CVE-2025-45542: Time-based Blind SQL Injection in CloudClassroom PHP Project v1.0

Key Information Summary Vulnerability Overview CVE ID: CVE-2025-45542 Vulnerability Type: Time-based Blind SQL Injection Affected Product: CloudClassroom PHP Project v1.0 Discoverer: Sanjay Singh Vulnerability Details Root Cause: Due to lack of proper input validation and the use of raw SQL statements during registration, the parameter accepts user input and is directly inserted into SQL queries, enabling attackers to execute arbitrary queries via time-based SQL injection techniques. Impact Potential Impact: - Unauthorized execution of SQL commands - Exposure of sensitive data (e.g., associated passwords) - Enumeration of backend databases - Remote code execution related to server subscriptions Mitigation and Recommendations 1. Fix SQL Injection Vulnerability: - Use prepared statements or ORM frameworks. - Implement strict validation and sanitization of user input. 2. Strengthen Application Security: - Deploy a Web Application Firewall (WAF). - Restrict access permissions to sensitive resources. - Enhance SQL injection defense strategies, such as using stored procedures. Root Cause Analysis Code Review: In the registration functionality, user input is directly concatenated into SQL query strings without any filtering or escaping, leading to an SQL injection vulnerability.
