What is CVE-2023-37006?

Open5GS MME versions prior to 2.6.4 are susceptible to a vulnerability that allows a remote attacker to trigger an assertion failure through a malformed ASN.1 packet sent over the S1AP interface. By exploiting this flaw, an attacker can send specifically crafted 'Handover Request Ack' messages that omit the required 'MME_UE_S1AP_ID' field, causing the MME process to crash repeatedly. This can lead to significant disruptions in service availability.
