Google Chrome Bug Could Let Hackers Bypass CSP Protection; Update Web Browsers

Google Chrome Bug Could Let Hackers Bypass CSP Protection; Update Web Browsers

Aug 11, 2020
If you haven't recently updated your Chrome, Opera, or Edge web browser to the latest available version, it would be an excellent idea to do so as quickly as possible. Cybersecurity researchers on Monday disclosed details about a zero-day flaw in Chromium-based web browsers for Windows, Mac and Android that could have allowed attackers to entirely bypass Content Security Policy (CSP) rules since Chrome 73. Tracked as CVE-2020-6519 (rated 6.5 on the CVSS scale), the issue stems from a CSP bypass that results in arbitrary execution of malicious code on target websites. According to PerimeterX, some of the most popular websites, including Facebook, Wells Fargo, Zoom, Gmail, WhatsApp, Investopedia, ESPN, Roblox, Indeed, TikTok, Instagram, Blogger, and Quora, were susceptible to the CSP bypass. Interestingly, it appears that the same flaw was also highlighted by Tencent Security Xuanwu Lab more than a year ago, just a month after the release of Chrome 73 in March 2019, but
Beware! Unpatched Safari Browser Hack Lets Attackers Spoof URLs

Beware! Unpatched Safari Browser Hack Lets Attackers Spoof URLs

Sep 12, 2018
A security researcher has discovered a serious vulnerability that could allow attackers to spoof website addresses in the Microsoft Edge web browser for Windows and Apple Safari for iOS. While Microsoft fixed the address bar URL spoofing vulnerability last month as part of its monthly security updates , Safari is still unpatched, potentially leaving Apple users vulnerable to phishing attacks. The phishing attacks today are sophisticated and increasingly more difficult to spot, and this newly discovered vulnerability takes it to another level that can bypass basic indicators like URL and SSL, which are the first things a user checks to determine if a website is fake. Discovered by Pakistan-based security researcher Rafay Baloch, the vulnerability (CVE-2018-8383) is due to a race condition type issue caused by the web browser allowing JavaScript to update the page address in the URL bar while the page is loading. Here's How the URL Spoofing Vulnerability Works Successfu
How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte
Update Google Chrome Immediately to Patch a High Severity Vulnerability

Update Google Chrome Immediately to Patch a High Severity Vulnerability

Jun 06, 2018
You must update your Google Chrome now. Security researcher Michał Bentkowski discovered and reported a high severity vulnerability in Google Chrome in late May, affecting the web browsing software for all major operating systems including Windows, Mac, and Linux. Without revealing any technical detail about the vulnerability, the Chrome security team described the issue as incorrect handling of CSP header ( CVE-2018-6148 ) in a blog post published today. "Access to bug details and links may be kept restricted until a majority of users are updated with a fix. We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven't yet fixed," the Chrome security team notes. Content Security Policy (CSP) header allows website administrators to add an extra layer of security on a given web page by allowing them to control resources the browser is allowed to load. Mishandling of CSP headers by your web brow

Update Your Firefox Browser to Fix a Critical Remotely Exploitable Flaw

Update Your Firefox Browser to Fix a Critical Remotely Exploitable Flaw

Jan 31, 2018
Mozilla has released an important update for its Firefox web browser to patch a critical vulnerability that could allow remote attackers to execute malicious code on computers running an affected version of the browser. The update comes just a week after the company rolled out its new Firefox Quantum browser, a.k.a Firefox 58, with some new features like improved graphics engine and performance optimizations and patches for more than 30 vulnerabilities. According to a security advisory published by Cisco, Firefox 58.0.1 addresses an 'arbitrary code execution' flaw that originates due to 'insufficient sanitization' of HTML fragments in chrome-privileged documents (browser UI). Hackers could exploit this vulnerability (CVE-2018-5124) to run arbitrary code on the victim's computer just by tricking them into accessing a link or ' opening a file that submits malicious input to the affected software .' "A successful exploit could allow the attacker t

Critical RCE Vulnerability Found in Cisco WebEx Extensions, Again — Patch Now!

Jul 17, 2017
A highly critical vulnerability has been discovered in the Cisco Systems' WebEx browser extension for Chrome and Firefox, for the second time in this year, which could allow attackers to remotely execute malicious code on a victim's computer. Cisco WebEx is a popular communication tool for online events, including meetings, webinars and video conferences that help users connect and collaborate with colleagues around the world. The extension has roughly 20 million active users. Discovered by Tavis Ormandy of Google Project Zero and Cris Neckar of Divergent Security, the remote code execution flaw (CVE-2017-6753) is due to a designing defect in the WebEx browser extension. To exploit the vulnerability, all an attacker need to do is trick victims into visiting a web page containing specially crafted malicious code through the browser with affected extension installed. Successful exploitation of this vulnerability could result in the attacker executing arbitrary code with th

A Simple JavaScript Exploit Bypasses ASLR Protection On 22 CPU Architectures

Feb 16, 2017
Security researchers have discovered a chip flaw that could nullify hacking protections for millions of devices regardless of their operating system or application running on them, and the worse — the flaw can not be entirely fixed with any mere software update. The vulnerability resides in the way the memory management unit (MMU), a component of many CPUs, works and leads to bypass the Address Space Layout Randomization (ASLR) protection. ASLR is a crucial security defense deployed by all modern operating systems from Windows and Linux to macOS, Android, and the BSDs. In general, ASLR is a memory protection mechanism which randomizes the location where programs run in a device's memory. This, in turn, makes it difficult for attackers to execute malicious payloads in specific spots in memory when exploiting buffer overflows or similar bugs. In short, for attackers, it's like an attempt to burglarize a house blindfolded. But now a group of researchers, known as VUSe
Browser AutoFill Feature Can Leak Your Personal Information to Hackers

Browser AutoFill Feature Can Leak Your Personal Information to Hackers

Jan 11, 2017
Just like most of you, I too really hate filling out web forms, especially on mobile devices. To help make this whole process faster, Google Chrome and other major browsers offer "Autofill" feature that automatically fills out web form based on data you have previously entered in similar fields. However, it turns out that an attacker can use this autofill feature against you and trick you into spilling your private information to hackers or malicious third parties. Finnish web developer and whitehat hacker Viljami Kuosmanen published a demo on GitHub that shows how an attacker could take advantage of the autofill feature provided by most browsers, plugins, and tools such as Password Managers. Although, this trick was first discovered by Ricardo Martin Rodriguez , Security Analyst at ElevenPaths, in the year 2013, but it seems Google haven't done anything to address weakness in Autofill feature. The proof-of-concept demo website consists of a simple online
