CVE-2025-11475: Advanced Library Management SQLi Flaw

CVE-2025-11475 Overview

CVE-2025-11475 is an SQL Injection vulnerability affecting Projectworlds Advanced Library Management System version 1.0. The vulnerability exists in the /view_member.php file, where the user_id parameter is improperly handled, allowing attackers to inject malicious SQL commands. This flaw can be exploited remotely without authentication, potentially enabling unauthorized access to sensitive database information, data manipulation, or system compromise.

Critical Impact
Remote attackers can exploit this SQL Injection vulnerability to extract sensitive data from the database, modify or delete records, and potentially escalate access to the underlying server through advanced SQL injection techniques.

Technical Details for CVE-2025-11475

Vulnerability Analysis

This vulnerability stems from a classic SQL Injection flaw in a PHP web application. The /view_member.php endpoint accepts a user_id parameter that is directly concatenated into SQL queries without proper sanitization or parameterized query usage. The exploit has been publicly disclosed through external tracking systems, increasing the risk of widespread exploitation against unpatched systems.

The vulnerability allows attackers to manipulate database queries by injecting SQL syntax through the user_id parameter. Successful exploitation could lead to unauthorized data access, including sensitive member information stored in the library management system's database.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries (prepared statements) in the /view_member.php file. The application directly incorporates user-supplied input from the user_id parameter into SQL statements, creating a classic CWE-89 (SQL Injection) condition. This represents a fundamental failure to follow secure coding practices for database interactions.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads in the user_id parameter. Since the vulnerable endpoint is remotely accessible, attackers can leverage automated tools to discover and exploit this vulnerability at scale.

The vulnerability is exploited by manipulating the user_id parameter in requests to /view_member.php. An attacker could inject SQL syntax such as UNION-based queries to extract data from other tables, boolean-based blind injection to enumerate database contents, or time-based blind injection techniques. For detailed technical information about this vulnerability, refer to the GitHub Issue Discussion and VulDB entry #327593.

Detection Methods for CVE-2025-11475

Indicators of Compromise

HTTP requests to /view_member.php containing SQL keywords such as UNION, SELECT, OR 1=1, or comment sequences (--, #)
Unusual database query patterns or errors in application logs
Unexpected data access patterns or bulk data retrieval from member tables
Web application firewall (WAF) alerts for SQL injection attempts targeting the vulnerable endpoint

Detection Strategies

Deploy web application firewall rules to detect and block SQL injection patterns in the user_id parameter
Monitor HTTP access logs for suspicious requests to /view_member.php with malformed or injection-style parameters
Implement database activity monitoring to detect anomalous query patterns or unauthorized data access
Use intrusion detection systems with signatures for common SQL injection attack patterns

Monitoring Recommendations

Enable detailed logging for the web application and database server to capture potential exploitation attempts
Configure alerting for repeated requests to /view_member.php with varying user_id values that may indicate automated scanning
Monitor database error logs for SQL syntax errors that may indicate injection attempts
Implement real-time security monitoring for the library management system's web interface

How to Mitigate CVE-2025-11475

Immediate Actions Required

Remove or restrict public access to the Advanced Library Management System until patched
Implement web application firewall rules to block SQL injection attempts targeting /view_member.php
Review application logs for evidence of exploitation and assess potential data exposure
Consider taking the application offline if it contains sensitive member data and cannot be immediately secured

Patch Information

As of the last update on 2026-02-24, no official vendor patch has been publicly documented. Organizations using Projectworlds Advanced Library Management System 1.0 should contact the vendor directly for security updates or consider implementing the workarounds listed below. Monitor the VulDB entry for updates on patch availability.

Workarounds

Implement input validation on the user_id parameter to accept only numeric values
Deploy a web application firewall (WAF) with SQL injection detection rules
Modify the application code to use prepared statements (parameterized queries) for all database interactions
Restrict network access to the application to trusted IP ranges until a proper fix is available
