Description
A security issue was discovered in ingress-nginx where a combination of Ingress annotations 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.)
Affected configurations
• kubernetes nginx ingress controller (< 1.13.9)
• kubernetes nginx ingress controller (>= 1.14.0 < 1.14.5)
• kubernetes nginx ingress controller 1.15.0
