CVE-2025-11477: Wedding Reservation System SQL Injection

CVE-2025-11477 Overview

A SQL injection vulnerability has been discovered in SourceCodester Wedding Reservation Management System version 1.0. This vulnerability affects unknown code within the file /global.php, where improper handling of the User parameter allows attackers to inject malicious SQL statements. The attack can be launched remotely without authentication, and the exploit has been publicly disclosed, increasing the risk of active exploitation in the wild.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to manipulate database queries, potentially leading to unauthorized data access, data modification, or complete database compromise.

Affected Products

• Janobe Wedding Reservation Management System 1.0
• SourceCodester Wedding Reservation Management System 1.0

Technical Details for CVE-2025-11477

Vulnerability Analysis

This vulnerability is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The flaw exists in the /global.php file of the Wedding Reservation Management System, where the User argument is processed without adequate input sanitization or parameterized queries. This allows an attacker to craft malicious input that gets interpreted as SQL commands by the backend database.

The vulnerability can be exploited remotely over the network without requiring any authentication or user interaction. Successful exploitation could allow attackers to read sensitive database contents, modify or delete data, and potentially escalate privileges within the application.

Root Cause

The root cause of this vulnerability stems from improper input validation and the lack of parameterized queries or prepared statements when handling the User parameter in /global.php. User-supplied input is directly concatenated into SQL queries without proper sanitization, escaping, or type checking, allowing specially crafted input to alter the intended SQL command structure.

Attack Vector

The attack vector is network-based, requiring no authentication or privileges. An attacker can send a specially crafted HTTP request containing malicious SQL syntax within the User parameter to the /global.php endpoint. The vulnerable code processes this input directly in database queries, allowing the attacker to:

1. Extract sensitive information from the database through UNION-based or error-based injection techniques
2. Bypass authentication mechanisms by manipulating login queries
3. Modify or delete database records
4. Potentially execute administrative operations on the database server

The vulnerability mechanism involves insufficient input sanitization where the User parameter value is incorporated into SQL queries without proper validation. Attackers can append SQL operators and commands (such as ' OR '1'='1, '; DROP TABLE users;--, or UNION SELECT statements) to manipulate query logic.

Detection Methods for CVE-2025-11477

Indicators of Compromise

• Unusual or malformed requests to /global.php containing SQL syntax characters such as single quotes, semicolons, double dashes, or UNION keywords in the User parameter
• Database error messages appearing in application responses or logs indicating SQL syntax errors
• Unexpected database query patterns or increased database load from the web application
• Evidence of data exfiltration or unauthorized database modifications in audit logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the User parameter
• Implement application-level logging to capture all requests to /global.php and flag those containing suspicious characters or SQL keywords
• Configure database activity monitoring to alert on anomalous query patterns or unauthorized data access attempts
• Use intrusion detection systems (IDS) with signatures for common SQL injection payloads

Monitoring Recommendations

• Monitor web server access logs for repeated requests to /global.php with varying User parameter values, which may indicate automated exploitation attempts
• Set up alerts for database errors related to SQL syntax in application error logs
• Track database query execution times and patterns for anomalies that could indicate injection-based data extraction
• Review authentication logs for successful logins that bypass normal authentication flow

How to Mitigate CVE-2025-11477

Immediate Actions Required

• Restrict access to the Wedding Reservation Management System to trusted networks or IP addresses until a patch is available
• Implement Web Application Firewall rules to block requests containing SQL injection patterns in the User parameter
• Consider temporarily disabling or removing the /global.php file if it is not essential for application functionality
• Review database user permissions and apply the principle of least privilege to limit potential damage from exploitation

Patch Information

As of the last update on October 9, 2025, no official vendor patch has been released for this vulnerability. Organizations should monitor SourceCodester and vendor channels for security updates. Given that this is an open-source application from SourceCodester, users may need to implement their own code fixes or consider alternative solutions.

For tracking and updates, refer to the VulDB entry #327595 and the SourceCodester website.

Workarounds

• Implement input validation at the application level to sanitize the User parameter, rejecting or escaping special SQL characters before processing
• Modify the vulnerable code in /global.php to use parameterized queries or prepared statements instead of string concatenation for database queries
• Deploy a reverse proxy with request filtering capabilities to inspect and sanitize incoming requests before they reach the application
• Apply network segmentation to isolate the affected system and limit lateral movement in case of compromise
