10 Major Vulnerabilities Identified in CODESYS Industrial Automation Software

Cybersecurity researchers revealed ten significant flaws in CODESYS automation software that could allow remote code execution on programmable logic controllers (PLCs). According to experts from Positive Technologies, an attacker requires only network access to exploit these vulnerabilities—no username or password is necessary. The root cause lies in inadequate input data verification, often due to non-adherence to secure development practices. The Russian cybersecurity firm identified these flaws in a PLC produced by WAGO, which, along with other automation companies like Beckhoff, Kontron, Moeller, Festo, Mitsubishi, and HollySys, utilizes CODESYS software for programming and configuring their controllers. CODESYS provides a development environment for programming controller applications.

Instagram Bug Exposed Private Accounts, Allowing Unfettered Access to Archived Content

June 15, 2021

Instagram has resolved a significant vulnerability that permitted anyone to access archived posts and stories from private accounts without needing to follow them. Security researcher Mayur Fartade revealed in a Medium post today that “this bug could have allowed a malicious user to view targeted media on Instagram.” By leveraging the Media ID, an attacker could see details of private posts, stories, reels, and IGTV videos without following the user. Fartade reported the issue to Facebook’s security team on April 16, 2021, and the flaw was patched on June 15, leading to a $30,000 reward for his efforts through the company’s bug bounty program. Although exploiting this vulnerability required knowledge of the media ID, Fartade demonstrated that by brute-forcing the identifiers, it was feasible to send a POST request to a GraphQL endpoint and access sensitive information. As a result of this flaw, details like likes, comments, and saves could have been exposed.

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.

NVIDIA Jetson Chipsets Vulnerable to Critical Security Flaws

On June 22, 2021, U.S. graphics chip manufacturer NVIDIA issued software updates to patch 26 vulnerabilities in its Jetson system-on-module (SOM) lineup. These flaws could allow attackers to escalate privileges and potentially cause denial-of-service or information disclosure issues. Ranging from CVE‑2021‑34372 to CVE‑2021‑34397, the vulnerabilities impact several Jetson products, including the TX1, TX2 series, TX2 NX, AGX Xavier series, Xavier NX, and Nano, as well as the Nano 2GB, all running Jetson Linux versions prior to 32.5.1. The issues were reported by Frédéric Perriot of Apple Media Products. NVIDIA’s Jetson line is designed for AI and computer vision applications, catering primarily to autonomous systems and mobile robots. A major concern is CVE‑2021‑34372, a buffer overflow vulnerability in the Trusty trusted execution environment (TEE) with a CVSS score of 8.2.
