CyberRota Analysis
AI-GeneratedKubernetes versions prior to 1.6.6 and from 1.7.0 to 1.7.3 are vulnerable due to a flaw in the SAML authentication process, allowing attackers to exploit concurrent requests with the same SAML session token. This can lead to unauthorized access to SAML-protected gRPC endpoints, enabling attackers to create persistent credentials and generate audit entries under the victim's identity, thereby compromising confidentiality, integrity, and availability based on the victim's privileges. Organizations using affected Kubernetes versions should prioritize upgrading to the patched versions to mitigate this high-severity vulnerability.

Original NVD Description
Omni manages Kubernetes on bare metal, virtual machines, or in a cloud. Prior to 1.6.6 and from 1.7.0 until 1.7.3, SAML.getSession in internal/pkg/auth/interceptor/saml.go checks SAMLAssertion.Used and marks it used in separate state operations. Concurrent requests carrying the same captured saml-session token can each observe the assertion as unused and obtain authentication as the victim before either update is visible. The attacker can invoke SAML-protected gRPC endpoints, use ConfirmPublicKey to create multiple persistent credentials tied to the victim, and generate audit entries attributed to the victim, with the resulting access potentially affecting confidentiality, integrity, and availability according to the victim's privileges. This issue is fixed in versions 1.6.6 and 1.7.3.
