Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

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-21787.

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

Trimble SketchUp Viewer contains a Use-After-Free vulnerability in SKP file parsing where the application fails to validate object existence before performing operations on it. This allows remote code execution in the context of the current process when a user opens a malicious SKP file.

MitigationApply vendor-supplied patches or update to the latest version of Trimble SketchUp Viewer; avoid opening untrusted SKP files from unknown sources.

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. Confirm Trimble SketchUp Viewer is installed
    Check for SketchUp Viewer in installed programs (Windows: Add/Remove Programs, macOS: Applications folder, or search for 'SketchUp' in system search)
    Affected if The application is present on the system
  2. Identify installed version number
    Open SketchUp Viewer, then go to Help > About SketchUp (Windows) or SketchUp > About SketchUp (macOS) to display the version number; alternatively, check the program's entry in Add/Remove Programs or the installer log files
    Affected if Version shown is below 23.2.101 or below 23.2.102 (both ranges are affected)
  3. Determine if SKP file association is active
    Right-click any .skp file and verify it opens with SketchUp Viewer, or check File > Open in the application to confirm SKP files are accessible
    Affected if SKP files can be opened by the viewer (this is the default behavior and required for exploitation)

You are affected if Trimble SketchUp Viewer is installed and the version is either below 23.2.101 or below 23.2.102, as both version ranges contain the Use-After-Free vulnerability in SKP file parsing.
