CVE-2025-6917 Overview
A SQL injection vulnerability has been identified in code-projects Online Hotel Booking version 1.0. This vulnerability exists in the /admin/registration.php file, where the uname parameter is not properly sanitized before being used in SQL queries. The flaw allows remote attackers to inject malicious SQL statements, potentially compromising the confidentiality, integrity, and availability of the application's database.
Critical Impact
Remote unauthenticated attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially gain unauthorized access to the hotel booking system's backend.
Affected Products
- Anisha Online Hotel Booking 1.0
- code-projects Online Hotel Booking 1.0

Technical Details for CVE-2025-6917
Vulnerability Analysis
This SQL injection vulnerability stems from improper handling of user-supplied input in the registration functionality of the Online Hotel Booking application. The uname parameter in /admin/registration.php is directly incorporated into SQL queries without adequate sanitization or parameterization. This allows attackers to manipulate the query logic by injecting SQL syntax through the username field.
The vulnerability can be exploited remotely without authentication, making it accessible to any attacker with network access to the application. An exploit for this vulnerability has been publicly disclosed, increasing the risk of active exploitation in the wild.
Root Cause
The root cause of this vulnerability is the lack of input validation and the failure to use parameterized queries or prepared statements when processing the uname parameter. The application directly concatenates user input into SQL statements, creating a classic injection point. This represents a violation of secure coding practices outlined in CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Attack Vector
The attack can be initiated remotely over the network. An attacker sends a crafted HTTP request to the /admin/registration.php endpoint with a malicious SQL payload in the uname parameter. The server processes this request without proper validation, executing the injected SQL commands against the backend database.
The exploitation does not require user interaction or prior authentication to the system. Attackers can craft payloads to enumerate database tables, extract user credentials, modify booking records, or potentially escalate to operating system-level access depending on database configuration.
Technical details and proof-of-concept information have been documented in the GitHub CVE Issue Discussion. Additional vulnerability information is available through VulDB Entry #314410.
Detection Methods for CVE-2025-6917
Indicators of Compromise
- Unusual or malformed requests to /admin/registration.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
- Database error messages appearing in HTTP responses indicating SQL parsing failures
- Unexpected database queries or access patterns in application logs
- Anomalous data extraction or modification activity in database audit logs
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the uname parameter
- Configure intrusion detection systems to alert on SQL injection attack signatures targeting registration endpoints
- Enable verbose logging on the database server to capture unusual query patterns
- Monitor HTTP traffic for requests to /admin/registration.php with encoded or obfuscated payloads
Monitoring Recommendations
- Review web server access logs for repeated requests to /admin/registration.php with varying payloads
- Set up alerting for database errors that may indicate injection attempts
- Implement real-time monitoring of database query patterns for anomalous activity
- Monitor for data exfiltration indicators such as large query result sets or unusual outbound connections
How to Mitigate CVE-2025-6917
Immediate Actions Required
- Restrict access to /admin/registration.php using IP whitelisting or network-level access controls
- Deploy a Web Application Firewall with SQL injection detection rules enabled
- Consider taking the affected registration functionality offline until a patch is available
- Audit database access and credentials for any signs of compromise
Patch Information
No official patch has been released by the vendor at this time. Organizations using the affected software should monitor Code Projects for updates. In the absence of an official fix, implementing the workarounds and detection strategies outlined above is strongly recommended.
For more information about this vulnerability, refer to the VulDB CTI ID #314410 and the VulDB Submission #606285.
Workarounds
- Implement input validation to sanitize the uname parameter, rejecting special characters commonly used in SQL injection
- Modify the application code to use parameterized queries or prepared statements for all database interactions
- Apply the principle of least privilege to database accounts used by the application
- Enable database-level protections such as query whitelisting where supported
- Consider deploying the application behind a reverse proxy with built-in SQL injection protection
