Vulnerability Title
MISP mass assignment vulnerabilities allow unauthorized modification of ownership and delegation records
Vulnerability Description
MISP contained multiple mass assignment vulnerabilities in the handling of collections, tag collections, event delegations, and shadow attributes. Several controller actions accepted user-supplied fields that should have remained server-controlled, including record identifiers and ownership-related fields such as id, org_id, orgc_id, and user_id.
An authenticated attacker with access to the affected endpoints could craft requests containing protected fields in order to alter object ownership, redirect an update to another record, overwrite existing event delegation requests, or modify shadow attribute proposals belonging to another organization. This could result in unauthorized modification of MISP objects and, depending on object visibility and sharing configuration, unauthorized access to or transfer of sensitive threat intelligence data.
The issue was fixed by explicitly pinning ownership and identity fields to their stored values during edit operations and by removing user-supplied primary keys from create-only save paths.
Affected components:
* CollectionsController::edit()
* EventDelegationsController::delegateEvent()
* ShadowAttributesController::edit()
* TagCollectionsController::edit()915
* TagCollectionsController::editWithTags()
Attack requirements:
The attacker must be authenticated and able to reach the affected MISP endpoints. No user interaction is required.

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存在授权问题漏洞,该漏洞源于在处理 collections、tag collections、event delegations 和 shadow attributes 时存在多个批量赋值漏洞。控制器动作接受了应由服务器控制的用户提供字段,包括记录标识符和所有权相关字段(如 id、org_id、orgc_id 和 user_id),可能导致经过身份验证
