CVE-2024-9715 is a use-after-free vulnerability classified under CWE-416 affecting Trimble SketchUp Viewer, specifically version 22.0.316.0. The flaw exists in the SKP file parser, where the software fails to verify the existence of an object before operating on it, leading to a use-after-free condition. This memory corruption can be exploited remotely by an attacker who convinces a user to open a crafted malicious SKP file or visit a malicious webpage hosting such a file. Successful exploitation allows arbitrary code execution within the context of the SketchUp Viewer process, potentially enabling full system compromise depending on user privileges. The vulnerability has a CVSS 3.0 base score of 7.8, indicating high severity, with attack vector local (requiring user interaction), low attack complexity, no privileges required, and impacts on confidentiality, integrity, and availability. Although no public exploits are currently known, the vulnerability was identified and published by the Zero Day Initiative (ZDI) as ZDI-CAN-24098. The lack of a patch at the time of disclosure increases the urgency for mitigation and monitoring.

The impact of CVE-2024-9715 is significant for organizations using Trimble SketchUp Viewer, especially those handling sensitive design or architectural data. Successful exploitation can lead to arbitrary code execution, allowing attackers to install malware, steal intellectual property, or disrupt operations. Since the vulnerability affects the file parsing component, attackers can deliver payloads via email attachments, downloads, or compromised websites, increasing the attack surface. The requirement for user interaction limits automated exploitation but does not eliminate risk, particularly in environments with less security awareness. The compromise of SketchUp Viewer could also serve as a foothold for lateral movement within networks. Organizations in architecture, engineering, construction, and related industries are particularly at risk due to their reliance on this software.

Until an official patch is released, organizations should implement several specific mitigations: 1) Enforce strict file handling policies by restricting the opening of SKP files from untrusted or unknown sources. 2) Use application whitelisting to limit execution of unauthorized files and processes. 3) Employ network-level protections such as email filtering and web content filtering to block malicious SKP files and URLs. 4) Educate users about the risks of opening files or links from untrusted sources, emphasizing the need for caution with SketchUp Viewer files. 5) Monitor endpoint behavior for suspicious activity related to SketchUp Viewer processes, including unusual memory usage or process spawning. 6) Consider running SketchUp Viewer in a sandboxed or isolated environment to contain potential exploitation. 7) Maintain up-to-date backups of critical design files to enable recovery in case of compromise. Once a vendor patch is available, prioritize immediate deployment to eliminate the vulnerability.
