CVE-2025-9426 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Online Tour and Travel Management System. The vulnerability resides in the /package.php file, specifically in the handling of the 'subcatid' parameter. An attacker can manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. This attack can be executed remotely without requiring any authentication or user interaction, making it highly accessible to threat actors. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The vector details show that the attack requires no privileges, no user interaction, and can be performed over the network with low attack complexity. The impact on confidentiality, integrity, and availability is low individually but combined can lead to significant data exposure or manipulation. Although no known exploits are currently active in the wild, the exploit code has been publicly disclosed, increasing the risk of exploitation. The lack of available patches or mitigation from the vendor further elevates the threat. SQL Injection vulnerabilities typically allow attackers to extract sensitive data, modify or delete records, and in some cases escalate privileges or execute arbitrary commands depending on the database backend and system configuration. Given the nature of the affected system—a tour and travel management platform—compromising the database could expose customer personal data, booking details, payment information, and operational data, which are critical for business continuity and regulatory compliance.

For European organizations using the itsourcecode Online Tour and Travel Management System 1.0, this vulnerability poses a significant risk to data confidentiality and integrity. The tourism sector is vital in Europe, and many SMEs and travel agencies rely on such management systems. Exploitation could lead to unauthorized disclosure of personal customer information, including names, contact details, and potentially payment data, which would violate GDPR requirements and result in legal and financial penalties. Additionally, manipulation or deletion of booking and operational data could disrupt business operations, leading to reputational damage and loss of customer trust. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially from opportunistic attackers or automated scanning tools. Even though the CVSS score is medium, the real-world impact could be severe if sensitive personal and financial data is compromised. Furthermore, the absence of patches means organizations must rely on alternative mitigations, increasing operational complexity and risk exposure.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, input validation and parameterized queries should be enforced at the application level to sanitize the 'subcatid' parameter and prevent SQL injection. If source code modification is not feasible, deploying a Web Application Firewall (WAF) with rules specifically targeting SQL injection patterns on the affected endpoint (/package.php) can help block malicious requests. Network-level restrictions should be applied to limit access to the vulnerable system only to trusted IP addresses where possible. Regular monitoring and logging of database queries and web server access logs should be enhanced to detect suspicious activity indicative of injection attempts. Organizations should also conduct thorough security assessments and penetration testing to identify and remediate similar vulnerabilities. Finally, planning for an upgrade or migration to a patched or alternative system version is critical to long-term risk reduction.
