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 System Configuration does not perform necessary authorization checks for an authenticated user, resulting in escalation of privileges. This could completely compromise the integrity and availability with no impact on confidentiality of the 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 System Configuration contains an authorization bypass vulnerability where authenticated users can perform privileged actions without proper authorization checks, leading to privilege escalation. This allows authenticated attackers to compromise system integrity and availability while confidentiality remains unaffected.

MitigationImplement comprehensive authorization checks across all system configuration functions and enforce role-based access control (RBAC) to ensure users can only execute actions within their assigned privilege scope.

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. Identify SAP NetWeaver version
    Use transaction code SM51 to display the SAP NetWeaver release version, or check the kernel version via the SAP MMC or command 'disp+work -v' in the kernel directory
    Affected if The installed version falls within the affected NetWeaver release range for CVE-2025-42953 (compare your version against known affected releases)
  2. Locate System Configuration module
    Access the SAP System Configuration via transaction code SA38 or directly navigate to the System Configuration node in SAP GUI (transaction code SCC4 for client configuration, SCC1 for transport between clients)
    Affected if The System Configuration module is active and accessible to authenticated users in your environment
  3. Verify authorization role assignments
    Use transaction code PFCG to review role definitions, then transaction code SUIM to search for users assigned to privileged roles. Check if standard users have roles that grant System Configuration access
    Affected if Standard authenticated users have roles that include System Configuration privileges without proper segregation of duties
  4. Test authorization boundary for privileged actions
    Log in as a non-privileged user and attempt to access System Configuration functions (e.g., changing system parameters via transaction code RZ10, modifying profile parameters, or accessing transport administration via SE01). Observe whether the system denies unauthorized access
    Affected if Authenticated non-privileged users can execute System Configuration functions that should require elevated privileges
  5. Review audit logs for privileged actions
    Use transaction code SM37 or SAL to examine system logs and audit traces for System Configuration changes performed by standard users. Filter logs for transaction codes related to system configuration and parameter changes
    Affected if Audit logs show System Configuration changes made by users who should not have privileged access based on their assigned roles

You are affected if your SAP NetWeaver version contains the vulnerability AND the System Configuration module is accessible to authenticated users without proper authorization enforcement, allowing standard users to perform privileged actions.
