WordPress User Profile Meta Manager plugin <= 1.02 - CSRF naar Privilege Escalation kwetsbaarheid

The CSRF vulnerability in User Profile Meta Manager allows an attacker to craft malicious requests that appear to originate from a legitimate user. By tricking a user into visiting a specially crafted link or page, an attacker can execute actions on their behalf, such as modifying user profile settings, changing roles, or performing other administrative tasks. The impact is significant, as successful exploitation can lead to unauthorized access and control over user accounts and potentially the entire WordPress site, depending on the user's privileges. This is particularly concerning if the affected user has administrative rights.

WordPress sites utilizing the User Profile Meta Manager plugin, particularly those with users having elevated privileges (e.g., administrators, editors). Shared hosting environments are at increased risk, as vulnerabilities in plugins can impact multiple websites hosted on the same server.

• wordpress / composer / npm:

grep -r 'user_profile_meta' /var/www/html/wp-content/plugins/

• generic web:

curl -I https://your-wordpress-site.com/wp-admin/admin-post.php?action=user_profile_meta_update&... # Check for lack of CSRF tokens

The primary mitigation is to upgrade to a patched version of the User Profile Meta Manager plugin as soon as it becomes available. Until then, implement strict input validation on all user profile modification endpoints to prevent malicious data from being processed. Consider implementing CSRF tokens on all sensitive actions within the plugin to ensure that requests are genuinely originating from the user. Web Application Firewalls (WAFs) can be configured to detect and block suspicious CSRF attempts by analyzing request patterns and referrer headers. Regularly review user permissions and access controls to minimize the potential impact of a successful attack.
