CVE-2024-7509 is a stack-based buffer overflow vulnerability identified in Trimble SketchUp version 22.0.354.0, related to improper handling of SKP file parsing. The vulnerability stems from a lack of proper validation on the length of user-supplied data before it is copied into a stack buffer, categorized under CWE-121. This flaw allows an attacker to craft a malicious SKP file that, when opened by a user, triggers a buffer overflow condition. This overflow can overwrite the stack, enabling the attacker to execute arbitrary code within the context of the SketchUp process. The attack vector requires user interaction, such as opening a malicious file or visiting a malicious webpage that delivers the payload. The CVSS v3.0 base score is 7.8, reflecting high severity due to the potential for remote code execution without requiring privileges but needing user interaction. The vulnerability impacts confidentiality, integrity, and availability, as arbitrary code execution can lead to data theft, system compromise, or denial of service. No patches or exploit code are currently publicly available, and no known exploits have been reported in the wild. The vulnerability was reported by the Zero Day Initiative (ZDI) and publicly disclosed in November 2024.

The vulnerability poses a significant risk to organizations using Trimble SketchUp 22.0.354.0, especially those in architecture, engineering, construction, and design industries where SKP files are commonly exchanged. Successful exploitation can lead to full system compromise under the privileges of the SketchUp application, potentially allowing attackers to steal sensitive design data, implant malware, or disrupt operations. Since exploitation requires user interaction, phishing or social engineering campaigns could be used to deliver malicious SKP files. The widespread use of SketchUp in professional environments means that a successful attack could have cascading effects on project confidentiality and integrity. Additionally, compromised systems could be used as footholds for lateral movement within corporate networks. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as exploit development may follow public disclosure.

Organizations should implement the following specific mitigations: 1) Monitor Trimble’s official channels for patches and apply updates promptly once available to eliminate the vulnerability. 2) Restrict the opening of SKP files from untrusted or unknown sources by enforcing strict file handling policies and user education to reduce the risk of user interaction with malicious files. 3) Employ application whitelisting and sandboxing techniques for SketchUp to limit the impact of potential exploitation. 4) Use endpoint detection and response (EDR) tools to monitor for anomalous behavior indicative of exploitation attempts, such as unexpected process spawning or memory corruption indicators. 5) Conduct regular security awareness training focused on recognizing phishing and social engineering tactics that could deliver malicious SKP files. 6) Network segmentation can limit the spread of an attacker if initial compromise occurs. 7) Consider disabling automatic preview or rendering of SKP files in email clients or file explorers to reduce attack surface.
