CVE-2025-15002 is a SQL injection vulnerability identified in SeaCMS, a content management system, affecting versions 13.0 through 13.3. The vulnerability resides in an unknown function within the PHP file located at js/player/dmplayer/dmku/class/mysqli.class.php. Specifically, the parameters 'page' and 'limit' are improperly sanitized, allowing an attacker to inject malicious SQL code. This injection flaw enables remote attackers to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or deletion. The vulnerability requires no authentication or user interaction, making it easier to exploit remotely over the network. The CVSS 4.0 base score is 6.9, reflecting a medium severity level due to the lack of authentication and user interaction requirements but limited scope and impact compared to critical SQL injection flaws. Although no known exploits have been observed in the wild, the public disclosure of the exploit details increases the likelihood of exploitation attempts. The vulnerability affects the confidentiality, integrity, and availability of the CMS data and possibly the underlying infrastructure if leveraged further.

The SQL injection vulnerability in SeaCMS can have significant impacts on organizations using affected versions. Attackers can exploit this flaw to extract sensitive information such as user credentials, personal data, or proprietary content stored in the CMS database. They may also modify or delete data, leading to data integrity issues or service disruption. In some cases, SQL injection can be leveraged to execute arbitrary commands on the server, potentially leading to full system compromise. The ease of remote exploitation without authentication increases the risk profile, especially for publicly accessible CMS installations. Organizations relying on SeaCMS for content delivery or internal operations may face reputational damage, regulatory penalties, and operational downtime if exploited. The medium severity rating suggests a moderate but non-negligible threat that requires timely remediation to avoid escalation.

To mitigate CVE-2025-15002, organizations should immediately upgrade SeaCMS to a version where this vulnerability is patched once available. In the absence of an official patch, implement strict input validation and sanitization on the 'page' and 'limit' parameters to prevent injection of malicious SQL code. Employ parameterized queries or prepared statements in the affected PHP code to eliminate direct concatenation of user inputs into SQL commands. Restrict access to the CMS backend and related endpoints using network-level controls such as firewalls or VPNs to reduce exposure. Monitor web server and database logs for suspicious query patterns indicative of SQL injection attempts. Additionally, conduct regular security assessments and code reviews focusing on input handling. Deploy Web Application Firewalls (WAFs) with rules to detect and block SQL injection payloads targeting SeaCMS. Finally, maintain up-to-date backups of CMS data to enable recovery in case of data compromise.
