General

Like any good software we take security seriously. However, bugs do make it into the software along with the history of the code base we inherited. It's how we deal with identified vulnerabilities that should show that we take things seriously.

Securing your install

As with any system of this nature, we highly recommend that you restrict access to the install via a firewall or VPN.

It is also highly recommended that the Web interface is protected with an SSL certificate such as ones provided by LetsEncrypt.

When using HTTPS, it is recommended that you use secure, encrypted cookies to prevent session hijacking attacks. Set $config['secure_cookies'] = true in config.php to enable these.

Please ensure you keep your install up to date.

Reporting vulnerabilities

Like anyone, we appreciate the work people put in to find flaws in software and welcome anyone to do so with LibreNMS, this will lead to better quality and more secure software for everyone.

If you think you've found a vulnerability and want to discuss it with some of the core team then you can email us at [email protected] and we will endeavour to get back to as quick as we can, this is usually within 24 hours.

We are happy to attribute credit to the findings but we ask that we're given a chance to patch any vulnerability before public disclosure so that our users can update as soon as a fix is available.
