Summary
In MISP, an improper authorization vulnerability allowed an organization administrator to access user settings belonging to site administrator accounts within the same organization. The access control checks did not exclude higher-privileged site administrator users, enabling modification of site administrator account settings.
Risk Assessment
This vulnerability could lead to unauthorized access to sensitive information and settings of site administrator accounts, posing a security risk to the entire organization.
Recommendation
It is recommended to apply the latest patch that hardens the access control logic by excluding site administrator accounts from organization administrator-managed user sets.
Original NVD description (English source)
An improper authorization vulnerability in MISP allowed an authenticated organization administrator to access or modify user settings belonging to site administrator accounts within the same organization. The affected access-control checks scoped administrative actions by organization membership but did not exclude higher-privileged site administrator users. As a result, an organization administrator could potentially view or alter site administrator user settings and related login profile information, crossing the intended privilege boundary between organization administration and site-wide administration. The patch hardens the ACL logic by excluding site administrator accounts from organization administrator–managed user sets, adding explicit authorization failure when a target user is not administrable, and ensuring user setting and login profile operations fail closed.
