U.S. graphics chip specialist NVIDIA has released  software updates  to address a total of 26 vulnerabilities impacting its Jetson system-on-module (SOM) series that could be abused by adversaries to escalate privileges and even lead to denial-of-service and information disclosure. Tracked from CVE‑2021‑34372 through CVE‑2021‑34397, the flaws affect products Jetson TX1, TX2 series, TX2 NX, AGX Xavier series, Xavier NX, and Nano and Nano 2GB running all Jetson Linux versions prior to 32.5.1. The company credited Frédéric Perriot of Apple Media Products for reporting all the issues. The  NVIDIA Jetson  line consists of embedded Linux AI and computer vision compute modules and developer kits that primarily caters to AI-based computer vision applications and autonomous systems such as mobile robots and drones. Chief among the vulnerabilities is CVE‑2021‑34372 (CVSS score: 8.2), a buffer overflow flaw in its  Trusty  trusted execution environment (TEE) that could result in informatio

Google has rolled out yet another update to Chrome browser for Windows, Mac, and Linux to fix four security vulnerabilities, including one zero-day flaw that's being exploited in the wild. Tracked as  CVE-2021-30554 , the high severity flaw concerns a  use after free vulnerability  in WebGL (aka Web Graphics Library), a JavaScript API for rendering interactive 2D and 3D graphics within the browser. Successful exploitation of the flaw could mean corruption of valid data, leading to a crash, and even execution of unauthorized code or commands. The issue was reported to Google anonymously on June 15, Chrome technical program manager Srinivas Sista  noted , adding the company is "aware that an exploit for CVE-2021-30554 exists in the wild." While it's usually the norm to limit details of the vulnerability until a majority of users are updated with the fix, the development comes less than 10 days after Google addressed another zero-day vulnerability exploited in act

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica

Instagram has patched a new flaw that allowed anyone to view archived posts and stories posted by private accounts without having to follow them. "This bug could have allowed a malicious user to view targeted media on Instagram," security researcher Mayur Fartade  said  in a Medium post today. "An attacker could have been able to see details of private/archived posts, stories, reels, IGTV without following the user using Media ID." Fartade disclosed the issue to Facebook's security team on April 16, 2021, following which the shortcoming was patched on June 15. He was also awarded $30,000 as part of the company's bug bounty program. Although the attack requires knowing the media ID associated with an image, video, or album, by brute-forcing the identifiers, Fartade demonstrated that it was possible to craft a POST request to a GraphQL endpoint and retrieve sensitive data. As a consequence of the flaw, details such as like/comment/save count, display_

Cybersecurity researchers on Thursday disclosed as many as ten critical vulnerabilities impacting CODESYS automation software that could be exploited to achieve remote code execution on programmable logic controllers (PLCs). "To exploit the vulnerabilities, an attacker does not need a username or password; having network access to the industrial controller is enough," researchers from Positive Technologies  said . "The main cause of the vulnerabilities is insufficient verification of input data, which may itself be caused by failure to comply with the secure development recommendations." The Russian cybersecurity firm noted that it detected the vulnerabilities on a PLC offered by WAGO, which, among other automation technology companies such as Beckhoff, Kontron, Moeller, Festo, Mitsubishi, and HollySys, use CODESYS software for  programming and configuring  the controllers. CODESYS offers a development environment for programming controller applications for use

Major software vulnerabilities are a fact of life, as illustrated by the fact that Microsoft has patched between 55 and 110 vulnerabilities each month this year – with 7% to 17% of those vulnerabilities being critical. May had the fewest vulnerabilities, with a total of 55 and only four considered critical. The problem is that the critical vulnerabilities are things we have seen for many years, like remote code execution and privilege escalation. Microsoft isn't the only big name regularly patching major vulnerabilities: We see monthly security updates coming from Apple, Adobe, Google, Cisco, and others. Everything old is new again With major vulnerabilities in so many applications, is there any hope for a secure future? The answer is, of course, yes, but that does not mean there won't be challenges getting there. The vulnerabilities being seen may not be new to those of us who have been defending against attackers for years or even decades, but the adversaries continual

A new set of critical vulnerabilities has been disclosed in the Realtek RTL8170C Wi-Fi module that an adversary could abuse to gain elevated privileges on a device and hijack wireless communications. "Successful exploitation would lead to complete control of the Wi-Fi module and potential root access on the OS (such as Linux or Android) of the embedded device that uses this module," researchers from Israeli IoT security firm Vdoo  said  in a write-up published yesterday. The Realtek  RTL8710C  Wi-Fi SoC underpins Ameba, an Arduino-compatible programmable platform equipped with peripheral interfaces for building a variety of IoT applications by devices spanning across agriculture, automotive, energy, healthcare, industrial, security, and smart home sectors. The flaws affect all embedded and IoT devices that use the component to connect to Wi-Fi networks and would require an attacker to be on the same Wi-Fi network as the devices that use the RTL8710C module or know the ne

Fancy Product Designer, a WordPress plugin installed on over 17,000 sites, has been discovered to contain a critical file upload vulnerability that's being actively exploited in the wild to upload malware onto sites that have the plugin installed. Wordfence's threat intelligence team, which discovered the flaw, said it reported the issue to the plugin's developer on May 31. While the flaw has been acknowledged, it's yet to be addressed. Fancy Product Designer is a tool that enables businesses to offer customizable products, allowing customers to design any kind of item ranging from T-shirts to phone cases by offering the ability to upload images and PDF files that can be added to the products. "Unfortunately, while the plugin had some checks in place to prevent malicious files from being uploaded, these checks were insufficient and could easily be bypassed, allowing attackers to upload executable PHP files to any site with the plugin installed," Wordfence

Severe security flaws uncovered in popular Visual Studio Code extensions could enable attackers to compromise local machines as well as build and deployment systems through a developer's integrated development environment (IDE). The vulnerable extensions could be exploited to run arbitrary code on a developer's system remotely, in what could ultimately pave the way for supply chain attacks. Some of the extensions in question are "LaTeX Workshop," "Rainbow Fart," "Open in Default Browser," and "Instant Markdown," all of which have cumulatively racked up about two million installations between them. "Developer machines usually hold significant credentials, allowing them (directly or indirectly) to interact with many parts of the product," researchers from open-source security platform Snyk  said  in a deep-dive published on May 26. "Leaking a developer's private key can allow a malicious stakeholder to clone important

VMware has rolled out patches to address a critical security vulnerability in vCenter Server that could be leveraged by an adversary to execute arbitrary code on the server. Tracked as CVE-2021-21985 (CVSS score 9.8), the issue stems from a lack of input validation in the Virtual SAN ( vSAN ) Health Check plug-in, which is enabled by default in the vCenter Server. "A malicious actor with network access to port 443 may exploit this issue to execute commands with unrestricted privileges on the underlying operating system that hosts vCenter Server," VMware  said  in its advisory. VMware vCenter Server is a server management utility that's used to control virtual machines, ESXi hosts, and other dependent components from a single centralized location. The flaw affects vCenter Server versions 6.5, 6.7, and 7.0 and Cloud Foundation versions 3.x and 4.x. VMware credited Ricter Z of 360 Noah Lab for reporting the vulnerability. The patch release also rectifies an authenticati

Ivanti, the company behind Pulse Secure VPN appliances, has published a security advisory for a high severity vulnerability that may allow an authenticated remote attacker to execute arbitrary code with elevated privileges. "Buffer Overflow in Windows File Resource Profiles in 9.X allows a remote authenticated user with privileges to browse SMB shares to execute arbitrary code as the root user," the company  said  in an alert published on May 14. "As of version 9.1R3, this permission is not enabled by default." The flaw, identified as CVE-2021-22908, has a CVSS score of 8.5 out of a maximum of 10 and impacts Pulse Connect Secure versions 9.0Rx and 9.1Rx. In a report detailing the vulnerability, the CERT Coordination Center said the issue stems from the gateway's ability to connect to Windows file shares through a number of CGI endpoints that could be leveraged to carry out the attack. "When specifying a long server name for some SMB operations, the 

Cyber operatives affiliated with the Russian Foreign Intelligence Service (SVR) have switched up their tactics in response to previous public disclosures of their attack methods, according to a  new advisory  jointly published by intelligence agencies from the U.K. and U.S. Friday. "SVR cyber operators appear to have reacted [...] by changing their TTPs in an attempt to avoid further detection and remediation efforts by network defenders," the National Cyber Security Centre (NCSC)  said . These include the deployment of an open-source tool called  Sliver  to maintain their access to compromised victims as well as leveraging the ProxyLogon flaws in Microsoft Exchange servers to conduct post-exploitation activities. The development follows the  public attribution  of SVR-linked actors to the  SolarWinds  supply-chain attack last month. The adversary is also tracked under different monikers, such as Advanced Persistent Threat 29 (APT29), the Dukes, CozyBear, and Yttrium. T

When Spectre, a class of critical vulnerabilities impacting modern processors, was  publicly revealed  in January 2018, the researchers behind the discovery  said , "As it is not easy to fix, it will haunt us for quite some time," explaining the inspiration behind naming the speculative execution attacks. Indeed, it's been more than three years, and there is no end to Spectre in sight. A team of academics from the University of Virginia and University of California, San Diego, have discovered a  new line of attack  that bypasses all current Spectre protections built into the chips, potentially putting almost every system — desktops, laptops, cloud servers, and smartphones — once again at risk just as they were three years ago. The disclosure of  Spectre and Meltdown  opened a  floodgates  of sorts, what with  endless   variants  of the  attacks  coming to light in the intervening years, even as chipmakers like Intel, ARM, and AMD have continually scrambled to incorpo

Apple on Monday released security updates for  iOS ,  macOS , and  watchOS  to address three zero-day flaws and expand patches for a fourth vulnerability that the company said might have been exploited in the wild. The weaknesses all concern WebKit, the browser engine which powers Safari and other third-party web browsers in iOS, allowing an adversary to execute arbitrary code on target devices. A summary of the three security bugs are as follows - CVE-2021-30663:  An integer overflow vulnerability that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addressed with improved input validation. CVE-2021-30665:  A memory corruption issue that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addressed with improved state management. CVE-2021-30666:  A buffer overflow vulnerability that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addr

Cybersecurity researchers on Wednesday disclosed a new bypass vulnerability (CVE-2021-23008) in the Kerberos Key Distribution Center (KDC) security feature impacting F5 Big-IP application delivery services. "The KDC Spoofing vulnerability allows an attacker to bypass the Kerberos authentication to Big-IP Access Policy Manager (APM), bypass security policies and gain unfettered access to sensitive workloads," Silverfort researchers Yaron Kassner and Rotem Zach said in a report. "In some cases this can be used to bypass authentication to the Big-IP admin console as well." Coinciding with the public disclosure, F5 Networks has released patches to address the weakness (CVE-2021-23008, CVSS score 8.1), with fixes introduced in BIG-IP APM versions 12.1.6, 13.1.4, 14.1.4, and 15.1.3. A similar patch for version 16.x is expected at a future date. "We recommend customers running 16.x check the security advisory to assess their exposure and get details on mitigati

Google on Tuesday released an update for Chrome web browser for Windows, Mac, and Linux, with a total of seven security fixes, including one flaw for which it says an exploit exists in the wild. Tracked as CVE-2021-21224 , the flaw concerns a type confusion vulnerability in V8 open-source JavaScript engine that was reported to the company by security researcher Jose Martinez on April 5 According to security researcher  Lei Cao , the bug [ 1195777 ] is triggered when performing integer data type conversion, resulting in an out-of-bounds condition that could be used to achieve arbitrary memory read/write primitive. "Google is aware of reports that exploits for CVE-2021-21224 exist in the wild," Chrome's Technical Program Manager Srinivas Sista  said  in a blog post. The update comes after proof-of-concept (PoC) code exploiting the flaw published by a researcher named " frust " emerged on April 14 by taking advantage of the fact that the issue was addressed

SonicWall has addressed three critical security vulnerabilities in its hosted and on-premises email security (ES) product that are being actively exploited in the wild. Tracked as CVE-2021-20021 and CVE-2021-20022, the  flaws  were discovered and reported to the company by FireEye's Mandiant subsidiary on March 26, 2021, after the cybersecurity firm detected post-exploitation web shell activity on an internet-accessible system within a customer's environment that had SonicWall's ES application running on a Windows Server 2012 installation. A third flaw (CVE-2021-20023) identified by FireEye was disclosed to SonicWall on April 6, 2021. FireEye is tracking the malicious activity under the moniker UNC2682. "These vulnerabilities were executed in conjunction to obtain administrative access and code execution on a SonicWall ES device," researchers Josh Fleischer, Chris DiGiamo, and Alex Pennino  said . The adversary leveraged these vulnerabilities, with intimate

In its April slate of patches, Microsoft rolled out fixes for a total of  114 security flaws , including an actively exploited zero-day and four remote code execution bugs in Exchange Server. Of the  114 flaws , 19 are rated as Critical, 88 are rated Important, and one is rated Moderate in severity. Chief among them is  CVE-2021-28310 , a privilege escalation vulnerability in Win32k that's said to be under active exploitation, allowing attackers to elevate privileges by running malicious code on a target system.  Cybersecurity firm Kaspersky, which discovered and reported the flaw to Microsoft in February, linked the zero-day exploit to a threat actor named Bitter APT, which was found exploiting a similar flaw ( CVE-2021-1732 ) in attacks late last year. "It is an escalation of privilege (EoP) exploit that is likely used together with other browser exploits to escape sandboxes or get system privileges for further access," Kaspersky researcher Boris Larin  said . NS

Cybersecurity researchers on Monday disclosed two new vulnerabilities in Linux-based operating systems that, if successfully exploited, could let attackers circumvent mitigations for speculative attacks such as  Spectre  and obtain sensitive information from kernel memory. Discovered by  Piotr Krysiuk  of Symantec's Threat Hunter team, the flaws — tracked as CVE-2020-27170 and CVE-2020-27171 (CVSS scores: 5.5) — impact all Linux kernels prior to 5.11.8. Patches for the security issues were released on March 20, with Ubuntu, Debian, and Red Hat deploying fixes for the vulnerabilities in their respective Linux distributions. While  CVE-2020-27170  can be abused to reveal content from any location within the kernel memory,  CVE-2020-27171 can be used to retrieve data from a 4GB range of kernel memory. First documented in January 2018,  Spectre and Meltdown  take advantage of flaws in modern processors to  leak data  that are currently processed on the computer, thereby allowing

The maintainers of OpenSSL have released a fix for two high-severity security flaws in its software that could be exploited to carry out denial-of-service (DoS) attacks and bypass certificate verification. Tracked as CVE-2021-3449 and CVE-2021-3450 , both the  vulnerabilities  have been resolved in an update (version OpenSSL 1.1.1k) released on Thursday. While CVE-2021-3449 affects all OpenSSL 1.1.1 versions, CVE-2021-3450 impacts OpenSSL versions 1.1.1h and newer. OpenSSL is a software library consisting of cryptographic functions that implement the Transport Layer Security protocol with the goal of securing communications sent over a computer network. According to an advisory published by OpenSSL, CVE-2021-3449 concerns a potential DoS vulnerability arising due to NULL pointer dereferencing that can cause an OpenSSL TLS server to crash if in the course of renegotiation the client transmits a malicious "ClientHello" message during the  handshake  between the server and
