Camunda 7.24.0 before 7.24.15 contains an incorrect authorization vulnerability in the Admin web application's first-run setup endpoint, where SetupResource incorrectly determines setup availability by counting only direct members of the camunda-admin group rather than recognizing all configured administrators. An unauthenticated remote attacker can exploit this logic flaw to call the setup user-create endpoint and create a new administrator account when the camunda-admin group is empty but the system is fully administered, resulting in account takeover and potential process deployment or script execution as the engine's service user.

DISPUTED Camunda Modeler (aka camunda-modeler) through 4.6.0 allows arbitrary file access. A remote attacker may send a crafted IPC message to the exposed vulnerable ipcRenderer IPC interface, which manipulates the readFile and writeFile APIs. NOTE: the vendor states "The way we secured the app is that it does not allow any remote scripts to be opened, no unsafe scripts to be evaluated, no remote sites to be browsed."
