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 Canteen Management System installationIdentify if SourceCodester Canteen Management System is deployed by checking web server directories for canteen management related files or checking application metadataAffected if The application is SourceCodester Canteen Management System version 1.0
-
Locate removeUser.phpSearch web application directories for the file removeUser.php which contains the vulnerable SQL query handlerAffected if The file removeUser.php exists in the application web root or admin directory
-
Verify application is network accessibleConfirm the web application is accessible over network (not only localhost) as this is a remote SQL injection vulnerabilityAffected if The application is exposed to network/remote access and removeUser.php is accessible via HTTP/HTTPS
-
Check for Parameterized QueriesExamine removeUser.php source code and look for prepared statements or parameterized queries around the id parameter handling in SQL queriesAffected if The id parameter in removeUser.php is used directly in SQL queries without prepared statements or input sanitization
-
Look for signs of exploitationReview web server access logs for suspicious requests to removeUser.php with SQL injection payloads in the id parameterAffected if Log analysis reveals unexpected SQL syntax or common SQL injection patterns in id parameter requests to removeUser.php
You are affected if you have SourceCodester Canteen Management System version 1.0 deployed with removeUser.php accessible and the id parameter handled without parameterized queries

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 and implement proper input validation on the id parameter in removeUser.php.
