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 Master Data Management, versions - 710, 710.750, allows a malicious unauthorized user with access to the MDM Server subnet to find the password using a brute force method. If successful, the attacker could obtain access to highly sensitive data and MDM administrative privileges leading to information disclosure vulnerability thereby affecting the confidentiality and integrity of the application. This happens when security guidelines and recommendations concerning administrative accounts of an SAP NetWeaver Master Data Management installation have not been thoroughly reviewed.

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 · high confidence

SAP NetWeaver Master Data Management versions 710 and 710.750 contains a vulnerability allowing an unauthorized user with network access to the MDM Server subnet to perform brute force attacks against administrative accounts. Successful exploitation grants access to highly sensitive data and MDM administrative privileges, resulting in information disclosure and privilege escalation.

MitigationImplement account lockout policies and enforce strong password policies for administrative accounts following SAP security guidelines. Restrict network access to the MDM Server subnet and consider implementing multi-factor authentication for administrative access.

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 if SAP NetWeaver MDM is running
    Check running processes or services for SAP MDM components, or query the SAP system for installed products using SAP transaction SE84 or SM37 for MDM-related jobs
    Affected if SAP NetWeaver Master Data Management software is installed and running
  2. Determine the installed MDM version
    Access SAP MDM administrative console or check installed product version via SAP transaction SM51, or inspect SAP MDMWIZARD configuration files if accessible
    Affected if The version is 7.10, 7.10.750, or 710 (exact match to affected versions)
  3. Verify network accessibility of MDM Server
    Identify open ports typically used by MDM (like 50000-50004 for RFC/HTTP) and test connectivity from external/untrusted networks using tools like telnet, nmap, or netcat
    Affected if The MDM Server ports are reachable from networks outside the trusted MDM Server subnet without authentication barriers
  4. Confirm administrative accounts exist
    Review MDM user administration settings via SAP transaction SU01 or MDM Console user management to verify administrative accounts are configured
    Affected if Administrative accounts are present in the MDM system (prerequisite for brute force target)
  5. Check for account lockout policy enforcement
    Review MDM security configuration or SAP profile parameters for failed login lockout settings using transaction RZ10 or security audit logs
    Affected if No account lockout policy is configured or enforced for MDM administrative accounts

A user is affected if they run SAP NetWeaver MDM versions 7.10 or 7.10.750 with the server accessible from an unauthorized network and without account lockout protections in place.
