RunC Flaws Enable Container Escapes, Granting Attackers Host Access

RunC Flaws Enable Container Escapes, Granting Attackers Host Access

Jan 31, 2024 Software Security / Linux
Multiple security vulnerabilities have been disclosed in the runC command line tool that could be exploited by threat actors to escape the bounds of the container and stage follow-on attacks. The vulnerabilities, tracked as CVE-2024-21626, CVE-2024-23651, CVE-2024-23652, and CVE-2024-23653, have been collectively dubbed  Leaky Vessels  by cybersecurity vendor Snyk. "These container escapes could allow an attacker to gain unauthorized access to the underlying host operating system from within the container and potentially permit access to sensitive data (credentials, customer info, etc.), and launch further attacks, especially when the access gained includes superuser privileges," the company  said  in a report shared with The Hacker News. runC  is a tool for spawning and running containers on Linux. It was originally developed as part of Docker and later  spun out  into a separate open-source library in 2015. A brief description of each of the flaws is below - CVE-202

Alert: New Kubernetes Vulnerabilities Enable Remote Attacks on Windows Endpoints

Sep 13, 2023 Kubernetes / Cloud Security
Three interrelated high-severity security flaws discovered in Kubernetes could be exploited to achieve remote code execution with elevated privileges on Windows endpoints within a cluster. The  issues , tracked as CVE-2023-3676, CVE-2023-3893, and CVE-2023-3955, carry CVSS scores of 8.8 and impact all Kubernetes environments with Windows nodes. Fixes for the vulnerabilities were  released  on August 23, 2023, following responsible disclosure by Akamai on July 13, 2023. "The vulnerability allows remote code execution with SYSTEM privileges on all Windows endpoints within a Kubernetes cluster," Akamai security researcher Tomer Peled said in a technical write-up shared with The Hacker News. "To exploit this vulnerability, the attacker needs to apply a malicious YAML file on the cluster." Amazon Web Services  (AWS),  Google Cloud , and  Microsoft Azure  have all released advisories for the bugs, which affect the following versions of Kubelet - kubelet < v1.28

Auditing Kubernetes with Open Source SIEM and XDR

Feb 01, 2023 SIEM / Kubernetes
Container technology has gained traction among businesses due to the increased efficiency it provides. In this regard, organizations widely use Kubernetes for deploying, scaling, and managing containerized applications. Organizations should audit Kubernetes to ensure compliance with regulations, find anomalies, and identify security risks. The Wazuh open source platform plays a critical role in monitoring Kubernetes and other components of an organization's infrastructure. What is Kubernetes? Kubernetes is an open source container management solution that automates the deployment and scaling of containers and also manages the life cycle of containers. It organizes containers into logical units for simple management and discovery. Kubernetes extends how we scale containerized applications so that we may use a truly persistent infrastructure. You can build cloud-native applications based on microservices with Kubernetes. Enthusiasts view Kubernetes as the cornerstone of application m

Yes, Containers Are Terrific, But Watch the Security Risks

Yes, Containers Are Terrific, But Watch the Security Risks

May 23, 2022
Containers revolutionized the development process, acting as a cornerstone for DevOps initiatives, but containers bring complex security risks that are not always obvious. Organizations that don't mitigate these risks are vulnerable to attack.  In this article, we outline how containers contributed to agile development, which unique security risks containers bring into the picture – and what organizations can do to secure containerized workloads, going beyond DevOps to achieve  DevSecOps . Why did containers catch on so fast? Containers are, in many ways, the evolution of virtualization. The goal was to speed up the development process, creating a more agile route from development through to testing and implementation – a method that's more lightweight than using full-blown virtual machines, anyway. At the core of this issue is application compatibility, as applications require certain versions of libraries – which could clash with the requirements of other applications. Container
New Vulnerability in CRI-O Engine Lets Attackers Escape Kubernetes Containers

New Vulnerability in CRI-O Engine Lets Attackers Escape Kubernetes Containers

Mar 17, 2022
A newly disclosed security vulnerability in the Kubernetes container engine CRI-O called  cr8escape  could be exploited by an attacker to break out of containers and obtain root access to the host. "Invocation of CVE-2022-0811 can allow an attacker to perform a variety of actions on objectives, including execution of malware, exfiltration of data, and lateral movement across pods," CrowdStrike researchers John Walker and Manoj Ahuje  said  in an analysis published this week. A lightweight alternative to Docker,  CRI-O  is a  container runtime  implementation of the Kubernetes Container Runtime Interface (CRI) that's used to pull container images from registries and launch an Open Container Initiative ( OCI )-compatible runtime such as runC to spawn and run container processes. The vulnerability is rated 8.8 on the CVSS vulnerability scoring system and affects CRI-O versions 1.19 and later. Following responsible disclosure, patches have been released to address the fl
