CVE-2025-9926 is a SQL Injection vulnerability identified in version 1.0 of the projectworlds Travel Management System, specifically within an unspecified function in the /viewsubcategory.php file. The vulnerability arises due to improper sanitization or validation of the 't1' parameter, allowing an attacker to inject malicious SQL code. This injection flaw can be exploited remotely without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/PR:N/UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, as attackers can potentially extract sensitive data, modify or delete records, or disrupt service availability. The CVSS score of 6.9 (medium severity) reflects the moderate impact and ease of exploitation, with limited scope and no requirement for privileges or user interaction. Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The absence of patches or mitigation links at this time suggests that affected organizations must implement compensating controls until an official fix is released. Given the nature of travel management systems, which typically store personal and booking information, this vulnerability poses a significant risk to data privacy and operational continuity.

For European organizations using projectworlds Travel Management System 1.0, this vulnerability could lead to unauthorized access to sensitive customer data, including personal identification and travel details, potentially violating GDPR and other data protection regulations. Attackers exploiting this SQL injection could manipulate booking information, causing financial losses and reputational damage. The ability to execute remote, unauthenticated attacks increases the threat level, especially for organizations with internet-facing instances of the affected software. Disruption of service availability could impact customer experience and operational workflows. Additionally, data breaches resulting from this vulnerability could trigger regulatory fines and legal consequences under European data protection laws. The medium severity rating suggests a need for prompt attention, particularly for organizations in the travel and hospitality sectors that rely on this system for critical business functions.

1. Immediate implementation of Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 't1' parameter in /viewsubcategory.php. 2. Conduct thorough input validation and sanitization on all user-supplied data, especially the 't1' parameter, using parameterized queries or prepared statements to prevent injection. 3. Restrict database user privileges to the minimum necessary to limit the impact of a successful injection attack. 4. Monitor application logs and network traffic for unusual query patterns or error messages indicative of SQL injection attempts. 5. Isolate the affected application from critical backend systems until a patch or update is available. 6. Engage with the vendor or project maintainers to obtain or request a security patch and apply it promptly once released. 7. Perform regular security assessments and penetration testing focusing on injection flaws in the Travel Management System. 8. Educate development and operations teams on secure coding practices and the importance of timely vulnerability remediation.
