CVE-2025-2684: PHPGurukul Bank Locker System SQLi Flaw

CVE-2025-2684 Overview

A SQL Injection vulnerability has been discovered in PHPGurukul Bank Locker Management System version 1.0. This issue affects the /search-report-details.php file, where improper handling of the searchinput parameter allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially leading to unauthorized data access, modification, or deletion of sensitive banking and locker information stored in the application's database.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability to extract sensitive customer data, modify locker records, or compromise the underlying database server through the vulnerable search functionality.

Technical Details for CVE-2025-2684

Vulnerability Analysis

This SQL Injection vulnerability exists due to insufficient input validation in the /search-report-details.php endpoint of the Bank Locker Management System. The searchinput parameter accepts user-supplied data that is directly incorporated into SQL queries without proper sanitization or parameterization. This allows attackers to craft malicious input that modifies the intended SQL query structure, enabling them to execute arbitrary database commands.

The vulnerability is particularly concerning as it requires no authentication to exploit. An attacker can simply send crafted HTTP requests to the affected endpoint, manipulating the search functionality to extract database contents, bypass authentication mechanisms, or modify critical locker management records. Given the financial nature of the application, successful exploitation could expose sensitive customer information including personal details, locker assignments, and payment records.

Root Cause

The root cause of this vulnerability is the direct concatenation of user-supplied input from the searchinput parameter into SQL queries without implementing proper input validation, output encoding, or parameterized queries (prepared statements). The application fails to treat user input as untrusted data, allowing SQL metacharacters to break out of the intended query context and inject malicious SQL commands.

Attack Vector

The attack can be initiated remotely over the network. An unauthenticated attacker can craft HTTP requests containing SQL injection payloads in the searchinput parameter of the /search-report-details.php endpoint. By manipulating this parameter with SQL metacharacters and injection payloads, the attacker can alter query logic to extract data, bypass authentication, or perform administrative database operations. Common exploitation techniques include UNION-based injection to extract data from other tables, boolean-based blind injection to infer database contents, and time-based blind injection for environments where direct output is not visible.

Detection Methods for CVE-2025-2684

Indicators of Compromise

• Unusual SQL error messages appearing in application logs or web responses originating from /search-report-details.php
• HTTP requests to /search-report-details.php containing SQL keywords such as UNION, SELECT, DROP, INSERT, or comment sequences (--, /*)
• Database query logs showing unexpected queries or abnormal query patterns from the web application
• Evidence of data exfiltration or unauthorized access to locker management records

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the searchinput parameter
• Monitor application logs for requests containing SQL metacharacters or injection keywords targeting the vulnerable endpoint
• Implement database activity monitoring to detect anomalous query execution patterns
• Use intrusion detection systems (IDS) with SQL injection signature rules

Monitoring Recommendations

• Enable verbose logging for the /search-report-details.php endpoint to capture all incoming requests
• Monitor database server logs for unusual query patterns, failed queries, or unauthorized data access attempts
• Set up alerts for multiple rapid requests to the search functionality from single IP addresses
• Review access logs regularly for suspicious patterns indicating reconnaissance or exploitation attempts

How to Mitigate CVE-2025-2684

Immediate Actions Required

• Restrict access to the /search-report-details.php endpoint until a patch is available or input validation is implemented
• Deploy WAF rules to filter SQL injection attack patterns targeting the vulnerable parameter
• Implement network-level access controls to limit exposure of the vulnerable application
• Review database permissions to ensure the web application uses least-privilege database accounts

Patch Information

No official patch information is currently available from the vendor. Organizations should monitor the PHP Gurukul Security Resource for security updates. For additional technical details regarding this vulnerability, refer to the GitHub CVE Issue Discussion and VulDB #300701.

Workarounds

• Implement server-side input validation to sanitize the searchinput parameter, rejecting or escaping SQL metacharacters
• Modify the affected code to use parameterized queries (prepared statements) instead of string concatenation
• Deploy a reverse proxy or WAF with SQL injection protection rules in front of the application
• Consider taking the search functionality offline temporarily until proper remediation is implemented

# Example .htaccess rule to restrict access to vulnerable endpoint
<Files "search-report-details.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
