What is CVE-2023-37017?

The Open5GS MME software versions up to 2.6.4 are susceptible to a denial of service vulnerability that can be exploited through the transmission of malformed ASN.1 packets over the S1AP interface. Specifically, an attacker can craft an S1Setup Request message that omits the mandatory Global eNB ID field, leading to repeated crashes of the MME service. This results in significant disruption and unavailability for users relying on the affected software.
