CVE-2025-11557 identifies a SQL injection vulnerability in the projectworlds Gate Pass Management System version 1.0, specifically affecting the /add-pass.php endpoint. The vulnerability arises from improper sanitization of the 'fullname' parameter, which is directly incorporated into SQL queries without adequate validation or use of parameterized statements. This allows an unauthenticated remote attacker to inject malicious SQL code, potentially enabling unauthorized data retrieval, modification, or deletion within the underlying database. The vulnerability does not require any privileges or user interaction, making it highly accessible for exploitation. The CVSS 4.0 score of 6.9 reflects a medium severity level, considering the network attack vector, low complexity, and no authentication required, but limited impact on confidentiality, integrity, and availability. Although no known exploits are currently active in the wild, the public disclosure of exploit details increases the likelihood of future attacks. The Gate Pass Management System is typically used to control and log physical access permissions, so exploitation could lead to unauthorized access to sensitive personnel or visitor data, disruption of access control processes, or manipulation of gate pass records. The absence of official patches or vendor advisories necessitates immediate mitigation through secure coding practices and monitoring. This vulnerability highlights the critical need for input validation and the use of prepared statements in web applications handling sensitive access control data.

For European organizations, the exploitation of CVE-2025-11557 could result in unauthorized disclosure of sensitive access control data, including personal information of employees, visitors, or contractors. This compromises confidentiality and may violate data protection regulations such as GDPR, leading to legal and financial repercussions. Integrity of gate pass records could be undermined, allowing attackers to forge or alter access permissions, potentially facilitating physical security breaches. Availability impacts may arise if attackers manipulate database queries to disrupt the gate pass system, causing operational delays or denial of service in physical access management. Organizations relying on this system for critical infrastructure or high-security environments face elevated risks of physical security compromise. The medium severity rating suggests a moderate but tangible threat that requires prompt attention to prevent escalation. The public disclosure of exploit details increases the risk of opportunistic attacks, especially targeting organizations with limited cybersecurity maturity or lacking timely patch management processes.

1. Immediately implement input validation and sanitization on the 'fullname' parameter to reject or neutralize malicious SQL syntax. 2. Refactor the /add-pass.php code to use parameterized queries or prepared statements to prevent SQL injection. 3. Conduct a comprehensive code review of the entire Gate Pass Management System to identify and remediate similar injection flaws. 4. Deploy Web Application Firewalls (WAF) with custom rules to detect and block SQL injection attempts targeting the vulnerable endpoint. 5. Monitor application logs and database activity for unusual queries or access patterns indicative of exploitation attempts. 6. Restrict database user permissions to the minimum necessary to limit the impact of potential injection attacks. 7. If possible, isolate the Gate Pass Management System network segment to reduce exposure to external threats. 8. Engage with the vendor or community to obtain or develop official patches or updates addressing this vulnerability. 9. Educate system administrators and developers on secure coding practices and the importance of input validation. 10. Prepare an incident response plan specific to potential exploitation scenarios involving physical access control systems.
