Base vector

AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions Open5GS MME versions <= 2.6.4

Description The issue is related to 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.

Recommendations For Open5GS MME versions <= 2.6.4, update to a version greater than 2.6.4 to resolve the issue. As a temporary workaround, consider restricting access to the S1AP interface to minimize the risk of exploitation. Avoid sending S1Setup Request messages without the required Global eNB ID field until the issue is resolved.
