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

Two separate teams of security researchers have published working proof-of-concept exploits for an unpatchable vulnerability in Nvidia's Tegra line of embedded processors that comes on all currently available Nintendo Switch consoles. Dubbed Fusée Gelée and ShofEL2 , the exploits lead to a coldboot execution hack that can be leveraged by device owners to install Linux, run unofficial games, custom firmware, and other unsigned code on Nintendo Switch consoles, which is typically not possible. Both exploits take advantage of a buffer overflow vulnerability in the USB software stack of read-only boot instruction ROM (IROM/bootROM), allowing unauthenticated arbitrary code execution on the game console before any lock-out operations (that protect the chip's bootROM) take effect. The buffer overflow vulnerability occurs when a device owner sends an "excessive length" argument to an incorrectly coded USB control procedure, which overflows a crucial direct memory a

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,

Not just Facebook , a new vulnerability discovered in Linkedin's popular AutoFill functionality found leaking its users' sensitive information to third party websites without the user even knowing about it. LinkedIn provides an AutoFill plugin for a long time that other websites can use to let LinkedIn users quickly fill in profile data, including their full name, phone number, email address, ZIP code, company and job title, with a single click. In general, the AutoFill button only works on specifically "whitelisted websites," but 18-year-old security researcher Jack Cable of Lightning Security said it is not just the case. Cable discovered that the feature was plagued with a simple yet important security vulnerability that potentially enabled any website (scrapers) secretly harvest user profile data and the user would not even realize of the event. A legitimate website would likely place a AutoFill button near the fields the button can fill, but accordin

If you have installed a network-attached storage device manufactured by LG Electronics, you should take it down immediately, read this article carefully and then take appropriate action to protect your sensitive data. A security researcher has revealed complete technical details of an unpatched critical remote command execution vulnerability in various LG NAS device models that could let attackers compromise vulnerable devices and steal data stored on them. LG's Network Attached Storage (NAS) device is a dedicated file storage unit connected to a network that allows users to store and share data with multiple computers. Authorized users can also access their data remotely over the Internet. The vulnerability has been discovered by the researcher at privacy advocate firm VPN Mentor, the same company that last month revealed severe flaws in three popular VPNs —HotSpot Shield, PureVPN, and ZenMate VPN. The LG NAS flaw is a pre-authenticated remote command injection vulnera

A security researcher has disclosed details of an important vulnerability in Microsoft Outlook for which the company released an incomplete patch this month —almost 18 months after receiving the responsible disclosure report. The Microsoft Outlook vulnerability (CVE-2018-0950) could allow attackers to steal sensitive information, including users' Windows login credentials, just by convincing victims to preview an email with Microsoft Outlook, without requiring any additional user interaction. The vulnerability, discovered by Will Dormann of the CERT Coordination Center (CERT/CC), resides in the way Microsoft Outlook renders remotely-hosted OLE content when an RTF (Rich Text Format) email message is previewed and automatically initiates SMB connections. A remote attacker can exploit this vulnerability by sending an RTF email to a target victim, containing a remotely-hosted image file (OLE object), loading from the attacker-controlled SMB server. Since Microsoft Outlook a

Can you get hacked just by clicking on a malicious link or opening a website? — YES . Microsoft has just released its April month's Patch Tuesday security updates, which addresses multiple critical vulnerabilities in its Windows operating systems and other products, five of which could allow an attacker to hack your computer by just tricking you visit a website. Microsoft has patched five critical vulnerabilities in Windows Graphics Component that reside due to improper handling of embedded fonts by the Windows font library and affects all versions of Windows operating systems to date, including Windows 10 / 8.1 / RT 8.1 / 7, Windows Server 2008 / 2012 / 2016. An attacker can exploit these issues by tricking an unsuspecting user to open a malicious file or a specially crafted website with the malicious font, which if open in a web browser, would hand over control of the affected system to the attacker. All these five vulnerabilities in Windows Microsoft Graphics were dis

A serious vulnerability has been exposed in "emergency alert systems" that could be exploited remotely via radio frequencies to activate all the sirens, allowing hackers to trigger false alarms. The emergency alert sirens are used worldwide to alert citizens about natural disasters, man-made disasters, and emergency situations, such as dangerous weather conditions, severe storms, tornadoes and terrorist attacks. False alarms can create panic and chaos across the city, as witnessed in Dallas last year , when 156 emergency sirens were turned on for about two hours, waking up residents and sparking fears of a disaster. Dubbed " SirenJack Attack ," the vulnerability discovered by a researcher at Bastille security firm affects warning sirens manufactured by Boston-based ATI Systems, which are being used across major towns and cities, as well as Universities, military facilities, and industrial sites. According to Balint Seeber, director of threat research at

A critical remote code execution vulnerability has been discovered in CyberArk Enterprise Password Vault application that could allow an attacker to gain unauthorized access to the system with the privileges of the web application. Enterprise password manager (EPV) solutions help organizations securely manage their sensitive passwords, controlling privileged accounts passwords across a wide range of client/server and mainframe operating systems, switches, databases, and keep them safe from external attackers, as well as malicious insiders. Discovered by German cybersecurity firm RedTeam Pentesting GmbH, the vulnerability affects one of such Enterprise Password Vault apps designed by CyberArk—a password management and security tool that manages sensitive passwords and controls privileged accounts. The vulnerability (CVE-2018-9843) resides in CyberArk Password Vault Web Access, a .NET web application created by the company to help its customers access their accounts remotely.

A critical authentication bypass vulnerability has been discovered in one of the biggest identity-as-a-service platform Auth0 that could have allowed a malicious attacker to access any portal or application, which are using Auth0 service for authentication. Auth0 offers token-based authentication solutions for a number of platforms including the ability to integrate social media authentication into an application. With over 2000 enterprise customers and managing 42 million logins every day and billions of login per month, Auth0 is one of the biggest identity platforms. While pentesting an application back in September 2017, researchers from security firm Cinta Infinita discovered a flaw ( CVE-2018-6873 ) in Auth0's Legacy Lock API , which resides due to improper validation of the JSON Web Tokens (JWT) audience parameter. Researchers successfully exploited this issue to bypass login authentication using a simple cross-site request forgery (CSRF/XSRF) attack against the

Security researchers have discovered three vulnerabilities in the Spring Development Framework, one of which is a critical remote code execution flaw that could allow remote attackers to execute arbitrary code against applications built with it. Spring Framework is a popular, lightweight and an open source framework for developing Java-based enterprise applications. In an advisory released today by Pivotal, the company detailed following three vulnerabilities discovered in Spring Framework versions 5.0 to 5.0.4, 4.3 to 4.3.14, and older unsupported versions: Critical : Remote Code Execution with spring-messaging (CVE-2018-1270) High : Directory Traversal with Spring MVC on Windows (CVE-2018-1271) Low : Multipart Content Pollution with Spring Framework (CVE-2018-1272) Vulnerable Spring Framework versions expose STOMP clients over WebSocket endpoints with an in-memory STOMP broker through the 'spring-messaging' module, which could allow an attacker to send a mali

Security researchers at Embedi have disclosed a critical vulnerability in Cisco IOS Software and Cisco IOS XE Software that could allow an unauthenticated, remote attacker to execute arbitrary code, take full control over the vulnerable network equipment and intercept traffic. The stack-based buffer overflow vulnerability (CVE-2018-0171) resides due to improper validation of packet data in Smart Install Client, a plug-and-play configuration and image-management feature that helps administrators to deploy (client) network switches easily. Embedi has published technical details and Proof-of-Concept (PoC) code after Cisco today released patch updates to address this remote code execution vulnerability, which has been given a base Common Vulnerability Scoring System (CVSS) score of 9.8 (critical). Researchers found a total of 8.5 million devices with the vulnerable port open on the Internet, leaving approximately 250,000 unpatched devices open to hackers. To exploit this vulner

A new vulnerability has been disclosed in iOS Camera App that could be exploited to redirect users to a malicious website without their knowledge. The vulnerability affects Apple's latest iOS 11 mobile operating system for iPhone, iPad, and iPod touch devices and resides in the built-in QR code reader. With iOS 11, Apple introduced a new feature that gives users ability to automatically read QR codes using their iPhone's native camera app without requiring any third-party QR code reader app. You need to open the Camera app on your iPhone or iPad and point the device at a QR code. If the code contains any URL, it will give you a notification with the link address, asking you to tap to visit it in Safari browser. However, be careful — you may not be visiting the URL displayed to you, security researcher Roman Mueller discovered . According to Mueller, the URL parser of built-in QR code reader for iOS camera app fails to detect the hostname in the URL, which allows at

AMD has finally acknowledged 13 critical vulnerabilities, and exploitable backdoors in its Ryzen and EPYC processors disclosed earlier this month by Israel-based CTS Labs and promised to roll out firmware patches for millions of affected devices 'in the coming weeks.' According to CTS-Labs researchers, critical vulnerabilities ( RyzenFall, MasterKey, Fallout, and Chimera ) that affect AMD's Platform Security Processor (PSP) could allow attackers to access sensitive data, install persistent malware inside the chip, and gain full access to the compromised systems. Although exploiting AMD vulnerabilities require admin access, it could help attackers defeat important security features like Windows Credential Guard, TPMs, and virtualization that are responsible for preventing access to the sensitive data from even an admin or root account. In a press release published by AMD on Tuesday, the company downplays the threat by saying that, "any attacker gaining unauthorised ad

You have always been warned not to share remote access to your computer with untrusted people for any reason—it's a basic cybersecurity advice, and common sense, right? But what if, I say you should not even trust anyone who invites or offer you full remote access to their computers. A critical vulnerability has been discovered in Microsoft's Windows Remote Assistanc e (Quick Assist) feature that affects all versions of Windows to date, including Windows 10, 8.1, RT 8.1, and 7, and allows remote attackers to steal sensitive files on the targeted machine. Windows Remote Assistance is a built-in tool that allows someone you trust to take over your PC (or you to take remote control of others) so they can help you fix a problem from anywhere around the world. The feature relies on the Remote Desktop Protocol (RDP) to establish a secure connection with the person in need. However, Nabeel Ahmed of Trend Micro Zero Day Initiative discovered and reported an information di

Researchers found critical vulnerabilities in three popular VPN services that could leak users' real IP addresses and other sensitive data. VPN, or Virtual Private Network , is a great way to protect your daily online activities that work by encrypting your data and boosting security, as well as useful to obscure your actual IP address. While some choose VPN services for online anonymity and data security, one major reason many people use VPN is to hide their real IP addresses to bypass online censorship and access websites that are blocked by their ISPs. But what if when the VPN you thought is protecting your privacy is actually leaking your sensitive data and real location? A team of three ethical hackers hired by privacy advocate firm VPN Mentor revealed that three popular VPN service providers—HotSpot Shield, PureVPN, and Zenmate—with millions of customers worldwide were found vulnerable to flaws that could compromise user's privacy. The team includes applicat

A critical vulnerability has been discovered in Credential Security Support Provider protocol (CredSSP) that affects all versions of Windows to date and could allow remote attackers to exploit RDP and WinRM to steal data and run malicious code. CredSSP protocol has been designed to be used by RDP (Remote Desktop Protocol) and Windows Remote Management (WinRM) that takes care of securely forwarding credentials encrypted from the Windows client to the target servers for remote authentication. Discovered by researchers at Cybersecurity firm Preempt Security, the issue (CVE-2018-0886) is a logical cryptographic flaw in CredSSP that can be exploited by a man-in-the-middle attacker with Wi-Fi or physical access to the network to steal session authentication data and perform a Remote Procedure Call attack. When a client and server authenticate over RDP and WinRM connection protocols, a man-in-the-middle attacker can execute remote commands to compromise enterprise networks. "A

Security researchers have discovered a "kill switch" that could help companies protect their websites under massive DDoS attack launched using vulnerable Memcached servers. Massive Memcached reflection DDoS attacks with an unprecedented amplification factor of 50,000 recently resulted in some of the largest DDoS attacks in history . To make matter even worse, someone released proof-of-concept (PoC) exploit code for Memcached amplification attack yesterday, making it easier for even script kiddies to launch massive cyber attacks. Despite multiple warnings, more than 12,000 vulnerable Memcached servers with UDP support enabled are still accessible on the Internet, which could fuel more cyber attacks soon. However, the good news is that researchers from Corero Network Security found a technique using which DDoS victims can send back a simple command, i.e., "shutdown\r\n", or "flush_all\r\n", in a loop to the attacking Memcached servers in order

Security researchers have discovered a set of severe vulnerabilities in 4G LTE protocol that could be exploited to spy on user phone calls and text messages, send fake emergency alerts, spoof location of the device and even knock devices entirely offline. A new research paper [ PDF ] recently published by researchers at Purdue University and the University of Iowa details 10 new cyber attacks against the 4G LTE wireless data communications technology for mobile devices and data terminals. The attacks exploit design weaknesses in three key protocol procedures of the 4G LTE network known as attach, detach, and paging. Unlike many previous research, these aren't just theoretical attacks. The researchers employed a systematic model-based adversarial testing approach, which they called LTEInspector , and were able to test 8 of the 10 attacks in a real testbed using SIM cards from four large US carriers. Authentication Synchronization Failure Attack Traceability Attack Nu

Facebook Page admins are publicly displayed only if admins have chosen to feature their profiles. However, there are some situations where you might want to contact a Facebook page admin or want to find out who is the owner of a Facebook page. Egyptian security researcher Mohamed A. Baset has discovered a severe information disclosure vulnerability in Facebook that could have allowed anyone to expose Facebook page administrator profiles, which is otherwise not supposed to be public information. Baset claimed to have discovered the vulnerability in less than 3 minutes without any kind of testing or proof of concepts, or any other type of time-consuming processes. In a blog post , Baset said he found the vulnerability, which he described as a "logical error," after receiving an invitation to like a particular Facebook page on which he had previously liked a post. Facebook has introduced a feature for page admins wherein they can send Facebook invitations to users

Bitmessage developers have warned of a critical 'remotely executable' zero-day vulnerability in the PyBitmessage application that was being exploited in the wild. Bitmessage is a Peer-to-Peer (P2P) communications protocol used to send encrypted messages to users. Since it is decentralized and trustless communications, one need-not inherently trust any entities like root certificate authorities. Those who unaware, PyBitmessage is the official client for Bitmessage messaging service. According to Bitmessage developers, a critical zero-day remote code execution vulnerability, described as a message encoding flaw, affects PyBitmessage version 0.6.2 for Linux, Mac, and Windows and has been exploited against some of their users. "The exploit is triggered by a malicious message if you are the recipient (including joined chans). The attacker ran an automated script but also opened, or tried to open, a remote reverse shell," Bitmessage core developer Peter Šurda ex
