CVE-2022-23282: Microsoft Paint 3D RCE Vulnerability

CVE-2022-23282 Overview

CVE-2022-23282 is a Remote Code Execution vulnerability affecting Microsoft Paint 3D, a 3D modeling and design application included with Windows 10. This vulnerability allows an attacker to execute arbitrary code on a victim's system through specially crafted files opened by Paint 3D.

Critical Impact

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code with the same privileges as the current user, potentially leading to complete system compromise if the user has administrative privileges.

Affected Products

• Microsoft Paint 3D (all versions prior to patch)

Technical Details for CVE-2022-23282

Vulnerability Analysis

This Remote Code Execution vulnerability in Paint 3D requires user interaction for exploitation. An attacker must convince a user to open a maliciously crafted file using Paint 3D. The attack originates locally, meaning the malicious file must be present on the target system or accessible through a network share. No elevated privileges are required for the attacker to exploit this vulnerability, though user interaction is necessary.

The vulnerability poses significant risk to confidentiality, integrity, and availability of the affected system. Upon successful exploitation, an attacker gains the ability to execute code in the context of the current user, potentially allowing them to install programs, view, change, or delete data, or create new accounts with full user rights.

Root Cause

While Microsoft has not publicly disclosed the specific technical root cause (classified as NVD-CWE-noinfo), Remote Code Execution vulnerabilities in file-parsing applications like Paint 3D typically stem from improper validation or handling of file content during the parsing process. This may involve memory corruption issues when processing malformed 3D model data, texture files, or other embedded content within supported file formats.

Attack Vector

The attack vector for CVE-2022-23282 requires local access with user interaction. A typical attack scenario involves:

1. An attacker crafts a malicious file designed to exploit the vulnerability in Paint 3D
2. The attacker delivers the malicious file to the victim through various means (email attachment, download link, file sharing)
3. The victim opens the malicious file using Paint 3D
4. The vulnerability is triggered during file processing, allowing arbitrary code execution

The attack does not require any privileges beyond convincing the user to open the file, and the scope is unchanged, meaning the exploited component and affected component remain the same.

Detection Methods for CVE-2022-23282

Indicators of Compromise

• Unexpected Paint 3D process activity, especially with unusual parent processes
• Abnormal child processes spawned by Paint 3D (PaintStudio.View.exe)
• Suspicious file access patterns involving recently downloaded 3D model files
• Network connections initiated by Paint 3D to unusual destinations

Detection Strategies

• Monitor for Paint 3D (PaintStudio.View.exe) launching child processes, particularly command shells or scripting engines
• Implement file integrity monitoring for Paint 3D installation directories
• Use endpoint detection and response (EDR) solutions to track process behavior anomalies
• Scan email attachments and downloads for known malicious 3D file formats

Monitoring Recommendations

• Enable Windows Defender Application Control (WDAC) to monitor application behavior
• Configure audit logging for process creation events (Event ID 4688)
• Monitor for unusual file operations in user download and temp directories
• Implement SentinelOne's behavioral AI to detect anomalous process activity from trusted applications

How to Mitigate CVE-2022-23282

Immediate Actions Required

• Apply the latest security updates from Microsoft for Paint 3D via the Microsoft Store
• Consider removing Paint 3D if it is not required for business operations
• Educate users about the risks of opening files from untrusted sources
• Implement application whitelisting to control execution of Paint 3D

Patch Information

Microsoft has addressed this vulnerability through updates to Paint 3D distributed via the Microsoft Store. Users should ensure automatic updates are enabled for Microsoft Store applications or manually update Paint 3D to the latest version. For detailed patch information, refer to the Microsoft Security Response Center advisory.

Workarounds

• Uninstall Paint 3D if the application is not needed for business purposes
• Block or quarantine suspicious 3D file formats (.3mf, .fbx, .obj, .stl, .ply, .glb, .gltf) at email gateways and web proxies
• Implement file type restrictions preventing users from opening 3D model files from untrusted sources
• Run Paint 3D in a sandboxed environment when handling files from external sources

Organizations unable to immediately patch should consider removing Paint 3D from systems where it is not essential. This can be accomplished through the following PowerShell command:

# Remove Paint 3D from Windows 10
Get-AppxPackage Microsoft.MSPaint | Remove-AppxPackage
