Publication Date:	2025-04-08
Last Update:	2025-04-08
Current Version:	V1.0
CVSS v3.1 Base Score:	9.8

SUMMARY

Insights Hub Private Cloud is affected by multiple vulnerabilities in Ingress NGINX Controller for Kubernetes. These vulnerabilities could lead to arbitrary code execution in the context of the ingress-nginx controller, or disclosure of Secrets accessible to the controller, or denial of service condition.

Siemens has released a new version for Insights Hub Private Cloud and recommends to update to the latest version.

GENERAL SECURITY RECOMMENDATIONS

As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals.

VULNERABILITY DESCRIPTION

Un-/Collapse All

This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.

Vulnerability CVE-2025-1097

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.)

CVSS v3.1 Base Score	8.8
CVSS v3.1 Vector	CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CWE	CWE-20: Improper Input Validation

Vulnerability CVE-2025-1098

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.)

CVSS v3.1 Base Score	8.8
CVSS v3.1 Vector	CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CWE	CWE-20: Improper Input Validation

Vulnerability CVE-2025-1974

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.)

CVSS v3.1 Base Score	9.8
CVSS v3.1 Vector	CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE	CWE-653: Improper Isolation or Compartmentalization

Vulnerability CVE-2025-24513

A security issue was discovered in ingress-nginx https://github.com/kubernetes/ingress-nginx where attacker-provided data are included in a filename by the ingress-nginx Admission Controller feature, resulting in directory traversal within the container. This could result in denial of service, or when combined with other vulnerabilities, limited disclosure of Secret objects from the cluster.

CVSS v3.1 Base Score	4.8
CVSS v3.1 Vector	CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:L
CWE	CWE-20: Improper Input Validation

Vulnerability CVE-2025-24514

A security issue was discovered in ingress-nginx https://github.com/kubernetes/ingress-nginx where the auth-url 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.)
