What it is

Reported

CtrlPanel is open-source billing software for hosting providers. In versions 1.1.1 and prior, the web-based installer (public/installer/index.php) is vulnerable to unauthenticated Remote Code Execution (RCE) because it performs the install.lock check only after including and executing form handler files, leaving installer endpoints reachable on already-installed instances. The handlers also pass unsanitized user input directly into shell commands, allowing an attacker to submit crafted requests that execute arbitrary commands on the server.… Source description excerpt; complete tracked detail loads below.
