Description Preview

CVE-2023-21793 is a remote code execution vulnerability affecting Microsoft's 3D Builder application. This security flaw could potentially allow attackers to execute malicious code remotely on affected systems when a specially crafted file is opened by the application.

Overview

This vulnerability exists in Microsoft's 3D Builder application, which is a 3D modeling and printing utility included with Windows. When exploited successfully, an attacker could execute arbitrary code with the same privileges as the current user. The vulnerability likely involves improper validation or handling of user-supplied input when processing 3D model files. Attackers would typically need to convince users to open a specially crafted malicious file with the vulnerable application to exploit this issue. The exact technical details of the vulnerability have not been publicly disclosed by Microsoft.

Remediation

Users and administrators should apply the security updates provided by Microsoft as soon as possible to address this vulnerability. The patch is available through Windows Update or can be downloaded directly from the Microsoft Update Catalog. Organizations should prioritize patching systems where 3D Builder is actively used. If immediate patching is not possible, consider implementing the following temporary mitigations:

  • Disable or restrict access to the 3D Builder application
  • Implement application control policies to prevent 3D Builder from running
  • Exercise caution when opening 3D model files from untrusted sources
  • Consider using alternative 3D modeling applications until the vulnerability is patched
