CVE-2025-4214: Phpgurukul Online DJ Booking SQLi Flaw

CVE-2025-4214 Overview

A SQL injection vulnerability has been identified in PHPGurukul Online DJ Booking Management System version 1.0. This critical security flaw exists in the administrative booking reports functionality, specifically within the file /admin/booking-bwdates-reports-details.php. The vulnerability allows remote attackers to inject malicious SQL commands through the fromdate parameter, potentially compromising the underlying database and application integrity.

Critical Impact
Remote unauthenticated attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially achieve further system compromise through the application's database connection.

Technical Details for CVE-2025-4214

Vulnerability Analysis

This SQL injection vulnerability exists in the booking reports functionality of the PHPGurukul Online DJ Booking Management System. The application fails to properly sanitize user-supplied input in the fromdate parameter before incorporating it into SQL queries. This lack of input validation allows attackers to inject arbitrary SQL statements that are then executed by the database server with the same privileges as the application's database user.

The vulnerability is network-exploitable and requires no authentication or user interaction, making it particularly dangerous for publicly accessible installations. The exploit has been publicly disclosed, increasing the risk of widespread exploitation. Additionally, other parameters within the same functionality may be similarly affected.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries or prepared statements in the affected PHP file. The fromdate parameter value is directly concatenated into SQL query strings without proper sanitization or escaping, creating a classic SQL injection attack vector. This is classified under 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 without requiring any authentication. An attacker can manipulate the fromdate parameter in HTTP requests to /admin/booking-bwdates-reports-details.php to inject malicious SQL payloads. These payloads can be crafted to extract database contents, bypass authentication mechanisms, modify data, or potentially execute operating system commands depending on the database configuration and privileges.

The exploitation involves sending crafted HTTP requests to the vulnerable endpoint with SQL injection payloads embedded in the fromdate parameter. Common techniques include UNION-based injection for data extraction, boolean-based blind injection for enumeration, and time-based blind injection when direct output is not visible. For technical details, see the GitHub Issue for CVE.

Detection Methods for CVE-2025-4214

Indicators of Compromise

Unusual SQL error messages appearing in application logs or web server error logs
Unexpected database queries containing SQL keywords like UNION, SELECT, DROP, or INSERT in the context of date parameters
Anomalous access patterns to /admin/booking-bwdates-reports-details.php with suspicious query string parameters
Database audit logs showing unauthorized data access or extraction attempts

Detection Strategies

Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in the fromdate parameter
Implement application-level logging to monitor requests to the vulnerable endpoint for malformed date inputs
Configure database query logging to identify queries with unexpected structure or content
Use intrusion detection systems (IDS) with SQL injection signature detection capabilities

Monitoring Recommendations

Monitor HTTP access logs for requests containing SQL meta-characters (', ", ;, --, /*) in URL parameters targeting the affected PHP file
Set up alerts for database errors that may indicate injection attempts, such as syntax errors in queries
Review database connection logs for unusual query patterns or excessive data retrieval
Implement real-time monitoring of web application traffic for anomalous patterns

How to Mitigate CVE-2025-4214

Immediate Actions Required

Restrict access to the administrative panel /admin/ directory to trusted IP addresses only
Implement Web Application Firewall rules to filter malicious input on the fromdate parameter
Consider temporarily disabling the booking reports functionality until a patch is applied
Audit database access logs for signs of prior exploitation

Patch Information

No official vendor patch has been released at this time. Organizations using PHPGurukul Online DJ Booking Management System 1.0 should monitor the vendor's website and the VulDB entry for security updates. In the absence of an official fix, implementing the workarounds below is strongly recommended.

Workarounds

Apply input validation to sanitize the fromdate parameter, allowing only properly formatted date strings
Modify the affected PHP code to use prepared statements with parameterized queries instead of direct string concatenation
Implement a Web Application Firewall (WAF) with SQL injection protection rules
Restrict network access to the application's administrative interface using IP-based access controls
Consider deploying the application behind a reverse proxy with request filtering capabilities

bash

# Example: Apache .htaccess to restrict admin access by IP
<Directory "/var/www/html/admin">
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
</Directory>
