CVE-2024-53502 is a SQL injection vulnerability identified in Seecms version 4.8, located in the SEMCMS_SeoAndTag.php page. The vulnerability arises from insufficient sanitization of user-supplied input before it is incorporated into SQL queries, classified under CWE-89. This flaw enables an attacker with authenticated high-level privileges to inject malicious SQL code, potentially leading to unauthorized data disclosure or modification. The CVSS 3.1 vector indicates network attack vector (AV:N), low attack complexity (AC:L), requiring high privileges (PR:H), no user interaction (UI:N), unchanged scope (S:U), and limited confidentiality and integrity impact (C:L/I:L), with no availability impact (A:N). No known public exploits exist, and no patches have been published as of the vulnerability disclosure date. The vulnerability's exploitation requires authenticated access with elevated privileges, limiting its risk to insider threats or compromised accounts. The affected version is Seecms 4.8, a content management system used in some web environments, though specific market penetration data is limited. The vulnerability could allow attackers to extract sensitive information or alter data within the CMS database, potentially undermining data integrity and confidentiality. Organizations should prioritize monitoring and access control while awaiting official patches.

The impact of CVE-2024-53502 is primarily on the confidentiality and integrity of data managed by Seecms 4.8. An attacker with high-level authenticated access could exploit the SQL injection flaw to read or modify sensitive information stored in the CMS database. This could lead to unauthorized disclosure of user data, manipulation of website content, or corruption of database records. However, the vulnerability does not affect availability, so denial of service is unlikely. Since exploitation requires high privileges and no public exploits are known, the immediate risk is low but could increase if attackers gain privileged access or if exploits are developed. Organizations relying on Seecms 4.8 for critical web content management may face reputational damage, compliance issues, or data breaches if this vulnerability is exploited. The scope is limited to environments where this specific CMS version is deployed, but the impact on those environments could be significant if exploited.

1. Restrict access to the SEMCMS_SeoAndTag.php page to only trusted, authenticated users with necessary privileges. 2. Implement strict input validation and sanitization on all user inputs, especially those interacting with SQL queries, to prevent injection attacks. 3. Employ parameterized queries or prepared statements in the application code to eliminate direct concatenation of user input into SQL commands. 4. Monitor database logs and web application logs for unusual query patterns or errors indicative of SQL injection attempts. 5. Enforce the principle of least privilege for user accounts, ensuring that only essential users have high-level access. 6. Regularly audit user accounts and revoke unnecessary privileges. 7. Stay informed about updates from Seecms developers and apply security patches promptly once available. 8. Consider deploying Web Application Firewalls (WAFs) with SQL injection detection rules to provide an additional layer of defense. 9. Conduct security testing, including automated vulnerability scans and manual penetration testing, focusing on input handling in the CMS. 10. Prepare an incident response plan to quickly address any exploitation attempts.
