1. XXE Injection:
XXE injection allows a wide range of XML based attacks, including local
file disclosure, TCP port scans and a Denial of Service (DoS) condition,
which can be achieved by recursive entity injection, attribute blow up
and other types of injection.
The following resource accessible by an unauthenticated user is
Proof of Concept (port scanning).
