CVE-2023-37017 Details
Description
Open5GS MME versions <= 2.6.4 contain an assertion that can be remotely triggered via a malformed ASN.1 packet over the S1AP interface. An attacker may send an `S1Setup Request` message missing a required `Global eNB ID` field to repeatedly crash the MME, resulting in denial of service.
A denial-of-service vulnerability has been identified in Open5GS MME versions through 2.6.4. The issue arises from an assertion that can be remotely triggered by sending a malformed ASN.1 packet over the S1AP interface. Specifically, an attacker can send an 'S1Setup Request' message that omits the required 'Global eNB ID' field, causing the MME to crash. This exploitation can be repeated, leading to a persistent denial-of-service condition.
Users can upgrade to Open5GS version 2.7.0 or later, where this vulnerability has been fixed.
