CVE-2024-9711 is a medium severity vulnerability identified in the EKC Tournament Manager WordPress plugin versions prior to 2.2.2. The vulnerability is classified as CWE-352, which corresponds to Cross-Site Request Forgery (CSRF). Specifically, the plugin lacks proper CSRF protections when updating its settings. This absence of CSRF tokens or equivalent verification mechanisms allows an attacker to craft malicious requests that, when executed by an authenticated administrator, can change plugin settings without their consent. The vulnerability requires the attacker to have the victim (an admin user) logged into the WordPress backend and to trick them into visiting a malicious webpage or clicking a crafted link. The CVSS 3.1 base score is 5.4, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N) shows that the attack can be performed remotely over the network with low attack complexity, requires privileges of a logged-in administrator, does not require user interaction beyond the admin visiting a malicious page, and impacts confidentiality and integrity to a limited extent but does not affect availability. No known exploits are currently reported in the wild, and no official patches or updates are linked yet. The vulnerability impacts the integrity and confidentiality of the affected system by allowing unauthorized changes to plugin settings, which could lead to further compromise or misconfiguration of the WordPress site hosting the plugin.

For European organizations using the EKC Tournament Manager plugin on their WordPress sites, this vulnerability poses a risk of unauthorized administrative changes. Such changes could lead to data leakage, unauthorized access escalation, or disruption of tournament management functionalities. Although the direct impact on availability is minimal, the integrity and confidentiality of administrative settings are at risk. This could affect organizations running sports clubs, event management, or community engagement platforms reliant on this plugin. Given that WordPress is widely used across Europe, any organization with administrative users who might be targeted by social engineering or phishing attacks could be vulnerable. The risk is heightened in environments where administrators have broad privileges and where multi-factor authentication or other compensating controls are not enforced. Additionally, compromised settings could be leveraged to inject malicious code or redirect users, potentially damaging organizational reputation and compliance with data protection regulations such as GDPR.

1. Immediate mitigation involves updating the EKC Tournament Manager plugin to version 2.2.2 or later once available, as this version is expected to include CSRF protections. 2. Until an update is applied, restrict administrative access to trusted networks and users to reduce exposure. 3. Implement multi-factor authentication (MFA) for all WordPress admin accounts to reduce the risk of session hijacking or unauthorized access. 4. Educate administrators about the risks of CSRF and the importance of avoiding clicking on suspicious links or visiting untrusted websites while logged into the WordPress admin panel. 5. Employ web application firewalls (WAFs) with rules that detect and block CSRF attack patterns targeting WordPress admin endpoints. 6. Regularly audit plugin settings and WordPress logs for unusual changes or access patterns that could indicate exploitation attempts. 7. Consider isolating the WordPress admin interface behind VPN or IP whitelisting to limit exposure to external threats. These measures combined will reduce the likelihood and impact of exploitation until a patch is applied.
