CVE-2020-37181
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 · uneditedTorrent FLV Converter 1.51 Build 117 contains a stack overflow vulnerability that allows attackers to overwrite Structured Exception Handler (SEH) through a malicious registration code input. Attackers can craft a payload with specific offsets and partial SEH overwrite techniques to potentially execute arbitrary code on vulnerable Windows 32-bit systems.
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 stack-based buffer overflow exists in Torrent FLV Converter 1.51 Build 117 within the registration code input field. The vulnerability allows attackers to overwrite the Structured Exception Handler (SEH) on the stack through crafted input with specific offsets, potentially achieving arbitrary code execution on vulnerable 32-bit 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.
-
Confirm Torrent FLV Converter installationLook for Torrent FLV Converter in the list of installed programs (Control Panel > Programs and Features) or check common installation directories such as C:\Program Files\Torrent FLV Converter or C:\Program Files (x86)\Torrent FLV ConverterAffected if The application is present on the system
-
Identify the installed versionRight-click the executable file (typically named torrent flv converter.exe or similar) and select Properties, then check the Details tab for the File Version or Product Version informationAffected if The version is 1.51 Build 117 exactly
-
Determine system architectureOpen System Information (msinfo32) and check the System Type field - look for 'x86' indicating 32-bit Windows or 'x64' for 64-bit WindowsAffected if The system is running a 32-bit (x86) version of Windows; the vulnerability specifically affects 32-bit systems
-
Verify the registration feature existsLaunch the application and locate the registration or activation window, typically found under Help > Register, Help > Enter License Key, or similar menu optionsAffected if The application has a registration code input field that accepts user-supplied text
A user is affected if Torrent FLV Converter version 1.51 Build 117 is installed on a 32-bit Windows system and the registration code input field is accessible.

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 dataSince this appears to be a legacy/abandoned application, the primary mitigation is to discontinue use and replace with actively maintained software. If continued use is required, input validation and bounds checking must be implemented in the registration handling code to prevent buffer overflows.
