How to fix?

There is no fixed version for onion-oled-js.

Overview

onion-oled-js is a JS library that exposes a collection of functions that wrap the oled-exp executable that controls the onion omega OLED display.

Affected versions of this package are vulnerable to Arbitrary Command Injection. If attacker-controlled user input is given to the scroll function, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization.

PoC (provided by reporter):

var OLEDExp = require('onion-oled-js').OLEDExp;

OLEDExp.scroll(';touch success #');

(A file called success will be created as a result of the execution of touch success.)
