Описание
A flaw was found in the skupper console, a read-only interface that renders cluster network, traffic details, and metrics for a network application that a user sets up across a hybrid multi-cloud environment. When the default authentication method is used, a random password is generated for the "admin" user and is persisted in either a Kubernetes secret or a podman volume in a plaintext file. This authentication method can be manipulated by an attacker, leading to the reading of any user-readable file in the container filesystem, directly impacting data confidentiality. Additionally, the attacker may induce skupper to read extremely large files into memory, resulting in resource exhaustion and a denial of service attack.
Отчет
This vulnerability is rated as an Important severity due to the risk of data confidentiality breaches and potential denial-of-service attacks where attackers can manipulate the default authentication method to access sensitive files and exhaust system resources by reading large files, affecting both data integrity and service availability in hybrid multi-cloud environments.
Меры по смягчению последствий
For users running skupper on Red Hat OpenShift, the OpenShift authentication should be used. Otherwise, use "unsecured" where authentication is not a primary concern.
