An Improper Check for Unusual or Exceptional Conditions in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS Evolved on PTX10003 Series allows an unauthenticated adjacent attacker to cause an impact to the integrity of the system.
When specific transit MPLS packets are received by the PFE, these packets are internally forwarded to the RE. This issue is a prerequisite for CVE-2023-44195.

CVE-2023-44195 [MEDIUM] CWE-923 GHSA-f7rx-678f-vf6q: An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in the NetworkStack agent daemon (nsagentd) of Juniper Networks J
An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in the NetworkStack agent daemon (nsagentd) of Juniper Networks Junos OS Evolved allows an unauthenticated network based attacker to cause limited impact to the availability of the system.
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:

* 21.4-EVO versions prior to 21.4R3-S4-EVO;
* 22.1-EVO version 22.1R1-EVO and later;
