Remember that high school teacher who was never more than one chapter ahead of their students? Well that is me, in this blog. ¯\_(ツ)_/¯

Vulnerabilities are weaknesses leveraged by adversaries to compromise the confidentiality, availability or integrity of a resource. The vulnerability ecosystem has matured considerably in the last few years. A significant amount of effort has been invested to capture, curate, taxonomize and communicate the vulnerabilities in terms of severity, impact and complexity of the associated exploit or attack.

In the world of CVEs, we have seen a few interesting ones released in the last couple of weeks since our last risk based vulnerability management blog, including the recent big news SIGRed. Read on for more information on how to prioritize these vulnerabilities for patching to mitigate risk.

On July 14, 2020, Microsoft released a security update related to a remote code execution (RCE) and denial of service (DoS) vulnerability (CVE-2020-1350) in Windows DNS Server (2003 - 2019).

In the world of CVEs, we have seen a few interesting ones released in the last couple of weeks since our last risk based vulnerability management blog, including the recent big news items affecting F5 BIGIP and Pan-OS. Read on for more information on how to prioritize these vulnerabilities for patching to mitigate risk.

This blog was written by a third party author Vulnerability scanning is the process of detecting and classifying potential points of exploitation in network devices, computer systems, and applications. This is done by inspecting the same attack areas used by both internal and external threat actors—such as firewalls, applications, and services that are deployed either internally or externally—to gain unauthorized access to an organization’s network and assets.

A new vulnerability, CVE-2020-8557, has been detected in kubelet. It can be exploited by writing into /etc/hosts to cause a denial of service. The source of the issue is that the /etc/hosts file mounted in a pod by kubelet is not included by the kubelet eviction manager, so it’s not taken into account when calculating ephemeral storage usage by a pod.

A misconfiguration is exactly what it sounds like; something that is wrongly configured. From a security perspective this can be either fairly harmless, or in the worst case devastating. We have written about misconfigurations before, both here and here. Misconfigurations may derive from many different reasons, such as: Hackers often exploit misconfigurations, since this can have a huge security impact.

I’ve worked in the IT field for over 30 years. 20 of those years have been spent in the network security field, employed by some of the largest names in the industry. But to my family, I’m still just the guy who “works with computers”. Many of my family are not computer savvy, which is a nice way of saying I had to teach them where the power button is. However, “Power Button Locator” is just one of my jobs. Windows won’t boot up?

As our R&D team develops Rezilion, they occasionally see opportunities to improve and inform the status quo. In this post, our Team Lead, Yuri Shafet, spends some time diving into ptrace — what it is, how to use it to inject arbitrary code into a running process, how to limit ptrace execution and different techniques to dynamically detect it.
