CVE-2022-37372
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 PDF-XChange Editor. 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 PDF files. Crafted data in a PDF file can trigger a write 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-17809.
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 confidenceA buffer overflow vulnerability in PDF-XChange Editor's PDF parsing engine allows remote attackers to execute arbitrary code via a specially crafted PDF file. The vulnerability occurs when parsing malformed PDF data that triggers a write operation past the end of an allocated buffer, enabling code execution under the current user's context.

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 if PDF-XChange Editor is installedLook for PDF-XChange Editor in the list of installed programs via Control Panel > Programs and Features, or use the system search function to locate the application executableAffected if PDF-XChange Editor is present on the system
-
Identify the installed version of PDF-XChange EditorRight-click on the PDF-XChange Editor application shortcut or executable, select Properties, and view the version information on the Details tab. Alternatively, open the application, go to Help > About to display the version numberAffected if The displayed version is 9.3.361.0 exactly (no other version numbers are affected by this CVE)
-
Verify the PDF parsing component versionWithin PDF-XChange Editor, navigate to Help > About > Technical Support or check any available component information dialogs that display the parsing engine versionAffected if The parsing engine version information shows build 361.0 associated with version 9.3.361.0
If PDF-XChange Editor is installed and the exact version is 9.3.361.0, the environment is vulnerable to this buffer overflow when processing malformed PDF files.

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 dataUpdate PDF-XChange Editor to the latest patched version; avoid opening untrusted or unexpected PDF files from unknown sources; implement email gateway filtering for suspicious attachments.
