Ingress-NGINX controller < 1.11.5 / 1.12 < 1.12.1 Multiple Vulnerabilities

critical Nessus Plugin ID 233357

Language:

Synopsis

The remote host is missing one or more security updates.

Description

The version of Ingres-NGINX controller installed on the remote host is prior to 1.11.5/1.12.1. It is, therefore, affected by multiple vulnerabilities as referenced as Ingress Nightmare.

 - A security issue was discovered in Kubernetes where under certain conditions, an unauthenticated attacker with access to the pod network can achieve arbitrary code execution in the context of the ingress-nginx controller. This can lead to disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.) (CVE-2025-1974)

 - A security issue was discovered in ingress-nginx https://github.com/kubernetes/ingress-nginx where the `mirror-target` and `mirror-host` Ingress annotations can be used to inject arbitrary 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.) (CVE-2025-1098)
- A security issue was discovered in ingress-nginx https://github.com/kubernetes/ingress-nginx where the `auth-tls-match-cn` 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.) (CVE-2025-1097)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Ingress-nginx Controller 1.11.5/1.12.1.
