Technical Analysis

Based on the published vulnerability details authentication bypass is possible likely because the DDM service fails to terminate the session as an authentication error is detected, but proceeds to parse subsequent commands incoming from the connection. The commands sent by the attacking client can include instructions for command execution, making this an unauthenticated RCE.
