A now-patched security flaw in the Microsoft Edge web browser could have been abused to install arbitrary extensions on users' systems and carry out malicious actions.  "This flaw could have allowed an attacker to exploit a private API, initially intended for marketing purposes, to covertly install additional browser extensions with broad permissions without the user's knowledge," Guardio Labs security researcher Oleg Zaytsev  said  in a new report shared with The Hacker News. Tracked as  CVE-2024-21388  (CVSS score: 6.5), it was addressed by Microsoft in Edge stable version 121.0.2277.83 released on January 25, 2024, following responsible disclosure in November 2023. The Windows maker credited both Zaytsev and Jun Kokatsu for reporting the issue. "An attacker who successfully exploited this vulnerability could gain the privileges needed to install an extension," Microsoft said in an advisory for the flaw, adding it "could lead to a browser sandbo

Apple has  released  software updates for iOS, iPadOS, macOS, and Safari web browser to address two security flaws that it said have come under active exploitation in the wild on older versions of its software. The vulnerabilities, both of which reside in the WebKit web browser engine, are described below - CVE-2023-42916  - An out-of-bounds read issue that could be exploited to leak sensitive information when processing web content. CVE-2023-42917  - A memory corruption bug that could result in arbitrary code execution when processing web content. Apple said it's aware of reports exploiting the shortcomings "against versions of iOS before iOS 16.7.1," which was released on October 10, 2023. Clément Lecigne of Google's Threat Analysis Group (TAG) has been credited with discovering and reporting the twin flaws. The iPhone maker did not provide additional information regarding ongoing exploitation, but previously disclosed zero-days in iOS have been used to  de

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

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,

New details have emerged about a vast network of rogue extensions for Chrome and Edge browsers that were found to hijack clicks to links in search results pages to arbitrary URLs, including phishing sites and ads. Collectively called " CacheFlow " by Avast, the 28 extensions in question — including Video Downloader for Facebook, Vimeo Video Downloader, Instagram Story Downloader, VK Unblock — made use of a sneaky trick to mask its true purpose: Leverage  Cache-Control  HTTP header as a covert channel to retrieve commands from an attacker-controlled server. All the  backdoored browser add-ons  have been taken down by Google and Microsoft as of December 18, 2020, to prevent more users from downloading them from the official stores. According to telemetry data gathered by the firm, the top three infected countries were Brazil, Ukraine, and France, followed by Argentina, Spain, Russia, and the U.S. The CacheFlow sequence began when unsuspecting users downloaded one of the
