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 · unedited
A vulnerability was determined in code-projects Online Reviewer System 1.0. Impacted is an unknown function of the file /system/system/admins/assessments/pretest/exam-delete.php. This manipulation of the argument test_id causes sql injection. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized.

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 confidence

A critical SQL injection vulnerability exists in the code-projects Online Reviewer System 1.0 within the exam-delete.php file. The test_id parameter passed to this endpoint is not properly sanitized before being used in database queries, allowing remote attackers to inject malicious SQL statements and potentially exfiltrate, modify, or delete database contents.

MitigationReplace dynamic SQL queries with parameterized queries or prepared statements, implement proper input validation on the test_id parameter, and apply principle of least privilege to the database user account. Consider deploying a WAF as an additional layer of defense.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Fabian Online Reviewer System installation
    Locate the web application directory and identify if the Fabian Online Reviewer System is deployed. Check for characteristic files such as index.php, login pages, or reviewer-specific modules.
    Affected if The Fabian Online Reviewer System version 1.0 is installed and accessible on the server.
  2. Verify exam-delete.php exists
    Search the web root directory for the file exam-delete.php. This is the vulnerable endpoint mentioned in the CVE.
    Affected if The file exam-delete.php exists in the application directory structure.
  3. Check test_id parameter handling in exam-delete.php
    Open exam-delete.php and examine how the test_id parameter is processed. Look for direct insertion of the test_id parameter into SQL queries without using prepared statements or parameter binding.
    Affected if The test_id parameter is used directly in SQL queries without sanitization, prepared statements, or parameterized queries.
  4. Verify application version
    Check the application's version information, typically found in a README file, version config, or the main index page footer.
    Affected if The installed version is exactly 1.0 of the Fabian Online Reviewer System.
  5. Test the vulnerable endpoint
    If accessible, send a crafted request to exam-delete.php with a test_id value to observe database behavior. Use a safe test value and monitor for SQL error messages or unexpected query execution.
    Affected if The application executes the test_id parameter in SQL context without validation, allowing injection.

A user is affected if the Fabian Online Reviewer System version 1.0 is installed and the exam-delete.php file processes the test_id parameter in SQL queries without prepared statements or input sanitization.

Mitigation

Replace dynamic SQL queries with parameterized queries or prepared statements, implement proper input validation on the test_id parameter, and apply principle of least privilege to the database user account. Consider deploying a WAF as an additional layer of defense.
