What is CVE-2023-37007?

Open5GS MME versions 2.6.4 and earlier are susceptible to a denial of service vulnerability that can be exploited remotely. An attacker can trigger an assertion failure by sending a malformed ASN.1 packet through the S1AP interface, specifically using a Handover Cancel message that omits the required MME_UE_S1AP_ID field. This manipulation can cause the MME to crash repeatedly, leading to a denial of service condition, severely affecting system availability.
