TL; DR – Multiple versions of OpenSSH are vulnerable to remote code execution. There is no working public PoC, and researchers have only been able to exploit the vulnerability under unique lab conditions. Cato Sockets by default do NOT have a publicly exposed SSH interface, it is always recommended to keep Cato Sockets LAN interface exposed only internally and use comprehensive network access controls to manage SSH access.

A high-severity remote code execution (RCE) vulnerability, CVE-2024-6387, has been discovered in OpenSSH’s server by the Qualys research team. This vulnerability is particularly concerning as it revives an issue that was previously addressed in 2006, highlighting the persistence of hidden bugs in widely used secure software. This discovery follows another significant vulnerability in the XZ Utils library found just a few months ago, underscoring ongoing security challenges.

Held in Breda, Netherlands, this year’s Cyber Resilience Day convened industry leaders and cybersecurity experts to address the topic of supply chain attacks and the latest digital threats. The event showcased a series of keynote speeches, panel discussions, and interactive workshops, equipping attendees with valuable insights and actionable strategies to strengthen their organizations’ cyber resilience.

For over a decade, a massive vulnerability that could have unleashed a huge supply chain attack lay dormant. Luckily the good guys found it first or so it seems. This month we are taking a look at CVE-2024-38368.

Blockchain technology, renowned for its decentralized and immutable nature, promises enhanced security for various applications. However, like any technology, it is not without vulnerabilities. This in-depth examination explores the security aspects of blockchain, identifies common vulnerabilities, and outlines the measures needed to secure blockchain applications effectively.

A critical chained vulnerability (CVE-2024-47076, CVE-2024-47175, CVE-2024-47176, and CVE-2024-47177) has been detected within the open-source printing system CUPS (present in most Linux distributions). Attackers can achieve remote code execution, potentially leading to complete control of the vulnerable system. Detectify customers can assess whether their systems are running affected versions of CUPS.

A critical vulnerability in GitLab, a widely-used Git repository platform, has been discovered, threatening the integrity of software development pipelines. GitLab has urged users running vulnerable versions to patch CVE-2024-5655 immediately to prevent potential CI/CD malfeasance. GitLab's Latest Security Patch GitLab, second only to GitHub in popularity, recently released updates for its Community (open source) and Enterprise Editions.

On July 1, 2024, OpenSSH released fixes for CVE-2024-6387, a vulnerability in OpenSSH’s server (sshd) on glibc-based Linux systems allowing for potential Remote Code Execution (RCE). OpenSSH is a widely-used suite of secure networking tools based on the SSH protocol, providing encryption for secure communication and file transfers, and is essential for remote management on Unix systems. CVE-2024-6387 is a signal handler race condition that allows unauthenticated Remote Code Execution (RCE) as root.

OpenSSH, an application installed by default on nearly every Unix-like and Linux system, has recently come under scrutiny due to a critical vulnerability discovered by Qualys. Designated as CVE-2024-6387 and aptly named "regreSSHion," this flaw exposes Linux environments to remote unauthenticated code execution. The implications of this vulnerability are far-reaching, potentially affecting countless servers and infrastructure components across the globe.

On June 28, 2024, Juniper released fixes for a critical authentication bypass vulnerability discovered during internal testing, CVE-2024-3937. Juniper has stated that this vulnerability affects only Session Smart Router (SSR), Session Smart Conductor, and WAN Assurance Router products running in high-availability redundant configurations.
