CVE-2025-32148

Remediation/Mitigation Strategy: SQL Injection Vulnerability in Daisycon prijsvergelijkers (CVE-2025-32148)

Vulnerability Description:

  • CVE ID: CVE-2025-32148
  • Component: Daisycon Daisycon prijsvergelijkers
  • Description: The Daisycon prijsvergelijkers plugin (versions <= 4.8.4) suffers from an SQL Injection vulnerability. This vulnerability arises due to improper neutralization of special elements used in SQL commands. An attacker can inject malicious SQL code into vulnerable parameters, potentially allowing them to manipulate the database.

Severity:

  • CVSS Score: 8.5 (High) - based on the provided data.
  • Impact: A successful SQL Injection attack can have severe consequences, including:
    • Data Breach: Unauthorized access to sensitive data stored in the database (user credentials, financial information, etc.).
    • Data Modification: Modification or deletion of database records.
    • Privilege Escalation: Potentially gaining administrative access to the application.
    • Denial of Service (DoS): Disrupting the availability of the application.
    • Remote Code Execution (potentially): In some cases, depending on database configuration, SQL injection can lead to remote code execution on the database server.

Known Exploit & Attack Vector:

  • Attack Vector: The specific attack vector (vulnerable parameter(s)) are not explicitly mentioned in the provided data. However, SQL injection vulnerabilities commonly occur in:

    • URL Parameters: Data passed through the URL (e.g., example.com/page.php?id=1).
    • Form Fields: Data submitted through HTML forms.
    • Cookies: Data stored in the user’s browser.
    • API Endpoints: Data passed to the server through API requests (JSON, XML, etc.)

  • Exploit: An attacker would need to identify the vulnerable parameter(s) being used in SQL queries. They would then craft malicious SQL code and inject it into those parameters. For example, a simple injection might look like this in a URL parameter: example.com/page.php?id=1' OR '1'='1 which could bypass authentication, or reveal data. More sophisticated injections could be used to modify data, execute code, or even gain access to the underlying operating system depending on database permissions and configurations. Remediation/Mitigation Strategy:

  1. Immediate Action: Upgrade to a Patched Version:

    • The most effective solution is to upgrade the Daisycon prijsvergelijkers plugin to a version higher than 4.8.4, assuming that a patch has been released that addresses this vulnerability. Check the official Daisycon website or the WordPress plugin repository for the latest version. This is the highest priority.

  2. If Upgrade is Not Immediately Possible (Temporary Mitigations):

    • Web Application Firewall (WAF): Implement or configure a WAF (e.g., ModSecurity, Cloudflare, AWS WAF) to detect and block SQL injection attempts. The WAF should have rulesets specifically designed to protect against SQL injection. Ensure the WAF rules are updated regularly. This acts as a first line of defense. Configure rules to look for common SQL injection payloads (e.g., UNION SELECT, ' OR '1'='1, --).

    • Input Validation and Sanitization: While not a replacement for patching, carefully examine the plugin’s code. Identify all input points (URL parameters, form fields, etc.) that are used in SQL queries. Implement strict input validation to:

      • Whitelist allowed characters: Only allow characters that are expected for the specific input.
      • Reject suspicious characters: Reject inputs containing special characters commonly used in SQL injection attacks (e.g., single quotes, double quotes, semicolons, backslashes).
      • Sanitize the input: Properly escape or encode special characters before using the input in an SQL query. Use parameterized queries or prepared statements (see below). Sanitization should happen on the server-side.

    • Least Privilege Principle: Ensure that the database user account used by the Daisycon prijsvergelijkers plugin has only the minimum necessary privileges. It should not have administrative or root privileges. Restrict its access to only the tables and columns that are absolutely required for the plugin to function.

    • Database Monitoring: Implement database monitoring and logging to detect suspicious activity, such as unusual SQL queries or failed login attempts. Set up alerts to notify administrators of any potential attacks.

  3. Long-Term Solution: Secure Coding Practices:

    • Parameterized Queries/Prepared Statements: This is the most effective defense against SQL injection. Use parameterized queries or prepared statements whenever interacting with the database. These techniques treat user input as data, rather than executable code, preventing attackers from injecting malicious SQL. The plugin code should be refactored to use these methods. Example (PHP with PDO):

          $stmt = $pdo->prepare("SELECT * FROM users WHERE username = ? AND password = ?");

      $stmt->execute([$username, $password]); $user = $stmt->fetch();

    • Code Review: Conduct a thorough code review of the Daisycon prijsvergelijkers plugin to identify and fix any other potential security vulnerabilities. Focus on areas where user input is used in SQL queries.

    • Security Audits: Regularly conduct security audits of the plugin to identify and address vulnerabilities proactively. Consider using automated security scanning tools.

    • Stay Updated: Keep the plugin, the WordPress core, and all other plugins and themes up-to-date with the latest security patches. Testing and Verification:

  • After implementing the remediation steps, thoroughly test the plugin to ensure that the SQL injection vulnerability has been successfully mitigated.
  • Use penetration testing tools and techniques to simulate real-world attacks and verify the effectiveness of the security measures.
  • Consider hiring a security expert to conduct a professional security audit.

Reporting:

  • If you discover any additional vulnerabilities or security issues, report them to the Daisycon developers immediately.

Disclaimer: This remediation strategy provides general guidance based on the limited information provided. The specific steps required to remediate the SQL injection vulnerability may vary depending on the plugin’s code and configuration. It is essential to conduct a thorough investigation and implement the appropriate security measures.
