The severity of the vulnerability is rated as high (8.8) using the Common Vulnerability Scoring System, version 3.0. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor,” according to a separate security advisory, also posted Wednesday. “The issue results from the lack of proper access control. In a Wednesday security bulletin, first to widely disclose details of the bug, it was revealed that the vulnerability (CVE-2021-34864) is caused by improper access control in the Parallels’ WinAppHelper component. The flaw, according to Parallels, is specifically tied to the software’s Parallels Tools, a proxy for communications between the host macOS and the virtual machine’s operating system. The software maker stated that the recommended fixes need to be manually performed by end users and will likely “inconvenience” some while also reducing product functionality. The vulnerability allows malicious software running in a Parallels virtual machine (VM) to access macOS files shared in a default configuration of the software. Parallels Desktop, now owned by private equity giant KKR, is used by seven million users, according to the company, and allows Mac users to run Windows, Linux and other operating systems on their macOS. Mitigation advice comes five months after researchers first identified the bug in April. Grid cards are typically printed on credit card-sized plastic cards or on the back of employee access badges, credit cards or ATM cards.The makers of Parallels Desktop has released a workaround fix for a high-severity privilege escalation bug that impacts its Parallels Desktop 16 for Mac software and all older versions. On the user’s phone, the logon request will pop up and prompt the user to accept or deny by simply pressing the button.Ī grid card contains a matrix of random numbers and letters in easily marked columns and rows. When a user attempts to login, a login request is pushed out to the user via the mobile push message. OTP Card is a one-time password token in the form factor of a plastic card – the same size as a credit card or an ID card. it works like a conventional hardware OTP token – generating OTP whenever and wherever you need it, without the need for Internet or data connection. OTP app is a small software application that runs on your mobile devices and generates one-time passwords. OTP token is available in various form factors and shapes. It is very convenient and it is very secure. OTP token is a small security device that generates one-time passcodes. It’s that simple! No hardware to carry, no software to download. Once the OTP has been received and submitted by the user, the user will then be granted access. When a user attempts to login, a real-time OTP (One-Time Passcode) is sent to the user’s mobile phone via SMS text, email message or voice call. This is why Deepnet DualShield is the de facto and most popular choice for Parallels RAS customers who need multi-factor authentication. Although some other 3rd-party MFA products can be used with Parallels RAS via RADIUS, they simply can’t provide the same level of native & rich user experience and versatile MFA methods that Deepnet DualShield has delivered to the Parallels RAS users. Deepnet DualShield multi-factor authentication (MFA) component is natively built into the core of Parallels remote application server (RAS) by Parallels developers, providing strong multi-factor authentication to all Parallels RAS products with a native user interface and rich user experience. Why Deepnet DualShieldĭeepnet Security and Parallels have been technology partners for many years. With Parallels RAS, Windows applications can be used on devices that typically could not run them, including Mac & Linux computers, iOS & Android mobile devices, Google Chromebook think client and HTML5 web browser. Parallels RAS (formerly 2X) is application virtualization software that delivers centrally-hosted Windows applications to local devices without the necessity of installing them.
