Description
A NULL Pointer Dereference vulnerability in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved on ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509 devices allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS). Whenever specific valid multicast traffic is received on any layer 3 interface the evo-pfemand process crashes and restarts. Continued receipt of specific valid multicast traffic results in a sustained Denial of Service (DoS) attack. This issue affects Junos OS Evolved on ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509:  * from 23.2R2-EVO before 23.2R2-S4-EVO,  * from 23.4R1-EVO before 23.4R2-EVO. This issue affects IPv4 and IPv6. This issue does not affect Junos OS Evolved ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509 versions before 23.2R2-EVO.

Executive Summary

This vulnerability is a NULL Pointer Dereference in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved on certain ACX devices. It allows an unauthenticated, adjacent attacker to cause the evo-pfemand process to crash and restart by sending specific valid multicast traffic to any layer 3 interface. Repeated receipt of this traffic results in a sustained Denial of Service (DoS) condition.

Impact Analysis

The vulnerability can cause a Denial of Service (DoS) on affected Juniper devices by crashing and restarting the evo-pfemand process whenever specific multicast traffic is received. This can disrupt network operations and availability on affected devices.

Mitigation Strategies

To mitigate this vulnerability, upgrade Junos OS Evolved on affected devices to versions 23.2R2-S4-EVO or later, or 23.4R2-EVO or later, as these versions contain fixes for the issue. Avoid exposure to specific valid multicast traffic that triggers the evo-pfemand process crash until the upgrade is applied.
