CVE-2024-8813
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 · uneditedPDF-XChange Editor U3D File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This 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 U3D files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24208.
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 confidencePDF-XChange Editor contains an out-of-bounds write vulnerability in its U3D (Universal 3D) file parsing logic. The vulnerability stems from insufficient validation of user-supplied data during U3D file parsing, allowing an attacker to write data beyond the boundaries of an allocated memory object. Successful exploitation enables arbitrary code execution within 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.
-
Identify PDF-XChange Editor installationOpen PDF-XChange Editor and go to Help > About, or locate the executable (PDFXCview.exe or PDFXEdit.exe) in Program Files and check its file properties for version informationAffected if The reported version is exactly 10.3.0.386
-
Identify PDF-XChange Pdf Tools installationLocate the installed PDF-XChange Pdf Tools components in Program Files and check the version of PDFXCview.exe or related executables via right-click > Properties > DetailsAffected if The reported version is exactly 10.3.0.386
-
Query Windows Registry for exact versionOpen Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{AppName} or HKLM\SOFTWARE\Tracker Software Products, then locate the DisplayVersion valueAffected if The DisplayVersion value equals 10.3.0.386 for either product
-
Verify U3D file parsing is the attack vectorThis vulnerability is triggered when parsing malicious U3D (Universal 3D) content embedded in PDF files - check whether your workflow involves opening PDF files from untrusted sources that may contain 3D contentAffected if You open PDF files from untrusted sources and the installed version is 10.3.0.386
You are affected if PDF-XChange Editor or PDF-XChange Pdf Tools version 10.3.0.386 is installed and you open PDF files (especially from untrusted sources) that could contain malicious U3D objects.

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-provided patches for PDF-XChange Editor immediately. Until patched, instruct users to avoid opening untrusted PDF files or visiting malicious websites, as user interaction (opening a malicious file) is required for exploitation.
