What is CVE-2023-37019?

The Open5GS MME contains a vulnerability that allows an attacker to exploit an assertion via a malformed ASN.1 packet sent over the S1AP interface. By sending an S1Setup Request message that lacks the necessary Supported TAs field, an attacker can trigger a condition that leads to repeated crashes of the MME, thereby causing a denial of service. This issue poses significant risks to network availability and requires prompt remediation.
