Short explanation
The Trainer v2 TrainJob API permits a user to inject valueFrom.secretKeyRef into environment variable definitions, allowing reading and exfiltration of namespace secrets and leading to privilege escalation (S0).
An attacker with limited permissions can steal secrets and achieve privilege escalation within OpenShift AI, increasing the risk of data breach and further compromise (S0).
What should be done?
- Restrict TrainJob creation permissions (S0)
- Review and tighten RBAC to limit Secret read access (S0)
- Monitor for suspicious env variable definitions (S0)
- Follow Red Hat security guidance (S0)
- Apply patches when vendor releases them (S0)
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.
Chain of evidence and sources
Trainer v2 TrainJob API’sı, valueFrom.secretKeyRef enjeksiyonuna izin vererek gizli anahtarların dışa aktarılmasını mümkün kılar (S0).
Bu açık, TrainJob oluşturma izni ve TrainJob RBAC’sının Secret okuma RBAC’sından daha geniş olması koşuluyla gerçekleşir (S0).
Yama durumu resmi kaynaklarda doğrulanamadı; yama yok anlamına gelmez (S0).
Show the technical text from the sources
A flaw was found in the Trainer v2 TrainJob API. A user with permissions to create TrainJobs can exploit this by injecting `valueFrom.secretKeyRef` into environment variable definitions. This allows them to read and exfiltrate sensitive information (secrets) from the namespace, leading to a privilege escalation. This occurs when the TrainJob Role-Based Access Control (RBAC) is broader than the Secret read RBAC.
