The vulnerability identified as EUVD-2025-11629 pertains to an SQL Injection flaw in the CHATLIVE plugin, specifically affecting versions from n/a through 2.0.1. SQL Injection is a critical vulnerability that allows attackers to manipulate SQL queries by injecting malicious code into input fields. The Base Score of 9.3, as per CVSS 3.1, indicates a high severity due to the following factors:

• Attack Vector (AV:N): Network, meaning the vulnerability can be exploited remotely.
• Attack Complexity (AC:L): Low, indicating that the attack does not require specialized conditions.
• Privileges Required (PR:N): None, meaning no authentication is needed to exploit the vulnerability.
• User Interaction (UI:N): None, indicating that no user interaction is required.
• Scope (S:C): Changed, meaning the vulnerability can affect resources beyond the security scope managed by the security authority.
• Confidentiality (C:H): High impact on confidentiality.
• Integrity (I:N): No impact on integrity.
• Availability (A:L): Low impact on availability.

2. Potential Attack Vectors and Exploitation Methods

Attackers can exploit this vulnerability by crafting malicious SQL queries and injecting them into input fields processed by the CHATLIVE plugin. Common attack vectors include:

• Form Inputs: Injecting SQL code into form fields such as login forms, search bars, or any other input fields.
• URL Parameters: Manipulating URL parameters that are used in SQL queries.
• Cookies: Injecting SQL code into cookies if they are used in SQL queries.

Exploitation methods may involve:

• Union-Based SQL Injection: Using UNION SQL statements to retrieve data from other tables.
• Error-Based SQL Injection: Inducing errors to gather information about the database structure.
• Blind SQL Injection: Using true/false questions to extract data without direct feedback.

3. Affected Systems and Software Versions

The vulnerability affects the CHATLIVE plugin for WordPress, specifically versions from n/a through 2.0.1. Users of this plugin within the specified version range are at risk.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Update the Plugin: Immediately update the CHATLIVE plugin to a version higher than 2.0.1 if a patched version is available.
• Input Validation: Implement robust input validation and sanitization to ensure that only expected data is processed.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Web Application Firewalls (WAF): Deploy WAFs to detect and block SQL injection attempts.
• Regular Audits: Conduct regular security audits and code reviews to identify and fix vulnerabilities.
• Monitoring: Implement monitoring and logging to detect any suspicious activities related to SQL queries.
