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 detected in SourceCodester Class and Exam Timetabling System 1.0. Affected by this vulnerability is an unknown functionality of the file /archive1.php. Performing a manipulation of the argument sy results in sql injection. Remote exploitation of the attack is possible. The exploit is now 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

SQL injection vulnerability in SourceCodester Class and Exam Timetabling System 1.0's /archive1.php file. The 'sy' parameter is not properly sanitized before being used in SQL queries, allowing remote attackers to inject arbitrary SQL commands.

MitigationReplace dynamic SQL query construction with parameterized queries/prepared statements. Implement proper input validation and sanitization for all user-supplied parameters before database interaction.

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. Locate the vulnerable file archive1.php
    Search web server document roots for archive1.php. On Linux: 'find /var/www -name archive1.php 2>/dev/null' or 'find /home -name archive1.php 2>/dev/null'. On Windows IIS/Apache: check typical web directories like C:\inetpub\wwwroot or where you installed the application.
    Affected if The file archive1.php exists in any web-accessible directory.
  2. Confirm application version
    Check for version files (version.txt, README, or version in footer/meta tags of index.php). Search source code for version strings like '1.0' or 'version'. If no version file exists, check the application's main page or about page.
    Affected if The installed version is 1.0 or the version cannot be determined (treat unknown versions as potentially affected).
  3. Verify the vulnerable parameter exists in the code
    Open archive1.php and search for usage of the 'sy' parameter. Look for code patterns like $_GET['sy'], $_POST['sy'], or Request::input('sy') that handle this parameter. Identify if it is used in database queries.
    Affected if The 'sy' parameter is being read and used in database queries within archive1.php.
  4. Check if the SQL query lacks parameterized preparation
    In archive1.php, examine the SQL query that uses the 'sy' parameter. Look for whether the query uses prepared statements (prepare, bindParam, bindValue), PDO with parameter binding, or mysqli with placeholders. Check if the parameter is concatenated or interpolated directly into the SQL string.
    Affected if The 'sy' parameter is directly concatenated into the SQL query string without using prepared statements or proper escaping functions.

You are affected if archive1.php exists in your SourceCodester Class and Exam Timetabling System installation, the application version is 1.0 or unknown, and the 'sy' parameter is used in SQL queries without prepared statement protection.
