How the Exploit Works
The vulnerability lies in the unsafe construction of SQL queries in the DataBase.php file of the LogIn-SignUp project. The logIn() and signUp() functions build queries by directly concatenating user input and unvalidated table names, without using prepared statements. This allows an attacker to manipulate the SQL query, thereby causing SQL Injection. While a prepareData() function exists, it is insufficient to prevent SQL injection as it does not sanitize the table name, leaving the system vulnerable to attacks.
Conceptual Example Code
An attacker could exploit this vulnerability by sending a malicious SQL statement in the user input. Here is a conceptual example of how the vulnerability might be exploited:
POST /login HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=admin' OR '1'='1'; -- &password=123456In this example, the SQL query becomes: `SELECT * FROM Users WHERE username = ‘admin’ OR ‘1’=’1′; –‘ AND password = ‘123456’`. The SQL injection effectively comments out the password check, allowing the attacker to bypass authentication.
Mitigation Guidance
A vendor patch for the CVE-2025-51092 vulnerability has been released and its immediate application is highly recommended. In cases where immediate patching is not feasible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation. However, these measures should not replace patching the software as the ultimate remediation step.
