RCE Zero Day Vulnerabilities in CUPS Put Linux Systems at Risk

A new series of vulnerabilities in the Common Unix Printing System (CUPS) threatens numerous Linux systems, potentially allowing remote code execution (RCE). This affects a wide range of platforms, including Debian, Red Hat, SUSE and macOS. The vulnerabilities—tracked as CVE-2024-47176, CVE-2024-47076, CVE-2024-47175, and CVE-2024-47177—are believed to endanger over 76,000 devices, with estimates suggesting up to 300,000 could be affected.

Exploiting trust: Weaponizing permissive CORS configurations

If you’re a pentester, or a consumer of application security pentest reports, you’ll probably have come across Cross-Origin Resource Sharing (CORS) and its commonly associated misconfigurations. In either case, you’ll likely have quickly dismissed the finding because it resulted in yet another “recommendation” (a vulnerability without any impact).

Going beyond reachability to prioritize what matters most

Most modern applications contain a substantial number of open source packages, libraries, and frameworks. In fact, it's estimated that at least 80% of the source code in modern applications is from open source. In addition to relying heavily on commodity components to build applications, development teams often deploy these apps and services via community-sourced container base images.

A Case Study in Vulnerability Prioritization: Lessons Learned from Large-Scale Incidents

There’s no way around it: vulnerability management is complex. As organizations become more reliant on software and applications, the sheer volume of known vulnerabilities has become more difficult to track, prioritize, and remediate. Adversaries have also become increasingly reliant on exploiting vulnerabilities in order to compromise organizations.

Critical Vulnerabilities Uncovered: How Bitsight Delivered Fast, Actionable Insights in Under 24 Hours

The speed at which vulnerabilities are detected and addressed can drastically impact an organization’s likelihood of suffering a security incident. Recently, Bitsight demonstrated how its investments in product fingerprinting and CVE mapping allowed it to identify and surface assets potentially impacted by a set of critical vulnerabilities in the CUPS printing system in under 24 hours.

Breaking Down the OWASP Top 10 API Security Risks 2023 (& What Changed From 2019)

The OWASP Top Ten lists have been the cornerstone for application security best practices for over two decades. The 2019 list was the first edition of the OWASP API Security Top 10. The latest, OWASP API Security Top 10 2023, gives our security and engineering teams a glimpse of attack vectors that are becoming more common. With that in mind, it also helps our security teams to ensure that they have adequate coverage for security testing.

The CUPS Vulnerability- The 443 Podcast - Episode 308

This week on the podcast, we cover the "9.9/10 severity vulnerability affecting most Linux systems" that a researcher disclosed last week and what it means for Linux systems administrators. We then discuss a research post into Kia's remote control systems that allowed one researcher to compromise any Kia in the last decade by just knowing their license plate number. We end with a new act that was just introduced into the US Senate with a goal to secure the healthcare industry.

What We Know So Far About Zero-Day CUPS Vulnerabilities: CVE-2024-47176, CVE-2024-47076, CVE-2024-47175, and CVE-2024-47177

On September 26, 2024, security researcher Simone Margaritellidisclosed the details of four OpenPrinting Common UNIX Printing System (CUPS) vulnerabilities, that, when chained together, can allow malicious actors to launch remote code execution (RCE) attacks on vulnerable systems. CUPS is a widely used, open-source printing system that supports Linux and other Unix-like operating systems. It also supports ChromeOS and macOS.
