Researchers Detail Privilege Escalation Bugs Reported in Oracle VirtualBox

Researchers Detail Privilege Escalation Bugs Reported in Oracle VirtualBox

Nov 23, 2021
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 software that enabl

Unpatched VirtualBox Zero-Day Vulnerability and Exploit Released Online

Nov 08, 2018
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

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte
