MISP Core: Mass Assignment and Object Re-ownership via Unvalidated Request Fields
Vulnerability Description
Multiple MISP core controllers and model capture paths accepted client-controlled request fields such as primary keys (id) and ownership/scope foreign keys (event_id, org_id, user_id, sharing_group_id, galaxy_cluster_uuid, organisation_uuid, and related nested object identifiers) without consistently stripping, pinning, or revalidating them against the server-authorized object.
In affected paths, an authenticated user with access to one authorized object could submit crafted REST or form payloads that caused MISP to save data against a different object than the one checked by the authorization logic. Depending on the endpoint, this could allow object overwrite, object re-parenting, ownership transfer, unauthorized sharing-group scoping, event/object injection, proposal retargeting, or stored attacker-controlled content appearing in another user’s context.
The fixes harden affected create/edit/import flows by stripping client-supplied primary keys on create-only saves, re-pinning route- or database-authorized identifiers before save operations, validating effective sharing-group scope, and adding field whitelists where ownership fields must never be editable. The initial broad fix also added a central CRUDComponent::edit() primary-key re-pin so payload-supplied IDs cannot redirect saves away from the already-authorized row. GitHub’s patch for 7acf8220c describes this central issue as CRUDComponent::edit() copying supplied fields, including a payload primary key, onto the loaded record, allowing CakePHP save() to update an arbitrary row unless the loaded ID is re-pinned.

MISP 授权问题漏洞
Vulnerability Description
MISP是MISP组织开源的一套开源的软件解决方案。该产品用于收集、存储、分发、共享网络安全指标,并具有威胁网络安全事件分析和恶意软件分析等功能。 MISP 2.5.41及之前版本存在授权问题漏洞,该漏洞源于核心控制器和模型捕获路径未正确剥离或重新验证客户端控制的请求字段,如主键和所有权/范围外键,可能导致经过身份验证的用户提交特制REST或表单有效载荷,从而造成对象覆盖、对象重新父级化、所有权转移、未授权的共享组范围、事件/对象注入、提案重定向或存储攻击者控制的内容显示在另一个用户上下文。
