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, which was classified as critical, was found in Campcodes Advanced Online Voting System 1.0. This affects an unknown part of the file /index.php. The manipulation of the argument voter leads to sql injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may 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

A critical SQL injection vulnerability exists in Campcodes Advanced Online Voting System 1.0 in the /index.php file. The 'voter' parameter is not properly sanitized before being used in SQL queries, allowing remote attackers to inject arbitrary SQL commands.

MitigationReplace dynamic SQL queries with prepared statements/parameterized queries in index.php and any other files handling the voter parameter to neutralize SQL injection vectors.

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. Identify the installed application version
    Locate the application files and check version documentation, headers, or meta files. Look for version indicators in the source code, README files, or admin panels.
    Affected if The installed version is Campcodes Advanced Online Voting System 1.0
  2. Verify the vulnerable endpoint exists
    Check if the /index.php file exists in the web root of the application.
    Affected if The file /index.php is present and accessible via the web server
  3. Confirm the voter parameter is accepted
    Submit a request to /index.php with a voter parameter (e.g., ?voter=test) and verify the application processes it without rejecting or sanitizing the input.
    Affected if The voter parameter is accepted and reflected in the response without validation or error messages
  4. Test for SQL injection in the voter parameter
    Send a SQL injection test payload via the voter parameter (e.g., voter=1' OR '1'='1) and observe if the application returns database errors, unexpected results, or behaves differently than with normal input.
    Affected if The application returns SQL syntax errors, database information, or allows manipulation of query logic through the voter parameter
  5. Review source code for lack of prepared statements
    Examine the PHP code in /index.php and related database files to check if queries use prepared statements or parameterized queries, or if user input is concatenated directly into SQL strings.
    Affected if Code shows direct string concatenation of the voter parameter into SQL queries without using prepared statements or input sanitization

A user is affected if they are running Campcodes Advanced Online Voting System version 1.0 and the /index.php endpoint accepts the voter parameter without proper input validation or parameterized queries.
