DHS Orders Federal Agencies to Patch Critical Flaws Within 15 Days

DHS Orders Federal Agencies to Patch Critical Flaws Within 15 Days

May 01, 2019Mohit Kumar
In recent years, we have seen how hackers prey on those too lazy or ignorant to install security patches, which, if applied on time, would have prevented some devastating cyber attacks and data breaches that happened in major organisations. The United States Department of Homeland Security (DHS) has ordered government agencies to more swiftly plug the critical security vulnerabilities found on their networks within 15 calendar days since the initial detection, a reduction from 30 days. DHS's Cybersecurity and Infrastructure Security Agency (CISA) this week issued a new Binding Operational Directive (BOD) 19-02 instructing federal agencies and departments to address "critical" rated vulnerabilities within 15 days and "high" severity flaws within 30 days of initial detection. The countdown to patch a security vulnerability will start when it was initially detected during CISA's weekly Cyber Hygiene vulnerability scanning, rather than it was the firs
'Highly Critical' Unpatched Zero-Day Flaw Discovered In Oracle WebLogic

'Highly Critical' Unpatched Zero-Day Flaw Discovered In Oracle WebLogic

April 25, 2019Mohit Kumar
A team of cybersecurity researchers today published a post warning enterprises of an unpatched, highly critical zero-day vulnerability in Oracle WebLogic server application that some attackers might have already started exploiting in the wild. Oracle WebLogic is a scalable, Java-based multi-tier enterprise application server that allows businesses to quickly deploy new products and services on the cloud. It's popular across both, cloud environment and conventional environments. Oracle WebLogic application reportedly contains a critical deserialization remote code execution vulnerability that affects all versions of the software, which can be triggered if the "wls9_async_response.war" and "wls-wsat.war" components are enabled. The vulnerability, spotted by the researchers from KnownSec 404, allows attackers to remotely execute arbitrary commands on the affected servers just by sending a specially crafted HTTP request—without requiring any authorization.

Apache Tomcat Patches Important Remote Code Execution Flaw

April 15, 2019Wang Wei
The Apache Software Foundation (ASF) has released new versions of its Tomcat application server to address an important security vulnerability that could allow a remote attacker to execute malicious code and take control of an affected server. Developed by ASF, Apache Tomcat is an open source web server and servlet system, which uses several Java EE specifications such as Java Servlet, JavaServer Pages (JSP), Expression Language, and WebSocket to provide a "pure Java" HTTP web server environment for Java concept to run in. The remote code execution vulnerability ( CVE-2019-0232 ) resides in the Common Gateway Interface (CGI) Servlet when running on Windows with enableCmdLineArguments enabled and occurs due to a bug in the way the Java Runtime Environment (JRE) passes command line arguments to Windows. Since the CGI Servlet is disabled by default and its option enableCmdLineArguments is disabled by default in Tomcat 9.0.x, the remote code execution vulnerability has
Security Flaws in WPA3 Protocol Let Attackers Hack WiFi Password

Security Flaws in WPA3 Protocol Let Attackers Hack WiFi Password

April 10, 2019Swati Khandelwal
🔥 Breaking — It has been close to just one year since the launch of next-generation Wi-Fi security standard WPA3 and researchers have unveiled several serious vulnerabilities in the wireless security protocol that could allow attackers to recover the password of the Wi-Fi network. WPA, or Wi-Fi Protected Access, is a standard designed to authenticate wireless devices using the Advanced Encryption Standard (AES) protocol and is intended to prevent hackers from eavesdropping on your wireless data. The Wi-Fi Protected Access III (WPA3) protocol was launched in an attempt to address technical shortcomings of the WPA2 protocol from the ground, which has long been considered to be insecure and found vulnerable to KRACK (Key Reinstallation Attack). Though WPA3 relies on a more secure handshake, known as Dragonfly , that aims to protect Wi-Fi networks against offline dictionary attacks, security researchers Mathy Vanhoef and Eyal Ronen found weaknesses in the early implementation

Hackers Could Turn Pre-Installed Antivirus App on Xiaomi Phones Into Malware

April 04, 2019Swati Khandelwal
What could be worse than this, if the software that's meant to protect your devices leave backdoors open for hackers or turn into malware? Researchers today revealed that a security app that comes pre-installed on more than 150 million devices manufactured by Xiaomi, China's biggest and world's 4th largest smartphone company, was suffering from multiple issues that could have allowed remote hackers to compromise Xiaomi smartphones. According to CheckPoint, the reported issues resided in one of the pre-installed application called, Guard Provider , a security app developed by Xiaomi that includes three different antivirus programs packed inside it, allowing users to choose between Avast, AVL, and Tencent. Since Guard Provider has been designed to offer multiple 3rd-party programs within a single app, it uses several Software Development Kits (SDKs), which according to researchers is not a great idea because data of one SDK cannot be isolated and any issue in one of

Unpatched Zero-Days in Microsoft Edge and IE Browsers Disclosed Publicly

March 30, 2019Mohit Kumar
Exclusive — A security researcher today publicly disclosed details and proof-of-concept exploits for two 'unpatched' zero-day vulnerabilities in Microsoft's web browsers after the company allegedly failed to respond to his responsible private disclosure. Both unpatched vulnerabilities—one of which affects the latest version of Microsoft Internet Explorer and another affects the latest Edge Browser —allow a remote attacker to bypass same-origin policy on victim's web browser. Same Origin Policy (SOP) is a security feature implemented in modern browsers that restricts a web-page or a script loaded from one origin to interact with a resource from another origin, preventing unrelated sites from interfering with each other. In other words, if you visit a website on your web browser, it can only request data from the same origin [domain] the site was loaded from, preventing it from making any unauthorized request on your behalf in order to steal your data, from othe

Medtronic's Implantable Defibrillators Vulnerable to Life-Threatening Hacks

March 22, 2019Swati Khandelwal
The U.S. Department of Homeland Security Thursday issued an advisory warning people of severe vulnerabilities in over a dozen heart defibrillators that could allow attackers to fully hijack them remotely, potentially putting lives of millions of patients at risk. Cardioverter Defibrillator is a small surgically implanted device (in patients' chests) that gives a patient's heart an electric shock (often called a countershock) to re-establish a normal heartbeat. While the device has been designed to prevent sudden death, several implanted cardiac defibrillators made by one of the world's largest medical device companies Medtronic have been found vulnerable to two serious vulnerabilities. Discovered by researchers from security firm Clever Security, the vulnerabilities could allow threat actors with knowledge of medical devices to intercept and potentially impact the functionality of these life-saving devices.

Patched WinRAR Bug Still Under Active Attack—Thanks to No Auto-Updates

March 15, 2019Swati Khandelwal
Various cyber criminal groups and individual hackers are still exploiting a recently patched critical code execution  vulnerability in WinRAR , a popular Windows file compression application with 500 million users worldwide. Why? Because the WinRAR software doesn't have an auto-update feature, which, unfortunately, leaves millions of its users vulnerable to cyber attacks. The critical vulnerability (CVE-2018-20250) that was patched late last month by the WinRAR team with the release of WinRAR version 5.70 beta 1 impacts all prior versions of WinRAR released over the past 19 years. For those unaware, the vulnerability is "Absolute Path Traversal" bug that resides in the old third-party library UNACEV2.DLL of WinRAR and allows attackers to extract a compressed executable file from the ACE archive to one of the Windows Startup folders, where the malicious file would automatically run on the next reboot. Therefore, to successfully exploit this vulnerability and tak

New Flaws Re-Enable DMA Attacks On Wide Range of Modern Computers

February 27, 2019Mohit Kumar
Security researchers have discovered a new class of security vulnerabilities that impacts all major operating systems, including Microsoft Windows, Apple macOS, Linux, and FreeBSD, allowing attackers to bypass protection mechanisms introduced to defend against DMA attacks. Known for years, Direct memory access (DMA)-based attacks let an attacker compromise a targeted computer in a matter of seconds by plugging-in a malicious hot plug device—such as an external network card, mouse, keyboard, printer, storage, and graphics card—into Thunderbolt 3 port or the latest USB-C port . The DMA-based attacks are possible because Thunderbolt port allows connected peripherals to bypass operating system security policies and directly read/write system memory that contains sensitive information including your passwords, banking logins, private files, and browser activity. That means, simply plugging in an infected device, created using tools like Interception , can manipulate the contents o

Warning: Critical WinRAR Flaw Affects All Versions Released In Last 19 Years

February 21, 2019Swati Khandelwal
Beware Windows users... a new dangerous remote code execution vulnerability has been discovered in the WinRAR software, affecting hundreds of millions of users worldwide. Cybersecurity researchers at Check Point have disclosed technical details of a critical vulnerability in WinRAR—a popular Windows file compression application with 500 million users worldwide—that affects all versions of the software released in last 19 years. The flaw resides in the way an old third-party library, called UNACEV2.DLL, used by the software handled the extraction of files compressed in ACE data compression archive file format. However, since WinRAR detects the format by the content of the file and not by the extension, attackers can merely change the .ace extension to .rar extension to make it look normal. According to researchers, they found an "Absolute Path Traversal" bug in the library that could be leveraged to execute arbitrary code on a targeted system attempting to uncompre
