CVE-2024-30983 identifies an SQL Injection vulnerability in the phpgurukul Cyber Cafe Management System Using PHP & MySQL version 1.0. The vulnerability is located in the /edit-computer-detail.php script, specifically through the compname parameter, which fails to properly sanitize user input before incorporating it into SQL queries. This allows remote attackers to inject arbitrary SQL commands without authentication or user interaction. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The CVSS v3.1 base score is 7.3, reflecting a high severity due to network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact includes potential unauthorized disclosure of sensitive data, modification of database contents, or disruption of service. No patches or official fixes have been linked yet, and no exploits are currently known in the wild. The vulnerability affects all installations of the specified software version, though exact affected versions are not detailed. This flaw is critical for environments relying on this system for managing cyber cafe operations, as it could compromise customer data and system integrity.

The SQL Injection vulnerability allows attackers to execute arbitrary SQL commands remotely without authentication, potentially leading to unauthorized access to sensitive customer or operational data stored in the backend database. This can result in data leakage, unauthorized data modification, or deletion, which compromises the confidentiality, integrity, and availability of the system. For organizations running cyber cafe management systems, this could mean exposure of customer identities, usage logs, or payment information. Additionally, attackers might leverage this vulnerability to escalate privileges within the database or pivot to other parts of the network. The ease of exploitation and lack of required privileges increase the risk of widespread attacks, especially in environments where this software is deployed without additional protective controls. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the potential for future attacks once exploit code becomes available.

Organizations should immediately review and sanitize all inputs to the compname parameter in the /edit-computer-detail.php file. Implementing parameterized queries or prepared statements is critical to prevent injection of malicious SQL code. If source code access is available, refactor the vulnerable code to use secure database interaction methods provided by PHP, such as PDO with bound parameters or MySQLi with prepared statements. In the absence of official patches, consider applying web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting this parameter. Conduct thorough code audits of similar input handling in the application to identify and remediate other injection points. Additionally, monitor logs for suspicious database query patterns and unauthorized access attempts. Restrict database user permissions to the minimum necessary to limit the impact of any successful injection. Finally, maintain regular backups of the database to enable recovery in case of data tampering or loss.
