How to mitigate kubelet's CVE-2021-25741: Symlink exchange can allow host filesystem access

CVE-2021-25741 is a new vulnerability discovered in Kubernetes that allows users to create a container with subpath volume mounts to access files & directories outside of the volume, including the host filesystem. It was disclosed in September 2021 and affects kubelet, which is the node agent that runs on each Kubernetes node. In particular CVE-2021-25741 affects kubelet in these Kubernetes versions.

OWASP Top 10 2021 is out - what's new and changed

It doesn’t seem that long ago that I wrote about the OWASP Top 10 changes that came in 2017. OWASP has announced the release for the new 2021 Top 10. Find out more about Broken Access Control and Cryptographic Failure vulnerabilities and understand what it means for application development and DevSecOps

OWASP Top 10 2021 Released

The Open Web Application Security Project (OWASP) is a not-for-profit organisation that aims, through community-led open-source projects, to improve the security of web-based software. OWASP develop and manage a public framework that documents the top 10 risks to application security, the OWASP Top 10. It provides developers and security professionals with the industry’s consensus on the most significant risks to web applications and recommends security controls to mitigate them.

The 2021 OWASP Top 10

The Open Web Application Security Project (OWASP), founded by Mark Curphey, first released the OWASP Top 10 Web Application Security Risks in 2003. The Top 10 is the closest the development community has to a set of commandments on how to build secure applications. This list represents the most critical risks to software security today and is recognized by developers as the first step toward creating more secure code.

Head-to-Head: Penetration Testing vs. Vulnerability Scanning

To release reasonably secure products, vendors must integrate software security processes throughout all stages of the software development lifecycle. That would include product architecture and design; implementation and verification; deployment and monitoring in the field; and back again to design to address the changing threat landscape, market needs, and product issues.

Use Kubescape to check if your Kubernetes clusters are exposed to the latest K8s Symlink vulnerability (CVE-2021-25741)

A new HIGH severity vulnerability was found in Kubernetes in which users may be able to create a container with subpath volume mounts to access files & directories outside of the volume, including on the host filesystem. The issue is affecting the Kubelet component of Kubernetes (Kubelet is the primary "node agent" that runs on each node. It registers the node with the apiserver and launches PODs on it).

Apple's Vulnerability

Apple has issued an emergency software update after a cyber-surveillance company created invasive spyware that could infect any iPhone, iPad, Apple Watch, or Mac Computer. Toronto-based internet watchdog security group Citizen Lab said that NSO, the surveillance company which is an Israeli spyware company, developed the tool with a technique that could easily exploit Apple software.

Supply Chain Security Update: How Secure is Composer?

When it comes to PHP, composer is without discussion, THE package manager. It’s fast, easy to use, actively maintained and very secure — or so most thought. On April 21, 2021, a command injection vulnerability was reported, which shook the PHP community. Fortunately it didn’t have a very big impact, but it could have. The problem with the vulnerability is that it affected the very heart of the Composer supply chain: Packagist servers.

Missing Critical Vulnerabilities Through Narrow Scoping

The typical process when scoping a penetration test is to get a list of targets from the client, which are typically a list of IP addresses and/or hostnames. But where does this information come from, and how accurate is it? Chances are the client has documentation that lists the devices they think they have, and what addresses or names they have been assigned. This documentation will form the basis of the scope when conducting testing or scanning against a target environment.

What is a Network Vulnerability Assessment?

A network vulnerability assessment is the reviewing and analyzing of an organization’s network infrastructure to find cybersecurity vulnerabilities and network security loopholes. The assessment can be carried out either manually or by using vulnerability analysis software — although the latter is preferred because it’s less susceptible to human error and usually delivers more accurate results.

A guide to OWASP's secure coding

Modern organizations rely heavily on software and systems. Secure coding standards are significant, as they give some assurance that software installed on the organization’s system is protected from security flaws. These security standards, when used correctly, can avoid, identify, and remove loopholes that might jeopardize software integrity. Furthermore, whether developing software for portable gadgets, desktop systems, or servers, secure coding is critical for modern software development.

Detect and prevent dependency confusion attacks on npm to maintain supply chain security

On February 9, 2021, Alex Birsan disclosed his aptly named security research, dependency confusion. In his disclosure, he describes how a novel supply chain attack that exploits misconfiguration by developers, as well as design flaws of numerous package managers in the open source language-based software ecosystems, allowed him to gain access and exfiltrate data from companies such as Yelp, Tesla, Apple, Microsoft, and others.

Tips for Patching Security Vulnerabilities

Given the countless cyber threats facing organizations these days, security has become one of the most pressing issues on the executive mind. Yet when we talk about cybersecurity, we rarely focus on security vulnerabilities and how patching those vulnerabilities is crucial for a cybersecurity program. So what is vulnerability patching, exactly? A vulnerability is a flaw that cybercriminals can exploit to gain unauthorized access or to perform unauthorized actions on a computer system.

Critical Vulnerability in HAProxy (CVE-2021-40346): Integer Overflow Enables HTTP Smuggling

JFrog Security research teams are constantly looking for new and previously unknown vulnerabilities in popular open-source projects to help improve their security posture. As part of this effort, we recently discovered a potentially critical vulnerability in HAProxy, a widely used open-source load balancer proxy server that is particularly suited for very high traffic web sites and used by many leading companies.

Risk Mitigation Strategies for Tcp/IP Vulnerabilities in OT

JFrog in collaboration with Forescout Research Labs recently released the fourth study from Project Memoria - the industry’s most comprehensive study of TCP/IP vulnerabilities. INFRA:HALT covers 14 vulnerabilities affecting the popular closed source TCP/IP stack NicheStack. These vulnerabilities can cause Denial of Service or Remote Code Execution, allowing attackers to take targeted OT and ICS devices offline or take control of them.

Why is AT&T adding Web Application Shielding to its Managed Vulnerability Program?

Cybercriminals never sleep. Why? They're too busy looking for application vulnerabilities. In the world of cybercrime, a flawed application is a potential goldmine for them, but an onramp to disaster for most organizations.
