CVE-2021-23377 Open this link in a new tabHow 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.)
