CVE-2020-37000
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 · uneditedFree MP3 CD Ripper 2.8 contains a stack buffer overflow vulnerability that allows remote attackers to execute arbitrary code by crafting a malicious WAV file with oversized payload. Attackers can leverage a specially crafted exploit file with shellcode, SEH bypass, and egghunter technique to achieve remote code execution on vulnerable Windows systems.

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.
-
Verify Free MP3 CD Ripper is installedCheck for the application in Program Files (typically C:\Program Files\Free MP3 CD Ripper) or via Add/Remove Programs. Also check for running processes named 'freemp3cdripper.exe' or similar.Affected if The software is installed and running on the system
-
Determine the installed versionRight-click the executable (freemp3cdripper.exe) in the installation directory, select Properties, and check the Version tab. Alternatively, view the file properties in Windows Explorer.Affected if The version number is at or below 2.8 (the vulnerable version listed in the CVE)
-
Confirm WAV file parsing capability is presentLaunch the application and attempt to load or preview a standard WAV audio file. The vulnerability triggers specifically during WAV file parsing.Affected if The application successfully parses WAV files (this is the default functionality that contains the flaw)
-
Inspect for suspicious WAV filesCheck user download folders and recent documents for unfamiliar or unexpected WAV files, especially from untrusted sources. Review file sizes - oversized WAV files may indicate exploit attempts.Affected if Unusually large WAV files are present that were obtained from untrusted sources
A user is affected if Free MP3 CD Ripper version 2.8 or lower is installed and can parse WAV files, particularly when opening files from untrusted sources.

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 dataUsers should avoid opening WAV files from untrusted sources and ensure antivirus software is active. The vendor should release a patch that implements proper bounds checking during WAV file parsing.
