Full stack development is all the rage these days, and for good reason: developers with both front-end web development skills and back-end/server coding prowess clearly offer substantially more value to their respective organizations. The ability to traverse the entire stack competently also makes interacting and cooperating with operations and security an easier affair—a key tenet of DevOps culture.
An Elastic Security Advisory (ESA) is a notice from Elastic to its users of a new Elasticsearch vulnerability. The vendor assigns both a CVE and an ESA identifier to each advisory along with a summary and remediation details. When Elastic receives an issue, they evaluate it and, if the vendor decides it is a vulnerability, work to fix it before releasing a remediation in a timeframe that matches the severity.
While auditing the Kubernetes source code, I recently discovered an issue (CVE-2020-8563) in Kubernetes that may cause sensitive data leakage. You would be affected by CVE-2020-8563 if you created a Kubernetes cluster over vSphere, and enabled vSphere as a cloud provider with logging level set to 4 or above. In that case, your vSphere user credentials will be leaked in the cloud-controller-manager‘s log.
A critical Active Directory vulnerability (CVE-2020-1472) has been making headlines for being the most notorious elevation of privilege bug because it can affect all computers and domain controllers in an organization. This high-risk vulnerability, dubbed Zerologon, gives threat actors easy, instant access to domain controllers without requiring any additional privileges. This attack does not even require a user to be authenticated; the user just needs to be connected to the internal network.
This time around, the MySQL vulnerabilities caught our attention because of their low CVSS scores compared to their high likelihood risk rating. This is something we see often when working with our customers, and demonstrates how a risk based approach to vulnerability management changes as organizations focus on where there is a real risk of compromise.
Every day we discover new vulnerabilities in our systems, cracks in the fence the adversaries take advantage of to get into your organization and wreak havoc. Understanding what you have in your environment (e.g., types of devices, systems equipment, etc.) is very important in order to make sure the controls in place are working and more importantly, keeping up with the threat landscape.
Today, we released a Threat Definition Update bundle for our Tripwire Industrial Visibility solution to aid in the detection of Zerologon. Otherwise known as CVE-2020-1472, Zerologon made news in the summer of 2020 when it received a CVSSv3 score of 10—the most critical rating of severity. Zerologon is a vulnerability that affects the cryptographic authentication mechanism used by the Microsoft Windows Netlogon Remote Protocol (MS-NRPC), a core authentication component of Active Directory.
Since the global pandemic we’ve been writing about the latest CVEs to look out for in our risk based vulnerability management blog. As we head into the Autumn and the nights begin to draw in, threat actors continue to exploit vulnerabilities and cause disruption. Let’s take a look at some that have raised their profile in the last couple of weeks
