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 SQL injection vulnerability in CodeAstro Simple Attendance Management System v1.0 allows remote unauthenticated attackers to bypass authentication via the username parameter in index.php.

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 SQL injection vulnerability in the username parameter of index.php in CodeAstro Simple Attendance Management System v1.0 allows remote unauthenticated attackers to manipulate SQL queries and bypass authentication mechanisms entirely.

MitigationReplace string-concatenated SQL queries in the authentication logic with parameterized queries (prepared statements) and implement proper input validation for all user-supplied 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 application is CodeAstro Simple Attendance Management System
    Check the application source code, footer, or documentation for the product name. Look for files or directories named 'attendance' or 'CodeAstro' in the web root.
    Affected if The installed application is not CodeAstro Simple Attendance Management System v1.0
  2. Verify index.php handles authentication
    Inspect the index.php file in the web root. Look for login functionality that accepts a username parameter via GET or POST request.
    Affected if index.php does not contain authentication logic or does not accept a username parameter
  3. Check if SQL queries use string concatenation with username input
    Search the index.php file for SQL query patterns. Look for queries like 'SELECT ... WHERE username = ' or similar patterns where the username parameter is concatenated directly into the query string without escaping or parameterization.
    Affected if The code contains SQL queries that concatenate the username parameter directly into the query string (e.g., "SELECT * FROM users WHERE username='" + $username + "'")
  4. Confirm the application connects to a database
    Check for database connection configuration files (e.g., db.php, config.php, or connection strings in index.php) that indicate the application uses a SQL database.
    Affected if The application does not use a SQL database for authentication
  5. Determine if the application is exposed to remote attackers
    Verify that index.php is accessible over HTTP/HTTPS without authentication. Check if the login form submits to index.php and the username parameter is processed without authentication checks.
    Affected if index.php is not accessible remotely or requires authentication before processing the username parameter

You are affected if the installed system is CodeAstro Simple Attendance Management System v1.0 with an accessible index.php that uses string-concatenated SQL queries with the username parameter for authentication.
