Machine Synopsis

Cereal is a hard difficulty Windows machine with a repository exposing source code. One of the older commits is found to leak the encryption key, which can be used to login. Reviewing the code reveals deserialization and XSS vulnerabilities. These are leveraged to download a web shell and gain a foothold on the system. The user is found to have SeImpersonatePrivilege which is exploited in combination with a SSRF vulnerability to get SYSTEM privileges.
