NVD · unedited
Foxit PDF Reader PRC File Parsing 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 parsing of PRC files. 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-26773.

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

Foxit PDF Reader contains an out-of-bounds read vulnerability in its PRC file parser due to insufficient validation of user-supplied data. The flaw allows reading past the end of an allocated buffer during PRC file parsing, which can be leveraged to achieve remote code execution in the context of the current user process.

MitigationUsers should avoid opening PRC files from untrusted sources or visiting malicious websites until Foxit releases an official patch addressing this vulnerability.

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 Foxit PDF product and version
    Open Foxit PDF Reader or Foxit PDF Editor, then navigate to Help > About (or similar menu option) to view the exact version number displayed in the About dialog. Alternatively, check the installed program's version property in Windows Programs and Features.
    Affected if The installed version falls within the affected ranges: for Reader, versions < 2025.1.0.27937 or <= 2025.1.0.66692; for Editor, versions <= 13.1.7.23637, >= 2023.1.0.15510 to <= 2023.3.0.23028, >= 2024.1.0.23997 to <= 2024.4.1.27687, or = 2025.1.0.27937, or versions <= 13.1.7.63027, >= 2023.1.0.5558
  2. Confirm PRC file support is present
    Check if Foxit has native PRC (PrcFileS.ax or similar plugin module) support by examining the Foxit plugin folder (commonly in the installation directory under plugins or UPF folder). Look for a PRC-related plugin component or check if the application can open .prc file extensions.
    Affected if The PRC parsing module exists and is accessible within the Foxit installation, meaning the application can process PRC files.
  3. Locate recent PRC files in the environment
    Search for .prc files on local systems using file explorer search or command: dir /s /b C:\*.prc (adjust drive letter as needed). Review recent downloads folder or commonly accessed document directories.
    Affected if PRC files exist in accessible locations and the Foxit version is within the affected ranges, indicating potential exposure if those files originate from untrusted sources.

A user is affected if they have Foxit PDF Reader or Foxit PDF Editor installed with a version number matching the affected ranges AND the application has PRC file handling capability.
