Remediation/Mitigation Strategy for CVE-2025-2676: SQL Injection in PHPGurukul Bank Locker Management System 1.0

This document outlines the strategy to address the critical SQL Injection vulnerability (CVE-2025-2676) found in PHPGurukul Bank Locker Management System 1.0.

1. Vulnerability Description:

  • Vulnerability: SQL Injection
  • Affected Software: PHPGurukul Bank Locker Management System 1.0
  • Affected File: /add-subadmin.php
  • Affected Parameter: sadminusername
  • Description: The application is vulnerable to SQL Injection due to improper sanitization/validation of user-supplied input passed through the sadminusername parameter in the /add-subadmin.php file. An attacker can inject arbitrary SQL code, potentially leading to unauthorized data access, modification, or deletion.

2. Severity:

  • CVSS Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
  • Impact:
    • Confidentiality: High - Sensitive information, including user credentials, financial data, and system configurations, can be exposed.
    • Integrity: High - Data within the database can be modified or deleted, leading to data corruption or loss of service.
    • Availability: High - The database server or the entire application can be rendered unavailable due to malicious queries causing denial-of-service.

3. Known Exploit:

  • An exploit for this vulnerability is publicly available. This significantly increases the risk of exploitation.

4. Remediation Strategy:

The primary goal is to eliminate the SQL Injection vulnerability. The following steps should be taken immediately:

  • A. Code Modification (Recommended):

    • Input Validation: Implement strict input validation on the sadminusername parameter in /add-subadmin.php. Validate that the input matches the expected format (e.g., alphanumeric characters, maximum length). Reject any input that does not conform to the expected format.

    • Parameterized Queries (Prepared Statements): Replace dynamic SQL queries in /add-subadmin.php with parameterized queries (prepared statements). Parameterized queries treat user input as data rather than executable code, preventing SQL Injection attacks. This is the most effective method to prevent SQL injection. Example (using PDO in PHP):

          // Assuming $sadminusername is the unsanitized user input

      // Prepare the SQL statement $stmt = $pdo->prepare(“INSERT INTO subadmins (username) VALUES (:username)”);

      // Bind the parameter $stmt->bindParam(’:username’, $sadminusername);

      // Execute the statement $stmt->execute();

    • Escaping User Input: If parameterized queries are not immediately feasible, properly escape all user-supplied input before including it in SQL queries. Use the appropriate escaping function for the database being used (e.g., mysqli_real_escape_string for MySQL). Note: This is less secure than parameterized queries and should only be used as a temporary measure.

    • Principle of Least Privilege: Ensure that the database user account used by the application has only the necessary privileges to perform its functions. Avoid granting excessive privileges that could be exploited by an attacker.

  • B. Web Application Firewall (WAF) (Temporary Mitigation):

    • Deploy a Web Application Firewall (WAF) and configure it to detect and block SQL Injection attempts targeting the /add-subadmin.php endpoint and the sadminusername parameter. This can provide a temporary layer of protection while code modifications are being implemented. However, a WAF is not a replacement for proper code remediation.
    • Regularly update the WAF’s rule set to ensure it stays effective against the latest attack techniques.

  • C. Upgrade the Application (If Available):

    • Check for an updated version of PHPGurukul Bank Locker Management System that addresses this vulnerability. If a patch or upgrade is available, apply it immediately after thorough testing in a non-production environment.

5. Mitigation Steps:

In addition to remediation, the following mitigation steps should be taken:

  • A. Monitoring and Logging:

    • Enable detailed logging for all database activity. Monitor logs for suspicious patterns that might indicate attempted SQL Injection attacks.
    • Implement alerting mechanisms to notify security personnel of any potential security incidents.

  • B. Security Awareness Training:

    • Provide security awareness training to developers and system administrators on secure coding practices, including how to prevent SQL Injection vulnerabilities.

  • C. Penetration Testing:

    • Conduct regular penetration testing to identify and address security vulnerabilities in the application. Specifically target the /add-subadmin.php endpoint to ensure that the SQL Injection vulnerability has been effectively addressed.

6. Timeline:

  • Immediate (within 24 hours): Deploy WAF rules to block known SQL Injection patterns. Begin code review of /add-subadmin.php
  • Short Term (within 72 hours): Implement parameterized queries or input escaping in /add-subadmin.php.
  • Medium Term (within 1 week): Thoroughly test the fix in a non-production environment. Apply the code changes to the production environment.
  • Long Term (ongoing): Implement security awareness training for developers. Conduct regular penetration testing.

7. Responsibilities:

  • Development Team: Responsible for implementing code modifications to address the SQL Injection vulnerability.
  • Security Team: Responsible for deploying and configuring the WAF, monitoring logs for suspicious activity, conducting penetration testing, and providing security awareness training.
  • System Administrators: Responsible for applying system updates and patches.

8. Verification:

  • After implementing the remediation steps, verify that the SQL Injection vulnerability has been effectively addressed. This can be done through manual testing, automated vulnerability scanning, and penetration testing. Ensure that no user input passed through the sadminusername parameter can be used to inject malicious SQL code.

This remediation/mitigation strategy provides a framework for addressing the SQL Injection vulnerability in PHPGurukul Bank Locker Management System 1.0. It is important to adapt this strategy to the specific environment and requirements of the organization. Regularly review and update this strategy to ensure it remains effective against evolving threats.
