Executive Summary

This vulnerability exists in MARIN3R versions 0.13.3 and below, where the DiscoveryServiceCertificate component allows users to bypass Role-Based Access Control (RBAC) and access secrets in namespaces they are not authorized to access. Essentially, it is a cross-namespace secret access vulnerability that lets unauthorized users retrieve sensitive information from other namespaces.

Impact Analysis

The vulnerability can lead to unauthorized access to sensitive secrets across different namespaces in a Kubernetes environment. This can result in exposure of confidential data, potential privilege escalation, and compromise of the security boundaries intended by RBAC policies, thereby increasing the risk of data breaches and system compromise.

Mitigation Strategies

Upgrade MARIN3R to version 0.13.4 or later, as this version fixes the cross-namespace secret access vulnerability in the DiscoveryServiceCertificate component.
