Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.23% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Dell Container Storage Modules and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

What, why and how

Dell Container Storage Modules, versions prior to 1.18.0, contain(s) a Missing Authorization vulnerability in the Dell CSI Driver for PowerMax - csireverseproxy . An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Unauthorized access.

What

Dell Container Storage Modules, versions prior to 1.18.0, contain(s) a Missing Authorization vulnerability in the Dell CSI Driver for PowerMax - csireverseproxy . An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Unauthorized access.

Why

The application reaches a protected operation without first confirming that the requester is authorised.

How

An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
an adjacent network → Missing Authorization → cause the confidentiality, integrity or availability impact described by the vendor

Privileges required

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-862 ↗

CWE-862: Missing Authorization. The product does not perform an authorization check when an actor attempts to access a resource or perform an action.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

Official EUVD record ↗
NCSC-NL · Dutch · NCSC-2026-0400Dell heeft kwetsbaarheden verholpen in Container storage modules

De kwetsbaarheden bevinden zich in Dell Container Storage Modules (CSM), die worden gebruikt voor de integratie van Dell-opslagsystemen met containerplatformen zoals Kubernetes en OpenShift. De geïdentificeerde kwetsbaarheden omvatten onder meer authenticatie- en autorisatiebypasses, privilege-escalatie, informatielekken en kwetsbaarheden in CSM-componenten en CSI-drivers. Afhankelijk van de specifieke kwetsbaarheid en de netwerkpositie en privileges van de aanvaller, kunnen aanvallers zonder authenticatie of met beperkte rechten onder andere administratieve toegang tot CSM verkrijgen, gevoelige informatie zoals Kubernetes Secrets uitlezen, RBAC-configuraties manipuleren en in het geval van bepaalde kwetsbaarheden root-level toegang tot Kubernetes-clusternodes verkrijgen. In de meest ernstige gevallen kan hierdoor de volledige CSM-omgeving en de gekoppelde storage-infrastructuur worden gecompromitteerd. Misbruik van de kwetsbaarheden kan daarmee leiden tot een aantasting van de vertrouwelijkheid, integriteit en beschikbaarheid van getroffen Kubernetes-/OpenShift-omgevingen en de daaraan gekoppelde Dell-opslaginfrastructuur.
