DHS Orders Federal Agencies to Patch Critical Flaws Within 15 Days

DHS Orders Federal Agencies to Patch Critical Flaws Within 15 Days

May 01, 2019
In recent years, we have seen how hackers prey on those too lazy or ignorant to install security patches, which, if applied on time, would have prevented some devastating cyber attacks and data breaches that happened in major organisations. The United States Department of Homeland Security (DHS) has ordered government agencies to more swiftly plug the critical security vulnerabilities found on their networks within 15 calendar days since the initial detection, a reduction from 30 days. DHS's Cybersecurity and Infrastructure Security Agency (CISA) this week issued a new Binding Operational Directive (BOD) 19-02 instructing federal agencies and departments to address "critical" rated vulnerabilities within 15 days and "high" severity flaws within 30 days of initial detection. The countdown to patch a security vulnerability will start when it was initially detected during CISA's weekly Cyber Hygiene vulnerability scanning, rather than it was the firs

Adobe Releases Patches for Critical Flaws in Photoshop CC and Digital Edition

Mar 12, 2019
Adobe users would feel lighter this month, as Adobe has released patches for just two security vulnerability in its March Security Update. The company today released its monthly security updates to address two critical arbitrary code execution vulnerabilities—one in Adobe Photoshop CC and another in Adobe Digital Editions. Upon successful exploitation, both critical vulnerabilities could allow an attacker to achieve arbitrary code execution in the context of the current user and take control of an affected system. However, the good news is that the company found no evidence of any exploits in the wild for these security issues, Adobe said. The vulnerability in Adobe Photoshop CC , discovered by Trend Micro Zero Day Initiative and assigned CVE-2019-7094, is a heap corruption issue which affects Photoshop CC 19.1.7 and earlier 19.x versions as well as Photoshop CC 20.0.2 and earlier 20.x versions for Microsoft Windows and Apple macOS operating systems.

A Simple Tool Released to Protect Dasan GPON Routers from Remote Hacking

May 08, 2018
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.
Microsoft Issues Emergency Patch For Critical Flaw In Windows Containers

Microsoft Issues Emergency Patch For Critical Flaw In Windows Containers

May 03, 2018
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
Faulty Patch for Oracle WebLogic Flaw Opens Updated Servers to Hackers Again

Faulty Patch for Oracle WebLogic Flaw Opens Updated Servers to Hackers Again

Apr 30, 2018
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

WordPress Update Breaks Automatic Update Feature—Apply Manual Update

Feb 09, 2018
WordPress administrators are once again in trouble. WordPress version 4.9.3 was released earlier this week with patches for a total 34 vulnerabilities, but unfortunately, the new version broke the automatic update mechanism for millions of WordPress websites. WordPress team has now issued a new maintenance update, WordPress 4.9.4 , to patch this severe bug, which WordPress admins have to install manually. According to security site WordFence , when WordPress CMS tries to determine whether the site needs to install an updated version, if available, a PHP error interrupts the auto-update process. If not updated manually to the latest 4.9.4 version, the bug would leave your website on WordPress 4.9.3 forever, leaving it vulnerable to future security issues. Here's what WordPress lead developer Dion Hulse explained about the bug: "#43103-core aimed to reduce the number of API calls which get made when the auto-update cron task is run. Unfortunately, due to human e
Intel Releases New Spectre Patch Update for Skylake Processors

Intel Releases New Spectre Patch Update for Skylake Processors

Feb 08, 2018
After leaving million of devices at risk of hacking and then rolling out broken patches, Intel has now released a new batch of security patches only for its Skylake processors to address one of the Spectre vulnerabilities (Variant 2). For those unaware, Spectre ( Variant 1, Variant 2 ) and Meltdown ( Variant 3 ) are security flaws disclosed by researchers earlier last month in processors from Intel, ARM, and AMD, leaving nearly every PC, server, and mobile phone on the planet vulnerable to data theft. Shortly after the researchers disclosed the Spectre and Meltdown exploits , Intel started releasing microcode patches for its systems running Broadwell, Haswell, Skylake, Kaby Lake, and Coffee Lake processors. However, later the chip maker rollbacked the firmware updates and had to tell users to stop using an earlier update due to users complaining of frequent reboots and other unpredictable system behavior after installing patches. Although it should be a bit quicker, Intel i

Over 70,000 Memcached Servers Still Vulnerable to Remote Hacking

Over 70,000 Memcached Servers Still Vulnerable to Remote Hacking

Jul 18, 2017
Nothing in this world is fully secure, from our borders to cyberspace. I know vulnerabilities are bad, but the worst part comes in when people just don't care to apply patches on time. Late last year, Cisco's Talos intelligence and research group discovered three critical remote code execution (RCE) vulnerabilities in Memcached that exposed major websites including Facebook, Twitter, YouTube, Reddit, to hackers. Memcached is a popular open-source and easily deployable distributed caching system that allows objects to be stored in memory. The Memcached application has been designed to speed up dynamic web applications ( for example php-based websites) by reducing stress on the database that helps administrators to increase performance and scale web applications. It's been almost eight months since the Memcached developers have released patches for three critical RCE vulnerabilities (CVE-2016-8704, CVE-2016-8705 and CVE-2016-8706) but tens of thousands of servers

Cisco Finally Patches 0-Day Exploit Disclosed In Wikileaks-CIA Leak

May 10, 2017
Cisco Systems has finally released an update for its IOS and IOS XE software to address a critical vulnerability, disclosed nearly two months back in the CIA Vault 7 leak , that affects more than 300 of its switch models. The company identified the vulnerability in its product while analyzing "Vault 7" dump — thousands of documents and files leaked by Wikileaks, claiming to detail hacking tools and tactics of the U.S. Central Intelligence Agency (CIA). As previously reported , the vulnerability (CVE-2017-3881) resides in the Cluster Management Protocol (CMP) — which uses Telnet or SSH to deliver signals and commands on internal networks — in Cisco IOS and Cisco IOS XE Software. The vulnerability can be exploited remotely by sending "malformed CMP-specific Telnet options while establishing a Telnet session with an affected Cisco device configured to accept Telnet connections," researchers say. The company warned users on April 10 that an exploit targeting

Microsoft's own antivirus software made Windows 7, 8.1, RT and 10 computers, as well as Windows Server 2016 more vulnerable. Microsoft has just released an out-of-band security update to patch the crazy bad bug discovered by a pair of Google Project Zero researchers over the weekend. Security researchers Tavis Ormandy announced on Twitter during the weekend that he and another Project Zero researcher Natalie Silvanovich discovered "the worst Windows remote code [execution vulnerability] in recent memory." Natalie Silvanovich also published a  proof-of-concept (PoC) exploit code that fits in a single tweet. The reported RCE vulnerability , according to the duo, could work against default installations with "wormable" ability – capability to replicate itself on an infected computer and then spread to other PCs automatically. According to an advisory released by Microsoft, the remotely exploitable security flaw (CVE-2017-0290) exists in Microsoft
