"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.");
