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 Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information 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 proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-24492.

dbcve analysis · high confidence

This is an out-of-bounds read vulnerability in Foxit PDF Reader's AcroForm handling. The flaw exists due to insufficient validation of user-supplied data when processing AcroForms, allowing an attacker to read past the end of an allocated buffer and disclose sensitive information. When combined with other vulnerabilities, this can enable arbitrary code execution in the current process context.

MitigationUsers should refrain from opening untrusted PDF files or visiting malicious websites until Foxit releases an official security update. Organizations should inventory Foxit PDF Reader installations and prepare to deploy vendor patches promptly.

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 software is installed
    Check Program Files or Program Files (x86) folders for Foxit PDF Reader or Foxit PDF Editor directories, or search for 'Foxit' in Add/Remove Programs (Windows) or Applications folder (macOS)
    Affected if Foxit PDF Reader or Foxit PDF Editor is found on the system
  2. Identify the installed Foxit product name
    Open Foxit and go to Help > About Foxit PDF Reader (or About Foxit PDF Editor), or right-click the application in Control Panel > Programs and Features to view the product name
    Affected if The product is either Foxit PDF Reader or Foxit PDF Editor
  3. Determine the installed version number
    In Help > About, note the exact version number displayed (for example: 11.2.10.53951, 12.1.7.15526, 13.1.3.22478, 2023.3.0.23028, or 2024.2.3.25184)
    Affected if A version number is retrieved from the installation
  4. Compare version against affected ranges
    Match the installed version to these ranges: Editor <= 11.2.10.53951; 12.0-12.1.7.15526; 13.0-13.1.3.22478; 2023.0-2023.3.0.23028; 2024.0-2024.2.3.25184. For Reader, any version <= 2024.2.3.25184 is affected.
    Affected if The installed version falls within any of the listed affected ranges for the corresponding product
  5. Verify AcroForm processing capability
    The vulnerability triggers when opening PDF files containing AcroForm fields. No specific configuration check is needed as AcroForm support is built into Foxit's PDF rendering engine.
    Affected if The software can open and process PDF documents with AcroForm content (standard behavior for Foxit PDF Reader/Editor)

If Foxit PDF Reader or Foxit PDF Editor is installed and its version matches any of the affected ranges listed, the environment is vulnerable to CVE-2024-9253 when processing malicious PDF files with AcroForm data.
