CVE-2025-9928 is a SQL Injection vulnerability identified in version 1.0 of the projectworlds Travel Management System, specifically within the /viewcategory.php file. The vulnerability arises from improper sanitization or validation of the 't1' parameter, which allows an attacker to manipulate the SQL query executed by the backend database. This flaw can be exploited remotely without requiring any authentication or user interaction, making it highly accessible to attackers. The vulnerability has a CVSS 4.0 base score of 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 impact on confidentiality, integrity, and availability is rated as low to limited (VC:L, VI:L, VA:L), suggesting that while the attacker can potentially extract or modify some data, the overall system impact is somewhat constrained. The exploit code has been publicly released, increasing the risk of exploitation, although no confirmed active exploitation in the wild has been reported yet. The vulnerability does not involve scope changes or security requirements bypass, and no patches or vendor advisories have been linked yet. The root cause is typical of SQL Injection issues where user input is directly embedded into SQL statements without adequate parameterization or escaping, allowing attackers to inject malicious SQL commands that can read, modify, or delete database contents or escalate privileges within the application context.

For European organizations using the projectworlds Travel Management System version 1.0, this vulnerability poses a tangible risk to the confidentiality and integrity of travel-related data, including customer information, booking details, and potentially sensitive travel itineraries. Exploitation could lead to unauthorized data disclosure, data tampering, or disruption of travel management services. Given the remote and unauthenticated nature of the attack, threat actors could leverage this vulnerability to conduct reconnaissance, exfiltrate sensitive data, or prepare for further attacks such as privilege escalation or lateral movement within the network. The public availability of exploit code increases the likelihood of opportunistic attacks, especially against organizations that have not applied mitigations or are unaware of the vulnerability. While the impact on availability is limited, the reputational damage and regulatory consequences (e.g., GDPR violations due to data breaches) could be significant for European entities. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise without additional chained exploits or misconfigurations.

To mitigate CVE-2025-9928, European organizations should immediately audit their deployment of projectworlds Travel Management System version 1.0 and identify any instances of the vulnerable /viewcategory.php endpoint. Since no official patch is currently linked, organizations should implement the following specific mitigations: 1) Apply input validation and sanitization on the 't1' parameter, enforcing strict whitelisting of expected values or using parameterized queries/prepared statements to prevent SQL injection. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 't1' parameter. 3) Conduct code reviews and penetration testing focused on SQL injection vectors within the application. 4) Restrict database user permissions to the minimum necessary to limit the impact of any injection attack. 5) Monitor logs for suspicious query patterns or repeated access attempts to /viewcategory.php with unusual 't1' parameter values. 6) If feasible, isolate the travel management system in a segmented network zone to reduce lateral movement risk. 7) Stay alert for vendor updates or patches and plan for prompt application once available. 8) Educate IT and security teams about this vulnerability and the importance of timely remediation.
