CVE-2025-13247 identifies a SQL injection vulnerability in PHPGurukul Tourism Management System version 1.0, specifically within the /admin/user-bookings.php file. The vulnerability arises from improper sanitization of the uid parameter, which is directly used in SQL queries without adequate validation or parameterization. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially enabling unauthorized access to the backend database. The vulnerability does not require any user interaction or privileges, making it highly accessible to attackers. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based with low complexity and no authentication required, but with limited scope and impact on confidentiality, integrity, and availability. The public release of exploit code increases the likelihood of exploitation, although no confirmed active exploitation in the wild has been reported yet. The Tourism Management System is typically deployed by travel agencies and tourism-related businesses, which often handle sensitive customer data such as personal identification and booking details. Exploitation could lead to data leakage, unauthorized data modification, or denial of service conditions. The lack of official patches or updates at the time of publication necessitates immediate mitigation through secure coding practices and access restrictions. The vulnerability highlights the critical need for input validation and use of prepared statements in web applications handling sensitive data.

For European organizations, especially those in the tourism and travel sectors using PHPGurukul Tourism Management System 1.0, this vulnerability poses significant risks. Exploitation can lead to unauthorized disclosure of personal and booking information, violating GDPR and other data protection regulations, potentially resulting in legal penalties and reputational damage. Data integrity could be compromised, allowing attackers to alter booking records or manipulate system data, disrupting business operations. Availability may also be affected if attackers execute queries that degrade database performance or cause crashes. Given the tourism sector's importance in countries like Spain, Italy, France, and Germany, such disruptions could have broader economic impacts. Furthermore, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within affected organizations. The public availability of exploit code increases the urgency for European entities to address this vulnerability promptly to avoid data breaches and operational interruptions.

European organizations should implement immediate mitigations including: 1) Restricting access to the /admin/user-bookings.php endpoint via network segmentation and firewall rules to limit exposure. 2) Applying strict input validation and sanitization on the uid parameter, ensuring only expected data types and formats are accepted. 3) Refactoring the application code to use parameterized queries or prepared statements to prevent SQL injection. 4) Monitoring web application logs for suspicious query patterns or unusual access attempts targeting the uid parameter. 5) Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts against the affected endpoint. 6) Conducting thorough security assessments and penetration testing to identify similar injection points. 7) Engaging with PHPGurukul or community forums to obtain patches or updates as soon as they become available. 8) Educating developers and administrators about secure coding practices and the risks of unsanitized inputs. 9) Implementing database least privilege principles to limit the impact of any successful injection. 10) Preparing incident response plans to quickly address potential exploitation events.
