CVE-2025-9154 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Online Tour and Travel Management System. The flaw exists in the processing of the 'email' parameter within the /user/page-login.php file. Specifically, the application fails to properly sanitize or validate the input passed through this parameter, allowing an attacker to inject malicious SQL code. This injection can be executed remotely without requiring authentication or user interaction, making exploitation relatively straightforward. The vulnerability could allow an attacker to manipulate backend database queries, potentially leading to unauthorized data disclosure, data modification, or even full compromise of the database. The CVSS 4.0 base score of 6.9 (medium severity) reflects the network attack vector, low attack complexity, no privileges or user interaction required, but with limited impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the public availability of exploit code increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is a niche online tour and travel management system, likely used by small to medium-sized travel agencies or related businesses. The lack of patches or vendor mitigation guidance at this time further elevates the risk for users of this software.

For European organizations, particularly those in the travel and tourism sector using the itsourcecode Online Tour and Travel Management System version 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive customer data such as personal identification and booking information, potentially violating GDPR requirements and resulting in legal and financial penalties. Data integrity could also be compromised, affecting booking accuracy and operational reliability. Additionally, attackers could leverage the vulnerability to gain deeper access into internal systems if the database is interconnected with other enterprise applications. The remote and unauthenticated nature of the attack vector means that organizations face a high risk of automated or targeted attacks, especially as exploit code is publicly available. This could disrupt business continuity and damage customer trust. Given the tourism sector's importance in Europe and the sensitivity of personal data handled, the impact extends beyond technical damage to reputational and regulatory consequences.

Organizations using the affected version should immediately undertake the following specific actions: 1) Conduct an inventory to identify any deployments of itsourcecode Online Tour and Travel Management System version 1.0. 2) If possible, upgrade to a patched or newer version once available from the vendor; if no patch exists, consider migrating to alternative, more secure solutions. 3) Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'email' parameter on /user/page-login.php. 4) Employ input validation and parameterized queries or prepared statements in the application code to prevent injection, if source code access and modification is feasible. 5) Monitor logs for suspicious activity related to login attempts or unusual database errors that may indicate exploitation attempts. 6) Restrict database user permissions to the minimum necessary to limit the impact of a successful injection. 7) Ensure regular backups of the database are maintained and tested for restoration to mitigate data loss risks. 8) Educate IT and security teams about this specific vulnerability and the importance of rapid response to any alerts.
