This WhatsApp Bug Could Have Let Attackers Access Files On Your PCs
February 04, 2020Mohit Kumar
A cybersecurity researcher today disclosed technical details of multiple high severity vulnerabilities he discovered in WhatsApp, which, if exploited, could have allowed remote attackers to compromise the security of billions of users in different ways. When combined together, the reported issues could have even enabled hackers to remotely steal files from the Windows or Mac computer of a victim using the WhatsApp desktop app by merely sending a specially crafted message. Discovered by PerimeterX researcher Gal Weizman and tracked as CVE-2019-18426 , the flaws specifically resided in WhatsApp Web, a browser version of the world's most popular messaging application that also powers its Electron-based cross-platform apps for desktop operating systems. In a blog post published today, Weizman revealed that WhatsApp Web was vulnerable to a potentially dangerous open-redirect flaw that led to persistent cross-site scripting attacks, which could have been triggered by sending a s

Simple bug could lead to RCE flaw on apps built with Electron Framework

Simple bug could lead to RCE flaw on apps built with Electron Framework

A critical remote code execution vulnerability has been discovered in the popular Electron web application framework that could allow attackers to execute malicious code on victims' computers. Electron is an open source app development framework that powers thousands of widely-used desktop applications including WhatsApp, Skype, Signal, Wordpress, Slack, GitHub Desktop, Atom, Visual Studio Code, and Discord. Besides its own modules, Electron framework also allows developers to create hybrid desktop applications by integrating Chromium and Node.js framework through APIs. Since Node.js is a robust framework for server-side applications, having access to its APIs indirectly gives Electron-based apps more control over the operating system installed on the server. To prevent unauthorised or unnecessary access to Node.js APIs, Electron framework by default sets the value of "webviewTag" to false in its "webPreferences" configuration file, which then sets &

A critical remote code execution vulnerability has been reported in Electron —a popular web application framework that powers thousands of widely-used desktop applications including Skype, Signal, Wordpress and Slack—that allows for remote code execution. Electron is an open-source framework that is based on Node.js and Chromium Engine and allows app developers to build cross-platform native desktop applications for Windows, macOS and Linux, without knowledge of programming languages used for each platform. The vulnerability, assigned as the number CVE-2018-1000006, affects only those apps that run on Microsoft Windows and register themselves as the default handler for a protocol like myapp://. "Such apps can be affected regardless of how the protocol is registered, e.g. using native code, the Windows registry, or Electron's app.setAsDefaultProtocolClient API," Electron says in an advisory published Monday. The Electron team has also confirmed that applications
