CVE-2025-2657: Apartment Visitors Management SQL Injection

CVE-2025-2657 Overview

A critical SQL injection vulnerability has been identified in projectworlds Apartment Visitors Management System version 1.0. The vulnerability exists in the /front.php file where improper handling of the rid parameter allows attackers to inject malicious SQL statements. This flaw can be exploited remotely without authentication, potentially enabling unauthorized access to the application's database, data theft, and manipulation of visitor management records.

Critical Impact
Unauthenticated remote attackers can exploit this SQL injection vulnerability to extract sensitive data, bypass authentication mechanisms, and potentially gain unauthorized control over the apartment visitor management database.

Technical Details for CVE-2025-2657

Vulnerability Analysis

This SQL injection vulnerability occurs due to improper input validation in the /front.php file of the Apartment Visitors Management System. The application fails to properly sanitize user-supplied input in the rid parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL statements that are then executed by the underlying database engine.

The vulnerability is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). These weaknesses indicate that the application does not adequately filter or escape special characters in user input before constructing database queries.

Root Cause

The root cause of this vulnerability is the direct concatenation or interpolation of user-controlled input (the rid parameter) into SQL query strings without proper parameterization or input sanitization. The application fails to implement prepared statements or other secure coding practices that would prevent malicious SQL code from being executed.

Attack Vector

The attack can be launched remotely over the network against the /front.php endpoint. An attacker can craft malicious HTTP requests containing SQL injection payloads in the rid parameter. Since no authentication is required to access the vulnerable endpoint, any remote attacker can exploit this flaw.

The manipulation of the rid parameter allows attackers to:

Extract sensitive visitor data from the database
Bypass authentication and authorization controls
Modify or delete database records
Potentially execute administrative operations depending on database permissions

Detection Methods for CVE-2025-2657

Indicators of Compromise

Unusual or malformed HTTP requests to /front.php containing SQL syntax characters (single quotes, semicolons, SQL keywords like UNION, SELECT, OR)
Database error messages appearing in application logs or responses
Unexpected database queries or access patterns in database audit logs
Evidence of data exfiltration or unauthorized data access attempts

Detection Strategies

Implement web application firewall (WAF) rules to detect SQL injection patterns in the rid parameter
Monitor HTTP access logs for requests to /front.php with suspicious query string patterns
Enable database query logging and alert on anomalous query structures
Deploy intrusion detection systems (IDS) with SQL injection signature detection

Monitoring Recommendations

Configure real-time alerting for SQL injection attack patterns targeting /front.php
Review web server access logs regularly for exploitation attempts
Monitor database server logs for unauthorized queries or error conditions
Establish baseline traffic patterns and alert on deviations

How to Mitigate CVE-2025-2657

Immediate Actions Required

Remove or restrict access to the vulnerable /front.php endpoint until a patch is available
Implement input validation to sanitize the rid parameter, allowing only expected input formats
Deploy a web application firewall (WAF) with SQL injection protection rules
Review and audit database permissions to minimize potential damage from successful exploitation

Patch Information

As of the last modification date (2025-05-13), no official vendor patch has been publicly documented. Organizations using projectworlds Apartment Visitors Management System 1.0 should monitor the vendor's official channels for security updates. In the absence of a vendor patch, consider implementing the workarounds listed below or migrating to an alternative solution.

For additional information, see the VulDB advisory and submission record.

Workarounds

Implement prepared statements or parameterized queries in the /front.php file to prevent SQL injection
Add input validation to ensure the rid parameter only accepts expected numeric or alphanumeric values
Restrict network access to the application to trusted IP addresses only
Deploy a web application firewall configured to block SQL injection attempts
