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 when parsed through Autodesk AutoCAD 2024 and 2023 can be used to dereference an untrusted pointer. This vulnerability, along with other vulnerabilities, could lead to code execution in 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 · moderate confidence

A maliciously crafted STP file parsed by Autodesk AutoCAD 2023 and 2024 can be used to dereference an untrusted pointer. This vulnerability, when combined with other vulnerabilities, could lead to arbitrary code execution in the context of the current process.

MitigationApply the vendor security update when released; until then, exercise extreme caution with STP files from untrusted sources and consider disabling automatic file parsing where possible.

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
    Open AutoCAD and go to Help > About Autodesk AutoCAD, or check Programs and Features in Control Panel for installed Autodesk software
    Affected if Any AutoCAD family product (AutoCAD, AutoCAD Architecture, Civil 3D, Electrical, Mechanical, Advance Steel, Map 3D, or LT) is installed
  2. Determine installed version number
    In AutoCAD, type 'VER' or 'ABOUT' at the command line to display the version and build number
    Affected if Version cannot be determined or shows as unknown
  3. Compare version against affected ranges
    Match the installed version to these vulnerable ranges: 2023.0.0 through 2023.1.3 (or any version < 2023.1.4); 2024.0.0 through 2024.1.0 (or any version < 2024.1.1 for 2024 products, or < 2024.1 for some products)
    Affected if Installed version falls within any of the affected ranges listed
  4. Verify STP file handling is enabled
    Check if the application is configured to automatically open or parse STP files. Look in Options > File > Trusted File Locations, or check file association settings for .stp files
    Affected if STP file parsing or automatic opening is enabled and the system processes STP files

The environment is affected if any AutoCAD variant from the 2023 or 2024 product lines is installed with a version matching the affected ranges and STP file parsing is active.

Recommended fix High confidence

AutoCAD 2023.1.4 or later; AutoCAD 2024.1.1 or later (or 2024.1 for AutoCAD LT)

  1. 1. Identify the specific AutoCAD product and version currently installed from the affected versions list.
  2. 2. For AutoCAD 2023.x versions (>= 2023.0.0, < 2023.1.4): Upgrade to version 2023.1.4 or later.
  3. 3. For AutoCAD 2024.x versions (>= 2024.0.0, < 2024.1.1): Upgrade to version 2024.1.1 or later.
  4. 4. For AutoCAD LT (additional version < 2024.1): Upgrade to version 2024.1 or later.
  5. 5. Download the updated version from the official Autodesk website or your Autodesk Account portal.
  6. 6. Install the update following standard Autodesk installation procedures.
  7. 7. Verify the installed version matches or exceeds the fixed version numbers.
  8. 8. Re-test any STP file workflows to ensure normal functionality after the update.
Caveat Review Autodesk release notes for new features and any deprecated functionality in the upgrade versions; ensure custom scripts/plugins are compatible
