EUVD-2025-5631

Comprehensive Technical Analysis of EUVD-2025-5631

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability in question is an SQL Injection flaw in the Bitcoin / AltCoin Payment Gateway for WooCommerce plugin. Specifically, it allows for Blind SQL Injection, which is a type of SQL Injection where the attacker does not receive direct feedback from the database but can infer information based on the application's behavior.

Severity Evaluation: The Base Score of 9.3 (CVSS:3.1) indicates a critical severity level. The scoring vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L breaks down as follows:

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

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: An attacker can inject malicious SQL code into the application through input fields that are not properly sanitized.
• Blind SQL Injection: The attacker can infer the structure of the database and extract data by observing the application's behavior over multiple requests.

Exploitation Methods:

• Automated Tools: Attackers can use automated tools to perform Blind SQL Injection attacks, such as sqlmap.
• Manual Exploitation: Skilled attackers can manually craft SQL queries to extract sensitive information, such as user credentials, transaction details, and other confidential data.

3. Affected Systems and Software Versions

Affected Software:

• Bitcoin / AltCoin Payment Gateway for WooCommerce
• Versions: From n/a through 1.7.6

Affected Systems:
