CVE-2024-37674 is a Cross Site Scripting (XSS) vulnerability identified in Moodle CMS version 3.10, a widely used open-source learning management system. The vulnerability arises from insufficient sanitization of the 'name' parameter when creating a new activity within the platform. An attacker with at least limited privileges can inject malicious scripts via this parameter, which are then executed in the context of users who view the affected activity. This XSS flaw is classified under CWE-79 and can lead to arbitrary code execution in the victim's browser, potentially enabling session hijacking, credential theft, or further exploitation within the Moodle environment. The CVSS 3.1 base score is 5.5, reflecting a medium severity level due to the requirement of some privileges (PR:L) and user interaction (UI:R). The attack vector is network-based (AV:N), and the scope remains unchanged (S:U). Although no public exploits have been reported yet, the vulnerability poses a tangible risk given Moodle's extensive deployment in educational institutions worldwide. The lack of available patches at the time of publication necessitates immediate attention to mitigate potential exploitation.

The impact of CVE-2024-37674 on organizations using Moodle 3.10 can be significant, particularly in educational and training environments where sensitive student and staff data is stored. Exploitation could allow attackers to execute arbitrary scripts in users' browsers, leading to session hijacking, unauthorized access to user accounts, and potential data leakage. This compromises confidentiality and integrity of user data and can disrupt availability if attackers inject malicious payloads that affect system functionality. The requirement for limited privileges and user interaction reduces the ease of exploitation but does not eliminate risk, especially in environments with many users and frequent activity creation. Institutions relying heavily on Moodle for critical learning operations may face reputational damage, compliance issues, and operational disruptions if this vulnerability is exploited.

To mitigate CVE-2024-37674, organizations should first monitor Moodle's official channels for patches addressing this vulnerability and apply them promptly once available. In the interim, administrators should restrict the ability to create or modify activities to trusted users only, minimizing the attack surface. Implementing Content Security Policy (CSP) headers can help reduce the impact of XSS by restricting script execution sources. Regularly auditing and sanitizing user inputs in custom plugins or themes is advisable to prevent similar issues. Additionally, educating users about the risks of interacting with untrusted content within Moodle can reduce successful exploitation. Network-level protections such as Web Application Firewalls (WAF) configured to detect and block XSS payloads targeting the 'name' parameter may provide temporary defense. Finally, maintaining up-to-date backups and incident response plans will aid in recovery if exploitation occurs.
