As many as four zero-day security vulnerabilities have been disclosed in the HID Mercury access controller system that's used widely in healthcare, education, transportation, and government facilities. "The vulnerabilities uncovered allowed us to demonstrate the ability to remotely unlock and lock doors, subvert alarms and undermine logging and notification systems," Trellix security researchers Steve Povolny and Sam Quinn said in a report shared with The Hacker News. The issues, in a nutshell, could be weaponized by a malicious actor to gain full system control, including the ability to manipulate door locks. One of the bugs (CVE-2022-31481) includes an unauthenticated remote execution flaw that's rated 10 out of 10 for severity on the CVSS scoring system. HID Mercury controllers, which feature highly flexible configurations, are utilized by over 20 OEM (original equipment manufacturer) partners to design and deploy a broad range of access control systems, with

Networking hardware company Juniper Networks has released an "out-of-cycle" security update to address multiple flaws in the J-Web component of Junos OS that could be combined to achieve remote code execution on susceptible installations. The four vulnerabilities have a cumulative CVSS rating of 9.8, making them Critical in severity. They affect all versions of Junos OS on SRX and EX Series. "By chaining exploitation of these vulnerabilities, an unauthenticated, network-based attacker may be able to remotely execute code on the devices," the company  said  in an advisory released on August 17, 2023. The J-Web interface allows users to configure, manage, and monitor Junos OS devices. A brief description of the flaws is as follows - CVE-2023-36844  and  CVE-2023-36845  (CVSS scores: 5.3) - Two PHP external variable modification vulnerabilities in J-Web of Juniper Networks Junos OS on EX Series and SRX Series allows an unauthenticated, network-based attacker to

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

Google today released Chrome version 23 to the Stable Channel. 23.0.1271.64 for Windows, Mac, Linux, and Chrome Frame. Update includes patch for 12 vulnerabilities in the Windows version and two vulnerabilities in Mac OS X version. Chrome 23 is the support of the Do Not Track (DNT) protocol, number of new features including GPU accelerated video decoding on Windows and easier website permissions. " We recently enabled GPU-accelerated video decoding for Chrome on Windows. Dedicated graphics chips draw far less power than a computer's CPU, so using GPU-accelerated video decoding while watching videos can increase battery life significantly ." Out of  14 vulnerabilities , 6 vulnerabilities rated as high and rest are of either medium or low severity. CVE number of all bugs are - CVE-2012-5128, CVE-2012-5126, CVE-2012-5125, CVE-2012-5124, CVE-2012-5123, CVE-2012-5115, CVE-2012-5127, CVE-2012-5120, CVE-2012-5116, CVE-2012-5118, CVE-2012-5121, CVE-2012-5117,CVE-2012-5119, CVE-2

Google on Thursday patched six vulnerabilities in Chrome, and as usual, silently updated users' copies of the browser. The update to Chrome 10.0.648.204 also included two more blacklisted SSL certificates that may be related to last week's theft of nine digital certificates from a Comodo reseller. All six bugs were rated "high," Google's second-most-serious ranking in its threat scoring system. Of the half-dozen bugs, two were "use after free" flaws -- a type of memory management bug that can be exploited to inject attack code -- while a second pair were pegged by Google as "stale pointer" vulnerabilities, another kind of memory allocation flaw. As is Google's practice, the company locked down its bug-tracking database, blocking access to the technical details of the patched vulnerabilities. Google usually unlocks the bug entries several weeks, sometimes months later, to give users time to update before the information goes public. G

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  added  two years-old security flaws impacting TIBCO Software's JasperReports product to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The flaws, tracked as  CVE-2018-5430  (CVSS score: 7.7) and  CVE-2018-18809  (CVSS score: 9.9), were addressed by TIBCO in April 2018 and March 2019, respectively. TIBCO  JasperReports  is a Java-based reporting and data analytics platform for creating, distributing, and managing reports and dashboards. The first of the two issues, CVE-2018-5430, relates to an  information disclosure bug  in the server component that could enable an authenticated user to gain read-only access to arbitrary files, including key configurations. "The impact includes the possible read-only access by authenticated users to web application configuration files that contain the credentials used by the server," TIBCO noted at the time. "Tho

Microsoft discloses vulnerabilities in Chrome and Opera Microsoft has issued two advisories on Chrome and Opera, detailing remote code execution and information disclosure vulnerabilities. The disclosure is the result of the Microsoft Vulnerability Research (MSVR) system going live, which is one of the core items within their Coordinated Vulnerability Disclosure (CVD) program. On Tuesday, Microsoft issued an MSRV Advisory related to use-after-free memory errors in Google's Chrome, which, if exploited, would have triggered a crash and allowed remote code execution in the browsers sandbox. "When attempting to parse specially crafted Web content, Google Chrome references memory that has been freed. An attacker could exploit the vulnerability to cause the browser to become unresponsive and/or exit unexpectedly, allowing an attacker to run arbitrary code within the Google Chrome Sandbox," the advisory explains. Google has addressed the issue in a patch delivered last September. Vers

Three high-impact Unified Extensible Firmware Interface (UEFI) security vulnerabilities have been discovered impacting various Lenovo consumer laptop models, enabling malicious actors to deploy and execute firmware implants on the affected devices. Tracked as CVE-2021-3970, CVE-2021-3971, and CVE-2021-3972, the latter two "affect firmware drivers originally meant to be used only during the manufacturing process of Lenovo consumer notebooks," ESET researcher Martin Smolár  said  in a report published today. "Unfortunately, they were mistakenly included also in the production BIOS images without being properly deactivated," Smolár added. Successful exploitation of the flaws could permit an attacker to disable SPI flash protections or Secure Boot, effectively granting the adversary the ability to install persistent malware that can survive system reboots. CVE-2021-3970, on the other hand, relates to a case of memory corruption in the System Management Mode ( SMM

The U.S. Cybersecurity and Infrastructure Security Agency (CISA)  expanded  its Known Exploited Vulnerabilities Catalog to include a recently disclosed zero-day flaw in the Zimbra email platform citing evidence of active exploitation in the wild. Tracked as  CVE-2022-24682  (CVSS score: 6.1), the issue concerns a cross-site scripting (XSS) vulnerability in the Calendar feature in Zimbra Collaboration Suite that could be abused by an attacker to trick users into downloading arbitrary JavaScript code simply by clicking a link to exploit URLs in phishing messages. The Known Exploited Vulnerabilities Catalog is a  repository  of security flaws that have been seen abused by threat actors in attacks and that are required to be patched by Federal Civilian Executive Branch (FCEB) agencies. The vulnerability came to light on February 3, 2022, when cybersecurity firm Volexity  identified  a series of targeted spear-phishing campaigns aimed at European government and media entities that leve

Even after being aware of various active cyber attacks against the GPON Wi-Fi routers, if you haven't yet taken them off the Internet, then be careful—because a new botnet has joined the GPON party, which is exploiting an undisclosed zero-day vulnerability in the wild. Security researchers from Qihoo 360 Netlab have warned of at least one botnet operator exploiting a new zero-day vulnerability in the Gigabit-capable Passive Optical Network (GPON) routers, manufactured by South Korea-based DASAN Zhone Solutions. The botnet, dubbed TheMoon, which was first seen in 2014 and has added at least 6 IoT device exploits to its successor versions since 2017, now exploits a newly undisclosed zero-day flaw for Dasan GPON routers. Netlab researchers successfully tested the new attack payload on two different versions of GPON home router, though they didn't disclose details of the payload or release any further details of the new zero-day vulnerability to prevent more attacks. Th

Since the past few weeks, software giant Citrix has privately been rolling out a critical software update to its enterprise customers that patches multiple security vulnerabilities affecting Citrix ShareFile content collaboration platform. The security advisory—about which The Hacker News learned from Dimitri van de Giessen , an ethical hacker and system engineer—is scheduled to be available publicly later today on the Citrix website . Citrix ShareFile is an enterprise-level file sharing solution for businesses using which employees can securely exchange proprietary and sensitive business data with each other. The software offers an on-premises secure cloud environment for data storage with auditing capabilities and regulatory compliance controls. For example, a company can remotely lock or wipe data from potentially compromised mobile devices, or they're when lost or stolen. The newly identified security issues ( CTX-CVE-2020-7473 ) specifically affect customer-managed o

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday  added  two security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog due to active exploitation, while removing five bugs from the list due to lack of adequate evidence.

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

Consumer electronics maker Lenovo on Tuesday  rolled out fixes  to contain three security flaws in its UEFI firmware affecting over 70 product models. "The vulnerabilities can be exploited to achieve arbitrary code execution in the early phases of the platform boot, possibly allowing the attackers to hijack the OS execution flow and disable some important security features," Slovak cybersecurity firm ESET  said  in a series of tweets. Tracked as CVE-2022-1890, CVE-2022-1891, and CVE-2022-1892, all three bugs relate to  buffer overflow vulnerabilities  that have been described by Lenovo as leading to privilege escalation on affected systems. Martin Smolár from ESET has been credited with reporting the flaws. The bugs stem from an insufficient validation of an NVRAM variable called "DataSize" in three different drivers ReadyBootDxe, SystemLoadDefaultDxe, and SystemBootManagerDxe, resulting in a buffer overflow that could be weaponized to achieve code execution.

French security firm VUPEN Say New Bugs Can Bypass Google Chrome Sandbox ! Researchers at the French security firm VUPEN say that they have discovered several new vulnerabilities in Google Chrome that enable them to bypass the browser's sandbox, as well as ASLR and DEP and run arbitrary code on a vulnerable machine. The company said that they are not going to disclose the details of the bugs right now, but that they have shared information on them with some of their government customers through its customer program. The vulnerabilities are present in the latest version of Chrome running on Windows 7, VUPEN said. VUPEN published a video (  https://www.vupen.com/demos / ) that demonstrates an attack that exploits the Chrome vulnerabilities, although there is no further clues about the bugs themselves. "The exploit shown in this video is one of the most sophisticated codes we have seen and created so far as it bypasses all security features including ASLR/DEP/Sandbox, it

If you haven't recently updated your Drupal-based blog or business website to the latest available versions, it's the time. Drupal development team yesterday released important security updates for its widely used open-source content management software that addresses a critical and three "moderately critical" vulnerabilities in its core system. Considering that Drupal-powered websites are among the all-time favorite targets for hackers, the website administrators are highly recommended to install the latest release Drupal 7.69, 8.7.11, or 8.8.1 to prevent remote hackers from compromising web servers. Critical Symlinks Vulnerability in Drupal The only advisory with critical severity includes patches for multiple vulnerabilities in a third-party library, called ' Archive_Tar ,' that Drupal Core uses for creating, listing, extracting, and adding files to tar archives. The vulnerability resides in the way the affected library untar archives with sym

Well, that did not take long. Within just 10 days of the disclosure of two critical vulnerabilities in GPON router at least 5 botnet families have been found exploiting the flaws to build an army of million devices. Security researchers from Chinese-based cybersecurity firm Qihoo 360 Netlab have spotted 5 botnet families, including Mettle, Muhstik, Mirai, Hajime, and Satori, making use of the GPON exploit in the wild. As detailed in our previous post, Gigabit-capable Passive Optical Network (GPON) routers manufacturer by South Korea-based DASAN Zhone Solutions have been found vulnerable to an authentication bypass ( CVE-2018-10561 ) and a root-RCE ( CVE-2018-10562 ) flaws that eventually allow remote attackers to take full control of the device. Shortly after the details of the vulnerabilities went public, 360 Netlab researchers warned of threat actors exploiting both the flaws to hijack and add the vulnerable routers into their botnet malware networks. Now, the researche
