Autodesk Installer IPC Frame Parser Out-of-Range Substring DoS

Publication date: 2026-08-12

Last updated on: 2026-08-26

Assigner: Autodesk

Description

A maliciously crafted input, when processed by the Autodesk Installer IPC frame parser, may trigger improper validation of an input-specified position or offset, resulting in an out-of-range substring operation. A malicious actor may leverage this vulnerability to cause the NT AUTHORITY\SYSTEM service to terminate unexpectedly, resulting in a denial-of-service condition.

Attack-Flow Graph

Executive Summary

This vulnerability involves a maliciously crafted input that causes the Autodesk Installer IPC frame parser to improperly validate a position or offset. This leads to an out-of-range substring operation, which can crash the NT AUTHORITY\SYSTEM service and cause a denial-of-service condition.

Detection Guidance

This vulnerability involves improper input validation in Autodesk Installer's IPC frame parser, leading to potential denial-of-service via out-of-range substring operations. Detection requires monitoring for crashes in Autodesk services or unusual input handling. Check Autodesk Installer logs for malformed input errors and inspect system event logs for NT AUTHORITY\SYSTEM service terminations.

Impact Analysis

The vulnerability may allow an attacker to cause system crashes, leading to service disruptions. Since it affects a system service, it could impact the stability and availability of the affected system.

Compliance Impact

This vulnerability causes a denial-of-service condition by terminating the NT AUTHORITY\SYSTEM service, which could disrupt critical system operations. For compliance with GDPR or HIPAA, such disruptions may lead to unauthorized data access or service unavailability, potentially violating availability requirements under these regulations.

Mitigation Strategies

Apply patches or updates from Autodesk to fix the improper input validation in the Installer IPC frame parser. Monitor Autodesk's security advisories for updates and restrict access to the affected service until patched.
