Mitsubishi | Breaking Cybersecurity News | The Hacker News

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) this week released an Industrial Control Systems (ICS) advisory warning of multiple vulnerabilities in Mitsubishi Electric GX Works3 engineering software. "Successful exploitation of these vulnerabilities could allow unauthorized users to gain access to the MELSEC iQ-R/F/L series CPU modules and the MELSEC iQ-R series OPC UA server module or to view and execute programs," the agency  said . GX Works3  is an  engineering workstation  software used in ICS environments, acting as a mechanism for uploading and downloading programs from/to the controller, troubleshooting software and hardware issues, and performing maintenance operations. The wide range of functions also makes the platform an attractive target for threat actors looking to compromise such systems to commandeer the  managed PLCs . Three of the 10 shortcomings relate to cleartext storage of sensitive data, four relate to the use of a...

Multiple unpatched security vulnerabilities have been disclosed in Mitsubishi safety programmable logic controllers (PLCs) that could be exploited by an adversary to acquire legitimate user names registered in the module via a brute-force attack, unauthorizedly login to the CPU module, and even cause a denial-of-service (DoS) condition. The security weaknesses, disclosed by  Nozomi Networks , concern the implementation of an authentication mechanism in the  MELSEC communication protocol  that's used to communicate and exchange data with the target devices by reading and writing data to the CPU module. A quick summary of the flaws is listed below - Username Brute-force (CVE-2021-20594, CVSS score: 5.9) - Usernames used during authentication are effectively brute-forceable Anti-password Brute-force Functionality Leads to Overly Restrictive Account Lockout Mechanism (CVE-2021-20598, CVSS score: 3.7) - The implementation to thwart brute-force attacks not only blo...

It's time once again to pay our respects to the once-famous cybersecurity solutions whose usefulness died in the past year. The cybercriminal world collectively mourns the loss of these solutions and the easy access they provide to victim organizations. These solutions, though celebrated in their prime, succumbed to the twin forces of time and advancing threats. Much like a tribute to celebrities lost in the past year, this article will look back at a few of cybersecurity's brightest stars that went dark in the past year.  1. Legacy Multi-Factor Authentication (MFA) Cause of Death: Compromised by sophisticated phishing, man-in-the-middle (MitM), SIM-swapping, and MFA prompt bombing attacks. The superstar of access security for more than twenty years, legacy MFA solutions enjoyed broad adoption followed by almost-universal responsibility for cybersecurity failures leading to successful ransomware attacks. These outdated solutions relied heavily on SMS or email-based codes o...
