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
Foxit PDF Reader U3D File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader. 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 U3D files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22912.

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 · moderate confidence

This is an out-of-bounds write vulnerability in Foxit PDF Reader's U3D (Universal 3D) file parser. The vulnerability results from insufficient validation of user-supplied data during U3D file parsing, allowing a write operation past the end of an allocated buffer. An attacker can exploit this by tricking a user into opening a malicious PDF file, achieving remote code execution in the context of the current process.

MitigationApply the vendor patch from Foxit when available. Until then, train users to avoid opening PDF files from untrusted sources and consider disabling U3D rendering in Foxit settings if the feature is not required.

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 Foxit PDF product is installed
    Check for Foxit PDF Reader or Foxit PDF Editor in the system: look for the application in Program Files (e.g., C:\Program Files\Foxit Software\Foxit Reader or Foxit PDF Editor), or check Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for entries containing 'Foxit'
    Affected if Foxit PDF Reader or Foxit PDF Editor is present on the system
  2. Determine installed Foxit version
    Open Foxit and navigate to Help > About Foxit Reader (or About Foxit PDF Editor), or right-click the executable file (FoxitReader.exe or FoxitPDFEditor.exe) in Program Files and select Properties > Details to view the File Version
    Affected if The displayed version falls within any of the affected ranges: <= 10.1.12.37872; >= 11.0.0.49893 and <= 11.2.8.53842; >= 12.0.0.12394 and <= 12.1.4.15400; >= 13.0.0.21632 and <= 13.0.1.21693; >= 2023.1.0.15510 and <= 2023.3.0.23028 for Editor, or <= 2023.3.0.23028 for Reader
  3. Check if U3D rendering is enabled
    In Foxit, go to File > Preferences > Page Display (or Settings > Preferences > 3D), look for options related to 'U3D' or '3D content' or 'Universal 3D' rendering. On Windows, the preference may also be stored in the registry under HKCU\Software\Foxit Software\Foxit Reader\Preferences or in the application config file in the AppData folder
    Affected if U3D/3D rendering or parsing is enabled in the application settings (the vulnerability only triggers when parsing U3D content in a PDF)
  4. Identify recent PDF files opened
    Check the application's recent files list (File > Open Recent) or Windows Jump List for recently opened PDF files, or examine the Windows Temp folder and Foxit's temp folder (%LOCALAPPDATA%\Foxit\Foxit Reader\Temp) for suspicious PDF files
    Affected if Any PDF files from untrusted sources were recently opened, as the exploit requires a maliciously crafted PDF with U3D content

The system is affected if Foxit PDF Reader (any version <= 2023.3.0.23028) or Foxit PDF Editor (any version matching the affected ranges) is installed with U3D/3D rendering enabled and the user may have opened untrusted PDF files.
