CVE-2023-40310
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 PowerDesigner Client - version 16.7, does not sufficiently validate BPMN2 XML document imported from an untrusted source. As a result, URLs of external entities in BPMN2 file, although not used, would be accessed during import. A successful attack could impact availability of SAP PowerDesigner Client.
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 · moderate confidenceSAP PowerDesigner Client 16.7 contains an XML External Entity (XXE) vulnerability during BPMN2 XML import. The application processes external entity references in BPMN2 files even when those entities are not used in the document, causing the application to attempt to access specified URLs. This can lead to availability impact through SSRF-like behavior or resource exhaustion.

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 the installed SAP PowerDesigner versionCheck the application version through the 'About' dialog (Help > About) or by locating the installation metadata. Common locations include the installation directory or registry entries under HKLM\Software\SAP\PowerDesigner.Affected if The installed version is exactly 16.7 (version 16.7.0)
-
Verify BPMN2 import functionality presenceConfirm that the BPMN2 import feature is available in the installation. This is typically found in the File > Import menu or through the model's import options under BPMN2 format support.Affected if BPMN2 import capability exists in the installed version
-
Check for recent BPMN2 file importsReview recent import activity or logs to determine whether BPMN2 files have been imported into the model repository or workspace. Examine import history or temporary directories used during import operations.Affected if BPMN2 files have been imported using the affected version
A user is affected if they have SAP PowerDesigner version 16.7 installed and have imported or intend to import BPMN2 XML files from untrusted sources.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedOnly import BPMN2 files from trusted sources. Apply vendor patches when available. Consider implementing XML parsing safeguards such as disabling external entity processing in the XML parser configuration.
- Contact SAP Support or check SAP Security Notes for CVE-2023-40310 to obtain the specific patch for PowerDesigner 16.7
- Apply the official SAP patch for this vulnerability
- If no patch is immediately available, disable BPMN2 XML import from untrusted sources until the patch is released
- Alternatively, use an XML parser with XXE protection enabled when processing BPMN2 files outside of PowerDesigner
