GHSA-F7RX-678F-VF6Q

Vulnerability from github – Published: 2023-10-13 00:30 – Updated: 2024-04-04 08:37

Details

If specific packets reach the Routing-Engine (RE) these will be processed normally even if firewall filters are in place which should have prevented this. This can lead to a limited, increased consumption of resources resulting in a Denial-of-Service (DoS), and unauthorized access.

CVE-2023-44196 is a prerequisite for this issue.

This issue affects Juniper Networks Junos OS Evolved:

21.3-EVO versions prior to 21.3R3-S5-EVO;
21.4-EVO versions prior to 21.4R3-S4-EVO;
22.1-EVO version 22.1R1-EVO and later;
22.2-EVO version 22.2R1-EVO and later;
22.3-EVO versions prior to 22.3R2-S2-EVO, 22.3R3-S1-EVO;
22.4-EVO versions prior to 22.4R3-EVO.

This issue doesn't not affected Junos OS Evolved versions prior to 21.3R1-EVO.

Severity ?

5.4 (Medium)
