CVE-2025-29390

Remediation/Mitigation Strategy: CVE-2025-29390

Vulnerability: SQL Injection in the set_password function within application/controllers/home.php of jerryhanjj ERP 1.0.

Severity: High (CVSS Score: 8.8)

Known Exploit: The vulnerability allows an attacker to inject arbitrary SQL code into the set_password function. This could allow the attacker to:

  • Bypass authentication.
  • Read, modify, or delete sensitive data within the database.
  • Potentially gain full control over the ERP system depending on the database user privileges.

Remediation/Mitigation Steps:

  1. Input Validation and Sanitization:

    • Description: Implement robust input validation and sanitization for all user-supplied input used in the set_password function, specifically the data that will be used in a database query.
    • Implementation:
      • Use parameterized queries (also known as prepared statements) with placeholders for user-supplied data. This prevents the database from interpreting the data as code. This is the preferred method.
      • If parameterized queries are not feasible, thoroughly sanitize user input. Apply escaping functions specific to the database being used (e.g., mysqli_real_escape_string() for MySQL) to escape special characters that could be used in SQL injection attacks.
      • Implement whitelisting of allowed characters and data formats. Reject any input that does not conform to the expected format.

  2. Least Privilege Principle:

    • Description: Ensure the database user account used by the ERP application has only the minimum necessary privileges required for its operation.
    • Implementation:
      • Avoid using database administrator accounts for the application’s database connection.
      • Grant only SELECT, INSERT, UPDATE, and DELETE privileges on the necessary tables. Do not grant CREATE, DROP, or other administrative privileges.

  3. Web Application Firewall (WAF):

    • Description: Deploy a Web Application Firewall (WAF) to detect and block malicious SQL injection attempts.
    • Implementation:
      • Configure the WAF with rules to identify and block common SQL injection patterns.
      • Regularly update the WAF rules to protect against newly discovered attack vectors.

  4. Code Review and Security Audits:

    • Description: Conduct thorough code reviews and security audits of the set_password function and other areas of the application that handle user input.
    • Implementation:
      • Use static analysis tools to identify potential vulnerabilities.
      • Engage security experts to perform penetration testing and vulnerability assessments.

  5. Regular Security Patching:

    • Description: Implement a process for regularly applying security patches and updates to the ERP system and its underlying components (e.g., operating system, web server, database server).
    • Implementation:
      • Monitor security advisories and vulnerability databases for new threats.
      • Test patches in a non-production environment before deploying them to production.

  6. Error Handling:

    • Description: Implement proper error handling to prevent sensitive information from being exposed in error messages.
    • Implementation:
      • Avoid displaying detailed database error messages to users.
      • Log errors to a secure location for analysis by administrators.

  7. Upgrade to a Secure Version:

    • Description: If a patched version of jerryhanjj ERP is available, upgrade to that version immediately. This is the most effective long-term solution.
    • Implementation:
      • Follow the vendor’s instructions for upgrading the ERP system.
      • Thoroughly test the upgraded system to ensure that it functions correctly and that the vulnerability has been resolved.

Priority: High. Due to the severity of the vulnerability and the potential for significant impact, these steps should be implemented as soon as possible.

Testing: After implementing the remediation steps, conduct thorough testing to verify that the vulnerability has been successfully addressed. This should include:

  • Manual testing with various SQL injection payloads.
  • Automated vulnerability scanning.
  • Penetration testing by a qualified security professional.
