List of CVEs: CVE-2020-27386
This module exploits an arbitrary file upload vulnerability
in FlexDotnetCMS v1.5.8 and prior in order to execute
arbitrary commands with elevated privileges. The module
first tries to authenticate to FlexDotnetCMS via an HTTP
POST request to /login. It then attempts to upload a
random TXT file and subsequently uses the FlexDotnetCMS file
editor to rename the TXT file to an ASP file. If this
succeeds, the target is vulnerable and the ASP file is
generated as a copy of the TXT file, which remains on the
server. Next, the module sends another request to rename the
TXT file to an ASP file, this time adding the payload.
Finally, the module tries to execute the ASP payload via a
simple HTTP GET request to /media/uploads/asp_payload
Valid credentials for a FlexDotnetCMS user with permissions
to use the FileManager are required. This module has been
successfully tested against FlexDotnetCMS v1.5.8 running on
Windows Server 2012.
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 flexdotnetcms_upload_exec against a single host
Normally, you can use exploit/windows/http/flexdotnetcms_upload_exec this way:
msf > use exploit/windows/http/flexdotnetcms_upload_exec
msf exploit(flexdotnetcms_upload_exec) > show targets
... a list of targets ...
msf exploit(flexdotnetcms_upload_exec) > set TARGET target-id
msf exploit(flexdotnetcms_upload_exec) > show options
... show and set options ...
msf exploit(flexdotnetcms_upload_exec) > exploit
Using flexdotnetcms_upload_exec 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 flexdotnetcms_upload_exec 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/windows/http/flexdotnetcms_upload_exec")
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.

Knowledge Base
Vulnerable Application
This module exploits an arbitrary file upload vulnerability (CVE-2020-27386) in FlexDotnetCMS v1.5.8 and prior in order to execute arbitrary commands with elevated privileges.
The module first tries to obtain various tokens required for authentication from /login.
Next, the module tries to authenticate via an HTTP POST request to the same destination followed by an HTTP GET request to /Admin.
If authentication is successful, the module uploads a TXT file containing a random string via an HTTP POST request to
/Scripts/tinyfilemanager.net/dialog.aspx.
The module then loads the uploaded TXT file in the file editor in order to obtain tokens necessary for renaming the TXT file.
It then tries to rename the TXT file to an ASP file via an HTTP POST request to /Admin/Views/PageHandlers/FileEditor/Default.aspx.
If this succeeds, the target is vulnerable and the ASP file is generated as a copy of the TXT file, which remains on the server.
Next, the module sends another request to the file editor to rename the TXT file to an ASP file, this time adding the payload.
The module will execute the payload via a simple HTTP GET request to /media/uploads/asp_payload.
Finally, the module will try to delete both the uploaded TXT file and the ASP copy from the target.
Valid credentials for a FlexDotnetCMS user with permissions to use the FileManager are required. This attack will normally result in remote code execution with administrator privileges, because the attacker will inherit the privileges of the IIS/IIS Express process, which must run with elevated privileges if configured to allow remote connections. This module has been successfully tested against FlexDotnetCMS v1.5.8 running on Windows Server 2012.
Vulnerable software for testing is available on GitHub here. Detailed installation instructions are available here. As the instructions mention, FlexDotnetCMS requires the following dependencies: - .NET Framework 4.5.2 - Visual Studio 2015 (Free Community Edition works) - MS SQL Server (Express) 2012 + - IIS (Express) 8 +
