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 AcroForm Use-After-Free 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 handling of Doc objects in 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-22637.

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.

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 installed Foxit product
    Check system for Foxit PDF Reader or Foxit PDF Editor installation. On Windows, examine the installed programs list or check common installation directories.
    Affected if Neither Foxit PDF Reader nor Foxit PDF Editor is installed, then not affected.
  2. Determine installed version
    Locate the executable (FoxitPDFReader.exe or FoxitPDFEditor.exe) and retrieve its file version property, or use system inventory tools to query the installed software version.
    Affected if Unable to determine version, treat as potentially affected.
  3. Compare against affected version ranges
    Match your installed version against all listed vulnerable ranges: For Reader: < 2023.3.0.63083 or < 2023.3.0.23028. For Editor: < 11.1.6.0109; >= 12.0.0.0601 and < 12.1.2.55366; >= 13.0.0.61829 and < 13.0.1.61866; >= 2023.1.0.55583 and < 2023.3.0.63083; plus additional ranges per the CVE details.
    Affected if Version falls within any of the affected ranges listed in the CVE.
  4. Verify AcroForm usage context
    Determine whether the software processes PDF files containing AcroForm fields, as the vulnerability exists specifically in Doc object handling during AcroForm operations.
    Affected if AcroForm-enabled PDFs are regularly processed; however, the vulnerability triggers on specific Doc object operations regardless of user interaction with forms.

User is affected if Foxit PDF Reader or Foxit PDF Editor is installed and the version number falls within any of the vulnerable version ranges specified in the CVE.
