CVE-2025-5248: PHPGurukul Visitor Management SQL Injection

CVE-2025-5248 Overview

A critical SQL Injection vulnerability has been identified in PHPGurukul Company Visitor Management System version 1.0. The vulnerability exists in the /bwdates-reports-details.php file, where improper handling of the fromdate and todate parameters allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, data manipulation, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL Injection vulnerability to extract sensitive visitor data, modify database records, or potentially gain unauthorized access to the underlying system through database-level attacks.

Affected Products

• PHPGurukul Company Visitor Management System 1.0
• Deployments using /bwdates-reports-details.php for date-based report generation
• Any environment running the vulnerable version without input validation patches

Technical Details for CVE-2025-5248

Vulnerability Analysis

This SQL Injection vulnerability stems from insufficient input validation in the date-based report generation functionality. The /bwdates-reports-details.php script accepts user-supplied fromdate and todate parameters and incorporates them directly into SQL queries without proper sanitization or parameterized query usage. This allows attackers to break out of the intended query structure and inject arbitrary SQL commands.

The vulnerability is remotely exploitable without authentication, requiring no user interaction. Successful exploitation can result in unauthorized read access to database contents, modification or deletion of data, and in some configurations, potential command execution at the database server level.

Root Cause

The root cause is an injection vulnerability (CWE-74) in the PHP application's handling of date range parameters. The application fails to implement proper input validation, prepared statements, or parameterized queries when constructing SQL statements. User-controlled input from the fromdate and todate HTTP parameters is concatenated directly into SQL query strings, allowing malicious SQL syntax to be interpreted and executed by the database engine.

Attack Vector

The attack vector is network-based, allowing remote exploitation through crafted HTTP requests to the vulnerable endpoint. An attacker can submit specially crafted date values containing SQL injection payloads through the fromdate or todate parameters in requests to /bwdates-reports-details.php. The application processes these malicious inputs without validation, executing the injected SQL commands against the backend database.

Exploitation techniques may include:

• Union-based injection to extract data from other database tables
• Boolean-based blind injection to enumerate database structure
• Time-based blind injection when direct output is not available
• Error-based injection leveraging verbose database error messages

Detection Methods for CVE-2025-5248

Indicators of Compromise

• HTTP requests to /bwdates-reports-details.php containing SQL syntax in fromdate or todate parameters
• Unusual database query patterns or errors in application logs
• Unexpected data access patterns or bulk data extraction from visitor management tables
• Web server access logs showing encoded SQL injection payloads in query strings

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in HTTP parameters
• Monitor application logs for SQL error messages indicating injection attempts
• Deploy database activity monitoring to identify anomalous query patterns
• Configure intrusion detection systems with signatures for common SQL injection techniques
• Review web server access logs for requests containing SQL keywords in URL parameters

Monitoring Recommendations

• Enable verbose logging on the web application and database servers
• Set up alerts for SQL error patterns in application logs
• Monitor database connections for unusual query volumes or patterns
• Implement real-time log analysis to detect injection attempts
• Track access to /bwdates-reports-details.php for suspicious parameter values

How to Mitigate CVE-2025-5248

Immediate Actions Required

• Restrict access to /bwdates-reports-details.php through web server configuration or firewall rules
• Implement input validation for all date parameters at the application level
• Consider taking the affected functionality offline until a proper fix is applied
• Review database permissions and apply principle of least privilege
• Enable database query logging to monitor for exploitation attempts

Patch Information

At the time of publication, no official patch from PHPGurukul has been documented for this vulnerability. Organizations using the affected software should monitor the PHP Gurukul Homepage for security updates. Additional technical details regarding this vulnerability are available through VulDB #310350 and the GitHub Issue Discussion.

Workarounds

• Implement a Web Application Firewall with SQL injection detection capabilities in front of the application
• Apply server-side input validation to reject any non-date characters in the fromdate and todate parameters
• Modify the vulnerable PHP code to use prepared statements with parameterized queries
• Restrict network access to the application to trusted IP addresses only
• Deploy the application behind a reverse proxy with request filtering enabled

# Example Apache .htaccess configuration to restrict access to vulnerable file
<Files "bwdates-reports-details.php">
    Order deny,allow
    Deny from all
    # Allow only from trusted internal IPs
    Allow from 192.168.1.0/24
</Files>
