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.
-
Identify the installed applicationLook for SourceCodester Judging Management System in your web server directories. Common paths may include /var/www/html/, /htdocs/, or C:\inetpub\wwwroot\. Search for files named 'edit_contestant.php'.Affected if The application is present on the system
-
Confirm the version numberCheck for version indicators such as a version.php file, README.txt, or metadata in the application. The affected version is 1.0.Affected if The installed version is Judging Management System 1.0
-
Locate the vulnerable fileFind edit_contestant.php within the application directory structure. This is the file containing the vulnerability.Affected if The file edit_contestant.php exists in the application
-
Verify the vulnerable parameter usageOpen edit_contestant.php and search for usage of the 'contestant_id' parameter in database queries. Look for direct insertion into SQL statements without prepared statements or sanitization functions.Affected if The contestant_id parameter is used in SQL queries without parameterized queries or input sanitization
-
Check remote accessibilityDetermine if the application is exposed to network access. Verify whether edit_contestant.php can be accessed without authentication via HTTP/HTTPS.Affected if The application is accessible remotely without authentication
If the Judging Management System version 1.0 is installed with the edit_contestant.php file accessible remotely and the contestant_id parameter is used in unsanitized SQL queries, the environment is affected by CVE-2023-2108.

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 dataFix the SQL injection by implementing parameterized queries/prepared statements for the contestant_id parameter in edit_contestant.php. Validate and sanitize all user inputs before using them in database queries.
