CVE-2024-30335
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 · uneditedFoxit PDF Reader AcroForm Annotation 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 Annotation objects. 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-22641.
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 confidenceFoxit PDF Reader contains an out-of-bounds read vulnerability in its AcroForm Annotation handling. The lack of proper validation of user-supplied data allows an attacker to read past the end of an allocated buffer, disclosing sensitive information. Exploitation requires user interaction (opening a malicious PDF or visiting a malicious page), and this flaw can be chained with other vulnerabilities for code execution.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Foxit PDF software installationCheck for Foxit PDF Reader or Foxit PDF Editor executable. Common installation paths: C:\Program Files\Foxit Software\Foxit PDF Reader\FoxitReader.exe or C:\Program Files (x86)\Foxit Software\Foxit PDF Reader\FoxitReader.exe. Also check Add/Remove Programs on Windows or dpkg -l on Linux for Foxit packages.Affected if Foxit PDF Reader or Foxit PDF Editor is installed on the system
-
Determine installed Foxit versionOpen Foxit Reader/Editor, go to Help > About Foxit PDF Reader/Editor, or run: 'FoxitReader.exe -version' from command line. Record the full version number shown (e.g., 2023.3.0.23028).Affected if Version cannot be determined or is not displayed
-
Compare version against affected rangesFor Foxit PDF Reader: check if version <= 2023.3.0.23028. For Foxit PDF Editor: check if version <= 11.2.8.53842 OR (version >= 12.0.0 AND <= 12.1.4.15400) OR (version >= 13.0.0 AND <= 13.0.1.21693) OR (version >= 2023.1.0.15510 AND <= 2023.3.0.23028).Affected if Installed version falls within any of the affected version ranges listed above
-
Verify AcroForm feature usageThe vulnerability affects AcroForm Annotation handling. Check if the user works with PDF forms: look for PDF files with fillable form fields, or in Foxit go to Home > Forms to see if any form documents are opened or recently accessed.Affected if AcroForm-based PDF documents are regularly opened or created using Foxit software within the affected version range
A user is affected if Foxit PDF Reader or Foxit PDF Editor is installed with a version matching the affected ranges AND the software is used to handle PDF documents containing AcroForm annotations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied patches for Foxit PDF Reader when available; until then, enforce user awareness to avoid opening untrusted PDF files and consider implementing application control policies to restrict PDF handling from untrusted sources.
