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.

Every year, thousands of new vulnerabilities are discovered, requiring organizations to patch operating systems (OS) and applications and reconfigure security settings throughout the entirety of their network environment. To proactively address vulnerabilities before they are utilized for a cyberattack, organizations serious about the security of their environment perform vulnerability management to provide the highest levels of security posture possible.

In the world of vulnerabilities, we have seen a few interesting ones released in the last couple of weeks since our last Farsight risk-based vulnerability management blog in June, including some recently discovered by Palo Alto affecting D-Link Routers. Read on for more information on how to prioritize these vulnerabilities for patching to mitigate risk.

Vulnerability management is the process of finding, assessing, remediating and mitigating security weaknesses. The vulnerability management process has as one of its main phases the vulnerability assessment, the step where vulnerabilities in the assets in scope are identified.

It’s time for June’s open source vulnerabilities snapshot, your monthly overview of everything new in the fast-paced world of open source security vulnerabilities. In hopes of giving you this month-at-a-glance summary of current trends in the open source ecosystem, our trusted research team reviewed the new open source security vulnerabilities published in May and collected by the WhiteSource database.
