List of CVEs: CVE-2022-0824
In Webmin version 1.984, any authenticated low privilege user without access rights to the File Manager module could interact with file manager functionalities such as downloading files from remote URLs and changing file permissions. It is possible to achieve Remote Code Execution via a crafted .cgi file by chaining those functionalities in the file manager.
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
msf > use exploit/linux/http/webmin_file_manager_rce
msf exploit(webmin_file_manager_rce) > exploit
Required Options
- RHOSTS: The target host(s), see https://github.com/rapid7/metasploit-framework/wiki/Using-Metasploit
Knowledge Base
Vulnerable Application
In Webmin v1.984, any authenticated low privilege user without access rights to the File Manager module could interact with file manager functionalities such as downloading files from remote URLs and changing file permissions (chmod). It is possible to achieve Remote Code Execution via a crafted .cgi file by chaining those functionalities in the file manager.
Setup, on Ubuntu 20.04
wget https://download.webmin.com/devel/deb/webmin_1.984_all.deb
sudo dpkg -i webmin_1.984_all.deb
Webmin should now be installed. The credentials for the web UI will be the same as the user that installed Webmin
Options
USERNAME
A specific username to authenticate as
PASSWORD
A specific password to authenticate with
Verification Steps
- Start msfconsole
- Do:
use exploit/linux/http/webmin_file_manager_rce - Set the
RHOST,USERNAME, andPASSWORDoptions - Run the module
- Receive a session as the
rootuser.
