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-22808.

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 Foxit PDF Reader's AcroForm handling, specifically in Doc object operations. The lack of validating object existence before performing operations on the object leads to the UAF condition, which can be leveraged to achieve arbitrary code execution in the context of the current process.

MitigationApply the vendor patch by updating Foxit PDF Reader to the latest version; avoid opening untrusted PDF files or visiting malicious pages until patched.

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. Check if Foxit PDF Reader is installed
    Open Windows Settings > Apps & features, or check Program Files folder for 'Foxit Reader' directory and locate the executable version. Run: Get-ItemProperty 'C:\Program Files\Foxit Software\Foxit Reader\FoxitReader.exe' | Select-Object VersionInfo
    Affected if Foxit PDF Reader version is 2023.3.0.63083 or lower, or 2023.3.0.23028 or lower
  2. Check if Foxit PDF Editor is installed
    Open Windows Settings > Apps & features, or check Program Files folder for 'Foxit PDF Editor' directory and locate the executable version. Run: Get-ItemProperty 'C:\Program Files\Foxit Software\Foxit PDF Editor\FoxitPDFEditor.exe' | Select-Object VersionInfo
    Affected if Foxit PDF Editor version falls within any of these ranges: <= 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; <= 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
  3. Confirm vulnerability trigger condition
    The vulnerability affects AcroForm handling in PDF documents. When a specially crafted PDF containing malicious AcroForm objects is opened, the use-after-free condition can be triggered during Doc object operations
    Affected if User opens untrusted PDF files containing AcroForm content on a vulnerable Foxit version

You are affected if Foxit PDF Reader or Foxit PDF Editor is installed and its version matches any of the affected ranges listed, and you open PDF files that could contain malicious AcroForm content.
