Description Preview

Autodesk AutoCAD 2023 contains a memory corruption vulnerability (CWE-787: Out-of-bounds Write) that occurs when processing specially crafted X_B files. When a malicious X_B file is parsed, it can trigger a write access violation that corrupts memory. This vulnerability is particularly concerning because when combined with other vulnerabilities, it could potentially lead to arbitrary code execution in the context of the current process, allowing attackers to run malicious code with the same privileges as the AutoCAD application.

Overview

CVE-2023-29067 affects Autodesk AutoCAD 2023 software. The vulnerability is triggered when parsing maliciously crafted X_B files, which can cause memory corruption through a write access violation. This type of vulnerability is classified as CWE-787 (Out-of-bounds Write), which occurs when software writes data past the end or before the beginning of the intended buffer. The impact of this vulnerability is elevated when chained with other vulnerabilities, as it could potentially enable attackers to execute arbitrary code within the context of the AutoCAD process. This could lead to unauthorized access to sensitive information, system compromise, or further attacks within the network environment where AutoCAD is deployed.

Remediation

Users should immediately update to the latest version of Autodesk AutoCAD as recommended in the vendor's security advisory ADSK-SA-2023-0005. Until the update can be applied, users should exercise caution when opening X_B files from untrusted sources. Implement defense-in-depth strategies such as:

  • Running AutoCAD with minimal privileges
  • Using application control solutions to prevent execution of unauthorized code
  • Implementing network segmentation to limit the impact of potential compromise
  • Regularly backing up critical design files and data
  • Considering the use of virtualized environments for opening untrusted files
