CVE-2020-37043
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 · unedited10-Strike Bandwidth Monitor 3.9 contains a buffer overflow vulnerability that allows attackers to bypass SafeSEH, ASLR, and DEP protections through carefully crafted input. Attackers can exploit the vulnerability by sending a malicious payload to the application's registration key input, enabling remote code execution and launching arbitrary system commands.
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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed version of 10-Strike Bandwidth MonitorOpen Windows Control Panel, go to Programs and Features, locate 10-Strike Bandwidth Monitor in the list, and note the version column. Alternatively, use PowerShell: Get-ItemProperty 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*' | Where-Object {$_.DisplayName -like '*Bandwidth Monitor*'} | Select-Object DisplayName, DisplayVersionAffected if The displayed version is 3.9 exactly
-
Verify application executable file versionNavigate to the installation directory (commonly C:\Program Files\10-Strike Bandwidth Monitor\), right-click BandwidthMonitor.exe, select Properties, and view the File Version in the Details tabAffected if The file version reads 3.9 or matches the vulnerable release
-
Confirm registration feature is presentLaunch the application, access the Help menu or main window, and locate the registration or license key input optionAffected if The registration key input field is present and accepts text input in the application interface
The environment is affected if 10-Strike Bandwidth Monitor version 3.9 is installed and the registration key input feature is accessible in the application.

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 dataContact the vendor (10-Strike Software) for an immediate patch; until available, isolate the application from untrusted networks and restrict access to the registration functionality.
