Stopping Drupal’s SA-CORE-2019-003 Vulnerability

Stopping Drupal’s SA-CORE-2019-003 Vulnerability

On the 20th February 2019, Drupal announced that they had discovered a severe vulnerability and that they would be releasing a patch for it the next day. Drupal is a Content Management System used by many of our customers, which made it important that our WAF protect against the vulnerability as quickly as possible.

As soon as Drupal released their patch, we analysed it to establish what kind of payloads could be used against it and created rules to mitigate these. By analysing the patch we were able to put together WAF rules to protect cloudflare customers running Drupal.

We identified the type of vulnerability we were dealing within 15 minutes. From here, we were able to deploy rules to block the exploit well before any real attacks were seen.

The exploit

As Drupal's release announcement explains, a site is affected if:

  • It has the Drupal 8 RESTful API enabled                                      
  • Or it uses one of the 8 modules found to be affected

From looking at the patch we very quickly realised the exploit would be based on deserialization. The option ['allowed_classes' Continue reading

4 Tips for Easier Edge Deployments

There are plenty of reasons for organizations to embrace edge computing. By moving applications, data, and computing services to the edge of a network, as opposed to a large data center or cloud, organizations can lower operating costs, improve application performance, reduce network traffic, and achieve real-time data analytics.As more organizations come to know the advantages of edge of network devices, many are eyeing deployments. In fact, according to the IDG 2018 State of the Network, 56% of networking professionals have plans for edge computing in their organizations.To read this article in full, please click here

How to configure a static IP address on Linux

IP addresses on Linux systems are often assigned automatically by Dynamic Host Configuration Protocol (DHCP) servers. These are referred to as "dynamic addresses" and may change any time the system is rebooted. When a system is a server or will be remotely administered, however, it is generally more convenient for these systems to have static addresses, providing stable and consistent connections with users and applications.Fortunately, the steps required to change a Linux system's IP address from dynamic to static are fairly easy, though they will be a little different depending on the distribution you are using. In this post, we'll look at how this task is managed on both Red Hat (RHEL) and Ubuntu systems.To read this article in full, please click here
