AI-suggested
The primary mitigation is to upgrade OpenProject installations to version 17.0.2 or later, where the missing authorization check has been implemented. Organizations should audit and restrict the Manage Users permission to only trusted personnel, minimizing the number of users who can exploit this vulnerability. Implement role-based access control (RBAC) policies to enforce the principle of least privilege. Monitor user account lock/unlock activities for unusual patterns that could indicate abuse. Employ multi-factor authentication (MFA) for accounts with elevated privileges to reduce the risk of credential compromise. Regularly review and update security policies related to user management in OpenProject. In environments where immediate upgrade is not feasible, consider temporary compensating controls such as manual oversight of user lock/unlock actions or disabling the Manage Users permission where possible. Maintain up-to-date backups of user and project data to enable recovery in case of disruption.
Description
OpenProject is an open-source, web-based project management software. Prior to 17.0.2, users with the Manage Users permission can lock and unlock users. This functionality should only be possible for users of the application, but they were not supposed to be able to lock application administrators. Due to a missing permission check this logic was not enforced. The problem was fixed in OpenProject 17.0.2The problem was fixed in OpenProject 17.0.2.
