CVE-2024-13148: SQL Injection Vulnerability in Yukseloglu Filter B2B Login Platform

This document outlines the remediation and mitigation strategy for CVE-2024-13148, an SQL Injection vulnerability affecting the Yukseloglu Filter B2B Login Platform.

1. Vulnerability Description:

• CVE ID: CVE-2024-13148
• Vulnerability Type: Improper Neutralization of Special Elements used in an SQL Command (‘SQL Injection’)
• Affected Software: Yukseloglu Filter B2B Login Platform versions prior to 16.01.2025

The vulnerability allows an attacker to inject malicious SQL code into database queries. This can be achieved through user-supplied input that is not properly sanitized or validated before being used in a database query. As a result, an attacker can potentially:

• Bypass authentication
• Read sensitive data from the database (including usernames, passwords, customer data, and business-critical information)
• Modify or delete data in the database
• Execute arbitrary commands on the database server (in severe cases)

2. Severity Assessment:

• CVSS v3 Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
  • Explanation: This score indicates a critical vulnerability. It is network-based, requires no user interaction, and allows an unauthenticated attacker to completely compromise the system’s confidentiality, integrity, and availability.

3. Known Exploits:

• While specific exploit details are not provided in the CVE description, SQL Injection is a well-understood and commonly exploited vulnerability. Attackers use various techniques to identify and exploit SQL Injection flaws, including:
  • Error-based SQL Injection: Triggering database errors to reveal information about the database structure and query logic.
  • Union-based SQL Injection: Using the UNION operator to combine the results of the original query with a malicious query to extract data.
  • Blind SQL Injection: Inferring information about the database through the application’s response to different payloads, even without direct error messages.
  • Time-based Blind SQL Injection: Using WAITFOR or similar functions to delay the database response based on the truthiness of a condition, allowing attackers to deduce information bit by bit.

4. Remediation / Mitigation Strategy:

The following steps should be taken to remediate and mitigate CVE-2024-13148:

• Immediate Action: Upgrade Yukseloglu Filter B2B Login Platform: The most effective solution is to upgrade the Yukseloglu Filter B2B Login Platform to version 16.01.2025 or later, which presumably includes a fix for this vulnerability. Apply the upgrade as soon as possible, following the vendor’s instructions.

• Code Review and Remediation (if upgrade is not immediately possible): If an immediate upgrade is not possible, conduct a thorough code review of the B2B Login Platform application, focusing on database interaction points. Look for areas where user-supplied input is used to construct SQL queries. Implement the following best practices:

  • Parameterized Queries (Prepared Statements): Use parameterized queries or prepared statements for all database interactions. This is the most effective way to prevent SQL Injection. Parameterized queries treat user input as data, not as part of the SQL query itself.

  • Input Validation and Sanitization: Validate and sanitize all user input before it is used in any part of the application, including SQL queries. Specifically:

    • Whitelist Validation: Define the allowed characters and formats for each input field and reject any input that does not conform to the defined rules.
    • Escape Special Characters: If parameterized queries are not possible in a particular situation, carefully escape any special characters that could be interpreted as SQL commands (e.g., single quotes, double quotes, backslashes). Use the database’s specific escaping functions or libraries. Note: Escaping alone is often insufficient and parameterized queries are always preferred.

  • Least Privilege Principle: Ensure that the database user account used by the application has only the minimum necessary privileges. Avoid using a database account with dbo or sa permissions.

  • Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) in front of the B2B Login Platform. Configure the WAF to block common SQL Injection attacks. This provides an additional layer of defense, but it should not be considered a substitute for proper coding practices.

• Testing and Validation:

  • Penetration Testing: Conduct penetration testing of the B2B Login Platform after applying the remediation steps. This will help verify that the vulnerability has been successfully addressed.
  • Vulnerability Scanning: Use automated vulnerability scanners to scan the application for SQL Injection vulnerabilities.
  • Regression Testing: Perform regression testing to ensure that the remediation steps have not introduced any new vulnerabilities or broken existing functionality.

• Monitoring and Logging:

  • Enable Detailed Logging: Enable detailed logging of database queries and application errors. This can help detect and investigate potential SQL Injection attacks.
  • Monitor for Suspicious Activity: Monitor the logs for suspicious activity, such as unusual database queries or error messages related to SQL syntax.

• Incident Response Plan:

  • Update Incident Response Plan: Update the incident response plan to include procedures for handling SQL Injection attacks.
  • Train Staff: Train staff on how to identify and respond to SQL Injection attacks.

5. Long-Term Security Measures:

• Secure Development Lifecycle (SDLC): Implement a secure development lifecycle (SDLC) to ensure that security is considered throughout the software development process.
• Regular Security Audits: Conduct regular security audits of the B2B Login Platform and other applications to identify and address potential vulnerabilities.
• Stay Updated on Security Best Practices: Keep up-to-date on the latest security best practices and threats.

6. Communication:

• Inform users of the security update.
• Provide guidance on password resets if data may have been compromised.

By implementing these remediation and mitigation steps, the risk associated with CVE-2024-13148 can be significantly reduced. Remember that security is an ongoing process, and continuous monitoring, testing, and improvement are essential to protecting the B2B Login Platform from SQL Injection and other threats.
