Vulnerability Title
MISP: IDOR via Client-Supplied Report ID in Module Results Processing Allows Reparenting and Overwriting of Other Events' Reports
来源: CVE Program / CVE List V5
Vulnerability Description
MISP contains an insecure direct object reference vulnerability in the processModuleResultsData method of the Event model. When processing module results, the code iterates over EventReport entries supplied in the resolved data and saves each one. Unlike the adjacent attribute and object processing loops, the report loop did not unset the client-supplied 'id' field before calling save(). Because the MISP EventReport model's create() method does not strip the id field, an authenticated user with permission to submit module results could include an 'id' value referencing an existing report belonging to a different event. Upon save(), the ORM would update that existing row rather than insert a new one, allowing the attacker to   - read the content of another event's report by reparenting it into their own event  - overwrite the report's fields with attacker-controlled data  - change the report's event_id to redirect ownership.  This constitutes an authorization bypass through a user-controlled key, enabling cross-event data disclosure and integrity compromise. The vulnerability requires an authenticated session with the ability to invoke module result processing on an event. Version affected: <2.5.47
