Package	Affected versions	Patched versions
portprocesses portprocesses_project	`< 1.0.5`	`1.0.5`
portprocesses npm	`< 1.0.5`	`1.0.5`

Description

Impact

An Arbitrary Command Injection vulnerability was reported in portprocesses impacting versions <= 1.0.4.

Example (Proof of Concept)

The following example demonstrates the vulnerability and will run touch success therefore creating a file named success.

const portprocesses = require("portprocesses");

portprocesses.killProcess("$(touch success)");

NVD description

This affects the package portprocesses before 1.0.5. If (attacker-controlled) user input is given to the killProcess 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.
