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.
-
Locate SlimPDFReader installationSearch for SlimPDFReader.exe in common installation directories such as C:\Program Files\Investintech\SlimPDFReader\, C:\Program Files (x86)\Investintech\SlimPDFReader\, or use PowerShell command: Get-ChildItem -Path C:\ -Recurse -Filter SlimPDFReader.exe -ErrorAction SilentlyContinueAffected if SlimPDFReader.exe is found on the system
-
Identify installed versionRight-click on SlimPDFReader.exe, select Properties, then view the Details tab for Product Version. Alternatively, run: (Get-Item 'C:\Program Files\Investintech\SlimPDFReader\SlimPDFReader.exe').VersionInfo.ProductVersionAffected if Product version is 2.0.13 or earlier
-
Confirm executable is the vulnerable binaryVerify the file SlimPDFReader.exe exists at the identified path and matches the filename exactly as 'SlimPDFReader.exe' from InvestintechAffected if The executable is confirmed as SlimPDFReader.exe from Investintech
-
Assess if application is in active useCheck for recent file access or process activity: Get-Process | Where-Object {$_.ProcessName -like '*SlimPDF*'} or review Prefetch files in C:\Windows\Prefetch for SlimPDFReader activityAffected if SlimPDFReader has been recently executed or is present in startup configurations
The environment is affected if SlimPDFReader.exe version 2.0.13 or earlier from Investintech is installed on the system.

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.
dbcve · scopedSince SlimPDFReader is discontinued and no longer supported, the recommended remediation is to migrate to an actively maintained PDF reader solution; no vendor patch is expected.
- This product (Investintech SlimPDFReader) has been discontinued by the vendor with no patch or fixed version available.
- Migrate to an alternative supported PDF reader such as Adobe Acrobat Reader, Foxit Reader, or Sumatra PDF.
- If migration is not immediately possible, isolate the system running SlimPDFReader in a restricted network environment to limit exposure to potential exploitation.
