Multiple Vulnerabilities in the Autodesk® AutoCAD® Desktop Software

Autodesk ID: ADSK-SA-2023-0005

Product, Service, Component: Autodesk AutoCAD, Advance Steel and Civil 3D

Impact: Out-of-Bounds Read, Integer Overflow, Stack Buffer Overflow, Memory Corruption Read, Memory Corruption Write

Severity: High

Original Publish: 4/06/2023

Last Revised:7/24/2023

Severity CVSS 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

Multiple Autodesk AutoCAD and AutoCAD-based products have been affected by Out-of-Bounds Read, Integer Overflow, Stack Buffer Overflow, Memory Corruption Read, and Memory Corruption Write vulnerabilities.

Description

The details of the vulnerabilities are as follows:

  1. CVE-2023-27912 - A maliciously crafted X_B file when parsed through Autodesk AutoCAD 2023, 2024 can force an Out-of-Bound Read. A malicious actor can leverage this vulnerability to cause a crash or read sensitive data or execute arbitrary code in the context of the current process.

  2. CVE-2023-27913 - A maliciously crafted X_B file when parsed through Autodesk AutoCAD 2023, 2024 can be used to cause an Integer Overflow. A malicious actor can leverage this vulnerability to cause a crash or read sensitive data, or execute arbitrary code in the context of the current process.

  3. CVE-2023-27914 - A maliciously crafted X_B file when parsed through Autodesk AutoCAD 2023, 2024 can be used to write beyond the allocated buffer causing a Stack Buffer Overflow. A malicious actor can leverage this vulnerability to cause a crash or read sensitive data or execute arbitrary code in the context of the current process.

  4. CVE-2023-27915 - A maliciously crafted X_B file when parsed through Autodesk AutoCAD 2023, 2024 could lead to memory corruption vulnerability by read access violation. This vulnerability in conjunction with other vulnerabilities could lead to code execution in the context of the current process.

  5. CVE-2023-29067 - A maliciously crafted X_B file when parsed through Autodesk AutoCAD 2023, 2024 could lead to memory corruption vulnerability by write access violation. This vulnerability in conjunction with other vulnerabilities could lead to code execution in the context of the current process.
