CVE-2025-11474 is a SQL Injection vulnerability identified in version 1.0 of the SourceCodester Hotel and Lodge Management System, specifically in the /edit_booking.php endpoint. The vulnerability arises from improper sanitization of the 'Name' parameter, which allows an attacker to inject arbitrary SQL commands remotely without authentication or user interaction. This injection flaw can be exploited to manipulate backend database queries, potentially leading to unauthorized data access, modification, or deletion. The vulnerability has a CVSS 4.0 base score of 5.3, reflecting medium severity due to its remote exploitability and lack of required privileges, but limited impact scope and partial impact on confidentiality, integrity, and availability. Although no active exploits have been observed in the wild, the public disclosure of exploit code increases the likelihood of exploitation attempts. The attack complexity is low, and no user interaction is needed, making it a viable threat vector for attackers targeting hospitality management systems. The vulnerability affects only version 1.0 of the software, and no official patches have been linked yet. The lack of proper input validation and use of unsafe SQL query construction are the root causes. This vulnerability could be leveraged to extract sensitive booking data, alter reservation details, or disrupt hotel operations, impacting business continuity and customer trust.

European organizations using SourceCodester Hotel and Lodge Management System 1.0, particularly in the hospitality and lodging sectors, face risks including unauthorized disclosure of customer and booking information, data tampering, and potential service disruption. Confidentiality could be compromised by attackers extracting sensitive personal and payment data stored in the database. Integrity risks include unauthorized modification or deletion of booking records, which could lead to operational confusion and financial loss. Availability might be impacted if attackers execute destructive SQL commands or cause database errors. Given the remote exploitability without authentication, attackers can launch attacks from anywhere, increasing exposure. The medium severity suggests moderate but tangible risks, especially for organizations lacking compensating controls. The public availability of exploit code raises the urgency for mitigation to prevent exploitation by opportunistic attackers. The impact is amplified in countries with high tourism volumes and reliance on digital booking systems, where disruptions could affect reputation and regulatory compliance with data protection laws such as GDPR.

To mitigate CVE-2025-11474, organizations should immediately implement strict input validation and sanitization on the 'Name' parameter in /edit_booking.php to prevent injection of malicious SQL code. Employ parameterized queries or prepared statements to ensure that user input cannot alter SQL command structure. Conduct a thorough code review of all database interaction points to identify and remediate similar injection risks. If patches become available from the vendor, apply them promptly. In the absence of official patches, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the vulnerable endpoint. Monitor database logs and application behavior for unusual queries or errors indicative of exploitation attempts. Restrict database user permissions to the minimum necessary to limit the impact of any successful injection. Regularly back up databases to enable recovery in case of data corruption or deletion. Finally, raise awareness among IT and security teams about this vulnerability and ensure incident response plans include scenarios involving SQL injection attacks.
