Finding and Exploiting .NET Remoting over HTTP using Deserialisation

Soroush Dalili · NCC Group · 19 March 2019

Servers exposing .NET Remoting over HTTP with TypeFilterLevel set to Full deserialise attacker-supplied SOAP bodies, so ysoserial.net gadgets reach code execution once the Body tags are stripped or a dummy method tag is inserted. Adds safe detection by error message, attacks on clients over unencrypted channels, a crash case, and header and encoding tricks that evade WAFs.
