackers with authenticated user access.
- Remote server deployment feature must be enabled.
- Complete server compromise and data exfiltration.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability allows authenticated users to write arbitrary files to a server's filesystem during application deployment, potentially leading to remote code execution and complete server compromise. The impact includes unauthorized access to systems, data exfiltration, and persistent backdoor installation, bypassing container isolation on remote deployments. This presents a significant risk to organizational data and operational continuity.
- Find Dokploy instances that are externally facing.
- Restrict access to Dokploy instances.
- Apply vendor fix and validate.
- Monitor for related issues.
