"On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed." Multiple security researchers associated with the Ant Group Light-Year Security Lab and QiAnXin have been credited with independently discovering and reporting CVE-2024-22252. Secur...

WordPress has released version 6.4.2 with a patch for a critical security flaw that could be exploited by threat actors by combining it with another bug to execute arbitrary PHP code on vulnerable sites. "A remote code execution vulnerability that is not directly exploitable in core; however, the security team feels that there is a potential for high severity when combined with some plugins, especially in multisite installations," WordPress  said . According to WordPress security company Wordfence, the  issue  is rooted in the WP_HTML_Token class that was introduced in version 6.4 to improve HTML parsing in the block editor. A threat actor with the ability to exploit a PHP object injection vulnerability present in any other plugin or theme to chain the two issues to execute arbitrary code and seize control of the targeted site. "If a  POP [property-oriented programming] chain  is present via an additional plugin or theme installed on the target system, it ...

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...

Merely weeks after releasing out-of-band patches for iOS, iPadOS, macOS and watchOS, Apple has issued yet another security update for iPhone, iPad, and Apple Watch to fix a critical zero-day weakness that it says is being actively exploited in the wild. Tracked as CVE-2021-1879 , the vulnerability relates to a WebKit flaw that could enable adversaries to process maliciously crafted web content that may result in universal cross-site scripting attacks. "This issue was addressed by improved management of object lifetimes," the iPhone maker noted. Apple has credited Clement Lecigne and Billy Leonard of Google's Threat Analysis Group for discovering and reporting the issue. While details of the flaw have not been disclosed, the company said it's aware of reports that CVE-2021-1879 may have been actively exploited. Updates are available for the following devices: iOS 12.5.2  - Phone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6t...

Adobe today released out-of-band software updates for After Effects and Media Encoder applications that patch a total of two new critical vulnerabilities. Both critical vulnerabilities exist due to out-of-bounds write memory corruption issues and can be exploited to execute arbitrary code on targeted systems by tricking victims into opening a specially crafted file using the affected software. The bug ( CVE-2020-3765 ) in Adobe After Effects, an application for creating motion graphics and special effects used in the video, was discovered by security researcher Matt Powell and reported to Adobe via Trend Micro Zero Day Initiative project. Whereas, the second issue ( CVE-2020-3764 ) affecting Adobe Media Encoder, software for encoding and compressing audio or video files, was discovered by Canadian security researcher Francis Provencher. None of the security vulnerabilities fixed in this batch of Adobe updates were publicly disclosed or found being exploited in the wild, as th...

Microsoft today released its monthly batch of software security updates for the July month to patch a total of 77 vulnerabilities, 14 are rated Critical, 62 are Important, and 1 is rated Moderate in severity. The July 2019 security updates include patches for various supported versions of Windows operating systems and other Microsoft products, including Internet Explorer, Edge, Office, Azure DevOps, Open Source Software, .NET Framework, Azure, SQL Server, ASP.NET, Visual Studio, and Exchange Server. Details of 6 security vulnerabilities, all rated important, were made public before a patch was released, none of which were found being exploited in the wild. However, two new privilege escalation vulnerabilities, one affects all supported versions of the Windows operating system, and the other affects Windows 7 and Server 2008, have been reported as being actively exploited in the wild. Both actively exploited vulnerabilities lead to elevation of privilege, one (CVE-2019-1132)...

I hope you had biggest, happiest and craziest New Year celebration, but now it's time to come back at work and immediately update your systems to patch new security flaws that could exploit your computer just by opening a PDF file. Adobe has issued an out-of-band security update to patch two critical vulnerabilities in the company's Acrobat and Reader for both the Windows and macOS operating systems. Though the San Jose, California-based software company did not give details about the vulnerabilities, it did classify the security flaws as critical since they allow privilege escalation and arbitrary code execution in the context of the current user. Both the vulnerabilities were reported to Adobe by security researchers--Abdul-Aziz Hariri and Sebastian Apelt—from Trend Micro's Zero Day Initiative (ZDI). Critical Adobe Acrobat and Reader Vulnerabilities The first vulnerability, reported by Apelt and identified as CVE-2018-16011, is a use-after-free bug that can lead...

Adobe is closing out this year with its December Patch Tuesday update to address a massive number of security vulnerabilities for just its two PDF apps—more than double the number of what Microsoft patched this month for its several products. Adobe today released patches for 87 vulnerabilities affecting its Acrobat and Reader software products for both macOS and Windows operating systems, of which 39 are rated as critical and 48 important in severity. The security update comes less than a week after Adobe released patches for a critical zero-day vulnerability (CVE-2018-15982) in Flash Player that was actively being exploited in a targeted attack targeting a Russian state health care institution. The critical vulnerabilities addressed today in Acrobat and Reader include three heap-overflow bugs, five out-of-bounds write flaws, two untrusted pointer dereference issues, two buffer errors, and 24 use-after-free bugs. Upon successful exploitation, all of the above critical vulner...

Microsoft today, on its year-end December Patch Tuesday, released security updates to patch a total 39 vulnerabilities its Windows operating systems and applications—10 of which are rated as critical and other important in severity. One of the security vulnerabilities patched by the tech giant this month is listed as publicly known at the time of release, and one is a zero-day reported as being actively exploited in the wild by multiple hacking groups, including FruityArmor and SandCat APTs. Discovered and reported by security researchers at Kaspersky, the zero-day attack exploits an elevation-of-privilege (EoP) bug in the Windows Kernel (ntoskrnl.exe) that could allow malicious programs to execute arbitrary code with higher privileges on the targeted systems. The vulnerability, tracked as CVE-2018-8611  and classified important in severity, resides in the Kernel Transaction Manager, which occurs due to improper processing of transacted file operations in kernel mode. The f...

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...

" Always keep your operating system and software up-to-date ." This is one of the most popular and critical advice that every security expert strongly suggests you to follow to prevent yourself from major cyber attacks. However, even if you attempt to install every damn software update that lands to your system, there is a good chance of your computer remaining outdated and vulnerable. Researchers from security firm Duo Labs analysed over 73,000 Macs systems and discovered that a surprising number of Apple Mac computers either fails to install patches for EFI firmware vulnerabilities or doesn't receive any update at all. Apple uses Intel-designed Extensible Firmware Interface (EFI) for Mac computers that work at a lower level than a computer's OS and hypervisors—and controls the boot process. EFI runs before macOS boots up and has higher-level privileges that, if exploited by attackers, could allow EFI malware to control everything without being detecte...

The massive Equifax data breach that exposed highly sensitive data of as many as 143 million people was caused by exploiting a flaw in Apache Struts framework, which Apache patched over two months earlier of the security incident, Equifax has confirmed. Credit rating agency Equifax is yet another example of the companies that became victims of massive cyber attacks due to not patching a critical vulnerability on time, for which patches were already issued by the respected companies. Rated critical with a maximum 10.0 score, the Apache Struts2 vulnerability (CVE-2017-5638) exploited in the Equifax breach was disclosed and fixed by Apache on March 6 with the release of Apache Struts version 2.3.32 or 2.5.10.1. This flaw is separate from CVE-2017-9805, another Apache Struts2 vulnerability that was patched earlier this month, which was a programming bug that manifests due to the way Struts REST plugin handles XML payloads while deserializing them, and was fixed in Struts ve...

Adobe may kill Flash Player by the end of 2020, but until then, the company would not stop providing security updates to the buggy software . As part of its monthly security updates, Adobe has released patches for eight security vulnerabilities in its three products, including two vulnerabilities in Flash Player, four in ColdFusion, and two in RoboHelp—five of these are rated as critical. Both of the Adobe Flash Player vulnerabilities can be exploited for remote code execution on the affected device, and both have been classified as critical. None of the patched vulnerabilities has reportedly been exploited in the wild, according to the company. The critical Flash Player flaws are tracked as CVE-2017-11281 and CVE-2017-11282 and were discovered by Mateusz Jurczyk and Natalie Silvanovich of Google Project Zero, respectively. Both the security vulnerabilities are memory corruption issues that could lead to remote code execution and affect all major operating system, includi...

The U.S. Federal Trade Commission has announced a "prize competition" for creating a software or hardware-based solution with the ability to auto-patch vulnerable Internet of Things (IoT) devices. Today we are surrounded by a number of Internet-connected devices. Our homes are filled with tiny computers embedded in everything from security cameras, TVs and refrigerators to thermostat and door locks. While IoT is going to improve life for many, the number of security risks due to lack of stringent security measures and encryption mechanisms in the devices have increased exponentially, giving attackers a large number of entry points to affect you in some or the other way. Remember Mirai Botnet ? A botnet of just 100,000 hijacked IoT devices was used to flood the Dyn DNS service with unwanted requests and close down the Internet for Millions of Users a few months ago. At that time, Chinese firm Hangzhou Xiongmai Technology admitted its smart products – DVRs and ...

In Brief Microsoft's August Patch Tuesday offers nine security bulletins with five rated critical, resolving 34 security vulnerabilities in Internet Explorer (IE), Edge, and Office, as well as some serious high-profile security issues with Windows. A security bulletin, MS16-102 , patches a single vulnerability (CVE-2016-3319) that could allow an attacker to control your computer just by getting you to view specially-crafted PDF content in your web browser. Users of Microsoft Edge on Windows 10 systems are at a significant risk for remote code execution (RCE) attacks through a malicious PDF file. Web Page with PDF Can Hack Your Windows Computer Since Edge automatically renders PDF content when the browser is set as a default browser, this vulnerability only affects Windows 10 users with Microsoft Edge set as the default browser, as the exploit would execute by simply by viewing a PDF online. Web browsers for all other affected operating systems do not automatically ...

Microsoft has released 16 security bulletins on Tuesday resolving a total of 44 security holes in its software, including Windows, Office, Exchange Server, Internet Explorer and Edge. Five bulletins have been rated "critical" that could be used to carry out remote code execution and affected: Windows, Internet Explorer (IE), Edge (the new, improved IE), Microsoft Office and Office services; and the remaining 11 are marked important. One of the critical issues, MS16-071 that caused alarm bells to go off for many security experts involves a Use-After-Free bug (CVE-2016-3227), which affects Microsoft Windows Domain Name System (DNS) servers for Windows Server 2012 and 2012 R2. The vulnerability resides in the way servers handle requests. Attackers could send a specially crafted request to a DNS server and convinced it to run arbitrary code in the context of the Local System Account, Microsoft's advisory warns. Another critical vulnerability is addressed in MS16-070, which patc...

In Brief The Smartphone users are fed up with slow security updates, so two United States federal agencies have launched an official inquiry to know how manufacturers and carriers deal with mobile phone security updates and what they are doing to roll out patches as quickly as possible. The Smartphone patch update mechanism is broken, and someone has to fix it. Most smartphone models are not receiving available security patches, and the risk of vulnerabilities , malware infections , and data loss are leaving consumers vulnerable to attacks and putting businesses and corporate networks at risk. The United States federal regulators want to know how and when mobile phone manufacturers and cell phone carriers release security updates to assure its users' security, amid mounting concerns over security vulnerabilities. The Federal Communications Commission (FCC) in partnership with the Federal Trade Commission (FTC) have launched its own, parallel inquiry into mobile devic...

In Brief The Microsoft's Windows Defender Advanced Threat Hunting team detected that a cyber espionage group of hackers, known as PLATINUM, has found a way to turn the Windows's Hotpatching technique (a way of updating the operating system without requiring a restart) to hide its malware from Antivirus products. PLATINUM group has been active since 2009 and launching large-scale attacks against governmental organizations, intelligence agencies, defense institutes and telecommunication providers in South and Southeast Asia. Practically speaking, the most important thing for a sophisticated APT hacker and a cyber-espionage group is to remain undetected for the longest possible period. Well, that's exactly what an APT (Advanced Persistent Threat) group has achieved. The Microsoft's Windows Defender Advanced Threat Hunting team has discovered that an APT group, dubbed Platinum, has been spying on high-profile targets by abusing a " novel " technique called...
