CVE-2025-4214 is a SQL Injection vulnerability identified in version 1.0 of the PHPGuruku Online DJ Booking Management System, specifically within the /admin/booking-bwdates-reports-details.php file. The vulnerability arises from improper sanitization or validation of the 'fromdate' parameter, which is used in SQL queries. An attacker can manipulate this parameter remotely without authentication or user interaction to inject malicious SQL code. This injection can lead to unauthorized access to the backend database, potentially allowing attackers to read, modify, or delete sensitive booking data or administrative information. The vulnerability is classified as medium severity with a CVSS 4.0 base score of 6.9, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. Although no known exploits are currently observed in the wild, the public disclosure of the vulnerability increases the risk of exploitation. Other parameters in the same or related scripts may also be vulnerable, indicating a broader issue with input validation in the application. The lack of available patches or vendor advisories suggests that organizations using this system need to implement immediate mitigations to prevent exploitation.

For European organizations using the PHPGuruku Online DJ Booking Management System, this vulnerability could lead to unauthorized data exposure or manipulation of booking records, which may include personal data of clients and financial transaction details. This compromises confidentiality and integrity of data, potentially violating GDPR requirements and leading to legal and reputational consequences. The administrative interface being vulnerable means attackers could gain elevated access to system functions, possibly disrupting service availability or corrupting data. Given the system's niche use in event and DJ booking management, organizations in the entertainment, event management, and hospitality sectors are primarily at risk. The impact is heightened for organizations that rely heavily on this system for operational continuity or store sensitive customer information. Additionally, exploitation could serve as a foothold for further network intrusion if the booking system is integrated with broader IT infrastructure.

1. Immediate mitigation should include restricting access to the /admin/booking-bwdates-reports-details.php endpoint via network-level controls such as IP whitelisting or VPN-only access to limit exposure. 2. Implement Web Application Firewall (WAF) rules specifically targeting SQL injection patterns on the 'fromdate' parameter and other inputs in the booking system. 3. Conduct a thorough code review and input validation audit of all parameters in the affected scripts to identify and remediate similar injection points. 4. If source code access is available, apply parameterized queries or prepared statements to eliminate SQL injection risks. 5. Monitor logs for suspicious query patterns or repeated access attempts to the vulnerable endpoint. 6. Engage with the vendor or community to obtain or develop patches and plan for an update as soon as available. 7. As a longer-term measure, consider migrating to more secure and actively maintained booking management solutions. 8. Ensure regular backups of booking data are maintained and tested for recovery in case of data corruption or loss due to exploitation.
