CVE Alert: CVE-2025-8892 – Autodesk – Shared Components

**Risk verdict** High risk: memory corruption in Autodesk Shared Components can be triggered by parsing a crafted PRT file, allowing code execution in the user’s context after a local action.

**Why this matters** CAD workflows frequently involve opening PRT files from external sources. A compromised file could disable or seize control of a workstation, expose design data, or enable movement into adjacent systems in a trusted network.

**Most likely attack path** An attacker crafts a malicious PRT and delivers it via email or file sharing; the user opens it with an affected Autodesk product. The exploit is local and UI‑driven, with no privileges required, but if the product runs with high rights, the attacker could attain a high integrity compromise on the host.

**Who is most exposed** Organisations with enterprise Autodesk deployments, especially design studios and manufacturing/architecture firms, where CAD workstations access shared components and networked file stores.

Detection ideas

• Crashes or memory errors in Autodesk processes after opening a PRT.
• Memory dumps or stack traces tied to PRT parsing.
• Unusual Autodesk process activity or privilege changes following receipt of a file.
• Suspicious PRT files or attachments intercepted by email/file security tools.
• EDR alerts for anomalous code execution within Autodesk components.

Mitigation and prioritisation

• Apply vendor patch to affected versions (update to 2026.4 or later); verify in staging before broad rollout.
• Implement least‑privilege execution for CAD workstations; restrict PRT parsing where feasible; enable application allowlisting.
• Enforce strict file‑handling controls: sandbox or isolate external CAD attachments; scan PRT files with updated AV/EDR.
• Change‑management: schedule patch window, communicate to users, and test CAD workflows post‑patch.
• Monitoring: enable memory‑related telemetry and crash reporting for Autodesk processes; watch for post‑patch anomalies.
