The vulnerability identified as CVE-2022-30455 affects the Badminton Center Management System version 1.0, specifically targeting the SQL injection flaw within the Master.php script. This system manages court rentals and related administrative functions for badminton centers, making it a critical component for facility operations. The vulnerability manifests through the delete_court_rental function parameter, where user input is directly incorporated into SQL queries without proper sanitization or validation mechanisms. The affected endpoint /bcms/classes/Master.php?f=delete_court_rental accepts an id parameter that is processed in a manner susceptible to malicious SQL manipulation, creating an attack vector that could compromise the entire database infrastructure.
The technical implementation of this vulnerability stems from improper input validation and parameter handling within the backend PHP script. When a user submits a request to delete a court rental record, the system fails to properly escape or parameterize the id value before incorporating it into database queries. This allows an attacker to inject malicious SQL code through the id parameter, potentially executing unauthorized database operations such as data extraction, modification, or deletion. The vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses where untrusted data is used in database queries without proper sanitization. This flaw represents a classic example of insecure data handling practices that enable attackers to manipulate the underlying database structure and access sensitive information.
The operational impact of this vulnerability extends beyond simple data compromise, as it could enable attackers to gain unauthorized access to critical facility management information including rental records, customer data, payment information, and operational schedules. An attacker could potentially delete important court rental bookings, modify pricing structures, or extract confidential customer details stored within the system. The consequences could include financial loss, operational disruption, and potential legal implications due to data breaches. This vulnerability also provides a foothold for further attacks within the network, as compromised database credentials could be used to escalate privileges or access other interconnected systems. The attack surface is particularly concerning given that the system manages court rentals, which likely contains personal information and transactional data that would be valuable to cybercriminals.
Mitigation strategies for CVE-2022-30455 should prioritize immediate implementation of proper input validation and parameterized queries to prevent SQL injection attacks. The system administrators must ensure that all user inputs are properly sanitized and validated before being processed in database operations. Implementing prepared statements or parameterized queries would effectively neutralize the vulnerability by separating SQL code from data. Additionally, regular security audits and code reviews should be conducted to identify similar vulnerabilities in other parts of the application. The implementation of web application firewalls and intrusion detection systems can provide additional layers of protection. According to ATT&CK framework, this vulnerability maps to T1190 - Exploit Public-Facing Application, which emphasizes the importance of securing externally accessible applications. Organizations should also consider implementing least privilege principles for database access and regularly updating the system to address known vulnerabilities, as outlined in industry best practices for application security management.
