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
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader 11.2.2.53575. 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 handling of AcroForms. 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-17552.

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 if Foxit PDF software is installed
    Open the Windows Start menu, search for 'Foxit', or check Programs and Features in Control Panel for Foxit PDF Reader or Foxit PDF Editor entries
    Affected if Foxit PDF Reader or Foxit PDF Editor is present on the system
  2. Determine the exact version of Foxit PDF Reader
    Launch Foxit PDF Reader, click Help > About Foxit PDF Reader, and note the version number displayed (format is typically like 12.0.x.xxx)
    Affected if The version shown is lower than 12.0.1
  3. Determine the exact version of Foxit PDF Editor if installed
    Launch Foxit PDF Editor, click Help > About Foxit PDF Editor, and note the version number displayed
    Affected if The version is less than 10.1.9, OR is 11.0.0 through 11.2.2 inclusive, OR equals 12.0.0.12394
  4. Confirm AcroForms handling is present (vulnerability trigger condition)
    The vulnerability is triggered automatically when opening any PDF containing AcroForm fields - no manual feature enablement required; the application processes AcroForms by default when parsing PDF documents
    Affected if The installed version is in the affected ranges and the user opens a malicious PDF file with AcroForm content

The system is affected if Foxit PDF Reader version is below 12.0.1, or Foxit PDF Editor version is below 10.1.9, between 11.0.0 and 11.2.2, or equals exactly 12.0.0.12394.
