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

CVE-2020-14386 is yet another severe vulnerability that was recently discovered in the Linux kernel. It reminds us that the fight against vulnerabilities is not over. This particular one allows a regular application to escalate its privileges and gain root access to the machine. Indeed, it sounds scary.

Zerologon (CVE-2020-1472) is a critical vulnerability in the Windows Server Netlogon process authentication process. Following our recent Security Advisory, immediate patching of the vulnerability is strongly advised. To help determine whether your organisation has been compromised as a result of an attacker exploiting the vulnerability (even prior to a patch being installed), Redscan Labs has developed a Zerologon detection tool.

A critical vulnerability in Instagram’s Android and iOS apps could have allowed remote attackers to run malicious code, snoop on unsuspecting users, and hijack control of smartphone cameras and microphones. The security hole, which has been patched by Instagram owner Facebook, could be exploited by a malicious hacker simply sending their intended victim a boobytrapped malicious image file via SMS, WhatsApp, email or any other messaging service.

Containers have become very popular with DevOps as a way to increase speed and agility. However, with recent reports of hackers utilizing vulnerabilities in Docker container images to compromise hosts and launch malicious containers – how can we identify this at the time of development to prevent security costing us later?

When investing in an application security (AppSec) program, you expect to see a return on your investment. But in order to recognize a return, your organization needs to determine what success looks like and find a way to measure and prove that the program is meeting your definition of success.

A critical CVSS:10 vulnerability (CVE-2020-1472) in the Microsoft Netlogon process was patched in the August patch cycle, but details were not made public until earlier this week (14th September).

The recent disclosure of CVE-2020-1472 vulnerability by Microsoft showcases the need for tools that allow defenders to quickly replicate published exploit code, register attack data, and create signatures or other mitigations against released exploits with a high likelihood of exploitation against popular infrastructure or operating systems.
