CVE-2025-3315: Apartment Visitor Management SQL Injection

CVE-2025-3315 Overview

A critical SQL Injection vulnerability has been identified in SourceCodester Apartment Visitor Management System version 1.0. The vulnerability exists in the /view-report.php file, where improper handling of the fromdate and todate parameters allows attackers to inject malicious SQL queries. This web application vulnerability can be exploited remotely without authentication, potentially enabling unauthorized access to the underlying database and sensitive visitor management data.

Critical Impact

Remote attackers can exploit this SQL injection flaw to extract, modify, or delete database contents, potentially compromising all visitor records and system configurations stored in the application's database.

Technical Details for CVE-2025-3315

Vulnerability Analysis

This SQL Injection vulnerability (CWE-74: Injection) occurs in the report viewing functionality of the Apartment Visitor Management System. The application fails to properly sanitize user-supplied input in the date range parameters before incorporating them into SQL queries. When users access the /view-report.php endpoint, the fromdate and todate parameters are passed directly to the database query without adequate input validation or parameterized queries.

The vulnerability allows remote attackers to manipulate the SQL query structure by injecting malicious SQL syntax through the date parameters. This can lead to unauthorized data extraction, data manipulation, or in severe cases, complete database compromise. The network-accessible nature of this vulnerability means any attacker with HTTP access to the vulnerable endpoint can attempt exploitation.

Root Cause

The root cause of this vulnerability is improper input validation and the use of unsanitized user input directly in SQL query construction. The application developers failed to implement prepared statements or parameterized queries when processing the fromdate and todate parameters in the /view-report.php file. This classic SQL Injection pattern allows attackers to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft HTTP requests to the /view-report.php endpoint with malicious SQL payloads embedded in the fromdate or todate GET/POST parameters. The exploitation technique typically involves manipulating the date parameter values to include SQL metacharacters and additional query clauses.

Common attack patterns include using UNION-based injection to extract data from other tables, boolean-based blind injection to infer database contents, or time-based blind injection using database-specific delay functions. The publicly disclosed nature of this exploit increases the risk of widespread exploitation against vulnerable installations.

Detection Methods for CVE-2025-3315

Indicators of Compromise

• Unusual SQL syntax patterns in web server logs for /view-report.php requests, particularly in fromdate and todate parameter values
• HTTP requests containing SQL keywords such as UNION, SELECT, OR 1=1, --, or ' in date parameters
• Database error messages in application logs indicating malformed SQL queries
• Unexpected database queries or access patterns originating from the web application

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in HTTP parameters targeting /view-report.php
• Configure intrusion detection systems to alert on suspicious patterns in date parameter values
• Enable detailed logging on database servers to capture and analyze query patterns for anomalies
• Deploy runtime application self-protection (RASP) solutions to detect injection attempts in real-time

Monitoring Recommendations

• Monitor web server access logs for requests to /view-report.php with abnormal parameter lengths or special characters
• Set up alerts for database errors that may indicate failed injection attempts
• Review authentication logs for unauthorized access following potential exploitation
• Implement network traffic analysis to detect data exfiltration patterns following successful SQL injection

How to Mitigate CVE-2025-3315

Immediate Actions Required

• Restrict network access to the Apartment Visitor Management System to trusted IP addresses only
• Disable or restrict access to the /view-report.php endpoint until a patch is applied
• Implement a Web Application Firewall with SQL injection protection rules as an interim measure
• Review database access logs for signs of prior exploitation and assess potential data exposure

Patch Information

As of the last update on 2025-05-14, no official patch has been released by the vendor (oretnom23/SourceCodester). Organizations using this application should monitor SourceCodester for security updates and consider implementing workarounds until an official fix becomes available. Additional vulnerability information can be found at the VulDB entry.

Workarounds

• Apply input validation by implementing server-side filtering to reject any non-date characters in the fromdate and todate parameters
• Modify the application code to use parameterized queries or prepared statements for all database interactions
• Deploy the application behind a reverse proxy with SQL injection filtering capabilities
• Consider replacing the vulnerable reporting functionality with a secure alternative implementation

# Example: Restrict access to vulnerable endpoint via .htaccess
<Files "view-report.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
