Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
SAP NetWeaver Enterprise Portal Administration is vulnerable when a privileged user can upload untrusted or malicious content which, when deserialized, could potentially lead to a compromise of confidentiality, integrity, and availability of the host system.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

SAP NetWeaver Enterprise Portal Administration contains an unsafe deserialization vulnerability where a privileged user can upload untrusted or malicious content. When this content is deserialized by the application, it can lead to remote code execution, compromising the confidentiality, integrity, and availability of the host system.

MitigationApply the relevant SAP security patch for CVE-2025-42964 and implement strict validation/controls on file uploads in the Enterprise Portal Administration interface to prevent untrusted content from being processed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm SAP NetWeaver Enterprise Portal installation
    Identify if the system runs SAP NetWeaver Enterprise Portal by checking for SAP processes (e.g., dispatcher, server processes) or by querying the SAPMMC snap-in, or by examining the installation directory structure for SAP Enterprise Portal components.
    Affected if The system is running any version of SAP NetWeaver Enterprise Portal without the security patch applied.
  2. Verify Administration interface is accessible
    Access the SAP Enterprise Portal Administration URL (typically /irj/portal or /admin) and confirm the Administration module is available and functional.
    Affected if The Administration interface is accessible and operational on the SAP Enterprise Portal.
  3. Check for file upload capability in Administration
    Navigate through the Administration interface and identify if there is any file upload, import, or content management feature that handles serialized objects or files.
    Affected if The Administration module includes file upload or content import functionality that processes uploaded data.
  4. Review privileged user access
    Identify if any user accounts with elevated privileges (e.g., Administrator, Portal Administrator) exist and have access to the Administration interface.
    Affected if Privileged user accounts exist and can access the Administration file upload features.
  5. Compare installed version to vendor guidance
    Query the SAP system for its version information using transaction code SM37 or by checking the SAP Support Portal for CVE-2025-42964 affected version ranges.
    Affected if The installed SAP NetWeaver Enterprise Portal version falls within the affected range and has not applied the relevant security patch.

A user is affected if their system runs unpatched SAP NetWeaver Enterprise Portal with the Administration interface and its file upload functionality accessible to privileged users.
