CVE: [CVE-2020-5847](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-5847>)
### Background
[Unraid](<https://unraid.net/>) is a network-attached storage operating system. It runs a web-based graphical user interface (webGui) written in PHP.
### Problem
The Unraid webGui uses the PHP `**extract**` function to load all GET parameters into the application as variables, allowing a remote user to control any program variable, leading to command execution.
### Resolution
Upgrade to [Unraid](<https://unraid.net/>) 6.8.1 or higher.
