CVE-2025-11469 Overview
A SQL injection vulnerability has been identified in SourceCodester Hotel and Lodge Management System version 1.0. The vulnerability exists in the /pages/save_customer.php file, where improper handling of the Contact parameter allows attackers to inject malicious SQL commands. This flaw can be exploited remotely by authenticated attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.
Critical Impact
Remote attackers with low privileges can exploit this SQL injection vulnerability to extract sensitive customer data, modify database records, or potentially compromise the entire database server through malicious SQL queries injected via the Contact parameter.

Technical Details for CVE-2025-11469
Vulnerability Analysis
This SQL injection vulnerability exists within the customer management functionality of the Hotel and Lodge Management System. The vulnerable endpoint /pages/save_customer.php fails to properly sanitize or parameterize user-supplied input in the Contact argument before incorporating it into SQL queries. This allows attackers to break out of the intended query structure and inject arbitrary SQL commands.
The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The exploit has been made publicly available, increasing the risk of widespread exploitation against unpatched systems.
Root Cause
The root cause of this vulnerability is inadequate input validation and the absence of parameterized queries or prepared statements in the save_customer.php file. When processing the Contact parameter, the application directly concatenates user input into SQL query strings without proper sanitization, escaping, or use of parameterized queries. This fundamental coding flaw allows attackers to manipulate the query logic by injecting SQL metacharacters and commands.
Attack Vector
The attack can be executed remotely over the network by authenticated users with low privileges. An attacker can craft a malicious HTTP request to the /pages/save_customer.php endpoint, embedding SQL injection payloads within the Contact parameter. When the server processes this request, the injected SQL commands are executed against the backend database, potentially allowing the attacker to:
- Extract sensitive customer information including personal details and booking records
- Modify or delete existing database entries
- Enumerate database structure and retrieve credentials
- Potentially escalate access depending on database configuration
The vulnerability is accessible via network requests to the affected PHP endpoint. Technical details and proof-of-concept information are available through the GitHub Issue Discussion and VulDB #327587.
Detection Methods for CVE-2025-11469
Indicators of Compromise
- Unusual HTTP POST requests to /pages/save_customer.php containing SQL syntax characters such as single quotes, semicolons, or SQL keywords in the Contact parameter
- Database error messages in application logs indicating malformed SQL queries
- Unexpected database query patterns or data access attempts in database audit logs
- Web server access logs showing repeated requests to customer management endpoints with suspicious parameter values
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the Contact parameter
- Enable database query logging and monitor for anomalous query structures or syntax errors
- Deploy intrusion detection systems (IDS) with SQL injection signature rules
- Configure application logging to capture and alert on input validation failures
Monitoring Recommendations
- Monitor web application logs for requests to /pages/save_customer.php with unusual Contact parameter values
- Set up alerts for database authentication failures or privilege escalation attempts
- Review database slow query logs for complex or unusual query patterns indicative of SQL injection exploitation
- Implement real-time monitoring of database connections from the web application tier
How to Mitigate CVE-2025-11469
Immediate Actions Required
- Restrict access to the Hotel and Lodge Management System to trusted networks or users only until a patch is available
- Implement input validation and filtering for the Contact parameter at the application or WAF level
- Deploy a Web Application Firewall with SQL injection protection rules in front of the vulnerable application
- Consider taking the affected application offline if it contains sensitive data and cannot be adequately protected
Patch Information
As of the last NVD update on 2025-10-09, no official patch has been released by the vendor. Organizations using this software should contact SourceCodester or the original developer (nikhil-bhalerao) for remediation guidance. In the absence of an official patch, implementing the workarounds below is strongly recommended. Monitor the SourceCodester website and VulDB entry for updates on available fixes.
Workarounds
- Modify the /pages/save_customer.php file to use prepared statements with parameterized queries for all database interactions
- Implement strict input validation on the Contact parameter, allowing only expected characters (digits, spaces, hyphens for phone numbers)
- Deploy a reverse proxy or WAF that filters SQL injection attempts before they reach the application
- Disable or restrict access to the customer save functionality until proper remediation is applied
