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 found in code-projects Online Reviewer System 1.0. This issue affects some unknown processing of the file /system/system/admins/assessments/pretest/exam-update.php. The manipulation of the argument test_id results in sql injection. The attack may be performed from remote. The exploit has been made public and could be used.

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

SQL injection vulnerability in code-projects Online Reviewer System 1.0 allows remote attackers to execute arbitrary SQL commands via the test_id parameter in /system/system/admins/assessments/pretest/exam-update.php. The lack of input sanitization enables complete database compromise without authentication.

MitigationReplace dynamic SQL queries with parameterized statements/prepared statements for the test_id parameter and all user inputs; if no vendor patch exists, implement web application firewall rules and restrict network access to the admin endpoints.

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 Online Reviewer System installation and version
    Locate the application's installation directory. Check for version indicators such as a version file, footer in the web interface, or the main index.php for a version string. Common paths may include /var/www/html/ or similar web root directories.
    Affected if The installed version is Fabian Online Reviewer System 1.0 or any version matching exactly 1.0
  2. Identify the vulnerable exam-update.php file
    Search for the file at /system/system/admins/assessments/pretest/exam-update.php within the web application root directory. Use find or similar commands to locate this specific path.
    Affected if The file exists at the specified path, indicating the vulnerable component is present
  3. Inspect source code for unsanitized test_id parameter
    Open exam-update.php and locate code handling the test_id parameter. Search for SQL queries that incorporate this parameter directly without using prepared statements, parameter binding, or input sanitization functions such as mysqli_real_escape_string or PDO quote().
    Affected if The test_id parameter is used directly in SQL queries without parameterized binding or escaping functions
  4. Verify if the assessments module is accessible
    Attempt to access the /system/system/admins/assessments/pretest/ directory via HTTP request to confirm the module is enabled and reachable without authentication.
    Affected if The module is accessible over the network without requiring authentication credentials

A system is affected if it runs Fabian Online Reviewer System version 1.0 and contains the vulnerable exam-update.php file with unsanitized test_id parameter usage in SQL queries accessible without authentication.

Mitigation

Replace dynamic SQL queries with parameterized statements/prepared statements for the test_id parameter and all user inputs; if no vendor patch exists, implement web application firewall rules and restrict network access to the admin endpoints.
