CVE-2024-9716 is a use-after-free vulnerability classified under CWE-416 found in Trimble SketchUp Viewer version 22.0.316.0. The flaw arises from the software's SKP file parser failing to verify the existence of objects before performing operations on them, leading to a use-after-free condition. This memory corruption vulnerability can be triggered remotely when a user opens a crafted malicious SKP file or visits a malicious webpage containing such a file. Exploiting this vulnerability allows an attacker to execute arbitrary code within the context of the SketchUp Viewer process, potentially leading to full system compromise depending on the privileges of the user running the application. The CVSS v3.0 base score is 7.8, reflecting high severity with attack vector local (requiring user interaction), low attack complexity, no privileges required, and high impact on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the vulnerability poses a significant risk due to the widespread use of SketchUp Viewer in professional design and engineering environments. The vulnerability was reported by the Zero Day Initiative (ZDI) as ZDI-CAN-24100 and published on November 22, 2024. No patches are currently listed, so users must rely on mitigation until an official update is released.

The impact of CVE-2024-9716 is substantial for organizations using Trimble SketchUp Viewer, especially in sectors such as architecture, engineering, construction, and design where SKP files are commonly used. Successful exploitation can lead to arbitrary code execution, enabling attackers to install malware, steal sensitive design data, manipulate project files, or disrupt operations. This compromises confidentiality, integrity, and availability of affected systems. Since the vulnerability requires user interaction, social engineering or phishing campaigns could be used to deliver malicious SKP files. The ability to execute code remotely elevates the threat to critical infrastructure and intellectual property protection. Organizations with large user bases of SketchUp Viewer face increased risk of targeted attacks or widespread exploitation once public exploits emerge.

Until an official patch is released, organizations should implement several specific mitigations: 1) Restrict or disable the opening of SKP files from untrusted or unknown sources. 2) Employ application whitelisting and sandboxing to limit SketchUp Viewer’s ability to execute arbitrary code or access sensitive system resources. 3) Educate users on the risks of opening files from unverified sources and train them to recognize phishing attempts. 4) Monitor network traffic and endpoint behavior for suspicious activity related to SketchUp Viewer processes. 5) Use endpoint detection and response (EDR) tools to detect anomalous memory corruption or code execution patterns. 6) Maintain up-to-date backups of critical design files to enable recovery in case of compromise. 7) Once available, promptly apply vendor patches and verify their deployment across all affected systems. These steps go beyond generic advice by focusing on controlling file sources, user behavior, and runtime restrictions specific to this vulnerability.
