Описание
A flaw was found in the MaaS API. This vulnerability allows any pod within the cluster to bypass the Kuadrant AuthPolicy gateway by forging HTTP headers, specifically X-MaaS-Username and X-MaaS-Group, which are trusted verbatim. This lack of first-party authentication enables an attacker to gain unauthorized access and escalate privileges. The concrete consequences include the ability to mint Kubernetes ServiceAccount tokens in other tenants' namespaces, revoke API keys, and exfiltrate sensitive model access configuration.
Отчет
This is an Important flaw in the MaaS API, enabling privilege escalation due to a lack of first-party authentication. The API trusts X-MaaS-Username and X-MaaS-Group HTTP headers verbatim, allowing any pod within the cluster to bypass the Kuadrant AuthPolicy gateway and forge requests. This can lead to unauthorized access to Kubernetes ServiceAccount tokens and sensitive configuration data across tenants.
