ingress-nginx controller - configuration injection via unsanitized auth-url annotation
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Go | k8s.io/ingress-nginx | < 1.11.5 | 1.11.5 |
| Go | k8s.io/ingress-nginx | >= 1.12.0-beta.0, < 1.12.1 | 1.12.1 |
Details
As written in the advisory (Markdown source, shown as plain text).
A security issue was discovered in [ingress-nginx](https://github.com/kubernetes/ingress-nginx) where the `auth-url` Ingress annotation can be used to inject configuration into nginx. This can lead to arbitrary code execution in the context of the ingress-nginx controller, and disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)
