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 STP file in atf_dwg_consumer.dll when parsed through Autodesk applications can lead to a memory corruption vulnerability by write access violation. This vulnerability in conjunction with other vulnerabilities could lead to code execution 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.

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 Autodesk products
    Open Windows Control Panel > Programs and Features, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' in PowerShell to list installed software
    Affected if Any of the following products appear: Autodesk AutoCAD, AutoCAD Architecture, AutoCAD Electrical, AutoCAD Mechanical, AutoCAD MEP, AutoCAD Plant 3D, Civil 3D, or Advance Steel
  2. Verify product version
    Right-click the installed application exe, select Properties, then check the Details tab for File Version or Product Version. Alternatively, run the application and check Help > About
    Affected if The version is 2021.x, 2022.x, 2023.x, 2024.x, or 2025.x and falls below the patched release (2021.1.4, 2022.1.4, 2023.1.5, 2024.1.3, or 2025.0.1)
  3. Locate the vulnerable DLL
    Search the Autodesk installation directory for atf_dwg_consumer.dll. Default paths are typically C:\Program Files\Autodesk\ or C:\Program Files (x86)\Autodesk\
    Affected if The DLL atf_dwg_consumer.dll exists in the product installation folder, indicating the vulnerable component is present

You are affected if you have any of the listed Autodesk products installed with a version in the 2021 through 2025 range that is older than the patched releases (2021.1.4, 2022.1.4, 2023.1.5, 2024.1.3, or 2025.0.1) and the atf_dwg_consumer.dll file is present.

Fixed in 2021.1.42022.1.42023.1.5
Interim mitigation

Apply the vendor patch or update Autodesk applications to the latest version to remediate this vulnerability.

Recommended fix Moderate confidence

Upgrade to the following minimum versions based on your product: AutoCAD/AutoCAD Architecture/Electrical/Mechanical/MEP/Plant 3D 2021.1.4+, 2022.1.4+, 2023.1.5+, or 2024.1.3+ | Civil 3D 2021.1.4+, 2022.1.4+, 2023.1.5+, or 2024.1.3+ | Advance Steel 2021.1.4+, 2022.1.4+, 2023.1.5+, or 2024.1.3+

  1. 1. Identify the exact version of the installed Autodesk product by opening the application, going to Help > About Autodesk [Product Name], and noting the full version number.
  2. 2. Navigate to the Autodesk Account portal at https://account.autodesk.com/ or the official Autodesk support site to access updates and patches.
  3. 3. Locate the appropriate security update for CVE-2024-23132 in the Autodesk Product Support or Security Advisories section.
  4. 4. Download the update corresponding to your product line: For AutoCAD 2021.x, download version 2021.1.4 or later; for 2022.x, download 2022.1.4 or later; for 2023.x, download 2023.1.5 or later; for 2024.x, download 2024.1.3 or later.
  5. 5. Close all running Autodesk applications and ensure any associated processes are terminated.
  6. 6. Run the downloaded installer with administrative privileges and follow the on-screen prompts to apply the security update.
  7. 7. After installation, restart the Autodesk application and verify the updated version by checking Help > About to confirm the patch was applied successfully.
  8. 8. As a supplementary mitigation, implement organizational controls to restrict the handling of untrusted STP files until the update is applied, and configure application sandboxing or endpoint protection where available.
Caveat Minor: Standard AutoCAD update with no major API or workflow changes expected; however, verify compatibility with any custom scripts or third-party add-ins after upgrading
