Zyxel has released security updates to address critical flaws impacting two of its network-attached storage (NAS) devices that have currently reached end-of-life (EoL) status. Successful exploitation of three of the five vulnerabilities could permit an unauthenticated attacker to execute operating system (OS) commands and arbitrary code on affected installations. Impacted models include NAS326 running versions V5.21(AAZF.16)C0 and earlier, and NAS542 running versions V5.21(ABAG.13)C0 and earlier. The shortcomings have been resolved in versions V5.21(AAZF.17)C0 and V5.21(ABAG.14)C0, respectively. A brief description of the flaws is as follows - CVE-2024-29972 - A command injection vulnerability in the CGI program "remote_help-cgi" that could allow an unauthenticated attacker to execute some operating system (OS) commands by sending a crafted HTTP POST request CVE-2024-29973 - A command injection vulnerability in the 'setCookie' parameter that could allow a...

In 2017, The Australian Cyber Security Center (ACSC) published a set of mitigation strategies that were designed to help organizations to protect themselves against cyber security incidents. These strategies, which became known as  the Essential Eight , are designed specifically for use on Windows networks, although variations of these strategies are commonly applied to other platforms. What is the Essential Eight?  The Essential Eight is essentially a cyber security framework that is made up of objectives and controls (with each objective including multiple controls). Initially, the Australian government only mandated that companies adhere to four of the security controls that were included in the first objective. Starting in June of 2022 however, all 98 non-corporate Commonwealth entities (NCCEs) are going to be  required to comply with the entire framework . Non-Australians take note  Although the Essential Eight is specific to Australia, organizations outsid...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Everyone makes mistakes. That one sentence was drummed into me in my very first job in tech, and it has held true since then. In the cybersecurity world, misconfigurations can create exploitable issues that can haunt us later - so let's look at a few common security misconfigurations. The first one is development permissions that don't get changed when something goes live. For example, AWS S3 buckets are often assigned permissive access while development is going on. The issues arise when security reviews aren't carefully performed prior to pushing the code live, no matter if that push is for the initial launch of a platform or for updates. The result is straight-forward; a bucket goes live with the ability for anyone to read and write to and from it. This particular misconfiguration is dangerous; since the application is working and the site is loading for users, there's no visible indication that something is wrong until a threat actor hunting for open buckets stum...
