CVE-2024-39027 identifies an unauthorized SQL injection vulnerability in SeaCMS version 12.9. The flaw exists in the handling of the 'cid' parameter within the endpoint /js/player/dmplayer/dmku/index.php?ac=edit. Due to insufficient input sanitization, attackers can inject malicious SQL code that the backend database executes. This injection enables attackers to retrieve sensitive information stored in the database, such as user credentials, configuration data, or other confidential content. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing its risk profile. The CVSS v3.1 base score of 7.5 reflects a high severity, primarily due to the vulnerability's impact on confidentiality and ease of exploitation over the network. The vulnerability is categorized under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). No patches or official fixes have been linked yet, and no known exploits have been observed in the wild, but the threat remains significant given the commonality of SQL injection attacks and their impact on data confidentiality.

The primary impact of CVE-2024-39027 is the unauthorized disclosure of sensitive database information, which can include user data, credentials, and internal configuration details. This leakage can lead to further attacks such as credential theft, privilege escalation, or lateral movement within the affected organization’s network. Although the vulnerability does not directly compromise data integrity or system availability, the exposure of confidential data can cause severe reputational damage, regulatory penalties, and financial losses. Organizations relying on SeaCMS for content management and web services are at risk of data breaches if the vulnerability is exploited. The ease of remote exploitation without authentication increases the likelihood of attacks, especially if attackers discover vulnerable instances through automated scanning. The absence of known exploits in the wild currently limits immediate widespread impact but does not reduce the urgency for mitigation.

To mitigate CVE-2024-39027, organizations should first monitor for any official patches or updates from SeaCMS and apply them promptly once available. In the absence of patches, implement strict input validation and sanitization on the 'cid' parameter to prevent injection of malicious SQL code. Deploy Web Application Firewalls (WAFs) with rules specifically targeting SQL injection patterns to block exploit attempts. Conduct regular security audits and code reviews focusing on input handling in vulnerable endpoints. Limit database user privileges to the minimum necessary to reduce the impact of potential SQL injection. Enable detailed logging and monitoring of database queries and web application access to detect suspicious activities early. Consider isolating the affected web application components and restricting network access to reduce exposure. Educate development teams on secure coding practices to prevent similar vulnerabilities in future releases.
