CVE-2022-33886 — Autodesk Autocad security vulnerability

High CVSS 7.8

A maliciously crafted MODEL and SLDPRT file can be used to write beyond the allocated buffer while parsing through Autodesk AutoCAD 2023, 2022, 2021, 2020, and Maya 2023 and 2022. The vulnerability exists because the application fails to handle crafted MODEL and SLDPRT files, which causes an unhandled exception. A malicious actor could leverage this vulnerability to execute arbitrary code.

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
