Control iD vulnerabilities

Control iD iDSecure versions prior to 4.8.3.0 are affected by an unauthenticated Denial of Service. The /api/dguardintegration/dguardVersion endpoint dereferences DGuard integration login state that may be unset, raising an unhandled null reference exception. The exception is thrown from an asynchronous method that returns void, so it is not observed by a caller and can terminate the iDSecure process.

Control iD iDSecure versions prior to 4.8.3.0 are affected by an unauthenticated Denial of Service. The /api/license/restartService endpoint is reachable without authentication and invokes an internal routine that terminates the iDSecure service process and relaunches it by way of a generated batch script. An unauthenticated remote attacker can call this endpoint repeatedly to hold the service in a continuous restart cycle, rendering it unavailable.
