CVE-2025-11071 is a medium-severity SQL injection vulnerability identified in SeaCMS version 13.3.20250820, specifically within the /admin_cron.php file of the Cron Task Management Module. The vulnerability arises from improper sanitization of the 'resourcefrom' or 'collectID' parameters, which are manipulated to inject malicious SQL code. This flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands against the backend database. The vulnerability does not require user interaction and can be exploited over the network without authentication, although the CVSS vector indicates a requirement for high privileges (PR:H), which suggests that some form of elevated access might be necessary to exploit the flaw fully. The impact on confidentiality, integrity, and availability is low to limited, as indicated by the CVSS vector components (VC:L, VI:L, VA:L). The vulnerability is publicly disclosed but currently has no known exploits in the wild. The absence of patches or mitigation links suggests that SeaCMS users must proactively implement defensive measures. SQL injection vulnerabilities can lead to unauthorized data access, data modification, or denial of service, depending on the attacker's goals and database privileges. Given the vulnerability is in a cron task management module, exploitation could potentially disrupt scheduled tasks or automate malicious activities within the CMS environment.

For European organizations using SeaCMS 13.3.20250820, this vulnerability poses a risk of unauthorized database access or manipulation, potentially compromising sensitive content or operational data managed by the CMS. Although the severity is medium and the impact on confidentiality, integrity, and availability is limited, attackers exploiting this flaw could disrupt automated tasks or gain footholds for further attacks. This could lead to data leakage, defacement, or service interruptions affecting business continuity and reputation. Organizations in sectors relying heavily on CMS platforms for content delivery, such as media, education, and government, may face increased risks. Additionally, the remote exploitability without user interaction increases the attack surface, especially if the CMS is exposed to the internet. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as public disclosure often accelerates exploit development.

1. Immediate upgrade: Monitor SeaCMS vendor communications for official patches or updates addressing CVE-2025-11071 and apply them promptly once available. 2. Input validation: Implement strict server-side input validation and sanitization for all parameters, especially 'resourcefrom' and 'collectID', to prevent injection of malicious SQL code. 3. Web Application Firewall (WAF): Deploy a WAF with custom rules to detect and block SQL injection patterns targeting the vulnerable endpoints. 4. Access controls: Restrict access to /admin_cron.php to trusted IP addresses or internal networks only, minimizing exposure to external attackers. 5. Database permissions: Ensure the database user account used by SeaCMS has the least privileges necessary, limiting the potential damage from SQL injection. 6. Monitoring and logging: Enable detailed logging of web requests and database queries to detect anomalous activities indicative of exploitation attempts. 7. Network segmentation: Isolate CMS servers from critical internal systems to contain potential breaches. 8. Incident response readiness: Prepare and test incident response plans to quickly address any exploitation attempts.
