CVE-2023-31407
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 · uneditedSAP Business Planning and Consolidation - versions 740, 750, allows an authorized attacker to upload a malicious file, resulting in Cross-Site Scripting vulnerability. After 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 confidenceStored Cross-Site Scripting vulnerability in SAP Business Planning and Consolidation versions 740 and 750 allows authenticated attackers to upload malicious files containing XSS payloads. When other users access these uploaded files, the embedded JavaScript executes in their browsers, enabling session hijacking or data theft.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed SAP BPC versionAccess SAP BPC administration console or check system information via transaction code DB02 for SAP BPC components, or inspect the installed package version through SAP LM (Landscape Management). Compare the version number to 740 or 750.Affected if The installed version is exactly 740 or 750.
-
Verify file upload functionality is accessibleLog in as an authenticated user and navigate to the document management or file upload sections of SAP BPC. Check if the upload interface allows uploading files without additional security restrictions.Affected if Authenticated users can access and use the file upload feature without content-type or extension validation.
-
Inspect file serving mechanismUpload a test file (e.g., a harmless text file) through the BPC interface, then attempt to access/download it. Observe if the file is served with proper Content-Type headers and whether file contents are sanitized before rendering.Affected if Uploaded files are served with MIME types that could cause browsers to execute embedded scripts (e.g., HTML, SVG) or are served without sanitization.
-
Check for Content Security Policy enforcementInspect HTTP response headers when accessing uploaded files in BPC. Look for Content-Security-Policy headers that restrict script execution. Use browser developer tools or a tool like curl to capture headers.Affected if Content-Security-Policy headers are missing or allow inline script execution (unsafe-inline).
Your environment is affected if SAP Business Planning and Consolidation version 740 or 750 is installed AND the file upload feature is accessible to authenticated users without proper content validation and CSP protection.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict file upload validation including content-type verification, file extension allowlisting, and sanitization of file contents before storage. Apply Content Security Policy headers and output encoding when files are served to users.
