Official description
FlexRIC v2.0.0 contains reachable assert(0) calls in stub message handlers for whitelisted but unimplemented E2AP message types in the near-RT RIC. A remote unauthenticated attacker can send a decodable E2AP PDU of such a type (e.g., E2nodeConfigurationUpdate) to crash the near-RT RIC process (port 36421) via SIGABRT. The message passes whitelist validation but triggers an unconditional assertion in the handler.
