Until a fix is available, consider restricting network access to the near-RT RIC process port (36421) to trusted sources only to reduce exposure. Monitor for unusual crashes or restarts of the near-RT RIC process.
Description
FlexRIC v2.0.0 has a vulnerability where certain whitelisted but unimplemented E2AP message types cause the near-RT RIC process to crash due to reachable assert(0) calls. A remote unauthenticated attacker can exploit this by sending a specially crafted E2AP PDU, such as E2nodeConfigurationUpdate, to trigger a SIGABRT and cause a denial of service. The vulnerability does not impact confidentiality or integrity but results in high availability impact. No patch or official remediation guidance is currently available.
