What is CVE-2023-37018?

Open5GS MME versions up to 2.6.4 are susceptible to a vulnerability that allows remote attackers to exploit an assertion failure by sending a malformed ASN.1 packet over the S1AP interface. Specifically, an attacker can craft a UE Capability Info Indication message that omits the necessary MME_UE_S1AP_ID field. This can lead to repeated crashes of the MME, effectively causing a denial of service and impacting network operations.
