Arbitrary Command Injection

killport is an a nodejs module to kill any processes base on its port

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

Running this PoC will cause the command touch success to be executed, leading to the creation of a file called success.

PoC (provided by reporter):

var killport = require('killport');
killport("$(touch success); #");

How to fix Arbitrary Command Injection?

Upgrade killport to version 1.0.2 or higher.

<1.0.2
