CVE-2025-39587

Comprehensive Technical Analysis of CVE-2025-39587

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-39587 CISA Vulnerability Name: CVE-2025-39587 CVSS Score: 9.3

The vulnerability in question is an SQL Injection flaw in the Stylemix Cost Calculator Builder plugin for WordPress. SQL Injection is a critical vulnerability that allows attackers to execute arbitrary SQL commands on the database, potentially leading to data breaches, data manipulation, and unauthorized access.

Severity Evaluation:

• CVSS Score: 9.3 (Critical)
• Impact: High
• Exploitability: High

The high CVSS score indicates that this vulnerability poses a significant risk. The potential for unauthorized access to sensitive data, data manipulation, and complete compromise of the database makes this a critical issue that requires immediate attention.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unsanitized User Input: Attackers can exploit the vulnerability by injecting malicious SQL code through unsanitized user input fields.
• URL Parameters: Malicious SQL commands can be injected via URL parameters that are directly used in SQL queries.
• Form Fields: Input fields in forms that are not properly sanitized can be used to inject SQL commands.

Exploitation Methods:

• Error-Based SQL Injection: Attackers can use error messages returned by the database to refine their SQL queries.
• Union-Based SQL Injection: Attackers can use the UNION SQL operator to combine the results of two SELECT statements into a single result.
• Blind SQL Injection: Attackers can infer database structure and data by observing the application's behavior without direct error messages.

3. Affected Systems and Software Versions

Affected Software:

• Stylemix Cost Calculator Builder Plugin for WordPress
• Versions Affected: From n/a through 3.2.65

All installations of the Stylemix Cost Calculator Builder plugin up to version 3.2.65 are vulnerable to this SQL Injection issue.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update the Plugin: Ensure that the plugin is updated to a version that addresses this vulnerability. If a patch is not yet available, consider disabling the plugin until a fix is released.
• Input Validation: Implement strict input validation and sanitization for all user inputs.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL Injection.
• Web Application Firewall (WAF): Deploy a WAF to detect and block SQL Injection attempts.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
• Security Training: Provide security training for developers to ensure they are aware of common vulnerabilities and best practices.
• Monitoring: Implement continuous monitoring to detect and respond to any suspicious activities.
