CVE-2025-9009 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Online Tour and Travel Management System, specifically within an unspecified function in the /admin/email_setup.php file. The vulnerability arises from improper sanitization or validation of the 'Name' parameter, which can be manipulated by an attacker to inject malicious SQL commands. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL queries against the backend database without any user interaction or privileges. The CVSS 4.0 base score is 6.9, indicating a medium severity level. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The vulnerability impacts confidentiality, integrity, and availability to a limited extent (VC:L, VI:L, VA:L), and the scope remains unchanged (SC:N). Exploitation could lead to unauthorized data access, data modification, or disruption of service within the affected system. Although no public exploits are currently known in the wild, the vulnerability details have been disclosed publicly, increasing the risk of exploitation by threat actors. The lack of available patches or updates from the vendor further exacerbates the risk for users of this software version.

For European organizations using the itsourcecode Online Tour and Travel Management System 1.0, this vulnerability poses a significant risk. Tour and travel management systems typically handle sensitive customer data, including personal identification, travel itineraries, payment information, and communication records. Exploitation of this SQL injection flaw could lead to unauthorized disclosure of customer data, resulting in privacy breaches and potential violations of the EU General Data Protection Regulation (GDPR). Additionally, attackers could alter booking information or disrupt system availability, causing operational downtime and reputational damage. Given the remote and unauthenticated nature of the attack, the threat is accessible to a wide range of adversaries, including opportunistic attackers and more sophisticated threat actors. The medium severity rating suggests that while the impact is serious, it may not lead to full system compromise or widespread disruption without additional chained exploits. However, the tourism sector is critical for many European economies, and any compromise could have cascading effects on business continuity and customer trust.

European organizations should immediately assess whether they are using the affected version (1.0) of the itsourcecode Online Tour and Travel Management System. Since no official patches are currently available, organizations should consider the following specific mitigations: 1) Implement Web Application Firewall (WAF) rules tailored to detect and block SQL injection attempts targeting the 'Name' parameter in /admin/email_setup.php. 2) Conduct thorough input validation and sanitization on all user-supplied inputs, especially those related to administrative functions, to prevent injection attacks. 3) Restrict access to the /admin directory by IP whitelisting or VPN-only access to reduce exposure to remote attackers. 4) Monitor database logs and application logs for suspicious queries or anomalies indicative of exploitation attempts. 5) Plan for an upgrade or migration to a patched or alternative system version as soon as a fix becomes available. 6) Educate administrative users about the risks and encourage strong authentication and session management practices to reduce the attack surface. These targeted steps go beyond generic advice by focusing on the specific vulnerable parameter and access points.
