Description

This module exploits a .NET deserialization vulnerability in the Veeam
ONE Agent before the hotfix versions 9.5.5.4587 and 10.0.1.750 in the
9 and 10 release lines.

Specifically, the module targets the HandshakeResult() method used by
the Agent. By inducing a failure in the handshake, the Agent will
deserialize untrusted data.

Tested against the pre-patched release of 10.0.0.750. Note that Veeam
continues to distribute this version but with the patch pre-applied.
