CVE-2025-2382: Online Banquet Booking System SQLi Flaw

CVE-2025-2382 Overview

A critical SQL Injection vulnerability has been identified in PHPGurukul Online Banquet Booking System version 1.0. The vulnerability exists in the administrative booking search functionality, specifically within the /admin/booking-search.php file. By manipulating the searchdata parameter, an unauthenticated remote attacker can inject malicious SQL queries, potentially compromising the entire database backend including sensitive customer and booking information.

Critical Impact

Successful exploitation allows attackers to extract, modify, or delete database contents remotely without authentication, potentially exposing customer personal data, payment information, and administrative credentials.

Affected Products

• PHPGurukul Online Banquet Booking System 1.0
• Web servers running the vulnerable /admin/booking-search.php endpoint

Technical Details for CVE-2025-2382

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) stems from improper neutralization of special elements used in SQL commands within the booking search functionality. The application fails to properly sanitize user-supplied input in the searchdata parameter before incorporating it into SQL queries executed against the backend database.

The vulnerability is classified under both 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), indicating that the input validation failure enables injection attacks.

The network-accessible attack vector with no authentication requirements makes this vulnerability particularly dangerous for internet-facing deployments. Attackers can exploit this flaw to achieve unauthorized read and write access to the database, potentially extracting sensitive booking records, customer personal information, and administrative credentials.

Root Cause

The root cause of this vulnerability lies in the absence of parameterized queries or prepared statements in the /admin/booking-search.php file. The searchdata parameter value is directly concatenated into SQL query strings without proper input validation or sanitization, allowing attackers to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

The attack can be launched remotely over the network against the vulnerable administrative endpoint. An attacker crafts malicious input containing SQL metacharacters and commands within the searchdata parameter. When the application processes this input, the injected SQL code executes with the privileges of the database user configured for the application.

The exploitation approach typically involves:

1. Identifying the vulnerable /admin/booking-search.php endpoint
2. Crafting payloads with SQL injection techniques (e.g., UNION-based, error-based, or blind injection)
3. Extracting database schema information and sensitive data
4. Potentially escalating to write operations or command execution depending on database configuration

Technical details and proof-of-concept information have been documented in the GitHub CVE Issue Discussion and VulDB #299881.

Detection Methods for CVE-2025-2382

Indicators of Compromise

• Anomalous HTTP requests to /admin/booking-search.php containing SQL syntax characters such as single quotes, double dashes, UNION, SELECT, or OR 1=1 patterns
• Database error messages in application logs indicating malformed SQL queries
• Unusual database query patterns or access to system tables from the web application context
• Unexpected data exfiltration or bulk database reads from the booking system

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in the searchdata parameter
• Configure database activity monitoring to alert on anomalous query patterns or access to sensitive tables
• Enable verbose logging on the /admin/booking-search.php endpoint and monitor for suspicious input patterns
• Deploy intrusion detection signatures for SQL injection attack payloads targeting PHP applications

Monitoring Recommendations

• Monitor HTTP access logs for repeated requests to /admin/booking-search.php with encoded or obfuscated payloads
• Set up alerts for database errors related to SQL syntax in the booking system application logs
• Track and baseline normal database query patterns to identify deviations indicative of injection attacks
• Implement real-time monitoring of outbound database connections that may indicate data exfiltration

How to Mitigate CVE-2025-2382

Immediate Actions Required

• Restrict access to the /admin/ directory by implementing IP-based access controls or additional authentication mechanisms
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules in front of the vulnerable application
• Consider taking the booking search functionality offline until a proper fix is implemented
• Review database user privileges and ensure the application uses a least-privilege database account

Patch Information

At the time of this writing, no official vendor patch has been released for this vulnerability. Organizations using PHPGurukul Online Banquet Booking System 1.0 should monitor the PHP Gurukul website for security updates and patches.

In the absence of an official patch, organizations should implement the workarounds below and consider engaging a security professional to apply a manual code fix using parameterized queries.

Workarounds

• Implement input validation and sanitization for the searchdata parameter using PHP's mysqli_real_escape_string() or equivalent functions as a temporary measure
• Migrate all database queries in the application to use prepared statements with parameterized queries
• Deploy a WAF rule specifically blocking SQL injection patterns in requests to /admin/booking-search.php
• Restrict network access to the administrative interface to trusted IP addresses only

# Example Apache .htaccess configuration to restrict admin access
<Directory "/var/www/html/admin">
    # Restrict to internal IP ranges only
    Require ip 10.0.0.0/8
    Require ip 192.168.0.0/16
    Require ip 172.16.0.0/12
    # Deny all other access
    Require all denied
</Directory>
