- Severity: CVSS 8.6 (High), CNA
- Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 9.8.4, 9.9.2.50, 9.10.1.17, 6.2.3.12, 6.3.0.3
- Published: 2019-05-03 · Updated: 2024-11-19

## Affected

- Cisco Cisco Adaptive Security Appliance (ASA) Software: fixed in 9.8.4; fixed in 9.9.2.50; fixed in 9.10.1.17
- Cisco Cisco Firepower Threat Defense (FTD) Software: fixed in 6.2.3.12; fixed in 6.3.0.3

## Description

A vulnerability in the Internet Key Exchange Version 2 Mobility and Multihoming Protocol (MOBIKE) feature for the Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a memory leak or a reload of an affected device that leads to a denial of service (DoS) condition. The vulnerability is due to the incorrect processing of certain MOBIKE packets. An attacker could exploit this vulnerability by sending crafted MOBIKE packets to an affected device to be processed. A successful exploit could cause an affected device to continuously consume memory and eventually reload, resulting in a DoS condition. The MOBIKE feature is supported only for IPv4 addresses.

## What to do

- Check your stack: if you ship or depend on Cisco Cisco Adaptive Security Appliance (ASA) Software, Cisco Cisco Firepower Threat Defense (FTD) Software, upgrade to a fixed version (9.8.4, 9.9.2.50, 9.10.1.17, 6.2.3.12, 6.3.0.3) per the references below.
