CVE-2025-14211 identifies a SQL injection vulnerability in version 1.0 of the projectworlds Advanced Library Management System, specifically within the /delete_book.php script. The vulnerability arises from improper sanitization of the book_id parameter, which is directly used in SQL queries without adequate validation or parameterization. This allows remote attackers to inject malicious SQL code by manipulating the book_id argument, potentially leading to unauthorized data retrieval, modification, or deletion within the underlying database. The attack vector is network-based with no authentication or user interaction required, making exploitation straightforward once the system is accessible. The vulnerability has a CVSS 4.0 score of 6.9, reflecting medium severity due to limited impact on confidentiality, integrity, and availability, but ease of exploitation. Although no exploits have been observed in the wild, the public availability of exploit code increases the likelihood of future attacks. The Advanced Library Management System is typically deployed in educational and library environments, where sensitive user and inventory data may be stored, increasing the potential impact of exploitation. The lack of official patches or vendor advisories necessitates immediate mitigation through secure coding practices and compensating controls.

For European organizations, particularly educational institutions and public libraries using projectworlds Advanced Library Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive data such as user records, borrowing history, and inventory details. Exploitation could lead to data breaches, loss of data integrity, or disruption of library services, impacting operational continuity and user trust. Given the remote, unauthenticated nature of the attack, attackers could leverage this vulnerability to pivot within internal networks or exfiltrate data without detection. The medium severity rating indicates moderate risk, but the public availability of exploit code elevates the urgency for mitigation. Organizations in Europe with limited cybersecurity resources or outdated systems are particularly vulnerable. Additionally, regulatory frameworks like GDPR impose strict data protection requirements, so exploitation could result in legal and financial consequences.

Immediate mitigation should focus on implementing robust input validation and sanitization for the book_id parameter in /delete_book.php. Refactoring the code to use parameterized queries or prepared statements will effectively prevent SQL injection. In the absence of official patches, organizations should conduct thorough code reviews and deploy web application firewalls (WAFs) with rules targeting SQL injection patterns specific to this vulnerability. Network segmentation and restricting external access to the library management system can reduce exposure. Regular monitoring of logs for suspicious database queries or unusual activity is essential. Organizations should also consider isolating the affected system from critical infrastructure until a secure version or patch is available. Engaging with the vendor for updates and applying security best practices for web applications will further reduce risk.
