CVE-2020-28494 Open this link in a new tabHow to fix?
Upgrade total.js to version 3.4.7 or higher.
Overview
total.js is a framework for Node.js platfrom written in pure JavaScript similar to PHP's Laravel or Python's Django or ASP.NET MVC. It can be used as web, desktop, service or IoT application.
Affected versions of this package are vulnerable to Command Injection. The issue occurs in the image.pipe and image.stream functions. The type parameter is used to build the command that is then executed using child_process.spawn. The issue occurs because child_process.spawn is called with the option shell set to true and because the type parameter is not properly sanitized.
PoC
const total = require('total.js');
let image = Image.load("");
let payload = ";touch HACKED;";
image.stream(payload);
// image.pipe(null, payload);
