CVE-2023-22670
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 · uneditedA heap-based buffer overflow exists in the DXF file reading procedure in Open Design Alliance Drawings SDK before 2023.6. The specific flaw exists within the parsing of DXF files. The issue results from the lack of proper validation of the length of user-supplied XRecord data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
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 confidenceA heap-based buffer overflow vulnerability exists in the DXF file parsing functionality of Open Design Alliance Drawings SDK versions prior to 2023.6. The flaw stems from insufficient validation of XRecord data length before copying user-supplied data into a fixed-size heap buffer, allowing an attacker to overwrite adjacent memory and potentially execute arbitrary code by convincing a user to open a malicious DXF file.

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.
-
Locate the ODA Drawings SDK installationSearch for ODA SDK files in common installation directories (C:\Program Files\ODA, C:\Program Files (x86)\ODA, or within the application bin directories). Look for files named 'DrwCommon.dll', 'OdDxf.dll', or similar ODA library files. Check the file properties to identify the version information embedded in the DLL metadata.Affected if The SDK version shown in the file properties is earlier than 2023.6
-
Identify applications using ODA Drawings SDKScan the application for linked ODA libraries (search for 'oda', 'opendesign', 'drawings', 'dwg', 'dxf' in dependency lists or imported DLLs). Review the application's dependencies or plugin directories for ODA-related binaries.Affected if The application links against or includes ODA Drawings SDK libraries for DXF processing
-
Verify the DXF parsing module is in useCheck application logs or configuration for DXF file operations. Examine whether the application accepts or processes DXF file input, particularly through file open/import operations.Affected if The application has DXF file import or processing functionality enabled and used
-
Confirm XRecord handling component existsInspect the ODA SDK binaries for XRecord-related code by examining module information or checking if the DXF parsing module (OdDxfXRecord or similar) is present in the SDK installation.Affected if The OdDxfXRecord or XRecord parsing module is present in the deployed SDK binaries
-
Compare installed SDK version to vulnerability rangeExtract the precise version number from the ODA SDK DLLs (right-click the DLL, select Properties, view Version tab). Compare the full version string against the vulnerable range: any version prior to 2023.6 is affected.Affected if The extracted version number is below 2023.6 (for example, 2023.5, 2023.4, 2022.x, etc.)
The environment is affected if it runs any application using ODA Drawings SDK versions prior to 2023.6 that processes DXF files.
