CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

CVE-2026-18958 is a SQL injection vulnerability in the Student-Management-System affecting the loginCheckTest.php file. The flaw allows remote attackers to manipulate the username and password arguments to inject malicious SQL code. This occurs because user input is directly concatenated into SQL queries without sanitization.

Detection Guidance

To detect this SQL injection vulnerability, inspect the Student-Management-System for the file loginCheckTest.php. Check if user inputs from username and password fields are directly concatenated into SQL queries without sanitization. Look for code patterns like 'select * from users where username={$username} and password={$password}'. Test with inputs like ' OR '1'='1' to see if authentication bypass occurs.

Impact Analysis

This vulnerability enables unauthenticated remote attackers to bypass authentication, gain unauthorized access to student or staff accounts, and steal sensitive data like grades or personal information. Attackers could also take over accounts or modify data in the system.

Compliance Impact

This vulnerability likely violates GDPR and HIPAA by exposing sensitive personal data (e.g., grades, staff information) due to unauthorized access. Non-compliance may result in legal penalties, data breach notifications, and reputational damage for affected institutions.

Mitigation Strategies

Immediately replace direct SQL query concatenation with prepared statements in loginCheckTest.php and UserModel.php. Update the validateUser() function to use password_hash() and password_verify() for secure password handling. Remove or hash all default plaintext credentials in the SQL schema to prevent unauthorized access.
