Critical IngressNightmare Vulnerabilities Found in Kubernetes Environments

Critical vulnerabilities, collectively termed "IngressNightmare," have been identified in the Ingress NGINX Controller of Kubernetes environments, potentially impacting over 40% of internet-facing clusters. These flaws allow remote, unauthenticated attackers to execute arbitrary commands, potentially taking full control of affected Kubernetes clusters. 

The vulnerabilities include CVE-2025-24514, CVE-2025-1097, and CVE-2025-1098, which enable attackers to inject custom NGINX configuration directives, such as routing rules and security settings. To achieve remote code execution, these flaws can be combined with CVE-2025-1974. This combination of vulnerabilities has been assigned a CVSS severity score of 9.8, highlighting its critical nature. 

Organizations utilizing Kubernetes with Ingress NGINX Controller are strongly advised to apply the patches released by Kubernetes maintainers promptly to mitigate these risks and protect their environments from potential exploitation.

OWASP SAMM Skills Framework Enhances Software Security Roles

The OWASP SAMM Skills Framework, introduced on February 9, 2025, is a new initiative donated by Siemens to enhance software security practices within organizations. This framework assigns specific responsibilities to SAMM (Software Assurance Maturity Model) streams, clarifying which roles are involved in advancing each stream. It provides guidance on the necessary skills and training for each role, aligning SAMM-related activities with appropriate stakeholders and their required competencies. This alignment helps organizations identify the right personnel and visualize shared responsibilities, ensuring a structured approach to secure product development. Implementing the OWASP SAMM Skills Framework involves several key steps. Organizations must first map responsibilities to roles, ensuring each task is assigned to the right individual. Next, they must evaluate and align stakeholders with specific SAMM streams, validating that those assigned understand and accept their roles in advanci...
