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
Certain vulnerable endpoints in SAP NetWeaver AS Java (Heap Dump Application), versions 7.30, 7.31, 7.40, 7.50, provide valuable information about the system like hostname, server node and installation path that could be misused by an attacker leading to Information Disclosure.

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 AS Java Heap Dump Application contains vulnerable endpoints that expose sensitive system information including hostname, server node, and installation path. This information disclosure could aid attackers in reconnaissance and planning further attacks against the system.

MitigationRestrict access to the Heap Dump Application endpoints through network segmentation or authentication controls, and apply available SAP security patches for this vulnerability.

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 the SAP NetWeaver AS Java installation
    Query the SAP system for product information using transaction code SM51 or check the SAP system landscape directory for installed components matching SAP NetWeaver Application Server Java
    Affected if The system is running SAP NetWeaver AS Java component
  2. Check the installed NetWeaver Java version
    Retrieve the SAP NetWeaver version from the system using SM51, SARFC or by checking the installed software component versions in the system; compare against affected versions 7.30, 7.31, 7.40, and 7.50
    Affected if The installed version matches exactly 7.30, 7.31, 7.40, or 7.50
  3. Locate the Heap Dump Application
    Identify if the Heap Dump Application (HeapDump) is deployed on the SAP Java system by checking the web dispatcher configuration or the ICM (Internet Communication Manager) ports for paths typically under /HeapDump or similar heap dump endpoints
    Affected if The Heap Dump application is deployed and accessible via web ports
  4. Test for sensitive information disclosure
    Attempt to access the Heap Dump endpoints (such as /HeapDump) over HTTP/HTTPS and verify if the response contains system details including hostname, server node name, or installation file paths
    Affected if The endpoint returns sensitive system information including hostname, server node, or installation path

A system is affected if it runs SAP NetWeaver AS Java versions 7.30, 7.31, 7.40, or 7.50 AND has the Heap Dump Application accessible, allowing unauthenticated retrieval of system reconnaissance data.
