MISP: Missing Authorization Check for Event Sharing Group When Distribution Field Is Omitted During Edit
Vulnerability Description
Affected versions of MISP fail to authorize a submitted sharing group in a specific event-edit path.
The vulnerable logic checked whether the acting user could use a sharing_group_id only when the request explicitly supplied distribution = 4. If the attacker instead omitted distribution but supplied a different sharing_group_id, that authorization branch was skipped. Later, MISP’s field-recovery logic restored the existing event distribution from storage. For events already configured with sharing-group distribution, the unauthorized sharing-group ID could therefore be saved.
The fix adds authorization checks in both the controller and Event::_edit() whenever a non-empty sharing_group_id is supplied without distribution. The model now calls SharingGroup::checkIfAuthorised() before persisting the change.
Version affected: ≤2.5.45

MISP 授权问题漏洞
Vulnerability Description
MISP是MISP组织开源的一个威胁情报共享与分析平台。 MISP 2.5.45及之前版本存在授权问题漏洞,该漏洞源于在特定事件编辑路径中未对提交的共享组进行授权,当省略distribution参数但提供不同sharing_group_id参数时授权分支被跳过,可能导致未授权共享组ID被保存,造成权限控制绕过。
