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 detected in code-projects Simple Chat System 1.0. This vulnerability affects unknown code of the file sendMessage.php. The manipulation of the argument type/length/business parameter validity results in sql injection. The attack may be launched remotely. The exploit is now 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 · moderate confidence

SQL injection vulnerability in code-projects Simple Chat System 1.0's sendMessage.php allows remote attackers to inject malicious SQL commands through the type/length/business parameter validity arguments. The vulnerability is exploitable remotely and a public exploit exists, enabling unauthenticated attackers to manipulate database queries.

MitigationReplace dynamic SQL queries with parameterized queries (PDO prepared statements) and implement proper input validation on all user-supplied parameters in sendMessage.php.

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 Simple Chat System installation
    Locate the code-projects Simple Chat System application files on the server. Search for chat-related PHP files or directories containing 'chat' in the name.
    Affected if The application is installed and contains PHP files for the chat system
  2. Check for sendMessage.php
    Look for the file sendMessage.php in the web-accessible directory of the chat system application.
    Affected if The file sendMessage.php exists in the application directory
  3. Verify application version
    Check the application version by examining any version files, headers, or documentation files in the installation directory. Compare against version 1.0.
    Affected if The installed version is Simple Chat System 1.0
  4. Inspect vulnerable parameters in sendMessage.php
    Open sendMessage.php and search for usage of 'type', 'length', or 'business' parameters in the code. Look for how these parameters are handled in SQL query contexts.
    Affected if The code uses type, length, or business parameters in SQL queries without proper parameterization
  5. Check for dynamic SQL query usage
    Examine the SQL queries in sendMessage.php that incorporate the type/length/business parameters. Look for string concatenation or string formatting in query construction rather than prepared statements or parameterized queries.
    Affected if The SQL queries concatenate user-supplied parameter values directly into query strings without using prepared statements

A user is affected if they have code-projects Simple Chat System 1.0 installed with sendMessage.php present and the type/length/business parameters are used in dynamically constructed SQL queries.
