Key Information Affected Product Online Class Record System Product Website https://www.sourcecodester.com/php/12995/online-class-record-system-using-phpmysql.html Affected or Fixed Version V1.0 Software Link https://www.sourcecodester.com/download-code?nid=12995&title=Online+Class+Record+System+Using+PHP%2FMySQL Vulnerability Type SQL Injection Root Cause A SQL injection vulnerability was discovered in the '/admin/login.php' file of the 'Online Class Record System' project. The issue arises because attackers can inject malicious code directly into SQL queries using the value of the 'user_email' parameter, without proper sanitization or validation. This allows attackers to forge input values, manipulate SQL queries, and perform unauthorized operations. Impact Attackers can exploit this SQL injection vulnerability to gain unauthorized database access, leak sensitive data, tamper with data, achieve full system control, or even cause service disruption, posing a serious threat to system security and business continuity. Description During a security review of the "Online Class Record System", a critical SQL injection vulnerability was identified in the "/admin/login.php" file. The vulnerability stems from insufficient validation of user input for the 'user_email' parameter, allowing attackers to inject malicious SQL queries. As a result, attackers can illegally access the database, modify or delete data, and access sensitive information without proper login or authorization. Vulnerability Details and POC Vulnerability Name: 'user_email' parameter Payload Actual Exploitation Screenshot Recommended Remediation 1. Use Prepared Statements and Parameter Binding: - Prepared statements prevent SQL injection by separating SQL code from user input data. When using prepared statements, user-supplied values are treated as plain data, not as executable SQL code. 2. Input Validation and Filtering: - Strictly validate and filter user input to ensure it conforms to expected formats. 3. Minimize Database User Privileges: - Ensure that database accounts used for connections have the minimum necessary privileges. Avoid using accounts with elevated privileges (such as 'root' or 'admin') for routine operations. 4. Regular Security Audits: - Conduct regular code and system security audits to quickly identify and remediate potential security vulnerabilities.
