Descriptions

An issue was discovered in SysAid ITIL 20.4.74 b10. The /enduserreg endpoint is used to register end users anonymously, but does not respect the server-side setting that determines if anonymous users are allowed to register new accounts. Configuring the server-side setting to disable anonymous user registration only hides the client-side registration form. An attacker can still post registration data to create new accounts without prior authentication.

Se ha detectado un problema en SysAid ITIL versión 20.4.74 b10. El endpoint /enduserreg es usado para registrar usuarios finales de forma anónima, pero no respeta la configuración del lado del servidor que determina si los usuarios anónimos pueden registrar nuevas cuentas. La configuración del lado del servidor para deshabilitar el registro de usuarios anónimos sólo oculta el formulario de registro del lado del cliente. Un atacante puede seguir publicando datos de registro para crear nuevas cuentas sin autenticación previa
