Vulnerabilities in Two Major WordPress Plugins Impact Over 7 Million Sites

On March 18, 2021, researchers revealed security flaws in several WordPress plugins, which, if exploited, could enable attackers to execute arbitrary code and potentially take control of affected websites. The vulnerabilities were found in Elementor, a widely-used website builder plugin installed on more than seven million sites, and WP Super Cache, a popular tool for serving cached pages on WordPress. According to Wordfence, which identified the weaknesses in Elementor, the issue involves a series of stored cross-site scripting (XSS) vulnerabilities (CVSS score: 6.4). This occurs when malicious scripts are injected directly into a vulnerable web application. Specifically, the lack of server-side validation for HTML tags allows an attacker to inject executable JavaScript into posts or pages through crafted requests. “Since posts created by contributors are usually reviewed by editors or administrators before publication, any JavaScript added to one of the…

Urgent: Update Your Chrome Browser Immediately to Fix Recently Discovered Vulnerability

Google has released a critical update for the Chrome web browser across Windows, Mac, and Linux, addressing seven security issues, including one actively exploited flaw. Identified as CVE-2021-21224, this vulnerability arises from a type confusion problem in the V8 JavaScript engine, reported by security researcher Jose Martinez on April 5. Security expert Lei Cao explains that the bug occurs during integer type conversion, leading to an out-of-bounds condition that could allow arbitrary memory read/write access. “Google is aware of reports indicating that exploits for CVE-2021-21224 are in the wild,” stated Chrome’s Technical Program Manager, Srinivas Sista, in a recent blog post. This update follows the release of proof-of-concept code by a researcher named “frust” on April 14, highlighting the urgency of addressing this issue.

Urgent: Update Your Chrome Browser to Address New 0-Day Vulnerability

June 18, 2021

Google has released an important update for the Chrome browser on Windows, Mac, and Linux to resolve four security vulnerabilities, including a critical zero-day flaw currently being exploited. This issue, identified as CVE-2021-30554, is a high-severity “use after free” vulnerability in WebGL (Web Graphics Library), which is a JavaScript API used for rendering interactive 2D and 3D graphics in the browser. Exploiting this flaw could lead to data corruption, crashes, and unauthorized execution of code or commands. Google received an anonymous report about the vulnerability on June 15, and Chrome technical program manager Srinivas Sista confirmed that the company is “aware that an exploit for CVE-2021-30554 exists in the wild.” While it’s standard practice to withhold specific details until most users have applied the fix, this announcement comes just days after Google addressed another zero-day vulnerability.

New ‘Trojan Source’ Technique Allows Hackers to Conceal Vulnerabilities in Source Code

November 1, 2021

A groundbreaking class of vulnerabilities has emerged, enabling threat actors to inject misleading malware that technically adheres to coding logic while distorting its intended functionality. Known as “Trojan Source attacks,” this method exploits nuances in text-encoding standards like Unicode, allowing the arrangement of source code tokens to differ from their displayed order. This results in vulnerabilities that evade detection by human reviewers, according to researchers Nicholas Boucher and Ross Anderson from Cambridge University, who outlined the findings in a recent paper. These vulnerabilities, identified as CVE-2021-42574 and CVE-2021-42694, impact compilers across numerous widely-used programming languages, including C, C++, C#, JavaScript, Java, Rust, Go, and Python. Compilers are essential tools that convert high-level human-readable code into executable machine code.
