Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
Stability:
- crash-safe: Module should not crash the service.
Basic Usage
There are two ways to execute this post module.
From the Meterpreter prompt
The first is by using the "run" command at the Meterpreter prompt. It allows you to run the post module against that specific session:
meterpreter > run post/multi/recon/reverse_lookup
From the msf prompt
The second is by using the "use" command at the msf prompt. You will have to figure out which session ID to set manually. To list all session IDs, you can use the "sessions" command.
msf > use post/multi/recon/reverse_lookup
msf post(reverse_lookup) > show options
... show and set options ...
msf post(reverse_lookup) > set SESSION session-id
msf post(reverse_lookup) > exploit
If you wish to run the post against all sessions from framework, here is how:
1 - Create the following resource script:
framework.sessions.each_pair do |sid, session|
run_single("use post/multi/recon/reverse_lookup")
run_single("set SESSION #{sid}")
run_single("run")
end
2 - At the msf prompt, execute the above resource script:
msf > resource path-to-resource-script
Required Options
- SESSION: The session to run this module on
Knowledge Base
Vulnerable Application
This module reverse resolves an IP address or IP address range to hostnames.
Verification Steps
- Start msfconsole
- Get a session
- Do:
use post/multi/recon/reverse_lookup - Do:
set SESSION <session id> - Do:
set ADDRESS <IP address>orset RANGE <IP address range> - Do:
run
Options
ADDRESS
IP address to resolve.
RANGE
IP address range to resolve.
Scenarios
Windows Server 2016 (x86_64)
msf6 > use post/multi/recon/reverse_lookup
msf6 post(multi/recon/reverse_lookup) > set address 1.1.1.1
address => 1.1.1.1

session => 1
msf6 post(multi/recon/reverse_lookup) > run
[*] Resolving 1.1.1.1
[+] 1.1.1.1 resolves to one.one.one.one
[*] Post module execution completed

msf6 post(multi/recon/reverse_lookup) > run
[!] SESSION may not be compatible with this module:
[!] * missing Meterpreter features: stdapi_railgun_memread, stdapi_railgun_api
[*] Resolving 1.1.1.1
[+] 1.1.1.1 resolves to one.one.one.one
