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 or validation of the input parameters 'resourcefrom' or 'collectID', which are manipulated by an attacker to inject malicious SQL code. This injection flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring user interaction or authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:H). However, the presence of a high privilege requirement (PR:H) suggests that the attacker must have some level of authenticated access with elevated privileges to exploit this vulnerability. The impact on confidentiality, integrity, and availability is low to limited, as the CVSS vector indicates low impact on these aspects (VC:L/VI:L/VA:L). The vulnerability does not require user interaction and can be exploited remotely, increasing its risk profile. Although no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the likelihood of exploitation attempts. The vulnerability affects a specific version of SeaCMS, a content management system used for website management, particularly in environments that utilize the Cron Task Management Module for scheduled tasks. The lack of available patches at the time of disclosure further elevates the urgency for mitigation. Overall, this vulnerability represents a moderate risk primarily to organizations using the affected SeaCMS version with administrative cron functionalities exposed or accessible remotely.

For European organizations using SeaCMS 13.3.20250820, this vulnerability poses a moderate risk. If exploited, attackers with high-level privileges could manipulate backend databases, potentially leading to unauthorized data access, data corruption, or disruption of scheduled tasks managed by the Cron Task Management Module. This could affect the integrity and availability of web services, potentially causing operational disruptions. Given the medium severity and the requirement for elevated privileges, the threat is more significant for organizations with weak internal access controls or exposed administrative interfaces. Industries such as media, publishing, and any sector relying on SeaCMS for content management could face reputational damage and compliance issues, especially under GDPR regulations if personal data is compromised. The remote exploitability without user interaction increases the attack surface, particularly if administrative endpoints are accessible from the internet or poorly segmented networks.

1. Immediate mitigation should focus on restricting access to the /admin_cron.php endpoint, limiting it to trusted internal networks or VPNs to reduce exposure. 2. Implement strict input validation and sanitization on the 'resourcefrom' and 'collectID' parameters to prevent injection of malicious SQL code. 3. Apply the principle of least privilege by ensuring that only necessary users have high-level privileges required to exploit this vulnerability. 4. Monitor logs for unusual SQL queries or access patterns related to the Cron Task Management Module to detect potential exploitation attempts. 5. If possible, upgrade SeaCMS to a patched version once available or apply vendor-recommended workarounds. 6. Employ Web Application Firewalls (WAFs) with rules targeting SQL injection patterns specific to SeaCMS to provide an additional layer of defense. 7. Conduct regular security audits and penetration testing focusing on administrative modules and input handling to identify similar vulnerabilities proactively.
