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 (applications based on Unified Rendering) - versions SAP_UI 754, SAP_UI 755, SAP_UI 756, SAP_UI 757, SAP_UI 758, SAP_BASIS 702, SAP_BASIS 731, allows an attacker to inject JavaScript code that can be executed in the web-application. An attacker could thereby control the behavior of this web-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 AS ABAP Unified Rendering framework allows attackers to inject malicious JavaScript that executes in the browser sessions of other users. This stored XSS enables session hijacking, defacement, or redirection of legitimate users.

MitigationApply SAP security patches for CVE-2023-40624 to affected SAP_UI and SAP_BASIS versions. Implement input validation and output encoding as compensating controls until patches are applied.

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. Check installed SAP NetWeaver AS ABAP version
    Execute transaction code SM51 to display the SAP Application Server ABAP version. Alternatively, use transaction code SWI1 or SWI2 to check software instances. Compare the displayed version against the affected list: 702, 731, 754, 755, 756, 757, or 758.
    Affected if The installed version matches any of 702, 731, 754, 755, 756, 757, or 758.
  2. Verify SAP_UI component version
    Use transaction code SE16N to query table CVERS or execute transaction code SWNCONFIG to check the installed SAP_UI component version and patch level.
    Affected if The SAP_UI component is present at a version level known to contain the unpatched vulnerability.
  3. Verify SAP_BASIS component version
    Use transaction code SE16N to query table CVERS or execute transaction code SWNCONFIG to check the installed SAP_BASIS component version and patch level.
    Affected if The SAP_BASIS component is present at a version level known to contain the unpatched vulnerability.
  4. Confirm Unified Rendering framework is accessible
    Verify that the Unified Rendering framework is enabled by checking transaction code SICF for services under /sap/bc/uir or by confirming web-based ABAP applications are accessible through the SAP Gateway.
    Affected if The Unified Rendering framework is active and exposed via HTTP/HTTPS endpoints.

The environment is affected if the SAP NetWeaver AS ABAP version matches 702, 731, 754, 755, 756, 757, or 758 AND the SAP_UI or SAP_BASIS components contain the unpatched vulnerability with Unified Rendering framework accessible via web interfaces.
