#VU68277 Input validation error in Juniper Junos OS - CVE-2022-22223


Vulnerability identifier: #VU68277

Vulnerability risk: Medium

CVSSv4.0: 4.9 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-22223

CWE-ID: CWE-20

Exploitation vector: Local network

Exploit availability: No

Vulnerable software:
Juniper Junos OS
Operating systems & Components / Operating system

Vendor: Juniper Networks, Inc.

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of IPv4 and IPv6 packets. A remote attacker can send specially crafted IP packets to the affected device, causing multiple interfaces in the LAG to detach and perform a denial of service (DoS) attack.

Successful exploitation of the vulnerability requires that QFX10000 Series devices using Juniper Networks Junos OS are configured as transit IP/MPLS penultimate hop popping (PHP) nodes with link aggregation group (LAG) interfaces.

Mitigation
Install updates from vendor's website.
