CVE-2025-3314: Apartment Visitor Management SQLI Vulnerability

CVE-2025-3314 Overview

A critical SQL injection vulnerability has been identified in SourceCodester Apartment Visitor Management System version 1.0. The vulnerability exists in the /forgotpw.php file, where the secode parameter is not properly sanitized, allowing remote attackers to inject malicious SQL queries. This vulnerability can be exploited without authentication, enabling attackers to manipulate database queries and potentially compromise the entire application and its underlying data.

Critical Impact

Unauthenticated remote attackers can exploit this SQL injection vulnerability to extract sensitive data, bypass authentication mechanisms, or potentially execute arbitrary commands on the database server.

Technical Details for CVE-2025-3314

Vulnerability Analysis

This SQL injection vulnerability occurs in the password recovery functionality of the Apartment Visitor Management System. The /forgotpw.php endpoint accepts a secode parameter that is directly incorporated into SQL queries without proper validation or sanitization. Because this occurs in a password recovery flow, the vulnerability is accessible to unauthenticated users, significantly increasing the risk surface.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where user-controlled input is not properly sanitized before being used in constructed commands or queries.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) in the password recovery functionality. The secode parameter value is directly concatenated into SQL statements, allowing attackers to break out of the intended query structure and inject arbitrary SQL commands.

This is a common vulnerability pattern in PHP applications where developers use string concatenation to build SQL queries rather than utilizing PDO prepared statements or mysqli parameterized queries.

Attack Vector

The attack can be launched remotely over the network without requiring any authentication or user interaction. An attacker simply needs to send a crafted HTTP request to the /forgotpw.php endpoint with a malicious payload in the secode parameter.

The exploitation technique involves injecting SQL metacharacters and additional SQL clauses into the secode parameter. Depending on the database configuration and the specific SQL context, attackers may be able to:

• Extract sensitive data from the database using UNION-based or blind SQL injection techniques
• Bypass authentication by manipulating password recovery logic
• Modify or delete database records
• In some configurations, execute operating system commands through database functions

For technical details on the exploitation methodology, refer to the GitHub CVE Issue Discussion and VulDB #303511.

Detection Methods for CVE-2025-3314

Indicators of Compromise

• Unusual HTTP requests to /forgotpw.php containing SQL metacharacters such as single quotes, double dashes, or UNION keywords in the secode parameter
• Web server logs showing requests with encoded SQL injection payloads targeting the password recovery endpoint
• Database error messages in application logs indicating malformed SQL queries
• Unexpected database queries or access patterns originating from the web application

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to /forgotpw.php
• Implement application-level logging to monitor for suspicious input patterns in the secode parameter
• Configure database activity monitoring to detect unusual query patterns or unauthorized data access
• Use endpoint detection solutions like SentinelOne to identify exploitation attempts and post-exploitation activities

Monitoring Recommendations

• Enable detailed access logging for the web server and specifically monitor requests to /forgotpw.php
• Set up alerts for database errors that may indicate SQL injection attempts
• Monitor for signs of data exfiltration following potential exploitation
• Review authentication logs for anomalous password recovery attempts

How to Mitigate CVE-2025-3314

Immediate Actions Required

• Remove or disable the /forgotpw.php file if the password recovery feature is not critical to operations
• Implement a Web Application Firewall (WAF) with SQL injection protection rules as an interim measure
• Restrict network access to the application to trusted IP addresses if possible
• Review database permissions to limit the application's database user privileges

Patch Information

As of the last NVD update on 2025-05-14, no official patch has been released by the vendor. Organizations using this software should contact SourceCodester for remediation guidance or consider implementing the workarounds below.

For additional vulnerability intelligence, consult VulDB CTI ID #303511.

Workarounds

• Implement input validation to sanitize the secode parameter, rejecting any input containing SQL metacharacters
• Modify the source code to use prepared statements (PDO or mysqli) for all database queries involving user input
• Deploy a reverse proxy or WAF with SQL injection filtering capabilities in front of the application
• Consider replacing the vulnerable application with an alternative solution that follows secure coding practices
