Horizon Alert
Summary of the vulnerability and why it matters
This advisory details a critical vulnerability in Dokploy, a self-hosted Platform as a Service. An authenticated user can exploit this flaw to execute arbitrary operating system commands on the server, potentially leading to unauthorized access and modification of host files. The main concern is confirming relevance and exposure, as the platform manages deployments and infrastructure.
- Malicious code execution via server command injection.
- Platform management makes it a potential target.
- Confirm if Dokploy is used and affected.
Attack Path
How an attacker could exploit the issue
An attacker with project access can leverage this vulnerability by configuring malicious registry credentials within Dokploy. When a swarm deployment is triggered, the compromised credentials are used in a shell command without proper sanitization, allowing the attacker to execute arbitrary operating system commands on the server. This can lead to unauthorized access, modification of host files, and lateral movement to other containers.
- Requires authenticated user with project access.
- Malicious registry credentials in shell command.
- Arbitrary OS command execution on server.
Live Threat
Current exploitation, exposure, and threat context
When supported by the advisory, an authenticated user with project access could leverage this vulnerability to execute arbitrary operating system commands on the Dokploy server. This could allow for unauthorized reading or modification of host files, and access to other containers managed by Docker.
- Arbitrary command execution on the server.
- Malicious registry credentials and swarm deployment.
- Host file modification and container access.
Operational Fix
Recommended remediation, mitigation, and detection steps
Platform-as-a-Service (PaaS) solutions like Dokploy are typically managed by infrastructure or platform teams, with application owners needing to coordinate any necessary updates or configuration changes. The immediate priority is to inventory all Dokploy instances, confirm their reachability and business criticality, and identify the precise owner responsible for each deployment. Once these steps are complete, a risk-based remediation plan can be developed, which may involve vendor coordination if the PaaS is sourced externally, or internal change management processes for self-hosted instances.
- Identify Dokploy instances and owners.
- Verify reachability and business criticality.
- Plan remediation based on identified risk.
