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
The ABAP Keyword Documentation of SAP NetWeaver Application Server - versions 702, 731, 740, 750, 751, 752, 753, 754, 755, 756, 757, for ABAP and ABAP Platform does not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability. On successful exploitation an attacker can cause limited impact on confidentiality and integrity of the application.

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

Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Application Server ABAP Keyword Documentation. The component fails to properly encode user-controlled inputs, allowing attackers to inject malicious scripts that execute in the context of other users' sessions.

MitigationApply the SAP security patch for CVE-2023-0013, which adds proper input encoding to the ABAP Keyword Documentation component. Until patch is available, implement compensating controls such as web application firewall rules filtering malicious payloads.

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
    Log into the SAP system and execute transaction code SM51, or check the kernel version via the system information. Compare the displayed version against the affected list: 702, 731, 740, 750, 751, 752, 753, 754, 755, 756, 757.
    Affected if The installed version matches one of the listed versions.
  2. Determine if ABAP Keyword Documentation is installed
    Check whether the ABAP Keyword Documentation (ABAP Doc) component is present in the system. This can be verified through SAP transaction code SPAM or via the SAP Support Portal by reviewing installed software components for your system.
    Affected if The ABAP Keyword Documentation component is installed on the system.
  3. Confirm web access to ABAP documentation is enabled
    Verify if the SAP web repository for ABAP keyword documentation is accessible via HTTP/HTTPS. This typically involves accessing the documentation portal URL on your SAP system. Check whether the /sap/bc/abap/docu endpoint or similar documentation URLs are reachable.
    Affected if Web-based ABAP keyword documentation is accessible from a browser.
  4. Assess network exposure of the documentation portal
    Determine whether the ABAP documentation web interface is exposed to untrusted networks or the internet. Review firewall rules and web dispatcher configurations that control access to SAP web services.
    Affected if The documentation portal is accessible to users outside the trusted internal network.

The environment is affected if the SAP NetWeaver AS ABAP version matches one of the listed affected versions AND the ABAP Keyword Documentation component is installed and web-accessible.
