CVE-2019-7359
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 · uneditedAn exploitable heap overflow vulnerability in the AcCellMargin handling code in Autodesk Advance Steel 2018, Autodesk AutoCAD 2018, Autodesk AutoCAD Architecture 2018, Autodesk AutoCAD Electrical 2018, Autodesk AutoCAD Map 3D 2018, Autodesk AutoCAD Mechanical 2018, Autodesk AutoCAD MEP 2018, Autodesk AutoCAD P&ID 2018, Autodesk AutoCAD Plant 3D 2018, Autodesk AutoCAD LT 2018, and Autodesk Civil 3D 2018. A specially crafted DXF file with too many cell margins populating an AcCellMargin object may cause a heap overflow, resulting in code execution.
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 confidenceHeap overflow vulnerability in AcCellMargin handling code in Autodesk AutoCAD 2018 and related products. Specially crafted DXF files with excessive cell margin data overflow the heap buffer during parsing, potentially allowing remote code execution.

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 Autodesk productsCheck Windows Programs and Features or use 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' to list installed software and look for Autodesk productsAffected if Any Autodesk AutoCAD, AutoCAD Architecture, AutoCAD Electrical, AutoCAD LT, AutoCAD Map 3D, AutoCAD Mechanical, AutoCAD MEP, or Advance Steel is installed
-
Verify the exact product versionLocate the specific product in the installed programs list and confirm the version is exactly 2018, or check the product About dialog within the applicationAffected if The installed version is exactly 2018 for any of the affected products listed
-
Confirm DXF file handling is possibleCheck if the software can open or import DXF files, which is the attack vector for this vulnerabilityAffected if DXF file import or opening functionality is available in the installed product
-
Inspect recent DXF file processing activityReview application logs, recent file access timestamps, or crash logs for any DXF files that may have triggered parsing issuesAffected if There are recent DXF files that caused parsing errors or crashes in version 2018 software
You are affected if you have Autodesk AutoCAD 2018, AutoCAD Architecture 2018, AutoCAD Electrical 2018, AutoCAD LT 2018, AutoCAD Map 3D 2018, AutoCAD Mechanical 2018, AutoCAD MEP 2018, or Advance Steel 2018 installed, and you open or process DXF 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.
From vendor dataApply vendor patches from Autodesk for affected 2018 products. Until patched, avoid opening DXF files from untrusted sources.
