CVE-2021-23375 Open this link in a new tabHow to fix?
There is no fixed version for psnode.
Overview
psnode is an A Node.js KISS module to list and kill process on OSX and Windows.
Affected versions of this package are vulnerable to Arbitrary Command Injection. If attacker-controlled user input is given to the kill 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 psnode = require('psnode');
psnode.kill('$(touch success)', function() {});
(A file called success will be created as a result of the execution of touch success.)
