GHSA-P6Q2-W3W9-4CJW

Vulnerability from github – Published: 2025-01-22 15:32 – Updated: 2025-02-07 03:32

Details

The NextEPC MME <= 1.0.1 (fixed in commit a8492c9c5bc0a66c6999cb5a263545b32a4109df) contains a stack-based buffer overflow vulnerability in the Emergency Number List decoding method. An attacker may send a NAS message containing an oversized Emergency Number List value to the MME to overwrite the stack with arbitrary bytes. An attacker with a cellphone connection to any base station managed by the MME may exploit this vulnerability without having to authenticate with the LTE core.

Severity ?

8.9 (High)


                  
                    CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:H
