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 AS ABAP Business Server Pages Test Application IT00, versions 700, 701, 702, 730, 731, 740, 750, 751, 752, 753, 754, does not sufficiently encode user-controlled inputs, resulting in reflected Cross-Site Scripting (XSS) vulnerability.

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 AS ABAP Business Server Pages (BSP) Test Application IT00 fails to properly encode user-controlled input, allowing attackers to inject malicious scripts via reflected parameters. This reflected XSS vulnerability enables session hijacking, credential theft, or defacement when users click crafted links.

MitigationApply proper output encoding to all user-controlled inputs in the BSP application, using context-appropriate encoding (HTML encoding for HTML body, URL encoding for URL parameters). Consider implementing a centralized encoding library or using SAP's built-in security features.

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 ABAP version
    Check the SAP system version using transaction SM51 or the SAP kernel version display. Compare the installed version against the affected list: 700, 701, 702, 730, 731, 740, 750, 751, 752, 753, 754.
    Affected if The installed version matches one of the listed versions.
  2. Determine if BSP Test Application IT00 is deployed
    Access the BSP application via its URL path, typically under /sap/bc/bsp/sap/it00/ or similar. Use transaction SE80 or SICF to list active BSP applications and check if IT00 is present and active.
    Affected if The BSP Test Application IT00 is found and accessible in the system.
  3. Verify if the application accepts user-controlled URL parameters
    Access the IT00 application with test parameters in the URL (for example, adding ?param=test to the application URL). Observe whether the parameter value is reflected back in the response without encoding.
    Affected if URL parameters are reflected in the HTML response without proper encoding.
  4. Inspect browser response for unencoded script tags
    Send a crafted URL with a script tag payload (for example, ?name=<script>alert(1)</script>) to the IT00 application and inspect whether the script tag executes or appears unescaped in the page source.
    Affected if The response contains the raw script tag or executes JavaScript, indicating the XSS vulnerability is present.

A system is affected if it runs any of the listed NetWeaver versions AND has the BSP Test Application IT00 deployed with user input reflected without encoding in the response.
