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 an Out-Of-Bounds Write. 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 crafted PRT (part file) parsed by AutoCAD 2023 or 2024 triggers an out-of-bounds memory write vulnerability. An attacker can exploit this by tricking a user into opening the malicious file, potentially achieving arbitrary code execution in the context of the user's AutoCAD process.

MitigationApply the vendor patch from Autodesk for AutoCAD 2023 and 2024 when available. Until then, avoid opening untrusted PRT files from unknown sources and consider restricting file handling permissions.

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 AutoCAD, or check Programs and Features in Control Panel for installed Autodesk products
    Affected if Any AutoCAD 2023 or 2024 variant is installed (including verticals like Architecture, Civil 3D, Electrical, Mechanical, Advance Steel, LT, Map 3D)
  2. Determine installed version number
    In AutoCAD, type VER or VERIFY at the command line, or check the version in Help > About AutoCAD. Compare against: 2023 versions < 2023.1.4, or 2024 versions < 2024.1.1
    Affected if The installed version is 2023.0.0 through 2023.1.3, or 2024.0.0 through 2024.1.0
  3. Verify .PRT file handling is active
    Check if PRT file association exists in Windows: go to Settings > Apps > Default Apps > Choose defaults by file type, or look for .prt in File Explorer > View > Options > File Associations
    Affected if PRT files are associated with AutoCAD and can be opened directly by double-clicking
  4. Inspect recent PRT file activity
    Check the recent documents folder or Windows Jump List for recently opened .PRT files, or review the drawing pool in working directories for any untrusted PRT files
    Affected if User has opened or may open untrusted PRT files from unknown sources

If AutoCAD 2023 version < 2023.1.4 or 2024 version < 2024.1.1 is installed and the system handles .PRT files, the environment is vulnerable to this attack vector.

Interim mitigation

Apply the vendor patch from Autodesk for AutoCAD 2023 and 2024 when available. Until then, avoid opening untrusted PRT files from unknown sources and consider restricting file handling permissions.

Recommended fix High confidence

AutoCAD 2023.1.4 or later; AutoCAD 2024.1.1 or later (or AutoCAD 2024.1+ for older versions)

  1. 1. Determine the current installed version of AutoCAD or the affected product by opening the application and navigating to Help > About AutoCAD (or equivalent for the specific product).
  2. 2. For AutoCAD 2023.x versions: Upgrade to version 2023.1.4 or later.
  3. 3. For AutoCAD 2024.x versions: Upgrade to version 2024.1.1 or later.
  4. 4. For older versions of AutoCAD (pre-2023): Upgrade to AutoCAD 2024.1 or later.
  5. 5. Download the updated version from the official Autodesk website (www.autodesk.com) under your account's software downloads section.
  6. 6. Ensure all users with access to the affected software apply the update.
  7. 7. After upgrading, verify the version by checking Help > About to confirm the fix is applied.
Caveat Standard upgrade considerations apply - backup existing drawings and custom settings before upgrading; some custom scripts or third-party plugins may require testing for compatibility with the new version
