CVE-2024-9717 is a vulnerability identified in Trimble SketchUp Viewer version 22.0.316.0, specifically related to the parsing of SKP files, the native file format used by SketchUp. The root cause is a use of an uninitialized variable (CWE-457) during the file parsing process. When the software processes a maliciously crafted SKP file, it accesses memory that has not been properly initialized, which can lead to unpredictable behavior including the execution of attacker-controlled code. This vulnerability allows a remote attacker to execute arbitrary code within the context of the current user process. Exploitation requires user interaction, such as opening a malicious SKP file or visiting a malicious webpage that triggers the file parsing. The CVSS v3.0 base score is 7.8, indicating high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits have been reported yet, the vulnerability was responsibly disclosed and assigned by the Zero Day Initiative (ZDI) as ZDI-CAN-24101. The lack of a patch at the time of publication increases the urgency for organizations to implement mitigations or restrict usage until updates are available.

The vulnerability allows remote attackers to execute arbitrary code on affected systems, potentially leading to full system compromise under the context of the current user. This could result in unauthorized access to sensitive data, installation of malware, lateral movement within networks, and disruption of services. Since SketchUp Viewer is used globally by architects, engineers, and designers for 3D model visualization, exploitation could impact intellectual property confidentiality and operational integrity. The requirement for user interaction limits mass exploitation but targeted attacks against high-value individuals or organizations remain a significant risk. The high CVSS score reflects the potential for severe damage if exploited, including data breaches and system outages. Organizations that integrate SketchUp Viewer into their workflows, especially those in construction, engineering, and design sectors, face increased exposure. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as exploit code may emerge following public disclosure.

Until an official patch is released, organizations should implement the following mitigations: 1) Restrict or disable the use of SketchUp Viewer version 22.0.316.0 where feasible, especially on systems with sensitive data or network access. 2) Educate users to avoid opening SKP files from untrusted or unknown sources and to be cautious about visiting suspicious websites. 3) Employ application whitelisting and sandboxing techniques to limit the ability of the SketchUp Viewer process to execute arbitrary code or affect other system components. 4) Monitor network and endpoint logs for unusual behavior indicative of exploitation attempts, such as unexpected process launches or memory access violations. 5) Use endpoint detection and response (EDR) tools to detect anomalous activity related to SketchUp Viewer. 6) Prepare to deploy patches promptly once Trimble releases an update addressing this vulnerability. 7) Consider network segmentation to isolate systems running SketchUp Viewer from critical infrastructure. These steps go beyond generic advice by focusing on user behavior, process containment, and proactive monitoring tailored to the specific threat vector.
