Vulnerability scans of the ACOS management interface have shown ISAKMP/IKE (Internet Security Association and Key Management Protocol/Internet Key Exchange) UDP ports to be open when no IKE-based VPNs were configured for A10 Thunder and AX devices.
This behavior does not represent a security risk or exposure in the ACOS system, as received packets on UDP ports 500, 4500, and 4510 will be ignored in such cases. To avoid false reporting of potential ACOS vulnerabilities in this regard, the behavior will be corrected as described further in this document.
