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 College Notes Uploading System 1.0. This issue affects some unknown processing of the file /login.php. Executing a manipulation of the argument User can lead to sql injection. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks.

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 the login.php script of College Notes Uploading System 1.0 allows remote attackers to inject malicious SQL queries via the User parameter. The lack of proper input sanitization or parameterized queries in the authentication logic enables attackers to manipulate SQL statements, potentially bypassing authentication or exfiltrating data from the database.

MitigationReplace dynamic SQL query construction with parameterized queries or prepared statements for all user-supplied inputs in login.php. Implement proper input validation and least-privilege database accounts to limit the impact of any successful injection.

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 product installation
    Locate the College Notes Uploading System installation and verify the version is 1.0 by checking the source code, README, or version file
    Affected if The installed version is College Notes Uploading System 1.0 from Code Projects
  2. Locate login.php
    Find the login.php file within the web application's root directory or authentication module folder
    Affected if The login.php file exists in the application
  3. Inspect User parameter handling
    Open login.php and examine how the User parameter is processed in the authentication logic - look for variables receiving user input without sanitization
    Affected if The User parameter is directly used in SQL queries without prepared statements or parameterization
  4. Verify SQL query construction
    Search for SQL query strings (SELECT, INSERT, UPDATE, DELETE) in login.php that concatenate or embed the User parameter directly
    Affected if Dynamic SQL queries concatenate the User input without escaping or using bound parameters
  5. Check for input sanitization functions
    Look for sanitization functions like mysqli_real_escape_string, htmlspecialchars, or validation routines applied to the User parameter before database operations
    Affected if No input sanitization or validation is applied to the User parameter before SQL execution

If the College Notes Uploading System version 1.0 is installed and login.php contains direct SQL query construction using the User parameter without prepared statements or escaping, the environment is affected by this vulnerability.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Replace dynamic SQL query construction with parameterized queries or prepared statements for all user-supplied inputs in login.php. Implement proper input validation and least-privilege database accounts to limit the impact of any successful injection.
