CVE-2025-2678: PHPGurukul Bank Locker System SQLi Flaw

CVE-2025-2678 Overview

A critical SQL injection vulnerability has been identified in PHPGurukul Bank Locker Management System version 1.0. This vulnerability affects the file /changeimage1.php, where improper handling of the editid parameter allows attackers to inject malicious SQL statements. The vulnerability can be exploited remotely without authentication, potentially leading to unauthorized database access, data theft, or manipulation of sensitive banking and locker management information.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability remotely to access, modify, or delete sensitive data in the Bank Locker Management System database, potentially compromising customer financial and personal information.

Affected Products

• PHPGurukul Bank Locker Management System 1.0
• Web applications using vulnerable /changeimage1.php endpoint
• Deployments with network-accessible management interfaces

Technical Details for CVE-2025-2678

Vulnerability Analysis

This SQL injection vulnerability exists in the /changeimage1.php file of PHPGurukul Bank Locker Management System. The application fails to properly sanitize user-supplied input in the editid parameter before incorporating it into SQL queries. This classic injection flaw allows attackers to manipulate database queries by injecting malicious SQL code through the vulnerable parameter.

The vulnerability is network-accessible and requires no authentication or user interaction, making it particularly dangerous for internet-facing installations. The public disclosure of exploit details increases the risk of active exploitation attempts against vulnerable systems.

Root Cause

The root cause of CVE-2025-2678 is the failure to implement proper input validation and parameterized queries in the /changeimage1.php file. The editid parameter is directly concatenated into SQL statements without sanitization, escaping, or the use of prepared statements. This violates secure coding practices and allows user-controlled input to alter the structure and logic of database queries.

The vulnerability is classified under 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).

Attack Vector

The attack vector for this vulnerability is network-based, allowing remote exploitation without any special privileges or user interaction. An attacker can craft malicious HTTP requests to the /changeimage1.php endpoint with a manipulated editid parameter containing SQL injection payloads.

Successful exploitation could enable attackers to bypass authentication mechanisms, extract sensitive customer data including personal and financial information, modify or delete database records, and potentially escalate privileges within the application. The exploit has been publicly disclosed, which increases the likelihood of opportunistic attacks.

Detection Methods for CVE-2025-2678

Indicators of Compromise

• Unusual or malformed HTTP requests targeting /changeimage1.php with suspicious editid parameter values
• SQL error messages in application logs indicating injection attempts (e.g., syntax errors, unexpected query results)
• Database audit logs showing unauthorized SELECT, UPDATE, DELETE, or UNION-based queries
• Access logs revealing automated scanning patterns against PHP endpoints

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the editid parameter
• Implement application-level logging to capture and alert on malformed input to /changeimage1.php
• Configure Intrusion Detection Systems (IDS) with signatures for common SQL injection payloads
• Enable database query logging and monitor for anomalous query patterns or unauthorized data access

Monitoring Recommendations

• Monitor web server access logs for repeated requests to /changeimage1.php with varying editid values
• Set up alerts for database errors related to SQL syntax issues that may indicate injection attempts
• Implement rate limiting on authentication and sensitive endpoints to slow automated attacks
• Review database access patterns for unusual bulk data extraction or modification activities

How to Mitigate CVE-2025-2678

Immediate Actions Required

• Restrict network access to the Bank Locker Management System to trusted IP addresses only
• Implement a Web Application Firewall (WAF) with SQL injection protection rules
• Disable or remove the vulnerable /changeimage1.php file if the image change functionality is not critical
• Conduct a security audit to identify any evidence of prior exploitation
• Back up database contents and implement enhanced monitoring

Patch Information

At the time of this advisory, no official patch has been released by PHPGurukul for this vulnerability. Organizations using Bank Locker Management System 1.0 should monitor the PHPGurukul website for security updates and consider implementing the workarounds described below until an official fix becomes available.

Workarounds

• Modify the /changeimage1.php source code to use parameterized queries (prepared statements) for all database operations involving the editid parameter
• Implement strict input validation to ensure editid only accepts numeric values
• Deploy a reverse proxy or WAF with SQL injection filtering capabilities in front of the application
• Consider taking the application offline or restricting access until proper remediation can be implemented
• Apply PHP security hardening measures including disabling error display and implementing Content Security Policy headers

# Example: Restrict access to changeimage1.php via Apache .htaccess
<Files "changeimage1.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
