CVE-2025-4204 in Ultimate Auction Pro Plugin
Summary
by MITRE • 05/02/2025
The Ultimate Auction Pro plugin for WordPress is vulnerable to SQL Injection via the ‘auction_id’ parameter in all versions up to, and including, 1.5.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The CVE-2025-4204 vulnerability affects the Ultimate Auction Pro plugin for WordPress, representing a critical SQL injection flaw that has been present in all versions up to and including 1.5.2. This vulnerability stems from inadequate input validation and sanitization within the plugin's handling of the 'auction_id' parameter, creating a significant security risk for WordPress sites that utilize this auction management solution. The flaw allows attackers to manipulate database queries through crafted input, potentially compromising the entire database infrastructure.
The technical implementation of this vulnerability occurs when the plugin processes the 'auction_id' parameter without proper escaping or parameterization of user-supplied data. This creates an environment where malicious actors can inject additional SQL commands into the existing database queries. The vulnerability specifically manifests in the plugin's database interaction layer where the 'auction_id' parameter is directly incorporated into SQL statements without appropriate sanitization measures. According to CWE-89, this represents a classic SQL injection vulnerability where insufficient input validation allows attackers to manipulate the intended SQL query execution flow.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to extract sensitive information from the WordPress database. Unauthenticated attackers can exploit this flaw to access user credentials, personal information, auction data, and potentially other sensitive database content. The lack of proper input sanitization means that even basic SQL injection payloads can compromise the integrity of the database operations. This vulnerability directly aligns with ATT&CK technique T1071.004 for application layer protocol manipulation and T1213.002 for data from information repositories, as it enables unauthorized access to database resources.
Mitigation strategies for CVE-2025-4204 should prioritize immediate patching of the Ultimate Auction Pro plugin to version 1.5.3 or later, which contains the necessary security fixes. System administrators should implement input validation measures at the application level to ensure all user-supplied parameters undergo proper sanitization before database interaction. Database access controls should be reviewed and restricted to minimize potential damage from successful exploitation attempts. Additionally, monitoring database queries and implementing web application firewalls can provide additional layers of protection against SQL injection attacks. The vulnerability demonstrates the critical importance of proper parameterization in database operations and highlights the need for regular security audits of third-party WordPress plugins to maintain overall system security posture.
