Vulnerability Details : CVE-2019-11409

app/operator_panel/exec.php in the Operator Panel module in FusionPBX 4.4.3 suffers from a command injection vulnerability due to a lack of input validation that allows authenticated non-administrative attackers to execute commands on the host. This can further lead to remote code execution when combined with an XSS vulnerability also present in the FusionPBX Operator Panel module.

FusionPBX Operator Panel exec.php Command Execution
This module exploits an authenticated command injection vulnerability in FusionPBX versions 4.4.3 and prior. The `exec.php` file within the Operator Panel permits users with `operator_panel_view` permissions, or administrator permissions, to execute arbitrary commands as the web server user by sending a `system` command to the FreeSWITCH event socket interface. This module has been tested successfully on FusionPBX version 4.4.1 on Ubuntu 19.04 (x64).
