FlexRIC v2.0.0 crashes when receiving a duplicate E2_SETUP_REQUEST from the same or spoofed E2 Node. The iApp registry enforces node ID uniqueness via assert() rather than graceful rejection. A remote unauthenticated attacker can crash the iApp process (port 36421) by sending two E2_SETUP_REQUESTs with the same E2 node configuration, triggering SIGABRT.
