CVE-2020-7819
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 · uneditedA SQL-Injection vulnerability in the nTracker USB Enterprise(secure USB management solution) allows a remote unauthenticated attacker to perform SQL query to access username password and other session related information.
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 confidenceSQL injection vulnerability in nTracker USB Enterprise's web interface allows remote unauthenticated attackers to inject malicious SQL queries through unsanitized input parameters, enabling extraction of usernames, passwords, and session tokens from the backend database.

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 nTracker USB Enterprise installationCheck system for nTracker USB Enterprise software installation - look for the application in installed programs or running processesAffected if nTracker USB Enterprise is installed and running on the system
-
Identify installed versionCheck the installed version of nTracker USB Enterprise (typically available in application properties, about section, or installed programs list) and compare against version 5 and belowAffected if Installed version is 5 or any version lower than 5
-
Verify web interface is accessibleConfirm the nTracker web interface is exposed by checking if the application runs a web server (common ports 80, 443, 8080) or by accessing the documented web URL for the productAffected if The web interface is accessible over the network
-
Check for unsanitized input parametersReview web interface forms and input fields for parameters that interact with the backend database without apparent sanitization or parameterized query usageAffected if The web interface accepts user input through parameters that are not validated or sanitized before database queries
User is affected if nTracker USB Enterprise version 5 or below is installed with its web interface accessible and accepting unsanitized user input parameters.

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 dataReplace dynamic SQL queries with parameterized queries/prepared statements across all user input fields, implement strict input validation, and apply principle of least privilege to database accounts.
