CVE-2022-37391
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 · uneditedThis vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader 11.2.2.53575. 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-17661.
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 confidenceThis is a use-after-free or similar object handling vulnerability in Foxit PDF Reader's AcroForms processing. The lack of validating object existence before operations allows remote code execution when a user opens a maliciously crafted PDF file containing malformed AcroForm data.

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.
-
Check Foxit PDF Reader versionOpen Foxit PDF Reader, go to Help > About Foxit Reader to view the installed version numberAffected if The displayed version is earlier than 12.0.1 (for example, 12.0.0, 11.x, 10.x, etc.)
-
Verify AcroForms feature is enabledIn Foxit PDF Reader, navigate to File > Preferences > Forms to confirm AcroForms processing is enabledAffected if AcroForms processing is turned on (enabled by default)
-
Confirm ability to open PDF filesAttempt to open a PDF file or verify the PDF reader can process standard PDF documentsAffected if PDF files can be opened and processed normally
A user is affected if they have Foxit PDF Reader version earlier than 12.0.1 and can open PDF files with AcroForms enabled.
