CVE-2024-8847
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 Doc Object Out-Of-Bounds Read 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 handling of Doc objects. 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-25198.
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 an out-of-bounds read vulnerability in PDF-XChange Editor's Doc object handling. The flaw results from insufficient validation of user-supplied data when processing Doc objects, allowing an attacker to read past the end of an allocated buffer. Successful exploitation enables remote code execution in the context of the current process, but requires user interaction via a malicious page or file.

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 the application in Program Files folder (typically C:\Program Files\PDF-XChange\PDF-XChange Editor) or check Windows Registry under HKEY_LOCAL_MACHINE\SOFTWARE\Tracker Software Products or HKEY_CURRENT_USER\SOFTWARE\Tracker Software ProductsAffected if PDF-XChange Editor is found on the system
-
Determine the installed version of PDF-XChange EditorRight-click on PDFXEdit.exe in the installation directory, select Properties, then check the Details tab for the Product Version field. Alternatively, open the application, go to Help > About to display version informationAffected if Version equals 10.3.1.387
-
Check if PDF-XChange PDF Tools is installedLook for installation in Program Files (typically C:\Program Files\PDF-XChange\PDF-XChange PDF Tools) or check Windows Registry under the Tracker Software Products keysAffected if PDF-XChange PDF Tools is found on the system
-
Determine the installed version of PDF-XChange PDF ToolsCheck the version property of the main executable (usually PDFXTools.exe) in the installation folder, or look in Windows Registry for the version value under the product's registry keyAffected if Version equals 10.3.1.387
You are affected if either PDF-XChange Editor or PDF-XChange PDF Tools version 10.3.1.387 is installed on your system, as the vulnerability exists in this specific version.
