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 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-23900.

dbcve analysis · high confidence

A use-after-free vulnerability in Foxit PDF Reader's AcroForm handling allows remote attackers to execute arbitrary code by convincing users to open malicious PDF files. The flaw stems from the lack of validating object existence before performing operations on them, leading to memory corruption that can be leveraged for code execution in the context of the current process.

MitigationOrganizations should update Foxit PDF Reader to the latest patched version once available, and users should be trained to avoid opening untrusted PDF files. Consider disabling JavaScript execution in Foxit Reader to reduce the attack surface.

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 installed programs for Foxit PDF Reader or Foxit Pdf Editor. In Windows, open Control Panel > Programs and Features or check Add/Remove Programs. The product name will indicate whether you have Reader or Editor.
    Affected if Foxit Pdf Reader or Foxit Pdf Editor is installed
  2. Determine installed Foxit version
    In Foxit, click Help > About Foxit PDF Reader/Editor. Alternatively, right-click the Foxit icon, select Properties, and check the version in the Details tab. Record the full version number including build number.
    Affected if Version number cannot be determined or is not visible
  3. Compare version against affected ranges
    Match your installed version to these affected ranges: For Reader: < 2024.2.3.25184. For Editor: < 11.2.11.54113; >= 12.0.0.12394, < 12.1.8.15703; >= 13.0.0.21632, < 13.1.3.22478; >= 2023.1.0.15510, < 2024.2.3.25184
    Affected if Installed version falls within any of the affected ranges listed
  4. Verify AcroForm functionality status
    In Foxit PDF, go to File > Preferences > Forms. Check if AcroForm functionality is enabled. On some versions, AcroForm is enabled by default when opening PDFs.
    Affected if AcroForms are enabled (the exploit cannot trigger if this feature is completely disabled)
  5. Assess user interaction exposure
    Review organizational practices for opening PDF files from untrusted or external sources. The vulnerability requires a user to open a maliciously crafted PDF file.
    Affected if Users routinely open PDF attachments from unknown or untrusted sources

You are affected if you have Foxit PDF Reader or Foxit Pdf Editor installed with a version number that falls within the affected ranges AND users can open untrusted PDF files with AcroForms enabled.

  3. 3. For Pdf Reader (any version <2024.2.3.25184), upgrade to version 2024.2.3.25184 or later
  4. 4. Download the updated version from the official Foxit website at www.foxit.com
  5. 5. Close all Foxit applications before running the installer
  6. 6. Run the installer with elevated privileges and follow the prompts to complete the upgrade
  7. 7. After installation, verify the version number in Help > About Foxit PDF Reader/Editor confirms the new version
Caveat Standard upgrade within same major version should have minimal risk; users on very old versions may need to review plugin/extension compatibility
