CVE-2024-6457

Comprehensive Technical Analysis of CVE-2024-6457

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-6457

Description: The HUSKY – Products Filter Professional for WooCommerce plugin for WordPress is vulnerable to time-based SQL Injection via the ‘woof_author’ parameter in all versions up to, and including, 1.3.6. This vulnerability arises due to insufficient escaping on the user-supplied parameter and lack of sufficient preparation on the existing SQL query.

CVSS Score: 9.8

Severity Evaluation:

• Critical: A CVSS score of 9.8 indicates a critical vulnerability. The high score is due to the potential for unauthenticated attackers to execute arbitrary SQL queries, leading to the extraction of sensitive information from the database.
• Impact: The vulnerability can result in the compromise of database integrity, confidentiality, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit this vulnerability without needing to authenticate, making it a high-risk vector.
• Time-Based SQL Injection: The attacker can inject SQL queries that cause a delay in the database response, allowing them to infer information based on the time it takes for the query to execute.

Exploitation Methods:

• SQL Injection: By manipulating the ‘woof_author’ parameter, attackers can inject malicious SQL code. For example, an attacker might use a payload like ' OR SLEEP(5) -- to cause a delay, confirming the presence of the vulnerability.
• Data Exfiltration: Once the vulnerability is confirmed, attackers can craft more complex SQL queries to extract sensitive data such as user credentials, personal information, and financial data.
