The vulnerability identified as CVE-2024-7375 represents a critical sql injection flaw within the SourceCodester Simple Realtime Quiz System version 1.0. This system, designed for real-time quiz administration, contains a dangerous processing flaw in the /my_quiz_result.php file that allows attackers to manipulate the quiz parameter. The vulnerability's classification as critical stems from its remote exploitation capability and the public availability of exploit code, making it immediately dangerous to deployed systems. The flaw specifically manifests when user input containing the quiz parameter is processed without proper sanitization or parameterization, creating an avenue for malicious sql commands to be executed against the underlying database.
The technical exploitation of this vulnerability occurs through the manipulation of the quiz argument within the /my_quiz_result.php file, which serves as the entry point for sql injection attacks. When an attacker submits malicious input through the quiz parameter, the application fails to properly validate or escape the input before incorporating it into sql queries. This allows for the injection of malicious sql payloads that can execute arbitrary commands on the database server, potentially leading to complete database compromise, data exfiltration, or unauthorized access to sensitive user information. The vulnerability follows common sql injection patterns where insufficient input validation enables attackers to manipulate the intended sql query execution flow.
The operational impact of CVE-2024-7375 extends beyond simple data theft, as it provides attackers with the capability to escalate privileges and potentially gain full control over the application's backend infrastructure. Remote exploitation means that attackers do not require physical access to the system, enabling them to target vulnerable installations from anywhere on the internet. The public disclosure of exploit code significantly increases the risk to affected organizations, as it removes the requirement for advanced technical skills to carry out attacks. This vulnerability directly impacts the confidentiality, integrity, and availability of the quiz system's data, potentially affecting thousands of users who participate in quizzes through this platform.
Organizations utilizing the SourceCodester Simple Realtime Quiz System must implement immediate mitigations to address this vulnerability. The primary remediation involves implementing proper input validation and parameterized queries for all user-supplied data, specifically within the quiz parameter handling in /my_quiz_result.php. This aligns with established security practices and addresses the underlying CWE-89 sql injection weakness that forms the root cause of the vulnerability. Additional defensive measures should include web application firewall rules to detect and block malicious sql injection patterns, regular security auditing of application code, and comprehensive database access controls to limit potential damage from successful exploitation attempts. The vulnerability also highlights the importance of keeping web applications updated and patched, as this issue represents a preventable security flaw that could have been addressed through proper code review and security testing procedures.
