An authentication and authorization bypass vulnerability exists in F5 NGINX Kubernetes Ingress Controller (NIC) when configured with the `ExternalAuth` policy or Ingress external authentication. Client-supplied X-Forwarded-Prefix, X-Forwarded-URI, X-Original-URI, and X-Forwarded-Method routing and method headers are forwarded unsanitized into the internal authentication subrequest (handled by the NGINX auth_request directive). As a result, an unauthenticated, remote attacker may spoof request attributes evaluated by the external authentication provider. <\/p>\n
Impact:
\nThis vulnerability may allow remote attackers <\/p>\n
unauthenticated<\/p>\n
access to protected <\/p>\n
paths. There is no control plane exposure; this is a data plane issue only.<\/p>\n
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.<\/p>\n","protected":false},"excerpt":{"rendered":"
