Product, Service, Component:
 Autodesk AutoCAD, Advance Steel and Civil 3D
Impact: Out-of-Bounds Write, Heap-based Buffer Overflow, Untrusted Pointer Dereference, Memory Corruption
Severity: High
Original Publish: 8/24/2023
Last Revised: 8/24/2023

Severity

CVSS 3.0 Score

Impact

Low

0.1 - 3.9

A vulnerability where scope and impact of exploitation is restricted and the ability to exploit is extremely difficult.

Medium

4.0 - 6.9

A vulnerability where exploitation is mitigated by factors such as difficulty to exploit, default configuration or ease of identification.

High

7.0 - 8.9

A vulnerability, which if exploited, would directly impact the confidentiality, integrity or availability of user’s data or processing resources.

Critical

9.0 - 10

A vulnerability, which if exploited, would allow remote execution of malicious code without user action.

Summary

Autodesk AutoCAD and certain AutoCAD-based products have been affected by Out-of-Bounds Write, Heap-based Buffer Overflow, Untrusted Pointer Dereference, and Memory Corruption vulnerabilities.

Description

The details of the vulnerabilities are as follows:

1) CVE-2023-29073 - A maliciously crafted MODEL file when parsed through Autodesk AutoCAD 2023 can be used to cause a Heap-Based Buffer Overflow. 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.

2) CVE- 2023-29074 - A maliciously crafted CATPART file when parsed through Autodesk AutoCAD 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.

3) CVE-2023-29075 - A maliciously crafted PRT file when parsed through Autodesk AutoCAD 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.

4) CVE-2023-29076 - A maliciously crafted MODEL, SLDASM, SAT or CATPART file when parsed through Autodesk AutoCAD 2023 could cause memory corruption vulnerability. This vulnerability, along with other vulnerabilities, could lead to code execution in the current process.

5) CVE-2023-41139 - A maliciously crafted STP file when parsed through Autodesk AutoCAD 2023 can be used to dereference an untrusted pointer. This vulnerability, along with other vulnerabilities, could lead to code execution in the current process.

6) CVE-2023-41140 - A maliciously crafted PRT file when parsed through Autodesk AutoCAD 2023 can be used to cause a Heap-Based Buffer Overflow. 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.

*Note: Product list table contents subject to change.

** Note: Users of Autodesk Advance Steel, Autodesk Civil 3D, and the specialized toolsets of AutoCAD need to install either the AutoCAD product update(s) listed above or a more recent product version. These security fixes are not included in the updates specific to individual toolsets.

Recommendations

Autodesk strongly recommends that users of the 2023 versions of Autodesk Advance Steel, Autodesk Civil 3D, AutoCAD, AutoCAD LT, and AutoCAD-based specialized toolsets listed in the table above install the latest AutoCAD or AutoCAD LT 2023 updates, as applicable, via Autodesk Access or the Accounts Portal.

Autodesk strongly recommends that users of the 2024 versions of Autodesk AutoCAD Mac and AutoCAD LT for Mac install the latest AutoCAD Mac or AutoCAD LT for Mac 2024 updates, as applicable, via Autodesk Access or the Accounts Portal.

Customers using previous versions that no longer qualify for full support should plan to upgrade to a supported version as soon as possible to avoid downtime and potential security vulnerabilities. Visit the Autodesk Knowledge Network for more information about previous version support.
