| 제목 | Open5GS <=2.7.5 Reachable Assertion |
|---|
| 설명 | In Open5GS AMF versions ≤ v2.7.5, a critical vulnerability allows attackers to crash the AMF service by sending a SIGTERM signal during its initialization phase (specifically after subscription requests to the NRF are sent but before responses are processed). This disrupts the internal state machine, triggering a fatal assertion failure that forcibly terminates the AMF process. Exploiting this flaw causes persistent denial-of-service (DoS) attacks, paralyzing 5G core network services and preventing gNodeBs and UEs from establishing connections. |
