CVE-2023-2702
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 · uneditedAuthorization Bypass Through User-Controlled Key vulnerability in Finex Media Competition Management System allows Authentication Abuse, Authentication Bypass. This issue affects Competition Management System: before 23.07.
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 confidenceThis is an Insecure Direct Object Reference (IDOR) authorization bypass where an attacker can manipulate a user-controlled key parameter (likely a database ID or object identifier) to access or modify competition management data belonging to other users, effectively bypassing authentication and authorization checks.

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.
-
Check the installed version of Finexmedia Competition Management SystemLocate the software version information in the application admin panel, about page, or version file typically stored in the application root directory. Common locations include a 'version.php', 'info.php', or the system administration interface.Affected if The installed version is any version prior to 23.07 (for example, 23.06, 23.05, 22.x, or earlier releases).
-
Identify endpoints accepting user-supplied object identifiersReview application URLs and API endpoints that contain numeric or alphanumeric ID parameters, such as /competition/view?id=123 or /competition/edit?id=456. These typically appear in competition management, registration, or scoring-related routes.Affected if The application uses URL parameters to reference competition, user, or record IDs without encapsulated object references.
-
Verify if authorization is enforced on IDOR-vulnerable endpointsLog in as a standard user and attempt to access another user's competition data by modifying the ID parameter in the URL. For example, if viewing competition ID=1 works, try incrementing to ID=2, ID=3, or other values to see if unauthorized data is returned.Affected if The application returns competition data, registration details, or management options for user IDs that do not belong to the authenticated session, indicating broken access control.
-
Check for absence of ownership validation in API responsesInspect API responses or application logs when accessing competition records via manipulated IDs. Look for whether the server validates that the requesting user owns or has permission to access the specific competition record.Affected if The system returns full competition details or allows modification actions (edit, delete, register) on records owned by other users without returning a 403 Forbidden or access denied error.
You are affected if the installed Finexmedia Competition Management System version is below 23.07 AND the application permits access to competition data belonging to other users by simply changing ID parameters in the URL or API requests.

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.
dbcve · scoped23.07
Upgrade to Competition Management System version 23.07 or later, which contains proper authorization validation for user-controlled keys. If upgrading is not immediately possible, implement strict access control checks on all endpoints that accept user-supplied identifiers.
Competition Management System version 23.07
- 1. Identify the current version of the Finex Media Competition Management System installation
- 2. Review the current installation documentation or consult vendor for upgrade procedures specific to your deployment method
- 3. Ensure a complete backup of the database and configuration files before proceeding with the upgrade
- 4. Download the Competition Management System version 23.07 from the official vendor distribution channels
- 5. Follow the vendor's documented upgrade procedure to install version 23.07
- 6. Verify the upgrade was successful by checking the system version
- 7. Test that the authorization mechanisms are functioning correctly after the upgrade
- 8. Monitor system logs for any unusual activity during and after the upgrade process
