Overview

ps-kill is a Kill processes with ease

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 in the index.js file.

PoC (provided by reporter):

var ps_kill = require('ps-kill');

ps_kill.kill('$(touch success)',function(){});
