EUVD-2024-47553

Comprehensive Technical Analysis of EUVD-2024-47553

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in the HUSKY – Products Filter Professional for WooCommerce plugin for WordPress (EUVD-2024-47553) is a time-based SQL Injection vulnerability. This type of vulnerability is particularly severe because it allows unauthenticated attackers to manipulate SQL queries by injecting malicious code through the woof_author parameter. The lack of proper escaping and preparation of SQL queries in versions up to and including 1.3.6 exacerbates the risk.

Severity Evaluation:

• CVSS Base Score: 9.8 (Critical)
• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high base score indicates that this vulnerability poses a significant risk. The attack vector (AV:N) is network-based, requiring no user interaction (UI:N) and no privileges (PR:N). The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), making it a critical issue.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated SQL Injection: Attackers can exploit the vulnerability by crafting a malicious HTTP request that includes a specially crafted woof_author parameter. This parameter is not properly sanitized, allowing the injection of SQL commands.
• Time-Based SQL Injection: This method involves injecting SQL commands that cause a delay in the database response, allowing attackers to infer information based on the time it takes for the query to execute.

Exploitation Methods:

• Data Exfiltration: Attackers can extract sensitive information from the database, such as user credentials, personal information, and financial data.
• Database Manipulation: Attackers can modify database entries, leading to data corruption or unauthorized changes.
• Denial of Service (DoS): By injecting malicious SQL commands, attackers can cause the database to become unresponsive, leading to service disruptions.

3. Affected Systems and Software Versions

Affected Software:

• HUSKY – Products Filter Professional for WooCommerce plugin for WordPress
• Versions: All versions up to and including 1.3.6

Affected Systems:

• WordPress Websites: Any WordPress site using the affected plugin versions is at risk.
• WooCommerce Stores: E-commerce sites running WooCommerce with the vulnerable plugin are particularly vulnerable due to the sensitive nature of the data they handle.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update the Plugin: Ensure that the plugin is updated to a version higher than 1.3.6, where the vulnerability has been patched.
• Disable the Plugin: If an update is not immediately available, consider disabling the plugin until a secure version is released.

Long-Term Mitigation:

• Input Validation and Sanitization: Implement robust input validation and sanitization mechanisms to prevent SQL injection attacks.
• Prepared Statements: Use prepared statements and parameterized queries to ensure that SQL commands are properly escaped.
• Web Application Firewalls (WAF): Deploy WAFs to monitor and block malicious traffic, including SQL injection attempts.
• Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate potential security risks.

5. Impact on European Cybersecurity Landscape

The vulnerability in the HUSKY – Products Filter Professional for WooCommerce plugin poses a significant risk to the European cybersecurity landscape, particularly for e-commerce sites. Given the widespread use of WordPress and WooCommerce, the potential for data breaches and financial losses is high. This underscores the importance of timely updates, robust security practices, and proactive threat intelligence sharing within the European cybersecurity community.

6. Technical Details for Security Professionals

Vulnerability Details:

• Vulnerable Parameter: woof_author
• Vulnerable Code Location: plugins.trac.wordpress.org/browser/woocommerce-products-filter/trunk/ext/by_author/index.php#L102
• Exploitation Example:

  ' OR SLEEP(5) --
  

  This example injects a delay of 5 seconds into the SQL query, allowing attackers to confirm the presence of the vulnerability.

Detection and Monitoring:

• Log Analysis: Monitor database logs for unusual query patterns and delays.
• Intrusion Detection Systems (IDS): Implement IDS to detect and alert on SQL injection attempts.
• Security Information and Event Management (SIEM): Use SIEM solutions to correlate and analyze security events, identifying potential SQL injection attacks.

Patch Information:

• Patch Release: Ensure that the plugin is updated to a version higher than 1.3.6.
• Patch Verification: Verify that the updated plugin includes proper input sanitization and prepared statements to mitigate the vulnerability.
