CVE-2025-11399 Overview
A SQL injection vulnerability has been identified in SourceCodester Hotel and Lodge Management System version 1.0. This vulnerability affects the /pages/save_room.php file, where improper handling of the floorno argument allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely by authenticated users, potentially compromising the confidentiality, integrity, and availability of the underlying database.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to read, modify, or delete sensitive database information including guest records, booking data, and administrative credentials.

Technical Details for CVE-2025-11399
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) exists in the /pages/save_room.php endpoint of the Hotel and Lodge Management System. The application fails to properly sanitize user-supplied input in the floorno parameter before incorporating it into SQL queries. This allows authenticated attackers to manipulate the database query structure and execute arbitrary SQL commands.
The vulnerability also falls under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating a fundamental failure in input validation that could enable broader injection attacks. The exploit has been disclosed publicly, increasing the urgency for organizations running this software to implement protective measures.
Root Cause
The root cause of this vulnerability is insufficient input validation and the lack of parameterized queries or prepared statements in the save_room.php file. The floorno parameter is directly concatenated into SQL query strings without proper sanitization or escaping, allowing attackers to break out of the intended query context and inject malicious SQL commands.
Attack Vector
The attack can be executed remotely over the network by any authenticated user with access to the room management functionality. An attacker would craft a malicious request to /pages/save_room.php containing SQL injection payloads in the floorno parameter.
The exploitation flow typically involves:
- Authenticating to the Hotel and Lodge Management System with valid credentials
- Navigating to or directly requesting the /pages/save_room.php endpoint
- Injecting SQL payloads through the floorno parameter to extract data, modify records, or escalate privileges within the database
For technical details on the exploitation methodology, refer to the GitHub Issue Discussion where the vulnerability was publicly disclosed.
Detection Methods for CVE-2025-11399
Indicators of Compromise
- Anomalous HTTP requests to /pages/save_room.php containing SQL metacharacters such as single quotes, semicolons, or UNION keywords in the floorno parameter
- Database error messages in application logs indicating malformed SQL queries
- Unexpected database queries or data access patterns originating from the web application
- Evidence of data exfiltration or unauthorized modifications to room, booking, or user tables
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to /pages/save_room.php
- Implement application-level logging to capture all requests with their full parameters for forensic analysis
- Configure database activity monitoring to alert on suspicious query patterns such as UNION SELECT, OR 1=1, or attempts to access system tables
- Use intrusion detection systems with signatures for common SQL injection attack patterns
Monitoring Recommendations
- Monitor HTTP access logs for repeated requests to /pages/save_room.php with varying floorno values that contain non-numeric characters
- Set up alerts for database errors that may indicate failed injection attempts
- Track authentication logs for credential compromise following successful exploitation
- Review database audit logs for unauthorized data access or privilege escalation attempts
How to Mitigate CVE-2025-11399
Immediate Actions Required
- Restrict access to the Hotel and Lodge Management System to trusted networks or VPN-only access until patches are applied
- Implement WAF rules to block requests containing SQL injection patterns in the floorno parameter
- Disable or restrict access to the /pages/save_room.php functionality if it is not business-critical
- Review database permissions to ensure the application uses a least-privilege database account
- Back up the database to enable recovery in case of data manipulation
Patch Information
No official patch has been released by the vendor at the time of this publication. Organizations using this software should monitor the SourceCodester website for security updates. Given the open-source nature of this project, organizations may need to implement custom fixes or consider alternative solutions.
For tracking and additional context, refer to VulDB #327336.
Workarounds
- Modify the save_room.php source code to implement prepared statements or parameterized queries for the floorno parameter
- Add input validation to ensure floorno only accepts expected numeric values and reject requests with special characters
- Deploy a reverse proxy or WAF with SQL injection detection capabilities in front of the application
- Implement network segmentation to limit access to the management system from untrusted networks
