In MISP, the queryEnrichment method in EventsController.php accepted a module name parameter and iterated over the list of enabled modules to find a match. If the specified module was not present in the enabled modules list, the code silently continued processing using default parameters (format set to 'simplified' and no module-specific configuration applied) rather than rejecting the request. This allowed an authenticated user to trigger enrichment or analysis processing through a module that was not explicitly enabled or available on the instance, bypassing the intended module availability controls. The lack of validation meant that module names outside the enabled set were not rejected, potentially exposing functionality or data processing paths that the administrator had not authorized for use.

Ein Angreifer kann mehrere Schwachstellen in MISP ausnutzen, um beliebigen Programmcode auszuführen, um einen Denial of Service Angriff durchzuführen, um Informationen offenzulegen, um Dateien zu manipulieren, um einen Cross-Site Scripting Angriff durchzuführen und um Sicherheitsvorkehrungen zu umgehen.
