EUVD-2025-17539

Comprehensive Technical Analysis of EUVD-2025-17539

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-17539 pertains to an SQL Injection flaw in the MyStyle Custom Product Designer plugin, specifically affecting versions up to and including 3.21.1. The vulnerability allows for Blind SQL Injection, which is a severe type of SQL Injection where the attacker does not receive direct feedback from the database but can infer information through indirect means.

Severity Evaluation:

• Base Score: 9.3 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L

The CVSS score of 9.3 indicates a critical vulnerability. The vector string breakdown is as follows:

• AV:N (Attack Vector: Network): The vulnerability is exploitable over the network.
• AC:L (Attack Complexity: Low): The attack requires low complexity to exploit.
• PR:N (Privileges Required: None): No privileges are required to exploit the vulnerability.
• UI:N (User Interaction: None): No user interaction is required.
• S:C (Scope: Changed): The vulnerability affects a different security scope.
• C:H (Confidentiality: High): There is a high impact on confidentiality.
• I:N (Integrity: None): There is no impact on integrity.
• A:L (Availability: Low): There is a low impact on availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Since the attack vector is network-based, an attacker can exploit this vulnerability remotely without needing physical access to the system.
• Blind SQL Injection: The attacker can send specially crafted SQL queries to the application and infer the database structure and data by analyzing the application's responses over time.

Exploitation Methods:

• Automated Tools: Attackers can use automated tools to send a series of SQL queries designed to extract information from the database.
• Manual Exploitation: Skilled attackers can manually craft SQL queries to exploit the vulnerability, using techniques such as time-based or error-based SQL injection.

3. Affected Systems and Software Versions

Affected Software:

• MyStyle Custom Product Designer plugin for WordPress

Affected Versions:

• All versions from n/a through 3.21.1

Vendor:

• mystyleplatform

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Upgrade to a patched version of the MyStyle Custom Product Designer plugin as soon as it becomes available.
• Temporary Mitigation: Implement a Web Application Firewall (WAF) to filter out malicious SQL injection attempts.

Long-Term Strategies:

• Input Validation: Ensure that all user inputs are properly validated and sanitized.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Regular Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
• Security Training: Provide security training for developers to understand and avoid common vulnerabilities like SQL injection.
