Assigner: Kubernetes

Description
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.)

Executive Summary

CVE-2025-1097 is a security vulnerability identified in the ingress-nginx controller, specifically related to the `auth-tls-match-cn` annotation. This issue allows for configuration injection, which can lead to arbitrary code execution within the context of the ingress-nginx controller and the potential disclosure of Secrets that the controller can access. [1]

Detection Guidance

Users can verify if they are affected by checking for the ingress-nginx installation in their cluster using the command `kubectl get pods --all-namespaces --selector app.kubernetes.io/name=ingress-nginx`. Detection of suspicious data within the `auth-tls-match-cn` annotation of an Ingress resource may indicate an attempt to exploit this vulnerability. [1]

Impact Analysis

The vulnerability can lead to arbitrary code execution in the context of the ingress-nginx controller, which may allow an attacker to execute malicious code and access sensitive Secrets that the controller can access. [1]

Mitigation Strategies

To mitigate this vulnerability, it is essential to upgrade ingress-nginx to at least v1.11.5 or v1.12.1, or any later version. [1]
