CVE-2025-15004 is a SQL injection vulnerability identified in DedeCMS up to version 5.7.118, specifically in the /freelist_main.php file. The vulnerability arises from improper handling of the 'orderby' parameter, which is used to influence the sorting order of database query results. An attacker can manipulate this parameter to inject malicious SQL code, which the backend database executes. This flaw allows remote exploitation without requiring authentication or user interaction, making it accessible over the network with low complexity. The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as indicated by the CVSS vector (VC:L/VI:L/VA:L). Although no known exploits are currently active in the wild, publicly available exploit code increases the likelihood of future exploitation. The vulnerability does not require special privileges, and the attack surface is exposed via a web-accessible PHP script, increasing risk. DedeCMS is a widely used content management system, especially in Chinese-speaking regions, which increases the potential impact on organizations relying on this software for website management. The lack of an official patch link suggests that mitigation may currently rely on manual input validation or upgrading to a fixed version once available.

The SQL injection vulnerability in DedeCMS can lead to unauthorized access to sensitive data, modification or deletion of database records, and potential disruption of website availability. Attackers exploiting this flaw can extract confidential information such as user credentials, content data, or configuration details. Data integrity may be compromised by unauthorized changes to database entries, potentially leading to misinformation or defacement. Availability impacts could arise from crafted queries that cause database errors or resource exhaustion. Organizations running vulnerable DedeCMS instances face risks of data breaches, reputational damage, and operational disruptions. Given the remote and unauthenticated nature of the exploit, attackers can target a wide range of organizations, including government, education, and commercial sectors that use DedeCMS. The presence of public exploit code increases the likelihood of automated scanning and exploitation attempts, raising the urgency for mitigation.

1. Immediately audit all DedeCMS instances to identify those running version 5.7.118 or earlier. 2. Apply official patches or upgrade to a version where this vulnerability is fixed once available. 3. In the absence of a patch, implement strict input validation and sanitization on the 'orderby' parameter to allow only expected values or whitelist sorting options. 4. Employ web application firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the 'orderby' parameter in /freelist_main.php. 5. Monitor web server and database logs for unusual query patterns or repeated attempts to inject SQL code. 6. Restrict database user permissions to the minimum necessary to limit the impact of a successful injection. 7. Conduct regular security assessments and penetration tests focusing on input validation weaknesses. 8. Educate developers and administrators about secure coding practices to prevent similar vulnerabilities in custom modules or future updates.
