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
A maliciously crafted PRT file when parsed through Autodesk AutoCAD 2024 and 2023 can be used to cause a Heap-Based Buffer Overflow. A malicious actor can leverage this vulnerability to cause a crash, read sensitive data, or execute arbitrary 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 confidence

A heap-based buffer overflow vulnerability in Autodesk AutoCAD 2023 and 2024 allows remote code execution when parsing maliciously crafted PRT (plotter) files. The vulnerability permits an attacker to crash the application, read sensitive data, or execute arbitrary code within the current process context.

MitigationApply the vendor-supplied security patch from Autodesk to all affected AutoCAD 2023 and 2024 installations.

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 installed AutoCAD product and version
    Open AutoCAD, click the Application menu, then click About. The version number appears in the splash screen or About dialog. Alternatively, check the Windows Registry under HKLM\SOFTWARE\Autodesk\AutoCAD\ for the installed version key.
    Affected if The installed version falls within any of these ranges: 2023.0.0 to 2023.1.3, or 2024.0.0 to 2024.1.0 (or < 2024.1 for certain product variants).
  2. Determine the specific AutoCAD variant
    Check whether the installation is base AutoCAD or a vertical product (Advance Steel, Architecture, Civil 3D, Electrical, LT, Map 3D, or Mechanical). This can be identified in the About dialog or the installed program name in Programs and Features.
    Affected if The variant matches one of the affected products listed in the CVE and the version is in the vulnerable range.
  3. Confirm PRT file handling capability
    Verify that the AutoCAD installation includes plotter configuration support, which enables PRT file parsing. This is a standard feature in default AutoCAD installations used for plotter and printer configuration.
    Affected if The installation can open, import, or configure PRT (plotter) files. This is enabled by default in standard AutoCAD installations.

Recommended fix High confidence

Upgrade to AutoCAD 2023.1.4 or later, or 2024.1.1 or later (depending on your product line)

  1. 1. Verify the current installed version of AutoCAD or affected product variant by opening the application, clicking the 'About' button (typically found in the Help menu), or checking 'Add or Remove Programs' in Windows Control Panel.
  2. 2. Close all running Autodesk applications completely before proceeding with the update.
  3. 3. Launch the Autodesk AutoCAD or affected product variant.
  4. 4. Navigate to the 'Manage' tab in the ribbon interface.
  5. 5. Click on 'Updates and Add-ons' or check for updates within the application.
  6. 6. Alternatively, download the update directly from the Autodesk Account portal at accounts.autodesk.com, then go to 'Products and Services' > 'All Products' and locate your product.
  7. 7. Download and install the appropriate update: For 2023.x versions, install update 2023.1.4 or later; For 2024.x versions, install update 2024.1.1 or later.
  8. 8. Restart the application after the update completes.
