In the realm of cybersecurity, there's a common analogy that likens the process to a health checkup. Vulnerability scanning, in this context, can be seen as a basic health screening. It's a preliminary step, offering a snapshot of potential issues within a system. It's like getting your blood pressure or cholesterol checked during a routine visit to the doctor. These tests are essential, providing a quick overview of potential health concerns. But they don't give the full picture.

Welcome to the 12th post in our weekly series on the new 2023 OWASP API Security Top-10 list, with a particular focus on security practitioners. In this series we are taking an in-depth look at each category – the details, the impact and what you can do about it. To see previous posts you might have missed, click here. This post will put a spotlight on Injection, which used to be its own category (OWASP API8:2019) but has now been subsumed into OWASP API10:2023 (Unsafe Consumption of APIs).

A new critical vulnerability has been disclosed by Atlassian in a security advisory published on October 4th 2023 in its on-premise Confluence Data Center and Server product. A privilege escalation vulnerability through which attackers may exploit a vulnerable endpoint in internet-facing Confluence instances to create unauthorized Confluence administrator accounts and gain access to the Confluence instance.

Due to the increasing frequency and impact of cybersecurity threats, vulnerability management has become a heightened priority for many organizations. While businesses often focus on vulnerability assessments when developing their vulnerability management programs, assessments are only the first step in a holistic cybersecurity threat mitigation strategy. One aspect of vulnerability management that is often overlooked is vulnerability remediation.

At Cloudflare, we're constantly vigilant when it comes to identifying vulnerabilities that could potentially affect the Internet ecosystem. Recently, on September 12, 2023, Google announced a security issue in Google Chrome, titled "Heap buffer overflow in WebP in Google Chrome," which caught our attention. Initially, it seemed like just another bug in the popular web browser. However, what we discovered was far more significant and had implications that extended well beyond Chrome.

Recently, Qualys discovered and reported a critical vulnerability affecting the popular GLIBC ecosystem, which is installed by default on most Linux-based operating systems. Specifically, a buffer overflow was found in the code responsible for handling special environment variables during the startup of a process which can result in a local privilege escalation. Fortunately, exploitation of this vulnerability can be detected by Falco.

The developer role is steadily expanding, now encompassing operations and security functions in addition to writing and testing code.

Last month, two Critical vulnerabilities (CVE-2023-4863 and CVE-2023-5129) were identified by Apple Security Engineering and Architecture (SEA) in collaboration with The Citizen Lab at the University of Toronto’s Munk School. The vulnerabilities involved maliciously formed WebP images that would exploit Chromium-based browsers and the webmproject/libwebp library provided by Google. You can learn more about the vulnerability and the recent history of it in our previous blog post.

The cloud revolution has firmly taken hold, and businesses of all sizes are adopting cloud-native technologies. This new paradigm has also created newer attack surfaces for cybercriminals, who are eager to exploit known security gaps in cloud environments. Sysdig is collaborating with Docker to deliver a more efficient process for identifying risks and opportunities for accelerated remediation in Docker Scout using runtime insights.

In the tech security scene, we’re always on the lookout for new vulnerabilities, especially when they are already exploited in the wild. The latest zero-day CVE-2023-20269 is hitting Cisco’s Adaptive Security Appliance VPN features. The attack surface scan conducted by IONIX research on a sample of organizations indicates that 13% of these appliances are potentially vulnerable through at least one interface.
