Code-Projects Chat System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Code-Projects Chat System version 1.0. The issue arises in the file '/user/fetch_member.php', where the 'id' parameter is not properly sanitized, allowing attackers to inject malicious SQL code. This vulnerability can be exploited remotely, with public knowledge of the exploit available. The injection could be used to manipulate database queries or extract sensitive information by introducing delays in the database response, a technique that can be used to verify the existence of the vulnerability.

Impact

Exploitation of this vulnerability allows for SQL injection, where an attacker can manipulate database queries. This could lead to unauthorized data access, data manipulation, or in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a request to the '/user/fetch_member.php' endpoint with an unsanitized 'id' parameter. The lack of proper input validation will allow for the injection of malicious SQL code, exploiting the application's database query handling.
