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 security vulnerability has been detected in code-projects Online FIR System 1.0. Affected by this vulnerability is an unknown functionality of the file /Login/checklogin.php of the component Login. The manipulation of the argument email/password leads to sql injection. The attack is possible to be carried out remotely. The exploit has been disclosed publicly 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

SQL injection vulnerability in the login functionality of code-projects Online FIR System 1.0 at /Login/checklogin.php allows remote attackers to inject malicious SQL queries through the email and password parameters due to unsanitized user input being directly concatenated into SQL statements.

MitigationReplace dynamic SQL queries with parameterized queries/prepared statements in checklogin.php to properly sanitize user input before executing database queries. Input validation and least-privilege database accounts should also be implemented.

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 Online FIR System 1.0 installation
    Locate the web application's root directory and verify the presence of the Online FIR System by checking for typical FIR system files or directory structure.
    Affected if The application directory contains the FIR system files, particularly the /Login/ directory.
  2. Identify the vulnerable login script
    Locate the file /Login/checklogin.php in the web application root directory.
    Affected if The file checklogin.php exists in the /Login/ directory of the application.
  3. Inspect login code for SQL injection vulnerability
    Open /Login/checklogin.php and examine the database query code, specifically looking for SQL statements that directly concatenate the 'email' and/or 'password' parameters without using prepared statements or parameterization.
    Affected if The code shows SQL queries where $_POST['email'] or $_POST['password'] variables are directly concatenated into the query string (e.g., $query = "SELECT * FROM users WHERE email='" . $_POST['email'] . "'").
  4. Check if login form submits to vulnerable endpoint
    Examine the HTML login form (typically in /Login/ or root) to confirm it submits to checklogin.php with email and password parameters.
    Affected if The login form submits user credentials via POST to checklogin.php using parameter names 'email' and 'password'.

The user is affected if the Online FIR System 1.0 is installed and checklogin.php contains direct SQL concatenation of email/password POST parameters without prepared statements or input sanitization.

Mitigation

Replace dynamic SQL queries with parameterized queries/prepared statements in checklogin.php to properly sanitize user input before executing database queries. Input validation and least-privilege database accounts should also be implemented.
