A now-patched vulnerability affecting Oracle VM VirtualBox could be potentially exploited by an adversary to compromise the hypervisor and cause a denial-of-service (DoS) condition. "Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox," the advisory  reads . "Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DoS) of Oracle VM VirtualBox" Tracked as  CVE-2021-2442  (CVSS score: 6.0), the flaw affects all versions of the product prior to 6.1.24. SentinelLabs researcher Max Van Amerongen has been credited with discovering and reporting the issue, following which  fixes have been rolled out  by Oracle as part of its Critical Patch Update for July 2021. Oracle VM  VirtualBox  is an open-source and cross-platform hypervisor and desktop virtualization softw...

An independent exploit developer and vulnerability researcher has publicly disclosed a zero-day vulnerability in VirtualBox —a popular open source virtualization software developed by Oracle—that could allow a malicious program to escape virtual machine (guest OS) and execute code on the operating system of the host machine. The vulnerability occurs due to memory corruption issues and affects Intel PRO / 1000 MT Desktop (82540EM) network card (E1000) when the network mode is set to NAT (Network Address Translation). The flaw is independent of the type of operating system being used by the virtual and host machines because it resides in a shared code base. VirtualBox Zero-Day Exploit and Demo Video Released Sergey Zelenyuk published Wednesday a detailed technical explanation of the zero-day flaw on GitHub, which affects all current versions (5.2.20 and prior) of VirtualBox software and is present on the default Virtual Machine (VM) configuration. According to Zelenyuk, t...

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...
