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 PHPGurukul Teachers Record Management System 2.1. It has been classified as critical. This affects an unknown part of the file /admin/changeimage.php. The manipulation of the argument tid 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 PHPGurukul Teachers Record Management System 2.1. The 'tid' parameter in the /admin/changeimage.php file is not properly sanitized before being used in SQL queries, allowing remote attackers to inject arbitrary SQL code.

MitigationImplement prepared statements/parameterized queries to sanitize all user inputs, particularly the 'tid' parameter in changeimage.php. Apply immediate input validation and consider restricting admin page access until patched.

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 installed version of PHPGurukul Teachers Record Management System
    Locate the version identifier in the application source code, typically in a version file, changelog, or admin dashboard. Common locations include a version.php file, readme.txt, or the footer of admin pages.
    Affected if The installed version is 2.1 or if the version cannot be determined but matches the affected release.
  2. Verify presence of the vulnerable changeimage.php file
    Locate the file at /admin/changeimage.php within the web application root directory. Check if the file exists on the server.
    Affected if The file /admin/changeimage.php exists in the web application directory.
  3. Check if the admin panel is accessible
    Attempt to access the /admin/ directory or login page via HTTP/HTTPS request to confirm the admin interface is exposed.
    Affected if The admin panel is reachable without authentication restrictions or from untrusted networks.
  4. Review changeimage.php source code for SQL query handling
    Open changeimage.php and examine how the 'tid' parameter is used in database queries. Search for SQL statements (SELECT, UPDATE, INSERT) that incorporate the tid parameter.
    Affected if The 'tid' parameter is directly concatenated into SQL queries without using prepared statements, parameter binding, or input sanitization functions.
  5. Check application configuration for database credentials
    Examine the configuration file (commonly config.php, db.php, or includes/database.php) to confirm the database connection uses standard credentials.
    Affected if The application database is accessible with credentials found in configuration files, indicating potential for data exfiltration if the SQL injection is exploited.

A user is affected if the system runs PHPGurukul Teachers Record Management System version 2.1, the /admin/changeimage.php file exists, and the 'tid' parameter in that file is used in SQL queries without parameterized prepared statements.
