Machine Synopsis

StreamIO is a medium machine that covers subdomain enumeration leading to an SQL injection in order to retrieve stored user credentials, which are cracked to gain access to an administration panel. The administration panel is vulnerable to LFI, which allows us to retrieve the source code for the administration pages and leads to identifying a remote file inclusion vulnerability, the abuse of which gains us access to the system. After the initial shell we leverage the SQLCMD command line utility to enumerate databases and obtain further credentials used in lateral movement. As the secondary user we use `WinPEAS` to enumerate the system and find saved browser databases, which are decoded to expose new credentials. Using the new credentials within BloodHound we discover that the user has the ability to add themselves to a specific group in which they can read LDAP secrets. Without direct access to the account we use PowerShell to abuse this feature and add ourselves to the `Core Staff` group, then access LDAP to disclose the administrator LAPS password.
