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 weakness has been identified in code-projects Class and Exam Timetable Management 1.0. Affected by this issue is some unknown functionality of the file /preview7.php. This manipulation of the argument course_year_section/semester causes sql injection. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be exploited.

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 confidence

SQL injection vulnerability in code-projects Class and Exam Timetable Management 1.0 allows remote attackers to inject malicious SQL queries via the course_year_section or semester parameters in /preview7.php. The critical CVSS score of 9.8 indicates complete compromise potential including data exfiltration or database manipulation.

MitigationReplace dynamic SQL queries with parameterized statements/prepared statements in preview7.php, validate and sanitize all user inputs, and apply input validation constraints on course_year_section and semester parameters.

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 the installed product and version
    Locate the Class and Exam Timetable Management System installation directory and check for version indicators such as a version file, about page, or header/footer copyright text showing the version number.
    Affected if The product is Fabian Class and Exam Timetable Management System version 1.0 exactly.
  2. Verify preview7.php exists
    Check for the presence of the file preview7.php in the web root or application directory of the installation.
    Affected if The file preview7.php exists in the application directory.
  3. Inspect the preview7.php source code
    Open preview7.php in a text editor or use 'grep'/'findstr' to search the file contents for SQL query handling involving 'course_year_section' or 'semester' parameters.
    Affected if The file contains SQL queries that directly incorporate the course_year_section or semester parameters without visible parameterization or prepared statements.
  4. Check input handling in preview7.php
    Review the code around $_GET or $_POST requests for course_year_section and semester parameters to see if they are used in SQL statements without sanitization, escaping, or bound parameters.
    Affected if User-supplied input from course_year_section or semester parameters is concatenated directly into SQL queries without visible input validation or use of parameterized queries.

The system is affected if it is running Fabian Class and Exam Timetable Management System version 1.0 with the preview7.php file present and the vulnerable SQL query handling code that directly incorporates course_year_section or semester parameters into queries.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Replace dynamic SQL queries with parameterized statements/prepared statements in preview7.php, validate and sanitize all user inputs, and apply input validation constraints on course_year_section and semester parameters.

Recommended fix Moderate confidence
  1. This product (Class and Exam Timetable Management System 1.0 from code-projects.org) is an abandoned student project with no vendor support or published security patches.
  2. If this system is in production use, migrate to a supported timetable management solution from a vendor that provides regular security updates.
  3. If the application must continue running temporarily, remove or restrict access to the vulnerable /preview7.php file via web server configuration (e.g., .htaccess deny or remove the file).
  4. Implement web application firewall (WAF) rules to block SQL injection attempts targeting the course_year_section and semester parameters.
  5. For permanent operation, refactor the application to use parameterized queries (PDO prepared statements) instead of raw SQL, though this requires significant code changes to an unmaintained codebase.
Caveat No upgrade path available - this is an abandoned student project with no maintained versions
