Open User Registration

Description:

It is possible that anyone can signup in your Freshworks Freshservice instance due to a misconfiguration in the domain allow list. Freshservice allows by default anyone to create an account on your instance.

Testing:

You can cross-check if user registration is open for anyone by navigating to the following app route:

https://<companyName>.freshservice.com/support/signup

Remediation:

Make sure to set the proper setting for new signups. One way to do so is:

1. Visit your Freshworks Freshservice Instance

2. Next, click on Admin in your side-navigation menubar

3. And search for "Support portal" and click on it

4. And finally, select the option No under "Allow users to Sign Up from the customer portal"

5. Make sure to click "Save" to save your changes.

From now on, visiting the signup app route /support/signup should return a 403 Forbidden HTTP response.

Potential Impact:

In case registrations are left open for anyone to signup to your Freshworks Freshservice instance, depending on the in-app permissions set, it could mean that new users get access to internal-only resources, such as support tickets, company metrics or even personal identifiable information (PII) of customers or clients.
