CVE-2025-4262 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Online DJ Booking Management System. The vulnerability exists in the /admin/user-search.php file, specifically in the handling of the 'searchdata' parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the underlying database. The vulnerability requires no authentication or user interaction, making it accessible to any remote attacker. The CVSS 4.0 base score is 6.9, indicating a medium severity level. The vector details (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N) suggest that the attack can be performed remotely with low complexity and no privileges or user interaction, but the impact on confidentiality, integrity, and availability is limited. No patches or mitigations have been officially published yet, and there are no known exploits in the wild at this time. However, since the exploit details have been publicly disclosed, the risk of exploitation may increase if no remediation is applied. The vulnerability affects a niche product used for managing DJ bookings, which may be deployed by event management companies or entertainment venues.

For European organizations using the PHPGurukul Online DJ Booking Management System, this vulnerability could lead to unauthorized database access, data leakage, or data manipulation. Although the affected product is specialized, organizations in the entertainment and event management sectors may be impacted, potentially exposing sensitive customer information or booking details. The remote and unauthenticated nature of the vulnerability increases the risk of exploitation, which could disrupt business operations or damage reputation. Given the limited scope of the product, widespread impact across Europe is unlikely, but targeted attacks on organizations using this system could result in operational disruptions and data breaches.

Organizations should immediately audit their use of the PHPGurukul Online DJ Booking Management System to determine if version 1.0 is in use. If so, they should restrict access to the /admin/user-search.php endpoint through network-level controls such as IP whitelisting or VPN access to limit exposure. Implementing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'searchdata' parameter can provide interim protection. Developers or administrators should review and sanitize all user inputs rigorously, employing parameterized queries or prepared statements to prevent SQL injection. Monitoring logs for unusual query patterns or failed injection attempts can help detect exploitation attempts early. Until an official patch is released, consider isolating the affected system from the internet or limiting administrative access to trusted personnel only.
