It's time to gear up for the latest May 2018 Patch Tuesday. Microsoft has today released security patches for a total of 67 vulnerabilities, including two zero-days that have actively been exploited in the wild by cybercriminals, and two publicly disclosed bugs. In brief, Microsoft is addressing 21 vulnerabilities that are rated as critical, 42 rated important, and 4 rated as low severity. These patch updates address security flaws in Microsoft Windows, Internet Explorer, Microsoft Edge, Microsoft Office, Microsoft Office Exchange Server, Outlook, .NET Framework, Microsoft Hyper-V, ChakraCore, Azure IoT SDK, and more. 1) Double Kill IE 0-day Vulnerability The first zero-day vulnerability ( CVE-2018-8174 ) under active attack is a critical remote code execution vulnerability that was revealed by Chinese security firm Qihoo 360 last month and affected all supported versions of Windows operating systems. Dubbed " Double Kill " by the researchers, the vulnera

Since hackers have started exploiting two recently disclosed unpatched critical vulnerabilities found in GPON home routers, security researchers have now released an unofficial patch to help millions of affected users left vulnerable by their device manufacturer. Last week, researchers at vpnMentor disclosed details of—an authentication bypass (CVE-2018-10561) and a root-remote code execution vulnerability (CVE-2018-10562)—in many models of Gigabit-capable Passive Optical Network (GPON) routers manufacturer by South Korea-based DASAN Zhone Solutions. If exploited, the first vulnerability lets an attacker easily bypass the login authentication page just by appending ?images/ to the URL in the browser's address bar. However, when coupled with the second flaw that allows command injection, unauthenticated attackers can remotely execute malicious commands on the affected device and modified DNS settings, eventually allowing them to take full control of the device remotely.

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

A team of security researchers has reportedly discovered a total of eight new " Spectre-class " vulnerabilities in Intel CPUs, which also affect at least a small number of ARM processors and may impact AMD processor architecture as well. Dubbed Spectre-Next Generation , or Spectre-NG , the partial details of the vulnerabilities were first leaked to journalists at German computer magazine Heise, which claims that Intel has classified four of the new vulnerabilities as "high risk" and remaining four as "medium." The new CPU flaws reportedly originate from the same design issue that caused the original Spectre flaw , but the report claims one of the newly discovered flaws allows attackers with access to a virtual machine (VM) to easily target the host system, making it potentially more threatening than the original Spectre vulnerability. "Alternatively, it could attack the VMs of other customers running on the same server. Passwords and secret k

Just a few days prior to its monthly patch release, Microsoft released an emergency patch for a critical vulnerability in the Windows Host Compute Service Shim (hcsshim) library that could allow remote attackers to run malicious code on Windows computers. Windows Host Compute Service Shim (hcsshim) is an open source library that helps "Docker for Windows" execute Windows Server containers using a low-level container management API in Hyper-V. Discovered by Swiss developer and security researcher Michael Hanselmann , the critical vulnerability (tracked as CVE-2018-8115) is the result of the failure of the hcsshim library to properly validate input when importing a Docker container image. This, in turn, allows an attacker to remotely execute arbitrary code on the Windows host operating system, eventually letting the attacker create, remove, and replace files on the target host. As Hanselmann explained  in his personal blog, "Importing a Docker container image or

Earlier this month, Oracle patched a highly critical Java deserialization remote code execution vulnerability in its WebLogic Server component of Fusion Middleware that could allow attackers to easily gain complete control of a vulnerable server. However, a security researcher, who operates through the Twitter handle @pyn3rd and claims to be part of the Alibaba security team, has now found a way using which attackers can bypass the security patch and exploit the WebLogic vulnerability once again. WebLogic Server acts as a middle layer between the front end user interface and the backend database of a multi-tier enterprise application. It provides a complete set of services for all components and handles details of the application behavior automatically. Initially discovered in November last year by Liao Xinxi of NSFOCUS security team, the Oracle WebLogic Server flaw (CVE-2018-2628) can be exploited with network access over TCP port 7001. If exploited successfully, the fl
