Overview
backpack/crud is a package that helps you build an admin interface for your Eloquent models, using Laravel 5
Affected versions of this package are vulnerable to Improper Encoding or Escaping of Output via the makeCurlRequest function. An attacker can execute arbitrary operating system commands as the web server user by supplying a specially crafted Host header that is incorporated into a shell command without proper sanitization. This is only exploitable if both the web server and PHP configurations allow unfiltered Host headers to reach the application and the exec() function is enabled for web processes.
