A critical security flaw has been disclosed in the NVIDIA Container Toolkit that, if successfully exploited, could allow threat actors to break out of the confines of a container and gain full access to the underlying host. The vulnerability, tracked as CVE-2024-0132 , carries a CVSS score of 9.0 out of a maximum of 10.0. It has been addressed in NVIDIA Container Toolkit version v1.16.2 and NVIDIA GPU Operator version 24.6.2. "NVIDIA Container Toolkit 1.16.1 or earlier contains a Time-of-Check Time-of-Use ( TOCTOU ) vulnerability when used with default configuration where a specifically crafted container image may gain access to the host file system," NVIDIA said in an advisory. "A successful exploit of this vulnerability may lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering." The issue impacts all versions of NVIDIA Container Toolkit up to and including v1.16.1, and Nvidia GPU Operator up to and i...

Cybersecurity researchers have disclosed a security flaw impacting Microsoft Azure Kubernetes Services that, if successfully exploited, could allow an attacker to escalate their privileges and access credentials for services used by the cluster. "An attacker with command execution in a pod running within an affected Azure Kubernetes Services cluster could download the configuration used to provision the cluster node, extract the transport layer security (TLS) bootstrap tokens, and perform a TLS bootstrap attack to read all secrets within the cluster," Google-owned Mandiant said . Clusters using "Azure CNI" for the "Network configuration" and "Azure" for the "Network Policy" have been found to be impacted by the privilege escalation bug. Microsoft has since addressed the issue following responsible disclosure. The attack technique devised by the threat intelligence firm hinges on accessing a little-known component called Azure WireS...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Docker is warning of a critical flaw impacting certain versions of Docker Engine that could allow an attacker to sidestep authorization plugins (AuthZ) under specific circumstances. Tracked as CVE-2024-41110 , the bypass and privilege escalation vulnerability carries a CVSS score of 10.0, indicating maximum severity. "An attacker could exploit a bypass using an API request with Content-Length set to 0, causing the Docker daemon to forward the request without the body to the AuthZ plugin, which might approve the request incorrectly," the Moby Project maintainers said in an advisory. Docker said the issue is a regression in that the issue was originally discovered in 2018 and addressed in Docker Engine v18.09.1 in January 2019, but never got carried over to subsequent versions (19.03 and later). The issue has been resolved in versions 23.0.14 and 27.1.0 as of July 23, 2024, after the problem was identified in April 2024. The following versions of Docker Engine are impacte...

Cybersecurity researchers have warned of an ongoing cryptojacking campaign targeting misconfigured Kubernetes clusters to mine Dero cryptocurrency. Cloud security firm Wiz, which shed light on the activity, said it's an updated variant of a financially motivated operation that was first documented by CrowdStrike in March 2023. "In this incident, the threat actor abused anonymous access to an Internet-facing cluster to launch malicious container images hosted at Docker Hub, some of which have more than 10,000 pulls," Wiz researchers Avigayil Mechtinger, Shay Berkovich, and Gili Tikochinski said . "These docker images contain a UPX-packed DERO miner named 'pause.'" Initial access is accomplished by targeting externally accessible Kubernetes API servers with anonymous authentication enabled to deliver the miner payloads. Unlike the 2023 version that deployed a Kubernetes DaemonSet named "proxy-api," the latest flavor makes use of seemingly b...

Threat actors are actively exploiting critical vulnerabilities in OpenMetadata to gain unauthorized access to Kubernetes workloads and leverage them for cryptocurrency mining activity. That's according to the Microsoft Threat Intelligence team, which  said  the flaws have been weaponized since the start of April 2024. OpenMetadata is an  open-source platform  that operates as a metadata management tool, offering a unified solution for data asset discovery, observability, and governance. The flaws in question – all discovered and credited to security researcher Alvaro Muñoz – are listed below - CVE-2024-28847  (CVSS score: 8.8) - A Spring Expression Language (SpEL) injection vulnerability in PUT /api/v1/events/subscriptions (fixed in version 1.2.4) CVE-2024-28848  (CVSS score: 8.8) - A SpEL injection vulnerability in GET /api/v1/policies/validation/condition/<expr> (fixed in version 1.2.4) CVE-2024-28253  (CVSS score: 8.8) - A SpEL injecti...

Details have been made public about a now-patched high-severity flaw in Kubernetes that could allow a malicious attacker to achieve remote code execution with elevated privileges under specific circumstances. "The vulnerability allows remote code execution with SYSTEM privileges on all Windows endpoints within a Kubernetes cluster," Akamai security researcher Tomer Peled  said . "To exploit this vulnerability, the attacker needs to apply malicious YAML files on the cluster." Tracked as CVE-2023-5528 (CVSS score: 7.2), the shortcoming impacts all versions of kubelet, including and after version 1.8.0. It was addressed as part of updates released on November 14, 2023, in the following versions - kubelet v1.28.4 kubelet v1.27.8 kubelet v1.26.11, and kubelet v1.25.16 "A security issue was discovered in Kubernetes where a user that can create pods and persistent volumes on Windows nodes may be able to escalate to admin privileges on those nodes," Kubernetes maintainers  s...

Google Cloud has addressed a medium-severity security flaw in its platform that could be abused by an attacker who already has access to a Kubernetes cluster to escalate their privileges. "An attacker who has compromised the  Fluent Bit  logging container could combine that access with high privileges required by  Anthos Service Mesh  (on clusters that have enabled it) to escalate privileges in the cluster," the company  said  as part of an advisory released on December 14, 2023. Palo Alto Networks Unit 42, which discovered and reported the shortcoming, said adversaries could weaponize it to carry out "data theft, deploy malicious pods, and disrupt the cluster's operations." There is no evidence that the issue has been exploited in the wild. It has been addressed in the following versions of Google Kubernetes Engine (GKE) and Anthos Service Mesh (ASM) - 1.25.16-gke.1020000 1.26.10-gke.1235000 1.27.7-gke.1293000 1.28.4-gke.1083000 1.17.8-asm.8 ...

Cybersecurity researchers are warning of publicly exposed Kubernetes configuration secrets that could put organizations at risk of supply chain attacks. "These encoded Kubernetes configuration secrets were uploaded to public repositories," Aqua security researchers Yakir Kadkoda and Assaf Morag  said  in a new research published earlier this week. Some of those impacted include two top blockchain companies and various other fortune-500 companies, according to the cloud security firm, which leveraged the GitHub API to fetch all entries containing .dockerconfigjson and .dockercfg types that  store credentials  for accessing a container image registry. Of the 438 records that potentially held valid credentials for registries, 203 records – about 46% – contained valid credentials that provided access to the respective registries. Ninety-three of the passwords were manually set by individuals, as opposed to the 345 that were computer-generated. "In the majority of ...
