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 Application Server JAVA(XML Forms) versions 7.30, 7.31, 7.40, 7.50 does not sufficiently encode user controlled inputs, which allows an authenticated User with special roles to store malicious content, that when accessed by a victim, can perform malicious actions by executing JavaScript, leading to Stored Cross-Site Scripting.

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

Stored Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Application Server JAVA XML Forms component (versions 7.30, 7.31, 7.40, 7.50). An authenticated user with special roles can inject malicious JavaScript into form fields, which persists and executes when other users view the contaminated data.

MitigationApply SAP security patches for CVE-2020-6313. Additionally, implement output encoding on XML Forms rendering and review/restrict user roles that allow content creation in affected components.

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 SAP NetWeaver AS JAVA installation
    Run the SAP JVM version command or check the SAP system information via transaction SM51 or the SAP NetWeaver Administrator (NWA) console
    Affected if The system is running SAP NetWeaver Application Server JAVA
  2. Verify the installed version
    Check the exact version number of SAP NetWeaver AS JAVA through the SAP LMND or NWA system information - look for version 7.30, 7.31, 7.40, or 7.50
    Affected if The installed version is exactly 7.30, 7.31, 7.40, or 7.50
  3. Confirm XML Forms component is in use
    Check if the XML Forms component (com.sap.netweaver.forms or similar) is deployed and active in the SAP NetWeaver AS JAVA system via the NWA Component Navigator or by inspecting the deployed applications
    Affected if The XML Forms component is deployed and accessible in the environment
  4. Identify users with elevated XML Forms roles
    Review user role assignments in SAP via transaction PFCG or the Identity Management console, specifically looking for roles that grant create or write access to XML Forms content
    Affected if Users possess roles that allow creation or modification of content within the XML Forms component

The environment is affected if SAP NetWeaver AS JAVA versions 7.30, 7.31, 7.40, or 7.50 are running with the XML Forms component enabled and users have roles permitting content creation in that component.
