CVE-2025-8984 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Online Tour and Travel Management System. The vulnerability exists in an unspecified function within the file /admin/operations/expense_category.php. Specifically, the issue arises from improper sanitization or validation of the 'expense_name' parameter, which can be manipulated by an attacker to inject malicious SQL code. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits are currently reported in the wild. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is rated low individually but combined can lead to significant data leakage, unauthorized data modification, or denial of service through database corruption or manipulation. Since the affected component is part of the administrative operations module, successful exploitation could compromise sensitive financial or operational data related to expense categories, potentially impacting business processes and financial reporting within organizations using this system.

For European organizations using the itsourcecode Online Tour and Travel Management System version 1.0, this vulnerability poses a tangible risk to the confidentiality and integrity of their financial and operational data. Given the nature of the system—managing tours and travel bookings—compromise could lead to unauthorized access to sensitive customer and business data, financial fraud, or disruption of service availability. This could damage customer trust, lead to regulatory non-compliance (e.g., GDPR violations due to data breaches), and cause financial losses. The remote and unauthenticated nature of the attack vector increases the threat level, especially for organizations that expose the administrative interface to the internet or have weak network segmentation. The medium severity rating suggests that while exploitation is feasible, the impact might be limited to the affected module unless combined with other vulnerabilities or poor security practices. However, the public disclosure of the vulnerability increases the urgency for mitigation to prevent opportunistic attacks.

1. Immediate application of patches or updates from itsourcecode once available is the most effective mitigation. Since no patch links are currently provided, organizations should contact the vendor for remediation guidance. 2. Implement strict input validation and parameterized queries or prepared statements in the expense_category.php file to prevent SQL injection. 3. Restrict access to the /admin/operations/expense_category.php endpoint by IP whitelisting or VPN-only access to reduce exposure. 4. Employ Web Application Firewalls (WAFs) with rules designed to detect and block SQL injection attempts targeting the 'expense_name' parameter. 5. Conduct regular security audits and code reviews focusing on input handling in administrative modules. 6. Monitor logs for unusual database queries or errors that may indicate exploitation attempts. 7. Segregate the database user privileges to limit the impact of any successful injection, ensuring the database account used by the application has the least privileges necessary. 8. Educate system administrators and developers about secure coding practices and the risks of SQL injection.
