CVE-2021-27042: A maliciously crafted DWG file can be used to write beyond the allocated buffer while parsing DWG files.

A maliciously crafted DWG file can be used to write beyond the allocated buffer while parsing DWG files. The vulnerability exists because the application fails to handle a crafted DWG file, which causes an unhandled exception. An attacker can leverage this vulnerability to execute arbitrary code.

Security readout for executives and security teams

Plain-English summary

This CVE affects several Autodesk design applications when they parse a malicious DWG file. The reported impact is arbitrary code execution, which could put workstations handling external design files at risk. The source bundle does not provide CVSS scoring or active exploitation evidence.

Executive priority

Prioritize remediation for design, engineering, and architecture teams that open external DWG files. Treat this as workstation code-execution risk, not confirmed active exploitation.

Technical view

The vulnerability is described as a write beyond an allocated buffer during DWG parsing, causing an unhandled exception. The CVE states an attacker can leverage the flaw for arbitrary code execution. Affected products include multiple Autodesk 2022.1.1 product lines listed in the source bundle.

Likely exposure

Exposure is most likely on workstations running the listed Autodesk products and processing DWG files from external or untrusted sources. The bundle does not identify server-side exposure or network exploitation.

Exploitation context

No cited source in the bundle reports active exploitation, and the CVE is not marked KEV. The described attack context requires a maliciously crafted DWG file to be parsed by an affected Autodesk application.

Researcher notes

The provided sources do not include CVSS, CWE, exploit maturity, or detailed patched build information. Analysis should remain tied to Autodesk’s advisory and the CVE description unless additional vendor data is available.

Mitigation direction

  • Review Autodesk advisory ADSK-SA-2022-0007 for vendor guidance.
  • Update affected Autodesk products according to Autodesk’s advisory.
  • Limit processing of untrusted DWG files until remediation is complete.
  • Apply normal endpoint protections for users handling external design files.

Validation and detection

  • Inventory hosts running the listed Autodesk products.
  • Confirm installed versions against Autodesk advisory ADSK-SA-2022-0007.
  • Identify workflows that receive DWG files from external parties.
  • Review security telemetry for suspicious DWG delivery or processing.
