CVE-2025-11076 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Learning Management System (LMS). The vulnerability exists in the /admin/edit_teacher.php file, specifically through manipulation of the 'department' argument. This flaw allows an unauthenticated remote attacker to inject malicious SQL code into the backend database queries. The injection can lead to unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the LMS data. The vulnerability does not require any authentication or user interaction, making it easily exploitable remotely. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low complexity, no privileges required, and no user interaction needed. The impact on confidentiality, integrity, and availability is rated as low individually, but collectively these can lead to significant damage depending on the data exposed or altered. Although no public exploits are currently known in the wild, the exploit code has been made public, increasing the risk of exploitation. The lack of available patches or mitigations from the vendor further elevates the threat. This vulnerability is critical for organizations relying on Campcodes LMS 1.0 for managing educational content and user data, as attackers could leverage this flaw to extract sensitive information such as teacher records, student data, or administrative credentials, or to disrupt LMS operations.

For European organizations using Campcodes Online Learning Management System version 1.0, this vulnerability poses a significant risk to the security and privacy of educational data. Exploitation could lead to unauthorized disclosure of personal data of students and staff, violating GDPR requirements and potentially resulting in regulatory penalties. Integrity of educational records could be compromised, affecting academic outcomes and trust in the institution. Availability impacts could disrupt learning activities, especially in remote or hybrid education setups that depend heavily on LMS platforms. Given the remote exploitation capability without authentication, attackers could target multiple institutions en masse, leading to widespread data breaches or service outages. The medium severity score indicates a moderate but tangible risk that requires prompt attention to avoid escalation. The public availability of exploit code increases the likelihood of opportunistic attacks, particularly from cybercriminals or hacktivists targeting educational institutions in Europe.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include: 1) Restricting access to the /admin/edit_teacher.php endpoint via network-level controls such as IP whitelisting or VPN-only access to administrative interfaces. 2) Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting the 'department' parameter. 3) Conducting thorough input validation and sanitization on all parameters, especially those used in SQL queries, to prevent injection attacks. 4) Monitoring logs for suspicious activity related to the vulnerable endpoint and unusual database query patterns. 5) Segregating the LMS database with least privilege principles to limit the damage in case of compromise. 6) Planning and testing an upgrade or patch deployment as soon as the vendor releases a fix. 7) Educating administrative users about the risks and signs of exploitation attempts. These targeted mitigations go beyond generic advice by focusing on access restrictions, proactive detection, and immediate containment strategies tailored to this specific vulnerability.
