NVD · unedited
Trimble SketchUp Viewer SKP File Parsing Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Trimble SketchUp Viewer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of SKP files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-21786.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is a use-after-free vulnerability in Trimble SketchUp Viewer's SKP file parser. The vulnerability stems from the code failing to validate that an object still exists before performing operations on it, allowing an attacker to potentially execute code by leveraging freed memory through a specially crafted malicious SKP file.

MitigationUsers should avoid opening SKP files from untrusted or unknown sources. The vendor will need to release a patch that adds proper validation checks to ensure objects exist before operations are performed on them.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Trimble SketchUp Viewer installation
    Locate SketchUp Viewer on the system - it may be a desktop application or browser plugin. Check the application version by opening the program and navigating to Help > About SketchUp Viewer, or right-click the executable and select Properties to view version information
    Affected if SketchUp Viewer is installed and the version cannot be determined or is below 23.2.101 or 23.2.102
  2. Compare installed version to affected ranges
    Record the full version number shown in the About dialog or file Properties and compare it against the affected version thresholds: versions before 23.2.101 or before 23.2.102 (depending on which release channel the version belongs to)
    Affected if The installed version number is less than 23.2.101 or less than 23.2.102
  3. Confirm vulnerability trigger condition
    Understand that the use-after-free flaw exists in the SKP file parser component, which is invoked whenever SketchUp Viewer opens or processes a SKP file
    Affected if The viewer is used to open SKP files from any source, with higher risk from untrusted or unknown sources

A user is affected if they have Trimble SketchUp Viewer installed with a version lower than 23.2.101 or 23.2.102 and routinely open SKP files in the viewer

Users should avoid opening SKP files from untrusted or unknown sources. The vendor will need to release a patch that adds proper validation checks to ensure objects exist before operations are performed on them.

Recommended fix Moderate confidence

SketchUp Viewer 23.2.102 or later

  1. 1. Visit the official Trimble SketchUp download page or check for updates within the SketchUp Viewer application
  2. 2. Download SketchUp Viewer version 23.2.102 or later
