CVE-2025-1098 Siemens CVE debrief

Who should care

Operators of Siemens Insights Hub Private Cloud, Kubernetes platform teams, and administrators responsible for ingress-nginx deployments and Ingress resource governance.

Technical summary

The supplied CISA/Siemens material identifies Siemens Insights Hub Private Cloud as the affected product and attributes the issue to ingress-nginx annotation handling. Specifically, the mirror-target and mirror-host Ingress annotations can be used to inject arbitrary configuration into nginx. The documented consequences are code execution in the controller context and exposure of Secrets available to the ingress-nginx controller. The remediation listed in the advisory is to contact customer support for patch and update information.

Defensive priority

High

Recommended defensive actions

• Contact Siemens customer support for patch and update guidance for Insights Hub Private Cloud.
• Inventory deployments to confirm whether ingress-nginx is part of the affected stack.
• Review who can create or modify Ingress resources and restrict annotation usage to trusted administrators.
• Treat Secrets accessible to the ingress-nginx controller as potentially exposed until patches are applied and exposure is ruled out.
• Monitor ingress-nginx controller and nginx configuration changes for unexpected annotation-driven changes.
• If exposure is suspected, rotate credentials and Secrets reachable by the controller.

Evidence notes

This debrief is based only on the supplied CISA CSAF source item for ICSA-25-100-05, which cites Siemens advisory SSA-817234, and on the supplied CVE metadata. The source corpus names Siemens Insights Hub Private Cloud as the affected product and states that ingress-nginx mirror-target and mirror-host annotations can inject arbitrary nginx configuration, leading to controller-context code execution and Secret disclosure. The supplied data does not provide fixed affected version ranges or exploitation-in-the-wild details. The enrichment data also shows no KEV listing.
