CVE-2024-50603: Aviatrix Controllers OS Command Injection Vulnerability

CVE-2024-50603 is an OS command injection vulnerability in Aviatrix Controllers. An unauthenticated attacker can send crafted input containing shell metacharacters to specific API endpoints and potentially execute arbitrary code on the controller. Because controllers sit at the center of multi-cloud networking, successful exploitation can give an attacker a foothold for further movement or disruption. Confirm all version and configuration details against the vendor advisory.

How it works

The flaw is classified as CWE-78 (OS Command Injection). Aviatrix Controllers expose an API at /v1/api. According to the CISA summary, shell metacharacters can be supplied in the cloud_type parameter for the list_flightpath_destination_instances action, or in the src_cloud_type parameter for the flightpath_connection_test action. When the controller processes these parameters without adequate sanitization, the injected characters can cause the underlying operating system to execute attacker-controlled commands. No authentication is required. Exact exploit mechanics and any required payload structure must be confirmed against the vendor advisory; do not rely on unvalidated public reports.

Am I affected? How to find it in your systems

Aviatrix Controllers are typically deployed as management appliances or virtual machines that orchestrate connectivity across public-cloud and hybrid environments. Inventory every instance in your estate:

• Search cloud consoles, CMDB records, and network diagrams for Aviatrix Controller hosts or related management VMs.
• Check management interfaces and API listeners that expose /v1/api.
• Compare installed software versions and configurations against the ranges listed in the vendor advisory; public detail beyond “Aviatrix Controllers” is limited here.

For signs of exploitation, review controller and reverse-proxy logs for unauthenticated requests to /v1/api that include the list_flightpath_destination_instances or flightpath_connection_test actions and that contain unusual characters in cloud_type or src_cloud_type parameters. Correlate any such requests with subsequent unexpected process creation, outbound connections, or configuration changes on the controller. Telemetry from EDR, cloud audit logs, and network IDS can surface post-exploitation activity even if the initial injection is not logged in detail.

How to remediate

Apply the mitigations or updates published by the vendor as the primary remediation. CISA’s required action is to follow the vendor instructions or discontinue use of the product if mitigations are unavailable. After patching:

• Verify that the fixed version or configuration is running on every controller.
• Re-enable only the flight-path or diagnostic features that are still required, and ensure input validation is enforced.
• Rotate any credentials or API keys that may have been accessible from the controller.
• Harden the host OS according to vendor and CIS benchmarks for this class of appliance (least-privilege service accounts, restricted shell access, timely OS patching).

Document the change and re-test the previously vulnerable API endpoints to confirm the injection path is closed.

If you can't patch immediately

Until the vendor update can be applied, reduce exposure with compensating controls:

• Network segmentation: place controllers behind management jump hosts or zero-trust gateways so that /v1/api is reachable only from authorized administrative networks.
• Virtual patching / WAF: deploy rules that block or sanitize requests containing shell metacharacters in the cloud_type and src_cloud_type parameters for the named actions.
• Feature disablement: if the flight-path diagnostic functions are not required for operations, disable them at the controller or via configuration until a permanent fix is in place.
• Heightened monitoring: alert on any unauthenticated access to /v1/api and on anomalous process or network activity originating from the controller. Retain logs for forensic review.

These measures lower risk but do not eliminate it; schedule the official remediation as soon as possible.

If your data may have been exposed

Actively exploited remote-code-execution vulnerabilities on management planes frequently lead to broader compromise and data exposure. Known ransomware use of this specific CVE is not documented. If you suspect exploitation, isolate the controller, preserve logs and memory images, and follow your incident-response plan. As a quick check for personal or organizational email addresses that may already appear in public breach data, you can run a free exposure scan of those addresses against known breach corpora.
