Executive Technical Summary

VMware NSX SD-WAN Edge by VeloCloud prior to version 3.1.0 contains a command injection vulnerability in the local web UI component. This component is disabled by default and should not be enabled on untrusted networks. VeloCloud by VMware will be removing this service from the product in future releases. Successful exploitation of this issue could result in remote code execution.

• Context preserved from previous revision: VMware NSX SD-WAN Edge by VeloCloud prior to version 3.1.0 contains a command injection vulnerability in the local web UI component. This component is disabled by default and should not be enabled on untrusted networks. VeloCloud by VMware will be removing this service from the product in future releases. Successful exploitation of this issue could result in remote code execution. Notes: Ostorlab KEV: One-command to detect most remotely known exploitable vulnerabilities.

Practical Defensive Validation (Authorized Only)

1. Use only isolated environments and systems you own or are explicitly authorized to test.
2. Snapshot infrastructure before validation and preserve baseline logs (EDR, SIEM, OS, app).
3. Use vmware / nsx sd-wan by velocloud (versions: < 3.1.0) in isolated VM snapshots (vulnerable vs patched) and compare process tree telemetry before/after updates.
4. Validate command-execution prevention policies (AppLocker/WDAC/EDR) with harmless test binaries only.
5. Create SIEM detections for suspicious parent-child chains, encoded command usage, and abnormal service creation.
