cPanel SSH and terminal access restricted on cPanel and home.snt

-- TLDR; Because of a Linux kernel vulnerability that got discovered, SNT had to restrict ssh access for all customers and almost all active members. You can track this issue here. --

A new Linux kernel 0-day had just been released (https://github.com/0xdeadbeefnetwork/ssh-keysign-pwn/). There are no patches available as of writing in any distro of Linux or any kernel version. This meant that SNT had to restrict the Terminal/SSH access feature in cPanel and WHM as a safety measure. We will reenable this feature as soon as it seems safe to us to do so again.

We are closely monitoring the development of this 0-day and will notify you as soon as we know more here.

All websites and other services hosted by SNT will continue to function normally and securely. It does not seem that this 0-day has been exploited yet.

  • Hornet, Pydio, and home.snt all received security patches as well. Therefore, Pydio and Hornet will also take part in the maintenance window scheduled tonight. I apologize for the inconvenience. We will monitor whether it is safe to turn terminal functionality back on in cPanel after the maintenance. You can find updates about this here.

    The home.snt machine got rebooted as well, so active members may make use of that machine again.

  • cPanel received security patches, and will have short security maintenance today at 11:00 PM (Europe/Amsterdam). Afterwards, the SSH feature will be enabled if we think it is secure to do so.

    • Maintenance
    Hornet security maintenance

    Following the recent Linux Kernel local privilege escalation "ssh-keysign-pwn", we will perform short maintenance on the Hornet platform. The security mitigation had already been applied, so services and websites continue to function securely before the maintenance. See also: https://status.snt.utwente.io/incidents/89

    cPanel, Pydio, the Hornet dashboard and all websites hosted by SNT will be unavailable for a short amount of time.

    cPanel cPanel limited availability

    Because of an ongoing security vulnerability mitigation, cPanel has limited to no availability of components like webmail, admin, etc, as certain components of cPanel are currently disabled. We are monitoring updates from the cPanel security team closely and will post updates once services will become available again.

    Websites hosted by cPanel are not affected in availability and should continue to work securely.

  • All systems are operational and function as normal again. No data seems to have been lost.

  • Fixes have been implemented, continuing to monitor while services recover.

  • cPanel just released a patch, we are implementing the fix and are going to monitor the services afterwards.

    GitLab runners GitLab CI runners unavailable

    During maintenance an issue occurred with the GitLab CI Runner server.

    Cloud Cloud node unresponsive

    One of the cloud nodes has become unresponsive to commands. We're trying to resolve this issue with as little downtime as possible.

  • The cloud node is responsive again, but will require an update to be fully operational. Customers with a VM on ‘kletsmajoor’ are asked to fully shut down their VM and start it again at their earliest convenience.
