The vulnerability CVE-2025-11475 affects projectworlds Advanced Library Management System version 1.0, specifically in the /view_member.php script. The issue arises from insufficient input validation and sanitization of the user_id parameter, which is directly used in SQL queries without proper escaping or parameterization. This allows an attacker to craft malicious input that alters the intended SQL command structure, leading to SQL injection. The attack vector is remote network access with no authentication or user interaction required, making it relatively easy to exploit. The CVSS 4.0 base score is 6.9 (medium), reflecting the potential for partial compromise of confidentiality, integrity, and availability of the database. The vulnerability does not affect system components beyond the database scope and does not require elevated privileges to exploit. No official patches have been linked yet, and no known exploits are reported in the wild, but public disclosure increases the likelihood of future exploitation attempts.

Successful exploitation of this SQL injection vulnerability can allow attackers to read sensitive data from the library management system's database, modify or delete records, and potentially escalate their access within the application. This can lead to unauthorized disclosure of member information, manipulation of library records, and disruption of service availability. For organizations relying on this system, such breaches could result in loss of trust, regulatory penalties related to data protection laws, and operational downtime. The impact is particularly significant for educational institutions, public libraries, and organizations managing sensitive user data through this system. Since the vulnerability is remotely exploitable without authentication, the attack surface is broad, increasing the risk of automated scanning and exploitation by opportunistic attackers.

Immediate mitigation should focus on implementing proper input validation and parameterized queries or prepared statements for the user_id parameter in /view_member.php to prevent SQL injection. If source code modification is not immediately feasible, deploying a Web Application Firewall (WAF) with rules to detect and block SQL injection patterns targeting user_id parameters can reduce risk. Organizations should monitor network traffic for suspicious requests targeting this endpoint and review database logs for anomalous queries. It is critical to maintain regular backups of the database to enable recovery in case of data tampering. Vendors and users should track for official patches or updates from projectworlds and apply them promptly once available. Additionally, conducting security audits and penetration testing on the application can help identify and remediate similar injection flaws elsewhere in the system.
