| ## Vulnerable Application | ||
|
|
||
| A Command Injection vulnerability in Artica Proxy appliance version `4.50` and `4.40` | ||
| allows remote attackers to run arbitrary commands via unauthenticated HTTP request. | ||
| The Artica Proxy administrative web application will de-serialize arbitrary PHP objects | ||
| supplied by unauthenticated users and subsequently enable code execution as the `www-data` user. | ||
|
|
||
| This module has been tested with: | ||
| * Artica Proxy Appliance 4.50 running in VirtualBox 7.0.14 r161095 (Qt5.15.2) | ||
| * Artica Proxy Appliance 4.40 Service Pack 118 running in VirtualBox 7.0.14 r161095 (Qt5.15.2) | ||
|
|
||
| ## Installation steps to install Artica Proxy appliance | ||
| * Install your favorite virtualization engine (VMware or VirtualBox) on your preferred platform. | ||
| * Here are the installation instructions for [VirtualBox on MacOS](https://tecadmin.net/how-to-install-virtualbox-on-macos/). | ||
| * Download the Artica Proxy iso image from [here](https://sourceforge.net/projects/artica-squid/files/ISO/). | ||
| * Install the iso image in your virtualization engine. | ||
| * When installed, configure the VM appliance to your needs using the menu options. | ||
| * Boot up the VM and should be able to access the Artica appliance. | ||
| * Either thru the console, `ssh` on port `22` or via the `webui` via `https://your_articaproxy_ip:9000`. | ||
|
|
||
| You are now ready to test the module. | ||
|
|
||
| ## Verification Steps | ||
|
|
||
| - [ ] Start `msfconsole` | ||
| - [ ] `use exploit/linux/http//artica_proxy_unauth_rce_cve_2024_2054` | ||
| - [ ] `set rhosts <ip-target>` | ||
| - [ ] `set rport <port>` | ||
| - [ ] `set webshell cuckoo` | ||
| - [ ] `set target <0=PHP, 1=Unix Command, 2=Linux Dropper>` | ||
| - [ ] `exploit` | ||
| - [ ] you should get a `reverse shell` or `Meterpreter` session depending on the `payload` and `target` settings | ||
|
|
||
| ## Options | ||
|
|
||
| ### WEBSHELL | ||
| You can use this option to set the filename without extension of the webshell. | ||
| This is handy if you want to test the webshell upload and execution with different file names. | ||
| to bypass any security settings on the Web and PHP server. | ||
|
|
||
| ### COMMAND | ||
| This option provides the user to choose the PHP underlying shell command function to be used for execution. | ||
| The choices are `system()`, `passthru()`, `shell_exec()` and `exec()` and it defaults to `passthru()`. | ||
| This option is only available when the target selected is either Unix Command or Linux Dropper. | ||
| For the native PHP target, by default the `eval()` function will be used for native PHP code execution. | ||
