CVE-2022-30404
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 · uneditedCollege Management System v1.0 is vulnerable to SQL Injection via /College_Management_System/admin/display-teacher.php?teacher_id=.
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 confidenceCollege Management System v1.0 contains a SQL Injection vulnerability in the display-teacher.php admin page via the teacher_id parameter. User-supplied input is not properly sanitized before being used in SQL queries, allowing attackers to manipulate query logic and potentially exfiltrate, modify, or delete database contents.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify College Management System v1.0 is installedLocate the application installation directory and check the version information (such as a version file, about page, or metadata) to confirm the installed version is exactly 1.0Affected if The installed version is College Management System version 1.0
-
Locate display-teacher.php in the web rootSearch the web server document root for the file display-teacher.php. This file is typically found in an admin or faculty directory within the application.Affected if The file display-teacher.php exists in the application directory
-
Inspect teacher_id parameter handling in display-teacher.phpOpen display-teacher.php and examine how the teacher_id parameter is processed. Look for SQL queries that incorporate this parameter directly without using prepared statements, parameterized queries, or input sanitization functions such as mysqli_real_escape_string or PDO quote().Affected if The code contains SQL queries that directly include the teacher_id parameter without sanitization or parameterized queries
-
Confirm admin access to display-teacher.phpAttempt to access the display-teacher.php page through the web browser or via curl, logging in with admin credentials if required. Verify the page accepts the teacher_id parameter and processes it.Affected if The page is accessible and processes the teacher_id parameter in SQL queries without validation
You are affected if you have College Management System v1.0 installed with the display-teacher.php file present and that file uses the teacher_id parameter in unsanitized SQL queries accessible via the admin interface.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace dynamic SQL queries with parameterized queries (prepared statements) and implement strict input validation on the teacher_id parameter. Apply least-privilege database accounts to limit impact of potential compromise.
