Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
