CVE-2024-30353
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 Out-Of-Bounds Read 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 proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22807.
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 handling, specifically within Doc objects. The flaw results from insufficient validation of user-supplied data during PDF processing, allowing an attacker to read beyond the boundaries of an allocated memory buffer. This can be leveraged to achieve remote code execution in the context of the current user process.

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.
-
Verify Foxit PDF software is installedCheck for Foxit PDF Reader or Foxit PDF Editor in installed programs (Windows: Control Panel > Programs and Features, or check C:\Program Files\Foxit Software or C:\Program Files (x86)\Foxit Software directories)Affected if Foxit PDF Reader or Foxit PDF Editor is present on the system
-
Determine installed Foxit versionOpen Foxit, click Help > About Foxit PDF Reader/Editor to display the exact version number and build informationAffected if The displayed version falls within any of the affected ranges: <= 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 <= 13.0.1.21693; >= 2023.1.0.15510 and <= 2023.3.0.23028 for Editor, or <= 2023.3.0.23028 for Reader
-
Confirm AcroForm processing is possibleThe vulnerability exists in AcroForm handling within Doc objects; any PDF containing AcroForm fields being processed would trigger the vulnerable code pathAffected if User opens or processes PDF files that contain AcroForm fields (common in fillable forms)
You are affected if Foxit PDF Reader (any version <= 2023.3.0.23028) or Foxit PDF Editor (any version matching the listed ranges) is installed and processes PDF files containing AcroForm data.

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 the vendor patch by updating Foxit PDF Reader to the latest version; avoid opening untrusted PDF files from unknown sources until the update is applied.
