CVE-2020-37183
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 · uneditedAllok RM RMVB to AVI MPEG DVD Converter 3.6.1217 contains a stack overflow vulnerability that allows attackers to execute arbitrary code by overwriting Structured Exception Handler (SEH) registers. Attackers can craft a malicious payload in the License Name input field to trigger a buffer overflow and execute system commands like calc.exe.
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 · moderate confidenceA stack buffer overflow exists in Allok RM RMVB to AVI MPEG DVD Converter 3.6.1217 within the License Name input field. By supplying an overly long string, attackers can overwrite Structured Exception Handler (SEH) records on the stack and achieve arbitrary code execution, as demonstrated by launching calc.exe.

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 the Allok RM RMVB to AVI MPEG DVD Converter installationSearch for the software in standard installation directories (typically C:\Program Files\Allok or C:\Program Files (x86)\Allok) or check the Windows Add/Remove Programs listAffected if The software is found on the system
-
Identify the installed version numberRight-click the executable (usually named Allok RM RMVB to AVI MPEG DVD Converter.exe), select Properties, and check the Details tab for the File VersionAffected if The version is 3.6.1217 exactly, or falls within the 3.6.x family without a later patch
-
Verify the License Name input field existsLaunch the application and navigate to the License/Registration area where users enter their license nameAffected if The application has a License Name input field and accepts user-supplied text (default behavior)
-
Check for signs of prior exploitationReview application logs, crash dumps, or antivirus/EDR alerts related to this application for signs of stack overflow or SEH overwrite attemptsAffected if Any suspicious activity or crash reports associated with this software are found
If Allok RM RMVB to AVI MPEG DVD Converter version 3.6.1217 is installed and has the License Name input field available, the environment is affected by this CVE.

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 dataIf a patched version exists, upgrade immediately. Otherwise, restrict network access to this software, implement application sandboxing, and consider input validation through external mechanisms if the application cannot be updated.
