A new security flaw has been disclosed in the libcue library impacting GNOME Linux systems that could be exploited to achieve remote code execution (RCE) on affected hosts. Tracked as  CVE-2023-43641  (CVSS score: 8.8), the  issue  is described as a case of memory corruption in libcue, a library designed for parsing  cue sheet files . It impacts versions 2.2.1 and prior. libcue is incorporated into Tracker Miners , a search engine tool that's included by default in GNOME and indexes files in the system for easy access. The problem is rooted in an out-of-bounds array access in the track_set_index function that allows for achieving code execution on the machine simply by tricking a victim into clicking a malicious link and downloading a .cue file. "A user of the GNOME desktop environment can be exploited by downloading a cue sheet from a malicious webpage," according to a  description  of the vulnerability in the National Vulnerability Database (NVD). "Because t

Just after a new security vulnerability surfaced Wednesday, many tech outlets started comparing it with HeartBleed, the serious security glitch uncovered last year that rendered communications with many well-known web services insecure, potentially exposing Millions of plain-text passwords. But don't panic. Though the recent vulnerability has a more terrific name than HeartBleed , it is not going to cause as much danger as HeartBleed did. Dubbed VENOM , stands for Virtualized Environment Neglected Operations Manipulation , is a virtual machine security flaw uncovered by security firm CrowdStrike that could expose most of the data centers to malware attacks, but in theory. Yes, the risk of Venom vulnerability is theoretical as there is no real-time exploitation seen yet, while, on the other hand, last year's HeartBleed bug was practically exploited by hackers unknown number of times, leading to the theft of critical personal information. Now let's know more about Ven

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,

Apple recently fixed a security vulnerability in the macOS operating system that could be potentially exploited by a threat actor to "trivially and reliably" bypass a "myriad of foundational macOS security mechanisms" and run arbitrary code. Security researcher Patrick Wardle  detailed  the discovery in a series of tweets on Thursday. Tracked as CVE-2021-30853 (CVSS score: 5.5), the issue relates to a scenario where a rogue macOS app may circumvent  Gatekeeper  checks, which ensure that only trusted apps can be run and that they have passed an automated process called " app notarization ." The iPhone maker, crediting Gordon Long of Box with reporting the flaw, said it  addressed the weakness  with improved checks as part of macOS 11.6 updates officially released on September 20, 2021. "Such bugs are often particularly impactful to everyday macOS users as they provide a means for adware and malware authors to sidestep macOS security mechanisms, …m

Update (22 June 2019)  — More technical details and proof-of-concept for the OutLook for Android vulnerability has been released that we have covered in a separate article here. Microsoft today released an updated version of its "Outlook for Android" that patches an important security vulnerability in the popular email app that is currently being used over 100 million users. According to an advisory , Outlook app with versions before 3.0.88 for Android contains a stored cross-site scripting vulnerability ( CVE-2019-1105 ) in the way the app parses incoming email messages. If exploited, remote attackers can execute malicious in-app client-side code on the targeted devices just by sending them emails with a specially crafted message. "The attacker who successfully exploited this vulnerability could then perform cross-site scripting attacks on the affected systems and run scripts in the security context of the current user." According to Microsoft, the fl

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  added  three flaws to the Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation.

According to Trend Micro's Zero Day Initiative, the flaw has been  put to use  by threat actors associated with the Mirai botnet since April 11, 2023. The second flaw to be added to the KEV catalog is CVE-2021-45046, a remote code execution affecting the Apache Log4j2 logging library that  came to light  in December 2021. It's cu

VMware has rolled out security updates to resolve a critical flaw affecting Carbon Black App Control that could be exploited to bypass authentication and take control of vulnerable systems. The vulnerability, identified as CVE-2021-21998, is rated 9.4 out of 10 in severity by the industry-standard Common Vulnerability Scoring System (CVSS) and affects App Control (AppC) versions 8.0.x, 8.1.x, 8.5.x, and 8.6.x. Carbon Black App Control  is a security solution designed to lock down critical systems and servers to prevent unauthorized changes in the face of cyber-attacks and ensure compliance with regulatory mandates such as PCI-DSS, HIPAA, GDPR, SOX, FISMA, and NERC. "A malicious actor with network access to the VMware Carbon Black App Control management server might be able to obtain administrative access to the product without the need to authenticate," the California-based cloud computing and virtualization technology company  said  in an advisory. CVE-2021-21998 is th

Romanian cybersecurity technology company Bitdefender on Monday revealed that attempts are being made to target Windows machines with a novel ransomware family called  Khonsari  as well as a remote access Trojan named  Orcus  by exploiting the recently disclosed critical Log4j vulnerability . The attack leverages the remote code execution (RCE) flaw to download an additional payload, a .NET binary, from a remote server that encrypts all the files with the extension ".khonsari" and displays a ransom note that urges the victims to make a Bitcoin payment in exchange for recovering access to the files. Tracked as CVE-2021-44228 , the RCE vulnerability is also known by the monikers "Log4Shell" or "Logjam" and impacts versions 2.0-beta9 to 2.14.1 of the software library. In simple terms, the bug could force an affected system to download malicious software, giving the attackers a digital beachhead on servers located within corporate networks. Log4j is an op

APIs, more formally known as application programming interfaces, empower apps and microservices to communicate and share data. However, this level of connectivity doesn't come without major risks. Hackers can exploit vulnerabilities in APIs to gain unauthorized access to sensitive data or even take control of the entire system. Therefore, it's essential to have a robust API security posture to protect your organization from potential threats. What is API posture management? API posture management refers to the process of monitoring and managing the security posture of your APIs. It involves identifying potential vulnerabilities and misconfigurations that could be exploited by attackers, and taking the necessary steps to remediate them. Posture management also helps organizations classify sensitive data and ensure that it's compliant with the leading data compliance regulations such as GDPR, HIPAA, and PCI DSS.  As mentioned above, APIs are a popular target for attackers

Did you know… last month's widespread WannaCry ransomware attack forced Microsoft to release security updates against EternalBlue SMB exploit for unsupported versions of Windows, but the company left other three Windows zero-day exploits unpatched? For those unaware, EternalBlue is a Windows SMB flaw that was leaked by the Shadow Brokers in April and then abused by the WannaCry ransomware to infect nearly 300,000 computers in more than 150 countries within just 72 hours on 12th of May. Shortly after WannaCry outbreak, we reported that three unpatched Windows exploits , codenamed " EsteemAudit, " " ExplodingCan ," and " EnglishmanDentist ," were also being exploited by individuals and state-sponsored hackers in the wild. Specially EsteemAudit , one of the dangerous Windows hacking tool that targets remote desktop protocol (RDP) service on Microsoft Windows Server 2003 and Windows XP machines, while ExplodingCan exploits bugs in IIS 6.0 and E

Cisco and VMware have released security updates to address critical security flaws in their products that could be exploited by malicious actors to execute arbitrary code on affected systems. The most severe of the vulnerabilities is a command injection flaw  in Cisco Industrial Network Director  (CVE-2023-20036, CVSS score: 9.9), which resides in the web UI component and arises as a result of improper input validation when  uploading a Device Pack . "A successful exploit could allow the attacker to execute arbitrary commands as NT AUTHORITY\SYSTEM on the underlying operating system of an affected device," Cisco  said  in an advisory released on April 19, 2023. The networking equipment major also resolved a medium-severity file permissions vulnerability in the same product (CVE-2023-20039, CVSS score: 5.5) that an authenticated, local attacker could abuse to view sensitive information. Patches have been made available in  version 1.11.3 , with Cisco crediting an unnamed

New research has disclosed what's being called a security vulnerability in Microsoft 365 that could be exploited to infer message contents due to the use of a broken cryptographic algorithm. "The [Office 365 Message Encryption] messages are encrypted in insecure Electronic Codebook ( ECB ) mode of operation," Finnish cybersecurity company WithSecure  said  in a report published last week. Office 365 Message Encryption (OME) is a security mechanism used to send and receive encrypted email messages between users inside and outside an organization without revealing anything about the communications themselves. A consequence of the newly disclosed issue is that rogue third-parties gaining access to the encrypted email messages may be able to decipher the messages, effectively breaking confidentiality protections. Electronic Codebook is one of the simplest modes of encryption wherein each message block is encoded separately by a key, meaning identical plaintext blocks wi

You must update your Google Chrome immediately to the latest version of the web browsing application. Security researcher Clement Lecigne of Google's Threat Analysis Group discovered and reported a high severity vulnerability in Chrome late last month that could allow remote attackers to execute arbitrary code and take full control of the computers. The vulnerability, assigned as CVE-2019-5786 , affects the web browsing software for all major operating systems including Microsoft Windows, Apple macOS, and Linux. Without revealing technical details of the vulnerability, the Chrome security team only says the issue is a use-after-free vulnerability in the FileReader component of the Chrome browser, which leads to remote code execution attacks. What's more worrisome? Google warned that this zero-day RCE vulnerability is actively being exploited in the wild by attackers to target Chrome users. "Access to bug details and links may be kept restricted until a majo

Details have emerged about a new unpatched security vulnerability in Fortinet's web application firewall (WAF) appliances that could be abused by a remote, authenticated attacker to execute malicious commands on the system. "An OS command injection vulnerability in FortiWeb's management interface (version 6.3.11 and prior) can allow a remote, authenticated attacker to execute arbitrary commands on the system, via the SAML server configuration page," cybersecurity firm Rapid7  said  in an advisory published Tuesday. "This vulnerability appears to be related to  CVE-2021-22123 , which was addressed in  FG-IR-20-120 ." Rapid7 said it discovered and reported the issue in June 2021. Fortinet is expected to release a patch at the end of August with version Fortiweb 6.4.1. The command injection flaw is yet to be assigned a CVE identifier, but it has a severity rating of 8.7 on the CVSS scoring system. Successful exploitation of the vulnerability can allow auth

Microsoft last week rolled out updates for the Edge browser with  fixes for two security issues , one of which concerns a security bypass vulnerability that could be exploited to inject and execute arbitrary code in the context of any website. Tracked as  CVE-2021-34506  (CVSS score: 5.4), the weakness stems from a universal cross-site scripting (UXSS) issue that's triggered when automatically translating web pages using the browser's  built-in feature via Microsoft Translator . Credited for discovering and reporting CVE-2021-34506 are Ignacio Laurence as well as Vansh Devgan and Shivam Kumar Singh with CyberXplore Private Limited.  "Unlike the common XSS attacks, UXSS is a type of attack that exploits client-side vulnerabilities in the browser or browser extensions in order to generate an XSS condition, and execute malicious code," CyberXplore researchers  said  in a write-up shared with The Hacker News. "When such vulnerabilities are found and exploited,

A popular gaming platform used by hundreds of millions of people worldwide has been found vulnerable to multiple security flaws that could have allowed remote hackers to takeover players' accounts and steal sensitive data. The vulnerabilities in question reside in the "Origin" digital distribution platform developed by Electronic Arts (EA)—the world's second-largest gaming company with over 300 million users—that allows users to purchase and play some of the most popular video games including Battlefield, Apex Legends, Madden NFL, and FIFA. The Origin platform also manages users EA Games account authentication and allows them to find friends, join games, and manage their profiles. Discovered by researchers at Check Point and CyberInt, the vulnerabilities when chained together could have allowed attackers to hijack gamer's EA account just by convincing them into opening an official webpage from the EA Games website. To perform this attack, as shown in th

Cybersecurity researchers on Thursday revealed security issues in the Android app developed by Chinese drone-maker Da Jiang Innovations (DJI) that comes with an auto-update mechanism that bypasses Google Play Store and could be used to install malicious applications and transmit sensitive personal information to DJI's servers. The twin reports, courtesy of cybersecurity firms Synacktiv and GRIMM , found that DJI's Go 4 Android app not only asks for extensive permissions and collects personal data (IMSI, IMEI, the serial number of the SIM card), it makes use of anti-debug and encryption techniques to thwart security analysis. "This mechanism is very similar to command and control servers encountered with malware," Synacktiv said. "Given the wide permissions required by DJI GO 4 — contacts, microphone, camera, location, storage, change network connectivity — the DJI or Weibo Chinese servers have almost full control over the user's phone." The

Cybersecurity researchers have identified a new attack that exploits misconfigurations in Apache Hadoop and Flink to deploy cryptocurrency miners within targeted environments. "This attack is particularly intriguing due to the attacker's use of packers and rootkits to conceal the malware," Aqua security researchers Nitzan Yaakov and Assaf Morag  said  in an analysis published earlier this week. "The malware deletes contents of specific directories and modifies system configurations to evade detection." The infection chain targeting Hadoop leverages a misconfiguration in the YARN's (Yet Another Resource Negotiator)  ResourceManager , which is responsible for tracking resources in a cluster and scheduling applications. Specifically, the misconfiguration can be exploited by an unauthenticated, remote threat actor to execute arbitrary code by means of a crafted HTTP request, subject to the privileges of the user on the node where the code is executed. The

Two days ago, The Hacker News (THN) reported about the Zero-day vulnerability in the freshly patched Adobe Flash Player . The vulnerability was exploited in the wild by a well-known group of Russian hackers, named " Pawn Storm ," to target several foreign affairs ministries worldwide. The zero-day flaw allowed hackers to have complete control of the users' machine, potentially putting all the Flash Player users at a potentially high risk. Since then, there was no patch available to make flawed utility safe. However, Adobe has now patched the zero-day vulnerability, along with some critical vulnerabilities whose details are yet to be disclosed. Yesterday, the company published a post on their official security bulletin ( APSB15-27 ) detailing the risks associated with the zero-day and how a user can get rid of them. The critical vulnerabilities are assigned following CVE numbers: CVE-2015-7645 CVE-2015-7647 CVE-2015-7648 Also, Adobe is kn
